### Power

According to Volkswagen (and approved by TÜV Süddeutschland)
the final production Veyron engine produces 736 kW (987 hp) which is
equivalent to 1001 PS (metric horsepower) and 922 ft·lbf (1,250 N·m)
torque.^{[2]} However, the car is advertised as producing "1001 horsepower" in both the US and European markets.

### Top Speed

Top speed was initially promised to be 407 km/h (253 mph) 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 recorded an electronically limited top speed of 400 km/h (249 mph). 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-Lessien test track, reached a top speed of 407.5 km/h (253.2 mph). The top speed was verified once again by James May on Top Gear,
again at Volkswagen's private test track, when the car hit 407.9 km/h
(253 mph), which equated to precisely one-third of supersonic speed at
sea level. When getting close to the top speed during the test he said
that "the tires will only last for about fifteen minutes, but it's okay
because the fuel runs out in twelve minutes." He also gave an
indication of the power requirements, at 249 km/h (155 mph) the Veyron
was using approximately 270 bhp (201 kW), but to get to its rated
407 km/h (253 mph) top speed required far more from the engine.

Aerodynamic friction or drag
is proportional to the square of the speed; for example doubling speed
quadruples drag. Work is a product of force applied over a distance
travelled. Comparing a vehicle travelling at 100 mph (160 km/h) with
one travelling at 200 mph (320 km/h), over a given period of time (e.g.
1 second), the faster vehicle must overcome 4 times the aerodynamic
drag, and travel twice the distance of the slower one. Thus it does 8
times the work of the slower vehicle in that period of time. As power
is work done / time taken it follows that the faster vehicle,
travelling at twice the speed requires 8 times the power of the slower
one. German inspection officials recorded an average top speed of
408.47 km/h (253.8 mph)^{[3]} during test sessions on the Ehra Lessien test track on April 19, 2005.

The car's everyday top speed is listed at 375 km/h (233 mph). When
the car reaches 220 km/h (137 mph), hydraulics lower the car until it
has a ground clearance of about 8.9 cm (3½ inches). At the same time,
the wing and spoiler deploy. This is the "handling mode", in which the
wing helps provide 3425 newtons (770 pounds) of downforce, holding the car to the road.^{[10]}
The driver must, using a special key (the "Top Speed Key"), toggle the
lock to the left of his seat in order to attain the maximum (average)
speed of 407 km/h (253 mph). 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 12.5 cm (4.9 inches), drops to 6.5 cm (2.6 inches).

### Acceleration

The Veyron is the quickest production car to reach 100 km/h (62 mph) with a proven time of 2.5 seconds^{[citation needed]}. It reaches 60 mph (97 km/h) in approximately 2.46 seconds. This is an average acceleration of 1.18 g.

The forward acceleration in a Veyron may also be strong enough to cause head-up illusion, which gives passengers the impression of driving up a slope, very much like what is commonly experienced in a jet liner that accelerates for take off. This could arguably lead to false perception of stopping distances.

The Veyron reaches 200 and 300 km/h (124 and 186 mph) in 7.4 and 16.7 seconds respectively. And according to the February 2007 issue of Road & Track Magazine, the Veyron accomplished the quarter mile in 10.2 seconds at a speed of 142.9 mph (230.0 km/h). Other tests, however, have the Veyron hitting 150 mph (240 km/h) in 9.8 seconds (see below), so the quarter mile time is actually faster, making the Veyron the most rapidly accelerating production car in history.

### Fuel Consumption

The Veyron consumes more fuel than any other production car, using
40.4 L/100 km (6.99 mpg imp/5.82 mpg US) in city driving and
24.1 L/100 km (11.7 mpg imp/9.76 mpg US) in combined cycle. At full
throttle, it uses more than 115 L/100 km (2.46 mpg imp/2.05 mpg US),
which would empty its 100 L (26 US gal/22 imp gal) fuel tank in just 12
minutes 46 seconds.^{[13]}

### Braking

The Veyron's brakes use unique cross-drilled and turbine-vented carbon rotors which draw in cooling air to reduce fade. The front calipers have eight^{[10]} titanium pistons and the rear calipers have six 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 (312 to 80 km/h) without fade. With the car's
acceleration from 50 to 194 mph (80 to 312 km/h), that test can be
performed every 22 seconds. At speeds above 124 mph (200 km/h), the
rear wing also acts as an airbrake, snapping to a 55-degree angle in 0.4 seconds once brakes are applied, providing 0.68 *g* (4.9 m/s²) of deceleration (equivalent to the stopping power of an ordinary hatchback).^{[10]} Bugatti claims the Veyron will brake from 400 km/h (249 mph) to a standstill in less than 10 seconds.^{[10]}

The Veyron's performance was tested by Top Gear's Richard Hammond in a race against a Eurofighter Typhoon.
