When tested on an engine dyno this combination makes 842 horsepower and 779 lb-ft of torque. This is sent to all wheels through the 4MATIC+ system. Vossen makes the wheels exclusively for RENNtech, measuring 20 x 10 front and 20 x 10.5 rear. Wrapped in Michelin Sport Cup 2 rubber, it allowed for a flawless holeshot in the record-setting run.
