We took advantage of the spring in Europe to go on a road trip to the Großglockner high alpine road in Austria with the Eibach Audi RS 5 and our Mercedes-AMG C 43.

The performance engineering company RaceChip manages to increase the power of the BMW (G11) 740i from its stock 326 HP and 450 Nm to strong 409 HP and 525 Nm.

Two of our show cars with different concepts challenge each other: Audi versus Mercedes, five versus six cylinders. Which car can produce more power on the dyno, sounds better and accelerates faster on the German Autobahn?
