Earlier today, Alfa Romeo revealed the production version of the 4C (2014), which is going to have its world debut at the 2013 Geneva auto show next month. The new Alfa Romeo 4C (2014) measure less than 4 meters in length, 200 cm in width, and 118 in height and it has a 2.4 meters wheelbase. To power the 4C, Alfa Romeo uses the 4-cylinder 1750 turbocharged petrol engine with direct injection. Alfa Romeo did not disclose the output of this new engine, however, they do mention that the 4C has a power-to-weight ratio of 4 kg/hp. Its engine is mated to a TCT automatic twin dry clutch transmission with steering wheel mounted paddle shifters. The 0-62 mph (0-100 km/h) acceleration time of the Alfa 4C and its top speed will be announced at a later date. The Alfa 4C is rear-wheel-drive, obviously, and it’s made from carbon fiber and aluminum in order to keep its weight to a minimum.

The exterior design of the Alfa 4C is inspired by the 33 Stradale, but follows the general design lines of the much newer 8C. Alfa Romeo spent a lot of time wind the wind tunnel when developing the aerodynamics of the 4C. As a result, the car comes with a negative Cz (downforce coefficient).

As you’re expecting, the interior of the 4C is full of carbon fiber. The car offers four different setups for the engine, and suspension systems: Dynamic, Natural, All Weather and Race.

The price will be announced at a later date.

Earlier today, Chevrolet announced the world debut of the 2014 Corvette Stingray Convertible. It will be revealed at the 2013 Geneva Motor Show at the beginning of March. Chevrolet says about the convertible version of the new Corvette Stingray (2014) that it’s going to offer the same balance, design and performance as the coupe version. Usually, convertible versions are a bit heavier than the coupes, so we’re not really sure if the open-top 2014 Corvette Stingray will be able to match its hard-top sibling’s performance and balance. As you can imagine, Chevy did not disclose any details regarding the 2014 Corvette convertible.

However, we can make a few speculations. For starters, we’re pretty sure that the new Corvette convertible (2014) is going to have the same engine as the coupe. This means it’s going to hide under its hood a 6.2-liter V8 engine that will send 450 hp and 610 Nm of torque to the rear wheels. In terms of performance, it will probably get to 62 mph (100 km/h) in around 4 seconds.

The 2013 Bentley Continental GT Speed is based on the latest version of the model, which has received a lower and stiffer suspension and a more powerful engine. The 2013 Conti GT Speed hides under its hood a 6.0-litre, 48-valve, four-cam, twin turbocharged W12 monster of an engine, which spits out 625 PS (616 bhp/460 kW) at 6000 rpm and 800 Nm of torque. Despite the 2013 Continental GT Speed’s size and weight, this engine is able to take it from zero to 60 mph in just 4.0 seconds (0-100 km/h in 4.2 seconds). Bentley’s latest GT Speed (2013) is rated with a top speed of 205 mph (329 km/h). As expected, the 2013 GT Speed gets a close-ratio, ZF eight-speed automatic gearbox. Bentley does not disclose any efficiency figures regarding the 2013 Conti GT Speed, however, they do mention they managed to reduce its CO2 emissions by 12%.

Some of distinctive design details of the 2013 Bentley Continental GT Speed include its 21-inch alloys, its dark front grille and lower air intakes, and its exhaust tailpipes. For the interior of the 2013 Continental GT Speed, Bentley is offering the Mulliner Driving Specification as standard, as well as other styling part.

Hennessey Performance has announced their range of upgrades for the Chevrolet Camaro ZL1. Hennessey’s Camaro ZL1 is available in four versions: HPE650, developing 658 bhp at 6,200 rpm, HPE700 with 707 bhp at 6,300 rpm, and HPE800 with 800 bhp at 6,200 rpm.

The top of the range Hennessey Camaro ZL1 is the HPE1000, which outputs no less than 1,021 bhp at 6,400 rpm. Take that Veyron! The HPE1000 is powered by a 427 cid LSX engine, featuring forged crank, pistons and rods, as well as other modifications. The Hennessey Chevrolet Camaro ZL1 HPE1000 also features an upgraded fuel system, twin ball bearing turbochargers, dual wastegates and an electronic boost controller. An air-to-air intercooler and a high-flow K&N air filter are also required. The standard transmission of the Chevrolet Camaro ZL1 can not take the 1,000 hp of the HPE1000, so Hennessey has to replace the original clutch with a Centerforce Dual Friction one.

Apart from the incredible power increase, Hennessey’s HPE1000 package for the ZL1 also includes various badges and serial-numbered plaques on the dashboard and engine. The HPE1000 kit for the Chevy Camaro ZL1 comes with professional installation, engine calibration, and a 1 Year / 12,000 Mile Limited Warranty.

Hennessey did not disclose the price of their HPE1000 upgrade for the Chevrolet Camaro ZL1.

Earlier this week, the new generation 2013 Aston Martin Vanquish was unveiled.

Aston’s 2013 Vanquish borrows several design cues from the carmaker’s flagship model, the One-77 supercar, which include the LED taillights. Another design particularity is the 2013 Vanquish’s Aero Duct on the rear boot lid, which is able to reduce lift on the car’s rear axle. To power the 2013 Vanquish, Aston Martin uses a new naturally aspirated 6.0-litre V12 petrol engine, which is mated to a Touchtronic 2 six-speed automatic transmission. The new Vanquish (2013) is rated with an output of 573 PS at 6,750 rpm, 620 Nm of torque at 5,500 rpm. This is more than enough to take it from nought to 62 mph (100 km/h) in 4.1 seconds. The top speed of the new Aston is rated at 183 mph (295 km/h).

The 2013 Aston Martin Vanquish was designed to be Super Grand Tourer, which means it has to be fast, comfortable and elegant. The 2013 Vanquish is going to be available in two seating configurations: 2+2 and 2+0. However, we believe that the 2+2 configuration will not offer too much room for the rear passengers. To assure the comfort of the passengers, Aston Martin equipped the 2013 Vanquish with an independent double wishbone suspension with anti-dive geometry on the front and anti-squat / anti-lift geometry on the rear.

The Adaptive Damping System (ADS) system of the new Vanquish (2013) offers three settings: Normal, Sport and Track.

The equipment list of the 2013 Aston Martin Vanquish includes 1000W Bang & Olufsen BeoSound audio system with 13 speakers, Garmin satellite navigation system, and the connectivity you’ll ever need (iPod/iPhone, USB, Bluetooth and Wi-Fi Hub5). The 2013 Aston Martin Vanquish’s price starts at £189,995 RRP. Aston says it’s going to start delivering it later this year.
