In the 1980s, an iconic legend was born as the world fell in love with Audi's 5-cyliner engine's unmistakable and intoxicating growl. To the Audi enthusiast, the light-weight, compact 5-cylinder engine represented the hallmark of Audi's technical prowess and ability to emotionally captivate an audience with a driving experience unlike any other in its time. Audi's announcement of the return of its 5-cylinder roots via the 2.5 TFSI sent shockwaves across the community and resonated deeply within the hearts and minds of APR's staff. With this creation, Audi spoke directly to every enthusiast and gave APR the unique opportunity to write into Audi's 5-cylinder history books with modern day engineering expertise.
APR's technical reach has grown enormously since opening in the 1990s and currently represents a force of unmatched performance without compromise within the performance enhancement sector for Audi vehicles. The APR Stage III 2.5 TFSI Turbocharger System is a culmination of roughly two years worth of engineering research, development and motorsport testing unheard of in the market today. With brutal testing on multiple continents, including wins in the prestigious German Tuner GP at the Hockeheim ring, the APR Stage III Turbocharger System is the pinnacle of Audi's German engineering enhanced by APR's American ingenuity.
The APR Stage III Turbocharger System is a turnkey solution designed to expand on the TT RS's already stellar performance by increasing peak horsepower to roughly double that of the European model. Sitting at 665 horsepower and over 560 ft-lbs of torque on high octane fuel, the vehicle's performance is transformed to that of a modern day equivalent of Audi's motorsport 5-cylinder engines of yesteryear. APR's advanced knowledge of engine management combined with an uncompromising selection of premium materials, access to the latest engineering equipment and techniques, as well as a highly educated and capable staff of engineers, resulted in a turbocharger system capable of delivering a truly exhilarating and fulfilling driving experience.
