Powering the Brilliant Red 2009 Audi A4 2.0 T quattro Tiptronic through our battery of instrumented flogging was a heavily massaged version of Audi’s 2.0L mill that’s become a staple of the Volkswagen Group parts bin. The engine has undergone numerous incremental improvements, the biggest of which being the addition of Audi’s valvelift system.
Audi’s powertrain brains developed the valvelift system in order to allow for variable control of the exhaust valves, improving the engine’s charge cycle, according to the automaker.

The updated four-banger’s added power, in conjunction with the effective six-speed automatic, helps moves the 2009 A4 up the time sheets. Our A4 tester boogied from 0-to-60 in 6.5 sec, more than a sec faster than a 2008 A4 2.0L, on to a quarter-mile sprint in 15 sec flat at 98 mph.
The new A4’s minimal weight gain is even more impressive when you get out the tape measure. It’s roughly 2.3 in. wider and 4.6 in. longer than the car it replaces, and at 110.6 in., its wheelbase is more than 6 in. longer, helping to improve the car’s weight distribution to 55/45% front to rear. Audi claims the increased wheelbase, along with a quattro system that’s biased 40% front, 60% rear, aids the new car’s overall handling prowess.
