The Audi S5 may be the prettiest car on this list, but that doesn’t make its engine any less potent. The S5 features Audi’s 4.2-liter V8, which puts out 354-hp to all four wheels. All this comes with the S5’s handsome looks, and impressive luxury amenities. All that power helps get the S5 to 60 mph in 4.9 seconds. If you’re planning on getting a S5, you should be advised that the V8 engine is soon to be replaced with a supercharged V6, so make your move before those extra cylinders disappear.
