First and foremost, the video below is unfortunately available in German only, but this doesn’t stop us from enjoying two of the best M3s of all-time: BMW M3 GTS and the E30 M3 Sport Evolution.
Before we jump into the drifting footage and race track action in Ascari, Spain, let’s recap some of the major points around these two fantastic M3s.
BMW M3 Sport Evolution. In 2007, “Evo” Magazine rated the E30 M3 Sport Evolution top of all the M series BMWs at time of print. The E30 M3 Sport Evolution was BMW’s response to the Mercedes 190E 2.5-16 Evolution. The M3 was built to a set of specifications to comply with the FIA’s Group A Touring Class regulations, which required an initial run of 500 road cars.
After experimenting with several different engine combinations, BMW Motorsport settled on the M10 block as the starting point for its S14 plant. Designed in just fourteen days, the S14 was a mix of existing parts. The block was derived from the two-liter four engine found in the 320, equipped with a DOHC, sixteen valve head. Sharing its bore and stroke with the bigger six cylinder engine, the new S14 displaced just over 2.3 liter. In stock form it produced a 200 horsepower, with the competition spec engine putting out at least 300 horsepower at 8000 rpm. 0 to 60 mph comes in 6.1 seconds.
BMW M3 GTS. M3 GTS embeds the core values of the M Division and takes the already sporty M3 to a new level.
Thanks to an increase in engine displacement and some fine-tuning to the engine, the BMW M3 GTS produces 450 horsepower and ensures superior performance.
The core of the development was the landing gear, based on the BMW M3 GT4 and transposed into a street-legal vehicle. The rear wing was first seen in World Touring Car Championship WTCC cars and now makes its way into GTS as well.
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.
The supreme sporting potential of the BMW M3 GTS is underlined, inter alia, by a power-to-weight ratio that has been lowered to 3.4 kg per hp. 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 1000 meter mark from a standstill in just 22.5 seconds. Top speed is 305 km/h.
The original M3′s head design was essentially a sawed-off 2.3-liter version of the 3.5-liter inline six unit from the M5/M6 line. A forged crank, improved oil flow and stout internals filled the short block. A Bosch Motronic injection system fed the four-valve head, the engine ultimately cranking out a respectable 192 bhp at 6750 rpm. It was linked to a close-ratio, five-speed dogleg gearbox hooked to a limited-slip diff.
