Audi RS5 boosted to 506-hp by Senner Tuning

With 450 horsepower in stock form, the Audi RS5 is certainly no slouch in the power department. That however, hasn't stopped Senner Tuning from extracting a few extra horses from the RS5's 4.2-liter V8 - fifty six extra to be exact. Upgrades of Senner Tuning's 506-hp RS5 include a new performance exhaust, Bilstein coilover suspension, 20" Varianza wheels and a few added touches of carbon fiber.
