Transferring the immense torque of the EA825 V8 engine to the tarmac relies on a robust automatic transmission and Audi's permanent Quattro all-wheel-drive system. As power levels are pushed far beyond factory limits, minimizing drivetrain slop and deflection becomes paramount. While aftermarket drivetrain hardware for the 4K MLB Evo platform continues to expand, maintaining and upgrading your mounts and differential bushings ensures instant power delivery and long-term drivetrain integrity under heavy launches.
