Porsche has graced us with two incredible RS cars in 2022, and we’re here to find out which is best.

The new GT3 RS isn’t just inspired by motorsport, it’s a full-blown race car. The engine is a 4.0-litre naturally-aspirated flat-six revving to 9,000rpm and producing 518bhp. It’s got 860kg of downforce at 177mph and 406kg at 124mph, well over double those of the 991.2 GT3 RS it succeeds. But worry not, this is still not a slow car - 0-62mph in 3.2 seconds and a top speed of 184mph.

However, if you’ve ever wondered what would happen if Porsche stuffed the stupendous GT3 engine into the back of its mid-engine baby-brother, the Cayman… the GT4 RS is your answer. It’s the most hardcore, powerful and track-hungry Cayman Porsche has ever made. 493bhp, 332lb ft of torque and 0-62mph in 3.4 seconds. The question is, can it give the more expensive GT3 RS a run for its money?

Top Gear Magazine’s Jack Rix and Ollie Marriage give us the rundown on track.
