Natural Aspiration vs Forced Induction
Cool piece from Motorsport Magazine, they use the AMG GT as the backdrop actually...
I was fascinated to discover that Mercedes-Benz’s brand new AMG GT GT3 race car was, in one respect at least, not new at all. For years Mercedes had been hinting at an all new family of engines that would make its debut in the GT and when it arrived, the new 4-litre, V8 twin turbo motor did not disappoint. At all. And yet the racer has not this engine, but the decade old normally aspirated 6.2-litre V8 that featured in the old SLS road and racer.
I asked someone who’d know why this might be and the answer was that the old engine has all the power and torque the regs would allow and that it was a known and broadly bombproof commodity. They did not mention that it also sounds fabulous and has throttle response no turbo engine could ever match.
