Thanks to @Y14nny for joining us for this one!Here we go Porsche fans - this one’s for you! We’ve got our hands on the glorious Porsche 911 GT3, and it’s going up against the Cayman GT4 RS! The question is, which will come out on top? Well, let’s take a look at the stats, starting with the GT3. It rolls up equipped with a 4-litre naturally-aspirated flat-six, and this can put down 510hp and 470Nm. This is sent to the rear wheels through a 7-speed dual-clutch, and to pick one up now it will cost around £146,000. Then we come to the Cayman. It’s also powered by a 4-litre naturally-aspirated flat-six, but in this instance, the output is 500hp and 450Nm. It’s also a super light car, weighing in at just 1,415kg! In comparison, the GT3 comes in slightly heavier, at 1,435kg.So the GT3 has slightly more power, but will the weight difference prove decisive? There’s only one way to find out for sure… LET’S RACE!Porsche GT2 RS v McLaren 765LT v Ferrari 296 GTB: Change your car with Carwow:
