Track-Weapons Clash: Porsche 911 GT3 RS Vs. Porsche 718 GT4 RS

While both are street-legal machines designed for track use, find out how the two have a few key fundamental differences that set them apart

The 911 GT3 RS and the 718 Cayman GT4 RS are the best track-focused sports cars in Porsche's current lineup

The 911 GT3 RS packs a 4.0-liter nat-asp flat-six which sits behind the rear axle

This engine is rated at 518 hp and 342 lb-ft of torque. It drives the rear wheels via either a 7-speed PDK

The 718 Cayman GT4 RS keeps the same 4.0-liter flat-six but is slightly detuned

In this flavor, the engine cranks 493 hp and 331 lb-ft of torque. Also, the engine sits in the middle of the chassis, unlike the GT3 RS

The 718 Cayman GT4 RS is not as hardcore as the GT3 RS, but is so much more than the other Cayman variants

The GT4 RS benefits from a carbon fiber hood, carbon fiber front and rear fenders, along with forged aluminum wheels. These are available with the GT3 RS as well, but being cheaper makes the Cayman GT4 RS more attractive

The 911 GT3 RS is the most track-focused 911 you can currently buy with 1895 lbs of downforce at 177 mph

One of the most impressive features of the GT3 RS is its (DRS). This is technology straight out of Formula 1, and it's a game-changer on the track

Beyond raw power, these machines are also packed to the brim with a lot of advanced hardware

The Cayman GT4 RS, while less sophisticated in some areas with standard PTV, should still offer a razor-sharp driving experience.

Both cars boast impressive braking performance thanks to massive aluminum brake rotors.

Exterior Design, the GT3 RS looks like a race car for the road.

The Cayman GT4 RS in comparison appears to be a lot more subtle

Despite the focus on aggressive performance, a more modern interior graces the 911 GT3 RS

With a cleaner and modern look, especially the 12.3-inch touchscreen infotainment system, the 911 GT3 RS's interior is more tech heavy with a dash of Alcantara

The GT4 RS's cabin while functional and just as driver-focused does feature a slightly dated design

With an analog tachometer and a speedometer, along with a dinky 7.0-inch touchscreen display that only supports Apple CarPlay, the GT4 RS's cabin seems old but nostalgic

With 9.2 cubic feet in the frunk, you can actually fit your weekend luggage if that matters to you, unlike the GT3 RS's with just 4.6 cubic feet

Weissach performance package is offered on both cars

The GT3 RS starts at $241,300. The Cayman GT4 RS, while still expensive at $164,200, represents significant savings of 77 grand.
