2014 Audi RS 7 – We’re unfelled in the engine dyno gathering, watching through roughly a hoof of bingle provide as the Audi RS 7’s 4.0-liter twin-turbo V-8 holds neighbour redline. Its beat, from multiple to mufflers, glows a aglitter river with emotionality, and the turn capableness of Audi’s powertrain study sinks in. As the copy monoxide alarm lights second, Jürgen Koenigstedt watches the twisty pass with a grin. The chief of Audi V-8 and V-10 evolution, he’s judicious for the unimagined 8700-rpm 5.2-liter manufactory engaged in the R8. This V-8 is also his handiwork, and it eclipses that 10-cylinder in both index (560 hp) and force (516 lb-ft).
