What does it take to get heavy, luxurious supercar to 252 mph and back to zero?

1 TRANSMISSION

The seven-speed sequential manual transmission does not a clutch pedal. Instead, paddles in front of the steering wheel control dual automatic clutches. One is always engaged; the other waits, attached to next gear. When you shift, the new gear engages nearly instantaneously, with no pause in power flow.

2. INTERIOR

Bugatti expects one of the most requested option to be pair of 1-carat diamonds, each cut into an unusual nut symbolic 16 facets(to represent the number of cylinder). One gem is set in the speedometer, the other in the power meter, which displays how many of the 1,001 horses are being hamessed.

3. TIRES

Special Michelin PAX tires manage the heat of high-speed running and can run flat for 125 miles at up to 50 mph. the rears are record-breaking 14.4 inch wide.

4.SUSPENSION

Suspension is relatively conventional: double wishbones, coil springs,  shock absorbers without electronic controls. But there’s also reputed to be a lifting mechanism to stop the nose from plowing into pavement on steep ramps.

5. BODY

Engineers sculpted the body from hand-laid carbon fiber, through aluminum sub frames carry the suspensions at either end(VW knows how to make these absorb energy in a crash) . the under body is shaped to create a venturi effect, sucking the body to the ground for added downforces.  A spoiler extends up and backwards from the rear of the car at speed, any stays up for a while after the car at speed, and stays up for a while after the car is stopped to let heat exit the engine bay.

6. BRAKES

Ultra-expensive carbon composite, resistant to heat and wear, and provide eye-poping deceleration. When breaking hard, the car deploys a second spoiler to provide airbraking and additional downforce. The spoiler cuts stoping distance by 65 feet from 180 mph.
