Cosworth 8.3L Naturally Aspirated V16

The Cosworth 8.3-litre naturally aspirated V16 is the centrepiece of the Bugatti Tourbillon, launched in 2024. Developed in partnership between Bugatti and Cosworth — legendary for Formula 1 and IndyCar engineering — it represents the pinnacle of internal combustion engine technology for road-going vehicles. The engine produces 1,000 bhp at 9,000 rpm with a rev ceiling of 9,000 rpm, featuring a flat-plane crankshaft arrangement and individual throttle bodies for each cylinder. Unlike turbocharged predecessors, its power delivery is entirely linear, providing the visceral acoustic and mechanical experience that defines the Tourbillon's character. In the Tourbillon's hybrid powertrain, the V16 is paired with three electric motors (two at the rear axle, one at the front) to deliver a combined system output of 1,800 bhp. The ICE unit acts as the primary performance powerplant, with the electric system providing torque fill and front-axle drive. Manufacturing is carried out at Cosworth's Northampton facility, using advanced CNC machining, precision casting, and racing-grade assembly processes honed over decades of motorsport supply.
