Record breaking Bugatti Chiron with additively manufactured exhaust components

November 20, 2019

APWORKS GmbH has revealed that the recent record-breaking Bugatti Chiron was equipped with additively manufactured titanium exhaust finishers. The car is the first hyper sports car to break the 300 mph barrier (483 km/h), a world record that was set at the beginning of August in Germany.

The pair of exhaust finishers are part of the modified longer tail section, and are designed to push the exhaust emissions further from the rear end of the car to reduce turbulence and improve steering behaviour at high speeds. The design freedom offered by Additive Manufacturing enabled optimised exhaust aerodynamics resulting in increased downforce and enhanced high speed handling of the car.

Titanium is said to be best suited to this application as it combines high strength, heat resistance and low weight. In addition to the aerodynamic benefits, the low mass of the parts also contributes to the exceptional acceleration of the car.

Le Mans winner and Bugatti test driver Andy Wallace reached the top speed of exactly 490.484 km/h (304.773 mph) on August 2, 2019 on the test track at Ehra-Lessien in Lower Saxony.

“Congratulations to Bugatti on the world record. We from APWORKS are proud to be part of this amazing project, having produced the innovative exhaust finishers. The pair of finishers impress by the combination of lightweight, high performance material and optimized emission flow. A functional styling that exceeds limits and enables incredible performance.” says Joachim Zettler Managing Director of APWORKS.

The exhaust finisher can be seen during formnext 2019 at the APWORKS booth, hall 11.1 C71.
