New 992 GT3 RS
“Around 500hp is the sweet spot,” said Andreas Preuninger, director of GT Road Cars, Porsche. “Any more and you need more of everything, such as bigger brakes, and that all adds weight.” The GT3 RS has 525hp, just 15 more than the GT3 which, says the GT boss, is enough. There’s never been any doubt the GT3 RS would come, but now it’s here we can confirm the details and quash the rumours. The engine remains a 4.0-litre flat six. All the talk of a larger capacity, or even turbo or hybrid-assisted GT3 RS was just that: talk. The power bump over the GT3 might be marginal, but Andreas claims it’s how the GT3 RS produces its power that’s significant.
The 4.0-litre’s 525hp is developed at 8,500rpm, just 500rpm before its 9,000rpm red line. Peak torque of 465Nm arrives at 6,300rpm. That’s 200rpm higher than the GT3’s 470Nm peak. To achieve that it’s got a bespoke intake system and differing cylinder heads for improved lubrication under the high G-loads that the RS will subject its engine to. Hotter cams with bigger overlap also feature, while the exhaust is RS-specific, too.
That flat six is attached to the familiar seven-speed PDK paddle-shifted transmission. This
