The GTS model of the BMW M4 Coupe was first introduced at the Pebble Beach Concours d’Elegance in August 2015. In 2016, a production version of the car was already introduced.
One of the features that probably attracted a horde of car enthusiasts is its use of water injection technology. It’s reportedly the first production automobile to use it in almost two decades.
For the M4 GTS, BMW reimagined the old concept of the water injection system. The intake air is sprayed with cooling mist to help control the temperatures of the intake as well as the inside of the cylinder. This also helps improve combustion and boosts the turbocharged engine by lowering the stress and knocking caused by heat. The system also helps reduce emissions and somewhat improves the car’s fuel economy. Even if the water tank runs dry, the system will still work.
The M4 GTS boasts a meaner punch under its carbon fiber hood compared to the standard M4. From the 317 kW power and 550Nm torque of the standard model, the GTS version has an improved power of 368 kW and torque of 600Nm. Although, both versions reportedly have the same 3.0-liter twin-turbocharged straight-six engine. The GTS’ transmission is a seven-speed MD DCT, which sends all the power to the rear wheels.
Another difference between the two models is that the GTS is 60 lbs lighter than the M4 Coupe. To make it lightweight, rear seats were taken out, the door panels and center console were lightened, and straps were favored over interior door handles.
The lighter weight has enabled the GTS to run from zero to 62 mph in just 3.8 seconds with a top speed of 190 mph. According to BMW, the M4 GTS clocked in 7 minutes and 28 seconds when it ran a lap at the Nürburgring Nordschleife track, around the same time as that of the Porsche Carrera GT. This track time makes the GTS faster than the base M4 by 24 seconds and the M3 GTS by 20 seconds.
The M4 GTS is also equipped with Michelin Pilot Sport Cup 2 tires, carbon-ceramic brakes, adjustable rear wing, and titanium exhaust. There is an optional upgrade available, which includes a harness, a fire extinguisher, and an Acid Orange roll bar. It’s no wonder it was used in Moto GP motorcycle racing championships as safety cars.
