The Volkswagen-designed 8.0-liter W16 is based on the unit found in the Veyron and was updated for the Chiron to produce 1,479 horsepower. The engine utilizes a single crankshaft shared by two cylinder banks set at a 90° angle, with each bank consisting of eight cylinders set in a 15° V configuration. Each bank is topped by a single cylinder head with dual overhead camshafts operating four valves per cylinder. Four turbochargers push air through two intercoolers into twin intake manifolds, while the duplex fuel injection system utilizes 32 injectors. Bugatti claims a 0-62-mph time of 2.4 seconds for the Chiron as well as a top speed of 261 mph. Power is sent to all four wheels through a Ricardo seven-speed dual-clutch automatic transmission, a front Borg-Warner torque transfer differential, and a rear axle with a transverse differential lock via Haldex electronic control. Both the engine and gearbox feature dry-sump lubrication with individual oil coolers that are among a total of 10 heat exchangers, the other eight of which handle the engine coolant, intercoolers, rear differential, and air-conditioning system.
The multi-function flat-bottom steering wheel features carbon-fiber and Italian Red leather trim. It fronts polished aluminum paddle shifters and a 300-mph analog speedometer with an inset digital speed readout flanked by two digital screens.
The digital odometer shows 1,900 miles.
