Bugatti Chiron

2025 BUGATTI CHIRON SUPER SPORT "LE DIAMANT NOIR" — EUROPEAN SPECIFICATION

ENGINE AND DRIVETRAIN

The Chiron Super Sport uses Bugatti's quad-turbocharged 8.0-litre W16, a mid-mounted sixteen-cylinder of 7,993 cc formed from two narrow-angle V8 banks on a common crankshaft, fed by four turbochargers and direct petrol injection. For the Super Sport the engine is uprated to 1,600 PS (1,578 bhp / 1,176 kW), 100 PS above the standard Chiron, with 1,600 Nm (1,180 lb-ft) held across a broad plateau. Larger turbochargers, revised internals and a raised rev limit carry power to the top of the range. Drive reaches all four wheels through a seven-speed dual-clutch transmission with paddle shift and Bugatti's permanent all-wheel-drive system. The Super Sport accelerates from 0-100 km/h in 2.4 seconds, passes 300 km/h in just over 12 seconds, and is electronically limited to 440 km/h (273 mph). This is the final model line to use the W16 engine.

CHASSIS, STEERING AND BRAKES

The chassis is redeveloped for high-speed stability and ride comfort, with a rear-axle spring rate approximately 7 percent stiffer than the standard Chiron's, revised adaptive damper tuning and more precise steering. Steering is electromechanical rack and pinion with a variable ratio. Braking is by carbon-ceramic ventilated discs, 420 mm front and 400 mm rear, gripped by monobloc calipers of asymmetric design — eight-piston at the front, six-piston at the rear — with dedicated heat-shield ducting to aid disc cooling. Tyres are Michelin Pilot Sport Cup 2, 285/30 R20 front and 355/25 R21 rear.

DIMENSIONS AND CAPACITIES

Length 4,733 mm, width 2,038 mm, height 1,212 mm, wheelbase 2,711 mm. Fuel tank 100 litres. Kerb weight approximately 1,995 kg. Seating is for two. The Super Sport's 'long-tail' rear bodywork extends the car roughly 25 cm beyond the standard Chiron to reduce drag at speed.

AERODYNAMICS AND BODY

The defining Super Sport feature is the lengthened long-tail tail section, working with air curtains and modified front wheel arches to manage airflow and downforce. The rear wing is carbon fibre with a powered deployment mechanism. Nine exhaust outlets and a widened rear diffuser sit under a carbon-fibre engine cover. The full body structure is carbon fibre over a carbon monocoque.
