Absolute horsepower numbers only paint part of the picture when it comes to how quickly a vehicle can accelerate. Extra weight hinders straight-line performance, which is why auto experts often refer to the weight-to-power ratio for true apples-to-apples comparisons. This model's ratio of 10.92 lbs/HP is 30% better than the segment average of 15.61 (a lower number is better), making this one of the quickest sedans in its class. According to Audi, it accelerates from 0-60 in 4.9 seconds, and given the chance, top out at 155 miles per hour.

This model is equipped with a turbocharged 3L V6 engine, sending power to the wheels.

This car aligns with gas mileage expectations for a compact luxury sedan, at an overall 23 MPG (evenly weighted average of 18 city / 28 highway).

In city driving, S4 owners can expect to cover about 304 miles on the 16.9 gallon tank, 38 miles less than the class average. On the highway, a maximum range of 473 miles is 20 less than that of rival sedans.
