The upcoming GTS channels the spirit of the last-generation M3 CSL, a lightweight version of the E46 M3 only available overseas. While it isn’t Lotus territory, the M3 GTS tips the scales at 3370 pounds, an improvement over the standard M3 coupe’s curb weight of 3700 pounds. A rear-seat deletion and uninstalling the automatic climate control and sound system are part of the weight-loss strategy. Additional measures include polycarbonate windows, dumping noise-deadening material, and fitting a lightened sports exhaust system with titanium silencers.
The new exhaust system will receive spent gases from the revised V-8 engine, which gets a displacement bump from 4.0 to 4.4 liters. Cylinder stroke has been extended from 2.96 inches to 3.23 inches, helping massage numbers of 444 horsepower and 324 pound-feet of torque. Maximum horsepower is delivered at 8300 rpm (same as the base M3) and full torque is reached at 3750 rpm.
Combine the engine with the track-optimized, seven-speed M Dual Clutch Drivelogic transmission and the M3 GTS propels itself from 0-60 mph in 4.4 seconds. Top speed is a very fast 190 mph and the coupe dashes the 1000-meter in 22.5 seconds.
As any club racer can tell you, power is not the sole name of the game. Assisting the M3 GTS are adjustable coil-over suspension, bigger brakes, steel-braided brake lines, and flat-black, 19-inch M alloy wheels. The electronic nannies, including Dynamic Stability Control, ABS, and M Dynamic Mode, have all been tuned to suit the GTS.
How much does all this special M3 performance cost? In Europe, the M3 GTS will cost 115,000 Euros, not including a 19-percent value-added tax. That translates to around $174,000 according to today’s currency exchange rates. More realistically — and assuming the M3 GTS makes it to the United States — the M3 GTS would sell for closer to $100,000, assuming similar pricing proportions as Germany.
The M3’s standard 4.0-liter V-8 makes 414 horsepower and 295 pound-feet of torque at 8300 and 3900 rpm, respectively.
