The four-cylinder TFSI engine fulfills its everyday tasks with ease, including domination of the passing lane. There is very little turbo lag and the engine pulls strongly from low rpm. We won’t complain about the numbers: Audi says the A4 Allroad reaches 60 mph in the mid-six-second range and reaches a top speed of more than 140 mph. And the engine even sounds pretty good, with a sporty undertone you rarely find in four-cylinder mills. Still, it wouldn’t be our engine of choice for spirited driving on two-lane roads with lots of shifting and revving at redline. The torque curve drops sharply around 4000 rpm, and beyond that point, the engine reneges on its promise of relentless power from 1500 rpm on up. So it’s no Honda S2000 engine, but it needn’t be in this type of vehicle. The TFSI gives a clear indication of where mainstream gasoline engine technology is headed.
In a way, the 2.0-liter behaves like a modern diesel engine, although with a higher redline. And it doesn’t use much more fuel, either, achieving a claimed 29 mpg in the European cycle—impressive for a height-enhanced, 3600-pound station wagon. Normal drivers won’t have any problem with these torquey, fuel-efficient four-cylinders, which offer the performance of a six-cylinder without the associated penalties to efficiency.
