The Bugatti 18/3 Chiron premiered at the
Frankfurt Motor Show in September 1999.
Design The design of the Chiron was entrusted to
Fabrizio Giugiaro of
Italdesign with input from Hartmut Warkuß from the
Volkswagen design centre in Wolfsburg. Airflow management and aerodynamics were key considerations in the exterior design. Below the traditional horseshoe radiator grille, a large opening provides enough air to the radiators of the 6.3-litre engine; much of this air is extracted though vents located forward of the front wheel openings. A similar system is used on the side of the car to cool the rear brakes. At the rear a
diffuser was integrated in the rear bumper. A retractable
rear wing deploys at high speeds, much like on the EB 110. The 20-inch eight-spoke wheels resemble the cast aluminium wheels first found on Louis Chiron's
Type 35B. The body work was made from
carbon fibre. Lighting on both ends of the car was cutting edge at its time, including triple
Xenon headlights and elongated turn signals at the rear which also served as the taillights of the car, two double exhaust pipes were visible through a large air extractor at the rear which also served as the underbody spoiler. Inside, the cabin is upholstered in Blu Pacifico and Sabbia leather with aluminium accents. A removable watch is also present on the passenger's side. Important design elements such as the classic horseshoe grille, inset front lights, converging front hood and an exposed intake plenum would eventually be integrated into the production
Veyron EB 16.4.
Engine and chassis |left In order to construct a fully working prototype, Bugatti sourced the chassis and
four-wheel drive system from the
Lamborghini Diablo VT. The 18/3 Chiron uses the same
Volkswagen-designed
W18 engine that debuted on the 1998 EB 118 and the 1999 EB 218 concept cars. As on the other two cars, the Chiron's W18 has a power output of and of torque. The 18/3 Chiron's W18 engine is composed of three banks of six cylinders with a sixty-degree offset between each cylinder bank. In contrast, the
W16 engine in the 2005
Veyron EB 16.4 features a four-bank configuration of four cylinders each, totalling sixteen cylinders. ==References==
