The 2010 Audi RS5 has seen praises from most of the journalistic world with one of the most prominent features being the engine.

The Ingolstadt factory decks the RS5 out with quite a punch and somehow you knew the tuning world would eek that extra bit out of it.
Senner Tuning, a German tuning firm, had their own ideas about how much power the V8 under the bonnet of the RS5 should produce.

Bear in mind that in standard trim the 4.2 liter naturally aspirated V8 pumps out 450 horsepower and 317 lb-ft of torque. In Senner Tuning form, thanks to a new valve-controlled stainless steel exhaust system and some electronic fiddling the 2010 Audi RS5 develops 506 horsepower and 353 lb-ft of torque.
There’s another benefit to the electronic mod, the top speed limiter has been removed, which means that the Audi RS5 can now reach 174 mph. If that’s not enough Senner will hook you up with a new set of tires so you can cruise all the way up to 186 mph.
Naturally, as one interesting comic book hero, with great power comes great responsibility. This is why Senner Tuning will not only beef up the engine and tires of your car but turn to the wheels and install a new Bilstein coilover kit.

As with any custom creation, some trinkets have sneaked past the Audi RS5 and the interior can be done in whatever way you like as long as you provide a serious wallet.
If you want one of the Senner Tuning Audi RS5s delivered you’ll have to dish out around $150.000. If however you already have the car, an upgrade for such an occasion will cost you just under $25.000.
