420 HP Audi RS4 V6 Bi Turbo Revs and Accelerations

I ve filmed this beautiful black on black Audi RS4 Avant 2. 7 V6 BiTurbo Quattro, specially prepared to produce 420HP, 40 more than the stock one. Thanks to the Supersprint exhaust system, the car sounds also really good. Here you can see it starting up, revving and doing some fast accelerations on the track If you like this video please rate and comment Like my Facebook page: Subscribe to my second car channel:
