Ferdinand Piëch, the current chairman of Volkswagen’s Supervisory Board, started out at the company at Audi. He saw that there was a need for an engine that was larger than the current four cylinder units, but he also believed six cylinders was more than enough. To solve this problem, he resurrected a one of his own designs. In 1976 Audi got its first five-cylinder engine in the redesigned 5000 model. But what it’s most famous for is being the engine of choice for Audi’s rally-winning Quattro cars of the 80s.
Ever since then, there has always been a five-cylinder unit in use somewhere in the Volkswagen Group, but Audi has abandoned the engines for turbo fours and V6 over a decade ago. But now it’s back at Audi for the TT RS.
Audi’s hottest TT model will likely use a turbocharged version of the 2.5-liter five-cylinder unit found in the Golf/Rabbit/Jetta, with which the TT already shares many components. The TT RS is expected to make 330 - 340 hp. By comparison, the next model downline, the TTS, makes 265 hp with its 2.0-liter turbo four-cylinder engine. The TT RS should be good for a 0 to 60 time of about 4.5 seconds (0.5 quicker than the TTS.)
All the technical specs as well as body modifications will be confirmed when the TT RS makes its debut in March at the Geneva Motor Show.
