Far more than just a body kit, the successor to BMW’s M3 GTS comes equipped with a 3.0-liter, twin-turbocharged straight-six engine that features water injection technology to develop just under 500 horsepower to the standard M4’s 425 and an increase in torque to 442 pound-feet. A seven-speed M DCT transmission channels the power exclusively to the rear wheels. This translates to a 0-to-60 mph run of just 3.8 seconds and a top speed of 190 mph.
Also part of the GTS package is a series of weight savings techniques, culminating in reduction of 136 pounds. The rear seats have been deleted, the center console and door panels are lighter, and straps replace the interior door handles. BMW’s M GmbH has also tweaked the chassis. On board is a three-way, manually adjustable coil-over suspension and new anti-roll bars and supporting mounts. Steering has been adjusted thanks to retuned power assist and M has tinkered with the active rear differential.
Other highlights include 265 front and 285 rear Michelin Pilot Sport Cup 2 tires covered unique wheels, and housing carbon-ceramic brakes. The M4’s aluminum hood has been replaced with a carbon-fiber one and its adjustable rear wing, rear diffuser, and front splitter all use carbon fiber construction. A titanium exhaust makes everything sound luscious, too. For some extra coin, the optional Clubsport Package adds a fire extinguisher, six-point harness, and an Acid Orange roll bar.
Of the 700 total units, 300 will be coming to the U.S., each commanding £120,500 (about $180,000), though it may convert differently. Customers are able to choose from a small number of exterior paint colors, including Mineral Grey, Sapphire Black, Frozen Dark Grey, and Alpine White. By comparison, the BMW M3 GTS from 2010 only came in burnt orange.
