Displacement is out. Supercharging is in. At least that’s the direction some automakers are taking. Case in point, the Audi S5.
Our long-term coupe is a 2009 model with a 4.2-liter V8. It makes all sorts of great noises and pulls quite nicely, too. This year, however, Audi is beginning a transition to a 3.0-liter, supercharged V6 for the S5. The engine may be over a liter down in displacement, but the supercharger helps it make nearly as much power as the V8 while delivering considerably better fuel mileage. Weighs less, too.
So how much of a difference does the change make?
