The Last Naturally Aspirated Argument
By 2021 the case for turbocharging had been settled everywhere else. More torque, lower down, better emissions numbers, and no real cost to the way a car feels unless you were paying close attention. Porsche turbocharged the entire 911 range and the cars got faster. Almost nobody argued.
The GT3 was the exception, and it stayed the exception on purpose. Porsche's motorsport division kept the 4.0-litre naturally aspirated flat-six — an engine closely related to the one in the 911 RSR and the Cup cars — because a turbocharger flattens the top end, and the top end is the entire point. It revs to 9,000 rpm. Peak power arrives at 8,400. There is no shortcut to that noise.
Then they did the rest of it properly: double-wishbone front suspension from the RSR, a swan-neck wing hung from above so the airflow underneath stays clean, centre-lock wheels, and a cockpit stripped of anything that did not earn its weight. Six minutes fifty-nine at the Nordschleife. Forget the destination — focus on the curves.
