In Part 1 of our two part track battle, we see our video team head out onto the Killarney RaceTrack in three German performance coupes.
Going head to head in a hot lap battle are the BMW M4 Competition Pack, the Mercedes-AMG C63S and the new Audi RS5.
The three Germans are closely matched, with the Mercedes offering the most power and torque from its bi-turbo V8, the BMW being the lightest and the RS5 being the only car here with all-wheel-drive.

Stay tuned for Part 2 where we reveal which car was the fastest on the day.
