Answer 2

(from Bugatti Press Release)  The trials of the fastest road sports car in the world have been successfully completed. One of the most ambitious projects in automobile history is entering its production phase. The first Bugatti Veyron 16.4 cars, built mainly by hand, are already being completed and will be delivered to customers this year.

The sports car, capable of more than 400 km/h, is driven by a 16-cylinder mid-engine, that at 710 mm

long is no larger than a conventional V12 unit, and due to its lightweight construction weighs only

about 400 kilos. Its compact dimensions are due to the unique arrangement of its cylinder banks in

a W configuration. Two VR8 blocks, each with a fifteen degree bank angle, are joined in the crankcase

to form one engine. Both eight cylinders are set at an angle of ninety degrees to each other and are

aspirated by a total of four exhaust gas turbochargers. The engine delivers 1001 HP at 6,000 r.p.m.

and provides a maximum torque of 1250 Newtonmetres at between 2,200 and 5,500 r.p.m.
