Excellent writup from: http://www.pixelmapuk.co.uk/cars/Citroen_C1/

I have saved the text here in cause the homepage disapears.. As they tend to do after a while..

"Where the Citroen C1 came from
The Citroen C1 came out in 2005 as a result of Toyota wanting to break into the A-sector of the European market.
Daihatsu developed the 3-cylinder engine and the car is based on the Toyota Aygo. See the Autocar article from June 2005.

PSA Peugeot Citroën and Toyota Motor Corporation (TMC) announced today that after three years of productive collaboration they are getting closer to realizing the fruit of their joint project to design, develop and produce three all-new small passenger cars for the European market. To mark their progress so far, the two companies decided to give faces to the already named Peugeot 107, Toyota Aygo and Citroën C1 by making available the first-ever official photograph of these modern four-passenger vehicles, which are set for a 2005 sales launch and their world unveiling at the Geneva Motor Show in March.

While they share a large number of structural components, parts and sub-assemblies, the Peugeot 107, Toyota Aygo and Citroën C1 each have unique body styles that express the personalities of the Peugeot, Citroën and Toyota marques.

All three vehicles measure about 3.4 meters long, 1.6 meters wide and 1.4 meters high (details in chart). Powered by the latest generation 1.0-liter gasoline and 1.4-liter diesel engines, the compact, fuel-efficient cars also feature advanced safety and environmental protection technologies. These three new models will offer an engaging driving experience in the urban environment. The cars are primarily designed for European markets, where demand for this type of entry-level vehicle is expected to increase.

Developed on a common platform, all three cars will begin rolling off the line at the Toyota Peugeot Citroën Automobile (TPCA) plant in Kolín, Czech Republic in 2005. Vehicle development and plant construction have proceeded on schedule, as announced by both companies in July 2001. The plant will have an annual production capacity of 300,000 vehicles; 200,000 units for Peugeot and Citroën and 100,000 for Toyota.

The project is expected to contribute widely to the local community in terms of direct and indirect employment. It has already created 1,500 jobs at TPCA, with 1,500 more people expected to be hired for a total of 3,000. Total investment, including research and development and production start-up costs, is estimated at € 1.5 billion.

Brand Length Width Height
Peugeot 3428mm 1630mm 1470mm
Toyota 3405mm 1615mm 1465mm
Citroën 3429mm 1630mm 1470mm

This petrol engine uses a combination of technologies to deliver competitive performance, fuel economy and low emissions. A key development target was to achieve a low weight. The engine has an all-aluminium construction and features extra-slim cylinder bores. The air intake system and engine cover are integrated, while further weight-savings are made by producing some components in resin instead of metal. As a result, the engine tips the scales at 67kg, being amongst the lightest internal combustion engine's available on the car market. It is also one of the most powerful 1.0-litre engine's, producing 67bhp, and torque of up to 68 lb-ft at 3,600rpm. The Aygo will accelerate from 0-62mph in 14.2 seconds and has a top speed, where permitted, of 98mph.

Developed to provide performance well-suited to the stop-start driving common to urban areas, with higher levels of low to mid-range torque than on the 1.0-litre VVT-i engine used in the Yaris. Longer spark plugs give better anti-knock performance, in conjunction with VVT-i, which constantly adjusts valve timing to produce both high torque at low engine speeds and more power at higher revs. Reducing the number of cylinders from four to three also improves torque performance in the low to mid-range. The three-cylinder configuration also contributes to reducing the overall amount of friction, as there are fewer moving parts than in a four-cylinder engine. As a result the 1.0 Aygo achieves combined cycle fuel consumption and CO2 emissions, at 61.4mpg and 109g/km respectively.

The engine mounting system has been improved to substantially reduce the levels of noise, vibration and harshness. Instead of the conventional three-mount design, the Aygo uses a mount on each side, positioned on a line passing through the engine's centre of gravity. The third mount at the bottom of the engine compartment is replaced by a torque rod that efficiently suppresses the engine's rotational movement, reducing vibration.

Practical and easy to park, the Aygo measures 3,405mm long, making it one of the shortest four-seaters on the market, with particularly short front and rear overhangs. Add to that an ultra-narrow 4.73m turning radius to make maneuvering in traffic and fitting into parking spaces too tight for most cars. With the wheels pushed out to the corners of the body, Toyota engineers have been able to make better use of interior space and increase the car's stability at higher speeds, so it is capable on the open road, too.

The front suspension is a development of the MacPherson system used on the Yaris. It features L-shaped arms with a higher castor angle and improved anti-dive characteristics. The damping rate of the shock absorbers and the coil springs have been adjusted to deliver a good level of driving comfort.

As on Yaris, a torsion beam is deployed at the rear, but instead is designed to feature a transverse bar with an inverted 'V' profile. This brings considerable weight-saving as the anti-roll bar is integrated into the beam rather than being a separate component. A further development sees the trailing arm bushing set at an angle to the axle, creating a toe correction action.

All Aygo models are equipped with Electric Power Steering (EPS). EPS is speed-sensitive, adapting in line with data from the car's ABS speed sensors. This means the steering has a light feel at low speeds, such as when moving in city traffic or maneuvering into a parking space, and a firmer response at high speeds. EPS also yields benefits in fuel economy, being three per cent more fuel-efficient than a conventional hydraulic power steering system. This is because EPS only operates when the driver makes a steering action, whereas for hydraulic assistance the pump is permanently engaged by the engine. EPS efficiently damps impacts from the suspension, reducing the amount of kickback and vibration felt through the steering wheel.

All Aygo models are fitted with the Bosch ABS8 system with Electronic Brakeforce Distribution (EBD) to ensure the best balance of front and rear braking power in all conditions. The ABS actuator is 36 per cent lighter and more compact than in previous systems. This version of Bosch's ABS features active speed sensors that are more precise than the passive type and are able to monitor low speed and reverse manoeuvres. The Aygo employs 247mm ventilated discs at the front and 200mm drums at the rear, providing ample stopping power for a vehicle that weighs only 790kg."

Two videos showing the new version av Peugeot 107, release in 2012. Some sight says 2013.

MMT Automatic - Toyota Aygo, Citroen C1, Peugeot 107

2012-01-31T21:03:00.001+01:00

But there is no clutch foot SENSITIVE more but an insensitive electric motor.
How to adjust to the?
1. farmers Method: recalibration.
2. Second the "good" solution: a new control unit.

I think there is a MMT update:

Here is the part number of the old control unit:
TOYOTA 89 530 – 700 10 … 6 L 01
AISIN 32 48 11 – 11 090
Here is the part number of the new control unit:
TOYOTA 89 530 – 700 90

Acoording to a user: With the new controller is the car as another car ...
Switches extremely smoothly without any lag ... both in automatic mode or manually

The New Aygo, C1 and 107 Facelift 2012

2012-01-08T05:41:00.001+01:00

I have found some pictures of the new 2012 Toyota Aygo, Citroen C1 and Peugeot 107.

This looks like a facelift of the earlier cars. There are some changes but I don´t think they have change so much. The engine seems to be more enviromental friendly and Toyota claims this new version runs more quite. Peugeot still calls this model 107, and there have been rumour since a while that the new version shall be called 108, so this is just a facelift.

The three cylinder engine1.0i is improved fuel economy. Emissions are also improved, to just 99g/km of CO2

Inside the car, each car has upgraded levels of equipment. An optional MP3-compatible stereo with Bluetooth, a USB port, and a stereo jack input is available on selected versions. This is good.

Other news i that the Electronic Gearbox System with comes with steering-mounted paddles.

For the manual gearbox versions they seem to get a new gearstick look. A Leather/Alcantara® option seems to be available, a guess depending whish country. This has previously been available on the Aygo version here in Sweden.
I have however not seen any picture of the interior, but it is sad that a radio offering has been enhanced by a new facia matching the styling of the dashboard. Featuring a time display. Will be interesting to se how this looks.

Here are som picture taken from Teknikens värld homepage, i think the images can be distributed freely?

Peugoet 107 2012 facelift

Known problems, Aygo, C1, and the Peugeot 107

2011-12-27T21:12:00.005+01:00

People reviewing this car really like them or they don´t, there is really nothing in between. Some have had many problems and some doesnt have any and are enjoying the car.

Earier models has had some problems with engine start (startmotor).
A fix: putting a timer on the startrelay has been supplied to some of the owners. This makes it impossible to run the startengine to long (the startrelay timer stops it), and burn the electric motor.

Many users report having problem with weak clutch mostly pre 2009 (facelift), (its a very common problem its the three wee straps that snap off one by one), then they fitted a Yaris clutch 190 mm instead of 180 mm diameter which does seam to hold together better (but still reading about lots of clutch problmens on the forums). Other known problems have been water intrusion and leaking waterpump on earlier models, also often resulting i beltfan replacement, pre facelift.
squeaky noise after clutch or hearing a grinding sound from the clutch. Common problems is release bearing / pressure plate failure, clutch metal springs failing . Pilot bearing broken and the case that holds the disk can be broken too but from inside not the outside teethes.

somewhere in the shift linkage. Possible that there is not enough lubrication

problem with a wheel bearing problem with a wheel bearing

pre-October 2008 107 models. In it they’ve recommended that the original 180mm clutch be replaced by a 190mm clutch to rectify premature wear, noise. and smell. They also recommend that the flywheel is checked due to fitting of a larger diameter clutch, and if required this also needs to be replaced.

water where the spare wheel goes in the back

The water comes in through the vents behind the rear bumper usually, generally the seal has split
Also check the seals of the lights, high level brake light, and the vent/hole under the catch inside the boot, then that leaves only the hatchback welt, or perhaps leakage from around the rear wiper spindle.

Some have reported MMT problems, I found this in a german forum:
Here is the part number of the old control unit:
TOYOTA 89 530 – 700 10 … 6 L 01
AISIN 32 48 11 – 11 090 Here is the part number of the new control unit:

TOYOTA 89 530 – 700 90

rust forming on the underside of the car is crazy; exhaust especially rust.

headlight go on the side of the road as the bumper needs to be removed to replace the bulb

the interior light only come on when the driver’s door is opened

for an example the right window, which can’t be moved from the drivers side. Was it a problem to put a second switch somewhere in reach point of the driver?

electric power steering ECU can break down, quite expensive to replace.

common problems are; poor door seals letting in water, front brake discs that corrode & wear prematurely & front windscreen wiper blades that only last a year

Engine
Petrol: 1KR-FE (gearbox: C551, C551A)
Piston slap, some cars rattled when cold and the engine has to be replaced.
Piston slap is when the piston has too much play against its cylinder bores. the piston moves too freely in the cylinder instead of tight. You could lose compression in cylinders as well. An indication of piston slap is a decrease in noise as the engine warms up
3 cylinder engine, vibrate a lot and the friction coated piston gets lost the rattle begins to come.

Cost calculation by Adac - Aygo second place, Kia Picanto 1.0 first

2011-12-23T14:37:00.000+01:00

The Triplets gets rated quite high in the car cost calculation list that Adac presents for minicars (kleinwagen). The Kia Picanto Attract with the 3 cylinder 1.0 winns. The Picanto uses the new Kappa 1.0 with Dual-CVVT technology. The engine also uses timing chain instead of belt, a big plus for me. The Kappa is using methods to reduce friction. A nice engine, which uses much of the same technology as the designed Daihatsu engine in the Toyota Aygo, Citroen C1 and Peugeot 107, which came to market 2005.
However, I dont like the ISG system (Idle Stop&Go). The ISG system automatically switches the engine off when the car is stopped in traffic and restarts the engine instantly when the driver wishes to move again, however looking on this with an engineers eyes, this should reduce the life of the start engine (don´t know which type this electric motor is) and tear the cogs at the flywheels. I would prefer to have a choice if I want to use it or not. A switch or something.

Waterpump problems - leaking - Replace with better part

2011-12-20T11:15:00.000+01:00

This information is ONLY for the petrol version (1KRFE engine), NOT the Diesel ( with waterpump SU001-00596).

The older models pre facelift has a bad waterpump construction. I think this was fixed when the new facelift version was released, around 2009.

Disclaimer: The information has been gathered trough Internet. I take no responsibility of the correctness of this post, do your own diligence.

The earlier versions of the triplets (Aygo, C1, 107) have had a bad engineering construction of the water pump. Many problems of leaking has been reported, this may cause failure of engine if not sorted out in time. This post is trying to sort out what kind of version of the water pump there is.

I think there are three versions available:

Mk1

version 24-1020 with metal sheet housing suitable for OE:

Toyota/Daihatsu 16100-09240, 16100-80003, 16100-09450, 16100-80001, 16100-97234/

Citroen-Peugeot 1201.H0

The metal sheet version has been supplied till 2009, the seal eventually will start to leak, checking the presence and condition of the seal will have to be done if the waterpump not has been changed yet and you are still on the first version of water pump.

Mk2

Some people claim there has been a Mk2 version, I don’t know anything about it. 16100-80007, this might be the same as the Mk3 version.. One person claims that this part I pressed and not as good as the Mk3. I would guess it might be casted or made in a CNC-machine.

Mk3

(this is the latest version, and has bolts of different lengths) manufactured from die casting, making it stronger and prevents leaking (thicker aluminum flange).. The torch setting for the bolts is 28 Nm.

version 24-1020 with aluminum housing suitable for OE:

Toyota/Daihatsu 16100-09530, 16100-80007/ Citroen-Peugeot 1201.L3

The water pump must be fixed on the engine block exclusively by means of the rights bolts because of the different thickness of the aluminum housing. Bolts length: 50mm, 45mm, and 20mm.

So if you are going to replace your waterpump, then the latest pump part number for later models (2005> is:

Toyota Water Pump 16100-09530

BoltsBolts 91551-00820 Qty 2
Bolt 91551-00845 Qty 1
Bolt 91551-00850 Qty 2

Pictures of the better construction (Mk3 version):

This waterpump fits:

Citroen C1 1.0 (ref. no. 1201.L3, 1201.J0)

Daihatsu Cuore VIII 1.0 / Sirion 1.0 (ref. no. 16100-80001)

Peugeot 107 1.0 (ref. no. 1201.L3, 1201.J0)

Subaru Justy 1.0 (ref. no 16100-80003)

Toyota Aygo 1.0 / Yaris 1.0 (ref. no. 16100-09530)

I would say: Go for the Toyota number, perhaps their parts comes from Quinton Hazel? Anyways there are waterpumps available from Quinton Hazel also. Fox example: QCP3667 (similar to the Mk3 version) ((BxHxT mm): 185x125x125 : 1050g )

Avoid: QCP3631 (looks like the first version, Mk1) (BxHxT mm): 185x125x125 weight: 900g )

987691 (BxHxT mm): 140x115x115, weight : 1060g ) (perhaps this is the Mk2 version??)

Dismanteling Toyota Aygo in five hours

2011-12-20T07:32:00.000+01:00

Three young men dismantled a Toyota Aygo in a couple of hours (5). The only help to guide was their course leader. This shows how simple the construction really is. Everything is made to be quick to assemble in the Kolin factory. Time is money..

To show the model’s fundamental simplicity, a team of apprentice technicians from Aylesbury Young Offenders Institution succeeded in reducing a regular road-going Aygo to its component parts in just five hours.

They used only standard tools and they had not worked on the Aygo model ever before according to this article.

Pictures taken from:

http://www.toyotagb-press.co.uk/protected/vehicles/releases/2005/38523toy.htm

The Toyota engineer has really tried to use a simpler construction techniques, and that are key factors in achieving the best possible fuel economy. The car is really light, and the simple construction techniques makes it lose weight compared to other traditionally engineered cars.

For example the Yaris has 12 parts in its tailgate, vs. the Aygos tailgate uses glass and just one simple holder for the tailgate. This reduces weight (about 4 kg compared to the Yaris tailgate).

Continuing the comparison, on the five-door model of the Aygo, the rear doors each use seven fewer parts than on the Yaris. This i said to reduced the weight about 4 kg. This simple construction this saves weight, for example inside the car, the front seats with integrated headrests also have fewer components and probably weigh less than the Yaris seats.

The car is still tough: The car has got a 4 four-star rating for passenger crash protection in the official Euro NCAP testing.

Adac statistic for the Triplets: Aygo, 107, C1

2011-12-18T19:59:00.000+01:00

The Triplets: Toyota Aygo, Citroen C1, Peugeot 107 statistic Adac 2010 (kleinwagen), minicars

It is always interresting to follow statistics from the german car club ADAC with 17 millions members (june 2010) has to say (Allgemeiner Deutscher Automobil-Club e.V.)

The Toyota Aygo got first place, probably because of better support by the Toyota sellers.

Problems reported by Adac:

Bad battery

Broken start engine (especially year 2006)

Bad clutch

Water pump broken, leaking

Fuel hose leaking

Gearchangelink system broken

Generator problems

Engine alternatives in ”The Triplets” (Toyota Aygo, Citroen C1 and Peugeot 107)

2011-12-18T07:07:00.000+01:00

Two engines has been available to choose between, however I not sure the Toyota is available in diesel anymore..? Inputs is appreciated.

4 cylinder 1.4 liter diesel engine: 2WZTV engine, (PSA developed)
1 liter (996 cc), 3 cylinder petrol engine: 1KR-FE engine

My own interest is in the petrol version, so here goes:

The engine is assembled in Poland or Japan (according to wiki)

The engine comes from Toyota, but is designed by Daihatsu. The engine has been chosen “International Engine of the Year” 2007-2010 in the sub category below 1 liter engines.

The engine uses a Timing chain, so you won’t have to replace a belt. The chain will probably last many years before starting to get noise and will need to be replaced. The engine block is made of aluminum and uses Double Overhead Cam (DOHC). The fuel injection system is “multi-point”.

It has VVT-i technology and has 4 valves per cylinder (twelve in total). It produces 50 kW, which equals 50*1,36=68 Swedish Horse powers (hkr). It doesn’t produce mush carbon dioxide footprint either. Here in Sweden it is a “environment friendly car” and the road tax is therefore low on this type of car.

The engine is used in the following cars:

Daihatsu Sirion

Toyota Aygo

Citroën C1

Peugeot 107

Toyota Yaris (1 liter version, called Vitz in some parts of the world)

Toyota IQ

Subary Justy (2008-)

The engine is really small and weights only about 69 kg. Some Internet pages say 67 kg. Perhaps this number is without accessories.

First post - About the site..

2011-12-18T06:52:00.000+01:00

This site will gather information regarding the three city models Toyota Aygo, Citroen C1 and Peugeot 107 (next model will be called 108, released 2012).

I think these car are interesting and fun little cars, and I like the concept of different cars with the same base plate and engine. I like the simple construction and that the cars are cheap to run and environmentally friendly. I also think the most problems have been sorted out now. The site will cover mostly the current models released in 2005.

I will try to keep the site updated, but some periods I may not post so frequently. I you have some interesting information you think I am interested in, don´t hesitate to contact me.

Excuse me for the English language, it is not my mother tongue.. I just thought more people would be interested in reading the information, therefore it is in English, instead of Swedish.
