Four turbocharged cylinders
There's no doubt that Audi's 2-liter turbocharged direct-injection four-cylinder is an excellent engine, and that is good, because the TFSI 2.0 is the only engine available. Previously, the A4 could be had with a 3.2 V-6 and a torque-vectoring differential. However, the A4 still gets Quattro all-wheel drive and Audi's Drive Select feature as an option, which changes the suspension between comfort and sport modes.
Put the A4 in drive, release the electronic parking brake, and the little car feels eager to go. The engine, producing 211 horsepower and 258 pound-feet of torque, rarely betrays turbo lag, most likely due to some masking by the transmission. The engine easily propels the A4 up to speed, and gives it a good amount of zip for quick lane changes and passing.
With the automatic transmission's eight gears, the A4 can be humming down the freeway at 70 mph, the tachometer needle pointing to a leisurely 1,800rpm. Small engines usually have to work harder at high speeds. The result is 21 mpg city and 29 mpg highway by EPA testing. CNET's car averaged right around 25 mpg through a mix of city, freeway, and mountain driving.
In the city the A4 is an easy driver, comfortable and maneuverable. The transmission never got confused about which gear it should be in and the power steering made for easy turning. And the rearview camera, which comes with the navigation system, proved a nice help when parking. Audi's camera shows trajectory lines and distance markers, making bumper tapping unnecessary.
The transmission has sport and manual shift modes, which led to some fast cornering high jinks on our favorite mountain roads. When we dropped into sport mode, the transmission kept the engine speed high, favoring 3,000rpm to 4,000rpm, but it was not overly aggressive. Manual shifting was not particularly tight, showing typical torque converter softness.
The suspension felt tuned more for comfort, letting the car lean quite a bit in turns, but smoothing over the odd bumps in the road nicely. Although the suspension was not screwed down tightly, the Quattro system helped the cornering performance. The A4 feels very light and nimble, with good balance and a responsive steering rig.
With the advanced technology of the A7, Audi raised our expectations so much that the 3D maps in the 2011 A4's navigation system seemed run-of-the-mill. And we did notice some limitations with the POI database. But it is still a very good navigation system. Add in the Bang & Olufsen audio and Bluetooth phone integration, and you have almost all you could want when it comes to cabin tech.
Audi didn't shoot for the stars with the A4's fuel economy. Other cars of its size push well into the 30 mpg range. But it gets reasonable fuel economy for a premium midsize sedan. The new eight-speed transmission is a nice addition. The Drive Select option would give the car better handling.
