We remember when the Audi S5 was initially released back in 07', it came sporting the 4.2L V8 producing 354hp.
Then came the 3.0L V6 that was supercharged. Made a little less, but still a decent 333hp.
Now... The S5 has been debuted sporting a 3.0L Single Turbo V6 producing an impressive 354 hp and 369 ft. lb. of torque. That's very close to what the 4.2L did, except this time, they've cut down 2 cylinders.
0-100 km/h times are approximately 4.7 seconds which is respectable. Another key point to look at is the fuel efficiency. The new Audi S5 consumes just around 7.3L per 100km. Which equates to approx 32.2 mpg.
