Behind the rear axle of the GT3 RS lives a 4.0-litre direct-injection horizontally-opposed six-cylinder engine with 368kW of power and 480Nm of torque at its disposal. Power is sent to the rear wheels via a "specially developed" dual-clutch transmission.

The 911 GT3 RS is able to complete the 0-100km/h dash in 3.3 seconds and the 0-200km/h sprint in 10.9 seconds. The new 911 GT3 RS is able to complete a lap of the Nurburgring Nordschleife in 7 minutes 20 seconds, bettering the lap time of the Carrera GT by a full nine seconds.

By way of comparison, the regular GT3 makes do with a 3.8-litre motor that's 18kW less powerful and has 40Nm less torque; it's also 0.2 seconds slower to 100km/h.

Thanks to a clutch of lightweight additions to the car, including a new magnesium roof, and carbonfibre engine and boot covers, the GT3 RS weighs 10 kilograms less than the GT3 — or around 1420kg.

The GT3 RS' body is based on that of the 911 Turbo. Differences include a front lip spoiler that juts out prominently, a high-rise rear wing, and vents at the top of the front wheel arches that help generate downforce on the front axle.

To ensure that the GT3 RS tracks straight and true, the car features 21-inch alloy wheels fitted to the widest tyres available on any 911 model, as well rear axle steering and a fully variable differential lock on the rear axle.

On the inside, the GT3 RS features carbon bucket seats similar to the set used in the 918 Spyder, as well as a roll cage behind the driver and front passenger's pews.
