BMW unveiled the M4 GTS back in 2015 so it’s
surprising that spy photographers recently caught a hardcore prototype
undergoing testing in Germany. Looking far more extreme than the limited
edition model, this prototype has been equipped with canards and a larger front
splitter. The styling changes don’t stop there as the coupe has larger front
fender vents as well as new vents above the front wheels.
Moving further back, the M4 GTS prototype has
extended side skirts and what appears to be a reduced ride height. The
aerodynamic styling cues continue at the rear as the car features a massive
wing and a larger rear spoiler. Rounding out the changes are an extended rear
bumper and an aggressive diffuser.
It remains unclear why BMW is testing the car but
the model could be the basis for a new limited edition that is geared for track
days. This remains unconfirmed but the M4 still has some life left in it as the
next-generation model isn’t expected to arrive until 2020 or 2021.
The M4 GTS was a
high-performance model which came equipped with an aerodynamic body kit that
included an adjustable front splitter, a carbon fiber diffuser and a large rear
wing. The car also had a new hood, a titanium exhaust system and eye-catching
lightweight alloy wheels.
The focus on performance continued in the cabin as
the rear seat was removed to reduce weight. Designers also replaced the door
handles with pull loops and installed a “lightweight center console” which was
covered in Alcantara upholstery.
The biggest changes occurred under the hood as the
3.0-liter TwinPower Turbo six-cylinder engine was equipped with a water
injecti442 lb-ft) of torque. The engine was connected to a seven-speed dual-clutch
transmission which enabled the car to accelerate from 0-100 km/h in
3.8 seconds before hitting a top speed of 305 km/h. This allowed the
M4 GTS to lap the Nürburgring in 7 minutes and 28 seconds – nearly 30 seconds
faster than the standard M4.
Production was limited to 700 units and only 300 of
them were offered in the United States.
