Compare the2026 Bugatti Tourbillon VS 2026 Porsche 911

For enhanced safety, the front seat shoulder belts of the Bugatti Tourbillon are height-adjustable to accommodate a wide variety of driver and passenger heights. A better fit can prevent injuries and the increased comfort also encourages passengers to buckle up. The Porsche 911 doesn’t offer height-adjustable seat belts.

The Bugatti Tourbillon has standard driver and front passenger side knee airbags mounted low on the dashboard. These airbags help prevent the driver and front passenger from sliding under their seatbelts or the main frontal airbags; this keeps them better positioned during a collision for maximum protection. Knee airbags also help keep the legs from striking the dashboard, preventing knee and leg injuries in the case of a serious frontal collision. The 911 doesn’t offer knee airbags.

To provide maximum traction and stability on all roads, Full-Time Four-Wheel Drive is standard on the Tourbillon. But it costs extra on the 911.

Both the Tourbillon and the 911 have standard driver and passenger frontal airbags, front seatbelt pretensioners, four-wheel antilock brakes, traction control, electronic stability systems to prevent skidding and rearview cameras.

The Tourbillon comes with a full 4-year/unlimited-mile basic warranty, which covers the entire car. The 911’s 4-year/50,000-mile basic warranty expires sooner.

Bugatti pays for scheduled maintenance on the Tourbillon for 3 years and unlimited miles longer than Porsche pays for maintenance for the 911 (4/unlimited vs. 1/10,000).

The Tourbillon’s 8.3 DOHC V16 hybrid produces 1387 more horsepower (1775 vs. 388) and 702 lbs.-ft. more torque (1033 vs. 331) than the 911’s standard 3.0 turbo 6-cylinder. The Tourbillon’s 8.3 DOHC V16 hybrid produces 1302 more horsepower (1775 vs. 473) and 643 lbs.-ft. more torque (1033 vs. 390) than the 911 S’ standard 3.0 turbo 6-cylinder. The Tourbillon’s 8.3 DOHC V16 hybrid produces 1273 more horsepower (1775 vs. 502) and 702 lbs.-ft. more torque (1033 vs. 331) than the 911 GT3’s standard 4.0 DOHC 6-cylinder. The Tourbillon’s 8.3 DOHC V16 hybrid produces 1074 more horsepower (1775 vs. 701) and 443 lbs.-ft. more torque (1033 vs. 590) than the 911 Turbo S’ standard 3.6 turbo 6-cylinder hybrid.

The Tourbillon can travel with zero emissions for 37 miles. The 911 can’t move without running its internal combustion engine.

The Tourbillon has a standard cap-less fueling system. The fuel filler is automatically opened when the fuel nozzle is inserted and automatically closed when it’s removed. This eliminates the need to unscrew and replace the cap and it reduces fuel evaporation, which causes pollution. The 911 doesn’t offer a cap-less fueling system.

The Tourbillon has standard air brakes, which adjust the rear spoiler automatically during high-speed braking in order to shorten stopping distances. The 911 doesn’t offer air brakes.

For better traction, the Tourbillon has larger tires than the 911 (F:285/35R20 & R:345/30R21 vs. F:235/40R19 & R:295/35R20). The Tourbillon’s tires are larger than the largest tires available on the 911 (F:285/35R20 & R:345/30R21 vs. F:255/35R20 & R:325/30R21).

The Tourbillon’s 285/35R20 front and 345/30R21 rear tires provide better handling because they have a lower 35 series front and 30 series rear profile (height to width ratio) that provides a stiffer sidewall than the 911’s standard 40 series front and 35 series rear tires.

For better ride, handling and brake cooling the Tourbillon has standard 20-inch front and 21-inch rear wheels. Smaller 19-inch front and 20-inch rear wheels are standard on the 911.

For a smoother ride and more stable handling, the Tourbillon’s wheelbase is 11.3 inches longer than on the 911 (107.8 inches vs. 96.5 inches).
