PARIS: Bugatti has detailed the hybrid powertrain of its Tourbillon hypercar in Episode 08 of the ‘A New Era’ series, now streaming on its YouTube channel.
The segment reveals how an 8.3-litre naturally aspirated V16 engine integrates with electric motors to redefine hyper-sports performance.
The powertrain combines a V16 engine, eight-speed double-clutch transmission with torque-vectoring differential and a 250 kW electric motor capable of 24,000 rpm, all weighing just 430 kg – the same mass as the Chiron’s V16 alone.
A front axle unit houses two independent electric motors and inverters, while a 116 kWh T-shaped battery pack — comprising over 1,500 cells with oil cooling — is built into the chassis for added rigidity and optimal weight distribution. The complete system delivers around 579 hp and 1,164 Nm of torque.
Despite its complexity, the Tourbillon is lighter than its predecessor and offers a higher top speed, faster acceleration and increased luggage capacity.
Innovative 3D-printed suspension parts are 45 per cent lighter than earlier designs. The electric motors operate at 800 volts and function as starters, generators and performance boosters, eliminating the need for traditional 12-volt starters and allowing in-drive battery charging.
The hybrid architecture also enables a zero-emissions range of more than 60km.
Engineers emphasise that electric assistance is not a replacement but an enabler for the V16’s high-revving character, providing instantaneous response where the combustion engine cannot.
The result is a compact, low-slung silhouette with trademark short overhangs, accommodating the extended drivetrain without compromise.
Bugatti describes the Tourbillon’s system as a “harmonious synthesis” that marries emotional combustion power with modern electric precision.
