The TFSI engine is a joy to drive, on, or off the track. It sings, like an old song with melody, each gear a note, waiting to explode into a crescendo.

Stephen Reil is the head of the Audi Quattro division, with the pleasurable duty of overseeing thedevelopment of Audis quattro GmbH of the RS platform and the racing program.

Quattro is what Audi calls their all-wheel drive, but it’s more than an all-wheel drive. Reil can make a business case for each car that becomes part of the RS program.

The 2012 Audi TT RS, 2.5 liter turbocharged, in-line five-cylinder, spark-ignition engine with TFSI direct injection makes 360 horsepower and 343 lb-ft of torque. A 0-60 of 4.1 seconds is only the beginning of the joy you can feel when you drive this car, or, or off, the track. The six-speed manual is the only transmission available in the United States.

The two door coupe starts at $56,850. Add $875 shipping and handling. It is worth every penny.
