2016 Audi R8 V10 - Exhaust sound

The V10, which is produced at the engine plant in Hungary, in part by manual assembly, is very compact. Its low mounting position in the car results in a low center of gravity.

The crankshaft is designed as a common pin shaft. The connecting rods of opposing pistons are joined to a common crank pin, which results in alternating firing intervals of 54 and 90 degrees. This rhythm makes a big contribution toward producing a very unique, motorsport-like sound. Two flaps in the exhaust system let the driver choose between a comfort-oriented sound and a sporty sound. The entire sound stage is authentic – including the babbling sound when the foot is taken off the accelerator pedal and a more roaring sound when shifting gears under full load.

The cylinder crankcase of the 5.2 FSI is manufactured in a complex low-pressure die-casting process with a high-tech aluminum alloy that combines low weight and high strength. The cylinder liners are honed from the solid piece by exposing the hard silicon crystals. The bed plate construction of the crankcase gives it maximum rigidity, and gray cast iron bearing brackets reduce heat expansion and thereby improve bearing play. The forged crankshaft and the connecting rods that are made of forged steel combine high strength and low weight, and the pistons are forged from an aluminum alloy.
