Self Study Program 923603 – The 5.2L V10 FSI Engine

VAG SSP 923603. For the first time in its history, Audi is offering a 10-cylinder engine for production based vehicles. This 5.2 liter engine will be used in both the Audi S6 and S8 models.

A 10-cylinder engine is synonymous with dynamic power as seen in the Gallardo engine built by the Italian super sports car brand Lamborghini, a subsidiary of Audi. The combination of 10 cylinders and FSI technology gives Audi a unique position in the market.

The 5.2L engine belongs to the next generation of Audi V engines. It features a 90° V angle with 90 mm between cylinder centers. Similar in design to the Lamborghini V10 engine, the Audi version differs in that the bore, stroke, and displacement have all been increased.

A 5-liter V8 engine would have been more compact, but the pistons and connecting rods would also need to be heavier, thereby limiting the engine. It would not rev as freely as a V10 and would diminish the sporty characteristics.
