How does the engine of the Audi R8 differ from the Audi RS3?

I am looking into purchasing either an Audi R8 or Audi RS3 and am curious about the differences in the engine design. Any insights?

The Audi R8 features a V10 engine, while the Audi RS3 has a turbocharged inline-five engine. The V10 engine offers a higher power output and a more refined driving experience. However, the RS3's turbocharged engine provides a more immediate boost of power and can be more fuel efficient in certain driving situations. It ultimately comes down to personal preference and driving style.
