BMW M5 (E34)

DDE/DRL install on E39

noreply@blogger.com (roy) — Tue, 07 Jul 2009 07:11:00 +0000

So...I've had angel eyes on my car for over a year now. It had bothered me that I never set them up for DRL originally so I sought a solution to my woes and was able to find one.

Originally, I had my AE's powered off of my parking lights. This is a common thing that many people do and I personally didn't think it was cool. At first I was happy to have AE's but after awhile I wanted them as DRL's/DDE's. This is what they looked like before with the setup I had.

I feel that the amber side markers make the setup look cheap and my parking lights in my tail lights were on as well with this setup.

I found out that Umnitza sold a harness that could be setup in DRL and a few other things as well. This is what the harness looks like. I have a suspicion that this harness was designed with the E46 in mind though.

The harness is fairly simple but it's nice because it has an inline fuse and a majority of the wiring is inside heat resistant wrapping which not only makes it look good but keeps things organized.

Step 1:
First thing I did was disconnect the ground from the battery. This is for safety reasons even though this install should not require it. I felt that since I'm going to be grounding wires and tapping into the accessory wire in the ECU compartment it definitely wouldn't hurt to be on the side of caution. I removed the ground using a 10mm socket wrench and then I let the car sit for about 10 minutes to let any extra power disperse.

Step 2:
While letting the car discharge after removing the ground, I proceeded to remove the cabin filter/air box on the passenger side of the car. Removing the box will give you access to the cover of the ECU, which you will need to remove for the next step.

Step 3:
I removed the 4 hex head bolts holding the cover of the ECU on allowing me access the wiring inside.

The wire you will need to tap into is the accessory wire which is half red and half white with yellow hashes on it. I used the supplied T-tap that came with the harness to install the trigger wire. I clamped the T-tap securely down on the accessory wire a set of pliers. Not too much force was required for this but just make sure the wire is sitting in the correct position before you clamp the T-tap into position.

It will look like this once completed.

After installing the T-tap, plug the red wire into the T-tap and you're done with the scary stuff.

Step 4:
The next step of the installation is to find a 12 volt power source and a solid ground. The obvious choice for the power is the jump start terminal and in my installs case I used a bolt on top of the strut tower as the ground.

Remove the jump start terminal bolt using a 3/4" socket wrench. Slide the plastic cap out of the way to allow room to place power cable for the harness under the jump start cable. Place bolt back into hole and tighten in place.

My next step was to find the closest ground. In this case the ground for the jump start terminal is on the opposite side of the engine bay (bad design) so I settled with the strut tower as a ground. I removed the closest bolt and placed the ground in position. I made sure to tighten the bolt on the strut tower as it was when I removed it.

Step 5:
After finding power and a good ground I plugged the harness into the angel eyes and re-secured the ground on the battery in the trunk.

To test the Angel Eyes put key in ignition and turn the key to POS2. If you set everything up correctly the AE's will light up and stay on. If they work then you are done with the install. Now it's time to focus on cleaning up the wiring harness and making sure it's not too visible.

Step 6:

I hid the fuse box and second trigger wire underneath the drivers side air filter box. This compartments houses the brake booster and other cool stuff as well. I made sure to wrap the bare metal end of the second and unused trigger wire with electrical tape as to make sure there would be no problems with short circuiting. I wrapped all bare wire in electrical tape and tried to hide/route the harness so it looked like it belonged to the factory wiring harness.

Install time took roughly 30 minutes with basic hand tools. Cleaning everything up and putting everything back together took an additional 20 minutes. Overall, a very easy install that adds a lot of style.

BMW M History

noreply@blogger.com (roy) — Mon, 06 Jul 2009 12:20:00 +0000

BMW M division is probably the best known and the most successful high performance division of a large automaker worldwide. BMWDrives gives you the chance to discover the BMW M history and every single model launched since the legendary BMW M1. Also you will find the BMW M cars that are under current production. BMW M history is synonymous with Motorsport, racing cars, tough competition and the restless wish to be the best!

1972

Established in May 1972, BMW M GmbH, previously known as BMW Motorsport GmbH, is a division of BMW AG. This high performance division began with just eight employees and it was initially created to handle BMW’s racing program during the 1960s and 1970s.
Their first project was the BMW 3.0 CSL. CSL stands for Coupe Sport Leicht, or Lightweight. 1265 lightweights were built from 1972 to 1975. This famous racer won seven European Touring Car titles.

1973

In 1973 the BMW 3.0 CSL wins the 24 hour race from Nurburgring driven by Hans Joachim Stuck and Chris Amon, two exceptional pilots. Because of the huge aerodynamic wings, the 3.0 CSL was nicknamed "the Batmobile".
In the late 1970s the first modified street legal road cars were produced for the contracted racecar drivers as their personal vehicles.

1978

The first M-badged car that was officially for sale to the public was the beautiful BMW M1 E26, at the Paris Motor Show in 1978. Based on the 1972 BMW Turbo prototype, designed by Paul Bracq, the M1 received its final touches by another famous designer: Giorgetto Giugiaro.

The BMW M1, the first BMW M car to go on sale, has a very interesting story. Because of the lack of resources, BMW approached Lamborghini to develop this car. But the Italians were no able to finish it because of their financial problems so it came back to the German engineers. The M1 was initially designed only for the racetracks and it was planned to race in the German racing championship. Because of development delays a participation in this running series was no longer possible. In co-operation with Bernie Ecclestone and Max Mosley the Procar Series was created. This series was the opening race for many Formula 1 races. But there still was a problem. The cars racing in the Procar Series had to be developed from series production cars. Therefore BMW M GmbH "had" to produce a road car for the M1. Approximately 450 cars were produced and since the beginning they were a collector’s dream.

The M1 E26 road version has a 6-cylinder engine from the 3.0 CSL developing 277 hp. This mid-engined coupe was capable of reaching 165 mph, impressive speeds for 1978. In Group 4 race trim, the M1 had 470 hp and an astonishing 850 hp for Group 5 German Sports Car racing.

1979

Because the BMW M1 E26 was more a racecar with a road car body it was not very suitable for every day use. So, he first real M Series car meant for ordinary drivers was the BMW M535i E12, back in 1979. It was a high performance version of BMW’s popular 5 Series mid-size sedan. It had bigger brakes, Recaro sport seats and was powered by the 6 cylinders M30 engine. This version of the M Series was available until 1981 and BMW sold only 1410 of them.

1983

In 1983 the 6 Series was available also as an M635CSi version with a 3.5 liter, 6-cylinder engine with an output of 286 hp. Now the luxury GT has a sporty and capable engine so the recipe for a superb car is complete.

Developed by the BMW M GmbH, the 4 cylinder turbo engine that equipped the Brabham F1 Team helps Nelson Piquet to win the World Championship.

More and more experience gathered from the race tracks around the world is transferred to the road cars.

1984

The second generation vehicle came into the market in 1984. It was built on the basis of the BMW 5 Series E28 and it was the first M5! The BMW M5 E28 was powered by the S30 engine which had 24 cylinders. This series of M cars were equipped with electric windows, central locking, light alloy wheels and fog lights. All these elements give us a clue about the premium segment where the M cars were targeted. The performance was not neglected. Developing 286 hp in a family sedan was a performance never heard of before. BMW gambled on this combination and the years that followed showed that they were more than right.

1986

1986 is probably the most important in the history of BMW M GmbH. It is the year when the first generation M3 is born! Based on the BMW 3 Series E30, it is regarded even by today’s standards as a benchmark of performance and sheer driving pleasure. From the start, this thoroughbred sports car thrilled not only the motorsport enthusiast and the racing expert, but also car fans the world over. Boasting powerful-looking spoilers and strikingly flared wheel arches all round, the very first BMW M3 was a sensation to behold even at a standstill. The first E30 M3 had a 192 hp 4-cylinder engine which propelled this light car from 0-60 mph in just 6.8 s. The top speed is around 143 mph (230 km/h).
The BMW M3 represents the most successful touring car of all times

1988

By 1988 the BMW M GmbH grew to 400 employees and the demand for the famous M cars was greater than ever. From now on every new generation of 3 Series and 5 Series were available also as an M version.

1995

In 1995 the BMW 8 Series CSi E31 is launched. For this car BMW M GmbH develops the only production V-12 engine ever. It has an output of 380 hp. Although it was never labeled as an M car, the 850 CSi bears the signature of the Motorsport division clearly visible on its engine. BMW was testing a M8 prototype with a special 550 bhp engine. It was intended as a "Ferrari killer" but later on the project was aborted deciding that there was no market for such a car.

1997

Besides the M models from the 3 Series and 5 Series, BMW M presents the Z3 E36/37 M Roadster/Coupe in 1997.

2005

In 2005 the E63 M6 joins the regular M range, having a huge V10 engine with 507 hp under the bonnet.

2007

In 2007, 21 years after the first generation M3, the fourth one comes to life under the body of the E92 M3 Coupé. It continues the tradition of normally aspirated engines but now with twice the number of cylinders and more than double of power.

Since 1978, BMW M has offered modified versions of nearly every car on BMW’s production line, except the 7 Series and the X Sports Utility Vehicles models. Also we have to mention that there were few BMW cars that were developed by M division but they were not labeled M: M535i E12, M635CSi E24 and the 850CSi E31. In spite this they were considered benchmarks of their times and they deserve to share this gallery with the other M models. BMW M GmbH continues to produce some of the most desired and sophisticated tuned street legal cars available in full production. BMW M offers modified engines, suspension, interior trim, aerodynamics and exterior styling. The competitors from Mercedes and Audi fight back with their high performance divisions, the AMG respectively the Quattro. Their models began only by an increase of power to the engines on the standard models and just later on they started to make more extensive modifications as the Bavarians do with the suspension and transmission starting back with the beginning of the 1980s. Although some AMG and RS models have more hp than their Bavarian counter parts some say that they still lack something important: charisma!

The goal of BMW M GmbH is to seed in everyone’s hearts the commitment to perfection and high performance experience taken from the racetracks around the world for more than a quarter of a century. BMW M history is the infallible proof for the big words mentioned above. Many people that had the chance to drive an M model say that the uncompromised driving satisfaction and performance given by these cars is addictive for life.

Versions and Production Numbers

The BMW M5 E34 was produced in two distinct versions, each with several variations. Early cars have a 3.6-liter (actually 3,535cc) version of the 24-valve S38 inline-6 known as the S38 B36. These were built in both left-hand and right-hand drive configurations, as well as a North American-specification edition. There were also a small amount of 3.6-liter M5s assembled in South Africa, exclusively for that market.

Starting in late 1991, the majority of European-spec M5 production (with the exception of some late 3.6-liter cars built for Japan and the Middle East) switched to a 3.8-liter (3,795cc) version of the S38 (designated S38 B38) and gained Adaptive M Suspension, plus a few cosmetic changes. The 3.8-liter M5s were available in both LHD and RHD variations, but there were no North American or South African editions. However, there was a small production run (891 built) of the E34 M5 Touring, or station wagon, all built to 3.8-liter European specification in left-hand drive.

ECE 3.6 (LHD): 5,877 built from 9/88 thru 4/92
ECE 3.6 (RHD): 524 built from 11/89 thru 11/91
NA 3.6 (LHD): 1,678 built from 12/89 thru 4/93
SA 3.6 (RHD): 265 built from CKD kits 9/90 thru 3/93*
ECE 3.8 (LHD): 2,676 built from 12/91 thru 7/95
ECE 3.8 Touring (LHD): 891 built from 3/92 thru 8/95
ECE 3.8 (RHD): 343 built from 12/91 thru 6/95

Evolutions of the BMW M5 E34

Except for minor trim and equipment variations, there were few revisions to the original European-spec E34 M5 during its production. The first major round of changes occurred with the introduction of the more powerful 3.8-liter M5 in late 1991. Along with the larger engine, the 3.8-liter M5 brought Adaptive M Suspension, a reduced-effort clutch and a myriad of cosmetic alterations. Also, the M5 Touring was added at this time.

The final evolution of the E34 M5 entered production in May of 1994 and included the following upgrades:

Getrag Type D six-speed manual gearbox
Enlarged brake rotors with two-piece "floating" front calipers
Nurburgring Package standardized with Servotronic steering as an option
18-inch M Parallel Spoke wheels
Widened front "kidney" grilles with revised hood to match

BMW M GmbH produced 752 examples of the later E34 M5 3.8 six-speed, divided among the following configurations:

ECE 3.8 sedan six-speed (LHD): 404 produced
ECE 3.8 Touring six-speed (LHD): 209 produced
ECE 3.8 sedan six-speed (RHD): 139 produced

Though the E34 M5 was introduced in North America as a 1991 model, production actually began in December of 1989. Cars produced before September of 1990 were therefore built to 1990 specification. Thus. the North American-spec E34 M5 did not actually adopt true 1991 specifications until approximately nine months after production began. At that time, the following items were modified:

Rear center console deleted (became optional in Canada)
Ellipsoid headlights and foglights replaced by "free form" versions
Radio head unit updated to the later version (as used in other 1991 E34 models)
Automatic climate control deleted (only used in some early 1991 E34 M5 examples)
Tilt steering wheel added
Light Silvergray leather upholstery offered in place of Silvergrey

For the 1992 model year (starting 7/91 production) the following changes were introduced:

Rear axle ratio changed from 3.91:1 to 3.73:1 for better fuel economy
Remote locking included as standard equipment
ZF Servotronic (vehicle-speed sensitive) power steering in place of engine-speed sensitive version (USA models only)
Reduced clutch pedal effort
Door sill plates updated to the later design (from 01/92 production)
Calypso Red metallic (252) paint available

For the final 1993 model year (starting 9/92 production), the North American M5 was given some cosmetic updates, many of which were first introduced on the Euro-spec 3.8-liter model:

M System II ("throwing star") wheel covers replace M System I ("turbine")
M-Technic side rear-view mirrors in place of the standard 5 Series versions
Shadowline exterior trim in place of chrome
Front exterior door handles embossed with "BMW Motorsport" text
Birds-eye maple wood trim added in either a gray or black stain (not available in conjunction with the extended leather interior option on Canadian models)
M tri-color stitching added to the airbag steering wheel rim
Brilliant Red (308) paint replaced by Mugello Red (274)
Lagoon Green metallic (266) and Avus Blue metallic (276) paints available (Lagoon Green for USA only)

Drivetrain

The early E34 M5 uses an evolution of the 24-valve inline-six found in the E28 M5 and E24 M635CSi/M6. Designated S38 B36, the engine technically remains a 3.5-liter, with a bore of 93.4mm (same as the previous engine) and a stroke of 86mm (up 2mm on the early S38) for a total capacity of 3535cc (up from 3453cc). The added stroke is due to a new forged steel crankshaft, though the camshafts were also changed. Compression is up slightly (10:1 versus 9.8:1). Further enhancements include:

An electronically-controlled butterfly valve in the inlet manifold to provide better low-rpm and mid-range power
Bosch Motronic fuel injection for precise metering of the air/fuel mixture
Improved flywheel
Equal length stainless steel headers
Three way ceramic catalysts (similar to those used on the M70 V12 engine)

The S38 B36 is rated at 315 hp (DIN) or 310 hp (SAE) at 6,900 rpm and 266 lb/ft of torque at 4,750 rpm. Like the earlier S38 B35, it carries the "BMW M Power" inscription on its cam cover but the design of almost every component is different.

Unlike the engine used in the E28 M5, the S38 B36 engine in the E34 M5 was designed to meet all worldwide emission standards from the start. Therefore, the engines used in North American- and South African-spec E34 M5s are essentially the same as those used in the European-spec models.

The final evolution of the S38 powerplant, the S38 B38, was used in later versions of the E34 M5, none of which were sold in North America. In this application, the bore was increased (to 94.6mm) and the stroke lengthened (to 90mm), raising the displacement to 3,795cc. Though the added capacity makes the S38 B38 the largest six-cylinder production BMW engine of the modern era, it represents only a portion of the major revisions developed by BMW Motorsport at this time. Others include:

Larger intake and exhaust valves
Lighter pistons
Shorter conrods
Increased compression to 10.5:1
Bosch Motronic 3.3 engine management system
Distributorless ignition with six coils
Redesigned intake and exhaust manifolds
Revised throttle butterfly linked to Motronic engine control
Dual-mass flywheel with harmonic balancer
Metal catalysts for reduced backpressure and better heat conduction

The S38 B38 is normally rated at 340 hp (ECE)/347 hp (DIN) at 6,900 rpm and 295 lb/ft of torque at 4,750 rpm. However, a cleaner version was developed for Austria and Switzerland, rated at 334 hp (ECE) and later 327 hp (ECE). The S38 B38 can be identified by its grey (instead of black) cam cover surround.

Gearbox of the BMW M5 E34

All M5s built before May, 1994 have a Getrag 280/5 five-speed manual gearbox with the following ratios: 3.51 (1), 2.08 (2), 1.35 (3), 1.00 (4), 0.81 (5). These cars have a 3.91:1 final drive, with the exception of North American-spec E34 M5s built to 1992 and 1993 specification which have a taller 3.73:1 final drive for better fuel economy.

As of May, 1994 production, the five-speed was replaced with a Getrag Type D six-speed manual box with the following ratios: 4.23 (1), 2.52 (2), 1.66 (3), 1.22 (4), 1.00 (5), 0.83 (6). A taller 3.23:1 final drive was fitted at this time.

All E34 M5s have a standard limited slip differential with a maximum locking of 25 percent.

Chassis

The E34 M5’s chassis is based on the MacPherson strut/semi-trailing arm design of the normal E34 5 Series but incorporates the following changes from BMW Motorsport:

20mm reduction in ride height
25 percent firmer spring rates
Firmer shock valving all around and self-leveling in the rear
Thicker antiroll bars (25mm vs. 23mm in the front, 18mm vs. 15mm in the rear)
Adjustable rear toe-in

All 3.8-liter M5s are further fitted with the Adaptive M Suspension, an M-tuned version of the Electronic Damping Control system that was introduced in the E32 7 Series. This system electronically chooses the optimum shock rates based on sensors that gather road speed, steering input, acceleration/deceleration loads and lateral body movements. Furthermore, M5s equipped with the Nurburgring package (standard from May, 1994) have a control switch on the dashboard to lock the Adaptive M Suspension into the firmest setting during aggressive driving.

Steering

Like all E34 5 Series, the E34 M5 uses a recirculating ball steering design, but the overall ratio is reduced from 16.2:1 to 15.6:1.

Two types of power assistance were offered: An engine-speed sensitive system was fitted to all European-spec 3.6-liter M5s and on North American models built before September, 1991. A vehicle-speed sensitive system developed by ZF and called Servotronic was available on European-spec 3.8-liter models as either a stand-alone option or as part of the optional Nurburgring Package. However, Servotronic was not included with the Nurburgring Package after it became standard equipment in May of 1994, but continued to be a vailable as an individual option. Servotronic was also fitted as standard to all North American-spec M5s built after September, 1991 (i.e. 1992 and 1993 model years).

Nurburgring Package

In addition to the standard Adaptive M Suspension fitted to all 3.8-liter M5s, the Nurburgring Package could be added as an extra cost option. This consisted of ZF Servotronic (vehicle-speed sensitive) power steering, a 19mm rear anti-roll bar, wider 255/40ZR17 rear tires on 9x17-inch alloy wheels (already standard on the Touring) and a control switch for the adjustable shocks that allowed them to be locked in the firmest position. This package became standard on all M5s as of May, 1994 production, with the exception of the Servotronic steering which became a separate option at this time.

Brakes

All M5s built before May, 1994 have upgraded vented front disc brakes measuring 12.4-inches. The rear rotors measure 11.8-inches in diameter and are vented as of 10/89 production. The May, 1994 update brought even larger front and rear brakes (now 13.6-inches and 12.8-inches, respectively) and the front rotors were changed to a two-piece "floating" design for better heat dissipation.

Wheels and tyres

There are two factory 17-inch wheels for the E34 M5, M System I and M System II. Both are a two-piece wheel with a forged five-spoke center and a cast rim covered by an outer cover. The only difference is the design of the outer cover, "turbine" for the M System I and "throwing star" for the M System II. This outer cover is interchangeable between the two M System wheels, making updating form the earlier style to the later style an easy (and therefore common) procedure.

The 3.6-liter M5 is equipped with 235/45ZR17 tires on 8x17-inch M System I wheels. However, for the 1993 model year, North American-spec M5s use the M System II design in the same size. In addition, wider 255/40ZR17 rear tires on 9x17-inch M System I wheels were available as an option in some markets (not North America).

All 3.8-liter M5 sedans built before May, 1994 are equipped with 235/45ZR17 tires on 8x17-inch M System II wheels. Sedans equipped with the optional Nurburgring Package and all Tourings use wider 255/40ZR17 rear tires on 9x17-inch M System II wheels.

All M5s built after May, 1994 have 245/45ZR18 tires on all four corners with staggered M Parallel Spoke wheels measuring 8x18-inches in the front and 9x18-inches in the rear. Note: Though nearly identical in style to the 18-inch M Parallel Spoke wheels later used on the E38 7 Series, the E34 M5 wheels have a matte silver finish and a unique offset.

Cosmetics

An E34 M5 is most easily distinguished from a normal 5 Series by its unique lower body panels that include a front airdam, side valances and rear diffuser. These are painted in a contrasting Diamond Black metallic (181), Sebring Grey metallic (229) or Granite Silver metallic (237), depending on the car’s exterior color and production date. In addition, the E34 M5 has large-diameter twin exhaust pipes and "M5" grille and decklid badges (only the former on M5s built after May, 1994). Like the previous E28 M5, these could be deleted upon request. Dechromed window trim (known as Shadowline) was optional on the E34 M5 in most markets, as was a body-color rear decklid spoiler. Starting with the production of the 3.8-liter model, the E34 M5 could be ordered (in most markets) with aerodynamic M rear-view mirrors (also fitted to all North American-spec E34 M5s for the 1993 model year). All E34 M5 sedans have a black plastic panel that fills in the gap between the taillights and the license plate. Though this panel was only fitted to M5 sedans, this same area on the M5 E34 Touring is covered in an exclusive textured black paint (instead of the normal body-color).

The E34 M5 was also the only regular production 5 Series to be fitted from the factory with 17-inch M alloy wheels in either a "turbine" style known as M System I (all 3.6-liter models and North American-spec cars up to 9/92) or a "throwing star" design known as M System II (all 3.8-liter cars up to 5/94 and North American-spec after 9/92). The final six-speed 3.8-liter M5s (from 5/94) use an 18-inch M Parallel Spoke design, also essentially unique to the M5 within the E34 range.

European version vs. North American versions vs. South African version

Aside from government-mandated safety features such as bumper-mounted side marker lights, North American cars are visually very similar to their Euro-market counterparts. The sole exception are 1993 models (built from 09/92-03/93). These have the exterior appearance of the European-spec 3.8-liter M5, but retain the 3.6-liter engine and chassis.

The South African-built M5s are cosmetically identical to the European-spec cars. However, like the South African-spec E28 M5s, their bodies were painted at BMW's Rosslyn factory, thus exterior paint choices may have been limited.

The wheels are the main exterior differentiator between a 3.6-liter E34 M5 and a later 3.8-liter model. The European-spec 3.6-liter M5s were all equipped with the M System I ("turbine") wheel design, while the 3.8 utilized the M system II ("throwing star") version until April, 1994. At that point, all M5s were upgraded to the 18-inch M Parallel Spoke wheels. (Note: North American-spec 1993 M5s use the later M System II wheel even though they are powered by the earlier 3.6-liter engine.)

In addition, the contrasting color of the lower aerodynamic body panels differed between the 3.6-liter and 3.8-liter M5 models. On the 3.6-liter examples ,these were painted either Diamond Black metallic (181) or Sebring Grey metallic (229). This changed with the 3.8-liter version to a choice of either Diamond Black metallic (181) or Granite Silver metallic (237). (Note: the change from Sebring Grey to Granite Silver also applies to the 1993 North American-spec E34 M5, which retained the 3.6-liter motor.)

Interior

Though the basic architecture of the interior is identical to that of any E34 5 Series, the M5 interior does have a few unique items: The unique instrument cluster contains red needles, an oil temperature gauge under the tachometer (instead of an economy gauge) and an M logo between the speedometer and tachometer. Like the E28 M5, there are "M5" trim plates on all four door sills (in one of two versions, depending upon the production date) and a fully-carpeted trunk with a storage compartment on the left side.

All E34 M5s are equipped with sport front seats, identical in shape and adjustment to those fitted as an option to other E34 5 Series models. Power controls were either standard or optional, depending upon the year and market. On European-spec M5s, the seats could be upholstered in a unique M cloth with leather boolsters on 3.6-lier models or a different M cloth with Amaretta suede bolsters on 3.8-liter models, as well as optional leather. Also, all E34 M5s built before September, 1990 have a fixed rear center console that effectively makes them four-seaters. This console became optional in most markets starting with September, 1990 production.

There were five different factory steering wheels available on the E34 M5, depending on the market and production date. Most 3.6-liter models and some early 3.8-liter cars have the three-spoke M-Technic II steering wheel without an airbag but with the M logo on the third spoke. Standard on U.S.-spec M5s and optional in most other markets (including Canada) was the regular airbag-equipped four-spoke BMW wheel. Starting with September, 1992 production, this wheel was upgraded to include the M tri-color stitching on the rim. Beginning with the 1994 model year (09/93 production), E34 M5s could be fitted with either an M-enhanced version of the four-spoke airbag wheel, now including a thicker rim with thumb grips and a revised center pad, or a new non-M three-spoke wheel with an integrated Euro-sized airbag. A leather-wrapped shift knob with an illuminated shift pattern and the M tri-color stripe was fitted as standard to all E34 M5s. Also, the area around the shift lever is unique in that it is recessed for extra storage.

Finally, all E34 M5s have a check control vehicle monitoring system integrated into the instrument cluster and the fourth-generation BMW on-board computer.

The interior of the 3.8-liter E34 M5 is essentially identical to the one found in 3.6-liter models. The main exception concerns the standard cloth upholstery. Early (3.6-liter) E34 M5s that are not equipped with optional leather upholstery have M cloth seats and door panels with leather on the outer bolsters, while the later (3.8-liter) cars have a different type of M cloth on the center part of the seats and door panels with a suede-like Amaretta material on the bolsters.

Also, 3.8-liter M5s have more pronounced door sill plates with the "M5" logo in a style similar to that of the E36 M3. (Note: North American-spec M5s built after 01/92 also have this design.)

Optional equipment

Like most other M models, the level of standard and optional equipment for the E34 M5 varies significantly from year to year and market to market. Major exterior options (standard in some markets) include power sunroof, metallic paint, heated headlight washers, Shadowline (dechromed) trim and a body-color rear spoiler. Like the E28 M5, the E34 M5's hand-built nature allowed even more variation on the interior. All regular E34 options were available, as well as various special types of upholstery, dash and console trims, and luxury items such as upgraded audio systems, phones, fax machines and televisions.

These special-order items were generally not availble in the North American market, where the E34 M5's option list was confined to heated front seats (standard in Canada), a CD changer, integrated cellular phone and remote locking with alarm (standard from 9/91 production) . One further rare option was the "Four-Seasons" glass moonroof, discontinued as of September, 1990. In addition, Canadian cars could further be fitted with a three-position memory for the driver's power seat and power steering column, extended leather upholstery and the fixed rear center console (standard on all North American cars built before September, 1990).

Special Versions

There were four official special editions of the E34 M5 sedan: The Cecotto, Winkelhock and "20 Jahre" editions were offered exclusively as left-hand drive European-spec models, while the right-hand drive UK Limited Edition was only sold in the United Kingdom.

"Naghi Motors" edition

At the request of Naghi Motors, the BMW importer for Saudi Arabia, BMW Motorsport GmbH produced 15 special examples of the 3.6-liter E34 M5 sedan. Known as the "Naghi" edition, these were the final ECE-spec 3.6-liter M5s produced. and were all built in late March and early April of 1992. Like all Gulf-specification E34 M5s, they were built without catalysts and were therefore rated at 318 hp (DIN).

What You Should Know About BMW M5 (E34)?

noreply@blogger.com (roy) — Mon, 06 Jul 2009 05:23:00 +0000

The E34 M5 is a continuation of BMW's M5 series of sports sedans, based on the 5-series. It was produced from 1988 to 1995, although sales in North America started in 1990 and ended in 1993. It was produced at BMW M GmbH in Garching, Germany and like the previous M5, was entirely hand-built. It utilized the 535i chassis which was produced at BMW's Dingolfing plant. Assembly was done either by a single M employee or a team of M employees and generally took about two weeks. It is rumored that the test drivers of the E34 M5 could determine who or what team made each specific M5, due to characteristic quirks of the handbuilt nature of the E34 M5. The engines were also built by hand by BMW M technicians. All of the E34 M5 powerplants were built to 5% of advertised output.

Overview

The early E34 M5 used an evolution of the 24-valve I6 found in the E28 M5 and E24 M635CSi/M6. Designated S38B36, the engine technically remains a 3.5 L, with a bore of 93.4 mm and stroke of 86 mm for a total capacity of 3535 cc. The added stroke is due to a new forged steel crankshaft, though the camshafts were also changed. Compression was up slightly (10:1 versus 9.8:1). Other adjustments made included an electronically controlled butterfly valve in the intake plenum which provided better low rpm and mid-range power. The engine also featured an improved flywheel, Bosch Motronic fuel injection, equal length stainless steel headers and three way ceramic catalysts.

Originally it had a displacement of 3.6 L and produced 315 hp (235 kW) at 6900 rpm, and 266 ft·lbf (361 N·m) at 4750 rpm. Cars sold in North America and Switzerland which, due to a different catalytic converter, produced 310 hp (229 kW) and 265 ft·lbf (359 N·m).

In 1992, the engine displacement was increased to 3.8 L with the S38B38, except in North America, which continued with the 3.6 L engine. Power was now increased to 340 PS (335 hp/250 kW). Also in 1992, a Touring version was introduced in LHD form only.

The M5 came with an unusual wheel design. From 1988-1992 the M5 featured the M-System wheels. These wheels were 8x17J, but came with directional bolted-on wheel covers. Under the cover was a black 5-spoke alloy wheel. The press was critical of the design, often claiming it gave the M5 the appearance of having "white-wall" tires. In 1992 BMW changed the design and a new cover was produced – the M-System II. The original intent of the M-System cover was to direct more air to the brake assembly to increase cooling. The cover actually integrated a fin assembly behind the cover. The M-System II covers, known as the "throwing stars" did not have as much capability to direct air to the brake assemblies. In May 1994, the M5 came with M Parallel wheels that did away with the cover.

Special versions

There were four special editions of the E34 M5. The Cecotto, Winkelhock and 20 Jahre editions which were offered as LHD Euro specification models while the RHD UK Limited edition was only sold in the United Kingdom.

E34 M5 Cecotto Edition

In 1991, BMW asked two racing drivers to design their "ideal" version of the E34 M5. Johnny Cecotto was one of the drivers and he wanted a host of luxury items fitted on the M5. Including Nappa leather trim for the steering wheel and heated seats.

A total of 22 Cecotto E34 M5s were produced with options of having either Lagoon Green metallic (266) and Mauritius Blue metallic paint (287).

E34 M5 Winkelhock Edition

The other racing driver was touring car ace Joachim Winkelhock. He wanted a lightweight E34 M5 and so some luxury items were removed. His ideal lightweight version M5 featured a smaller battery and the US-spec 81L fuel tank as well as reduced sound deadening and the deletion of some non essential interior items such as rear head rests and vanity mirrors. Recaro front seats and a suede 385 mm M-Technic II steering wheel, shift knob & parking brake lever. The seat design, suede-covered appointments & red seatbelts were similar to those on the Sport Evo E30 M3.

A total of 51 Winkelhock E34 M5s were produced with the options of having Jet Black (668) with contrasting lower body panels in Sterling Silver metallic paint (244).

E34 M5 20 Jahre Motorsport Edition

To celebrate BMW Motorsport 20th anniversary, BMW had built 20 specially equipped Euro-spec M5s in late 1992. These, based on the 3.8 L engine were only in Mugello Red (274) and had a number of aesthetic trim upgrades such as carbon fiber dash panels and special rear view mirrors. Unique seat center & door trim fabric was matched with Alcantara. Alcantara waas also used on the steering wheel, shift lever & parking brake lever. Red seatbelts with "BMW Motorsport" were also included.

E34 M5 UK Limited Edition

To commemorate the end of right-hand drive E34 M5 production, 50 examples of the E34 M5 Limited Edition were assembled between March and June 1995 in one of two unique color and trim combinations: Rosso Red metallic (369) with a Champagne extended leather interior and natural poplar wood trim (15 built) or Orinoco metallic (406) with a Bicolor Petrol and Mint extended leather interior and graphite bird's-eye maple wood trim (35 built). Each E34 M5 Limited Edition is equipped with the three-spoke sport steering wheel, Shadowline trim, power sunroof, power front seats, headlight washers and manual air conditioning. A numbered plaque appears on the center console. (Source: bmwmregistry)

Motorsport

The M5 has never been a popular choice for motorsport due to its size and weight. However, VDS Racing Adventures^[1] have used an E34 M5 in endurance racing, where weight and nimbleness is less important than in sprint racing. The car features many one-off components, including a wide-arch fibreglass bodykit, but the engine is based on the 3.8-litre S38 straight-six and is almost standard, producing approximately 350bhp. It has also raced in the Belgium Belcar Championship, where it was runner up in 2001.
