Fifth Gear puts together a comparison between the BMW M3 GTS and Porsche 911 GT3 RS. The famous hosts Tiff Needell and Vicki Butler Henderson take the two fabulous cars on a race track and give us a Fifth Gear-like review.

The BMW M3 GTS is produced at the BMW M manufacturing facility. In addition to a larger and more powerful V8 engine, exclusive tuning of the 7-speed M Dual Clutch Transmission with Drivelogic and modified suspension technology, the car, which is designed for club sport use, has also been specifically optimized with regard to aerodynamics and lightweight construction. BMW M3 Coupe features a 331 kW/450 bhp engine .

Featuring a transmission and suspension configuration which has been optimized for the racetrack, the BMW M3 GTS accelerates from 0 to 100 km/h in a mere 4.4 seconds. The car reaches the 1,000 meter mark from a standstill in just 22.5 seconds.

In a nutshell, the 911 GT3 RS is a genuine racing car approved for the road. It’s been formulated for demanding competition use with a special suspension, weight-saving components and large carbon-fiber wing spoiler – and even comes complete with special livery.

The 911 GT3 RS features a new and more powerful 3.8-liter flat-six — up from 3.6-liters last year, and now producing 450 horsepower. The RS runs zero-to-100-km/h time in 4.0 seconds. The only transmission is a six-speed manual but, compared to the regular GT3, the RS’s has a single-mass flywheel for higher racing loads.

So, which one is a better car? Let’s have a look…
