The Veyron

Gtrsnax · 04-28-2008, 08:47 AM

Over the last few days I've become obsessed with this gift from the heavens. I'm totally blown away at it's engineering and looks and capabilities. Sure, there are other vehicles that have their own thing, but I'm just totally in love with this one.

Bugatti Veyron

The Veyron 16.4 (known as the EB 16/4 Veyron in concept stages) is the most powerful, most expensive, and fastest street-legal production car in the world, with a proven top speed of over 400 km/h. It reached full production in September 2005.

The car is built by Volkswagen AG subsidiary, Bugatti Automobiles SAS, and is sold under the legendary Bugatti marque. It is named for famed Bugatti racing driver, Pierre Veyron who won the 24 hours of Le Mans in 1939.

Specifications

The Veyron features a W16 engine—16 cylinders in 4 banks of 4 cylinders, or the equivalent of two narrow-angle V8 engines mated in a vee configuration.

Each cylinder has 4 valves, for a total of 64, but the narrow V8 configuration allows two camshafts to drive two banks of cylinders so only 4 camshafts are needed. The engine is fed by four turbochargers, and it displaces 8.0 L (7,993 cm³/488 in³) with a square 86 by 86 mm bore and stroke.

Putting this power to the ground is a dual-clutch DSG computer-controlled manual transmission with 7 gear ratios via shifter paddles behind the steering wheel. Or it can be driven by full automatic transmission. The Veyron also features full-time all wheel drive, necessary given the output of the engine.

It uses special Michelin PAX System run-flat tires, which had to be designed specifically for the Veyron, and which are capable of running at 402.3 km/h (253 mph).

The car's wheelbase is 2700 mm (106.3 in). Overall length is 4466 mm (175.8 in). It measures 1998 mm (78.7 in) wide and 1206 mm (47.5 in) tall. Curb weight is expected to reach 4300 lb (1950 kg) with a power to weight ratio of 513.3 hp per ton (metric) or 4.36 lb/hp (SAE). The Bugatti Veyron has a total of 10 radiators.

Performance
The W16 produces 1001 metric horsepower, equivalent to 987 SAE net horsepower or 736 kW. This easily makes it the most powerful production road-car engine in history. Torque is 1250 N·m (922 ft·lbf). According to Volkswagen, the final production Veyron engine produces between 1020 and 1040 metric horsepower (1006 to 1026 SAE net hp), so the car will be advertised as producing "1001 horsepower" in both the US and European markets. Top speed was initially promised to be 252 mph (406 km/h), but test versions were unstable at that speed, forcing a redesign of the aerodynamics.

In May, 2005, a prototype Veyron tested at a Volkswagen track near Wolfsburg, Germany, and recorded a top speed of 248.5 mph (400 km/h)( electronically limited). In October, 2005, Car and Driver magazine's editor Csaba Csere test drove the final production version of the Veyron for the November 2005 issue. This test, at Volkswagen's Ehra-Liessen test track, reached a top speed of 253 mph (407 km/h).

The Veyron is the quickest production car to reach 100 km/h (62 mph) with an estimated time of 2.5 seconds. It also reaches 200 and 300 km/h (124 and 186 mph) in 7.3 and 16.7 seconds respectively. It should also be noted that the Veyron's 0-200mph time is quicker than the McLaren F1's 120-200mph time. This makes the Veyron the quickest-accelerating production vehicle in history.

It also consumes more fuel than any other producton car, using 40.4 L/100 km (5.82 mpg) in city driving and 24.1 L/100 km (10 mpg) in combined cycle. At full-throttle, it uses more than 180 L/100 km (2.1 mpg) - at full throttle, the Veyron would empty its 100 litre fuel tank in just 12.5 minutes. The car's everyday top speed is listed at 234 m.p.h. When the car reaches 137 mph, hydraulics lower the car until it has a ground clearance of about 3 1/2 inches. At the same time, the wing and spoiler deploy. This is the "handling" mode, in which the wing helps provide 770 pounds of downforce, holding the car to the road.

The driver must, using the key, toggle the lock to the left of his seat in order to use the maximum speed of 253 miles per hour. The key functions only when the vehicle is at a stop when a checklist then establishes whether the car - and its driver - are ready to enable 'top speed' mode. If all systems are go, the rear spoiler retracts, the front air diffusers close and the ground clearance, normally 4.9 inches, drops to 2.6 inches.

The Veyron uses unique cross-drilled and turbine vented carbon rotors for braking that draw in cooling air. Each caliper has eight titanium pistons. Bugatti claims maximum deceleration of 1.3 g on road tires.

Prototypes have been subjected to repeated 1.0 g braking from 194 to 50 mph without fade. With the car's fearsome acceleration from 50 to 194 mph, that test can be performed every 22 seconds. At speeds above 124 mph, the rear wing also acts as an airbrake, snapping to a 70-degree angle in 0.4 seconds once brakes are applied, providing up to 0.6 g of deceleration.

Bugatti claims the Veyron will brake from 252 mph to a standstill in less than 10 seconds. The braking is also so evenly applied that the car will not deviate from a straight path if the driver lets go of the steering wheel, even with the brakes fully applied starting from close to top speed.

dude that car is so sick... always have wanted to see one up close

Have yhall seen the Jeremy Clarkson Veyron test on Top Gear? He absolutely was blown away by it. Remarkable car. The next car to top that will have to be able to fly.

That is Jeremy May.

That W style engine sounds friggin sweeet!!!

GTsetGO · 04-30-2008, 01:27 PM

yeah, that car is pure sex on wheels.

That is a badass car but I think they could have accomplished the same thing with a V8 or a V12 at most with TT. Quad turbos seems overly complicated.
