On paper the deficit between the two cars is roughly 100 horsepower. In practice, it looks even greater as the A45 AMG demolishes the 335i from a low speed roll. From a stop the 335i is given the hit and a lead but the A45 AMG very quickly reels it in and passes. It is not close at all.
It is useful to see just how much faster a tuned M133 is than a stock N55 but Rebellion may not want to tout this race too much as there are plenty of 335's on BimmerBoost that would make this A45 AMG look like it is standing still. That said, this AMG four-cylinder all wheel drive dual clutch drivetrain continues to impress.
