The Urus’ 4.0 L twin-turbocharged V8 is actually a modified version of Audi’s 4.0 L V8 that can be found in both the Porsche Cayenne / Panamera as well as some of the Audi S / RS models, the A8, the Bentley Continental V8 and the Flying Spur V8. Unlike the version found in those vehicles, this engine has been heavily modified, boosted by 99 hp and 59 lb-ft of torque over Cayenne Turbo.
