In the sports sedan tug-of-war among Audi, BMW and Mercedes-Benz, the A4 now prevails over its peers. Sports sedans often fall short of expectations, being neither sporty nor luxurious, or prove unreliable. The A4 gets all of these things right, which is why it jumps to the top of this class in our rankings.
The familiar 2.0-liter turbocharged four-cylinder engine remains under the A4’s hood, and continues to impress, with prompt throttle response, ample low-end power, and a free-revving nature. It feels smoother than most turbo fours and gives a nice growl under hard acceleration. If you must have the V6, you may want to consider the 349-hp S4.
