Testing of the new generation BMW M4
continues with yet another prototype spied in and around the Nurburgring with
less camo than ever. The range-topping member of the 2021 4-Series Coupe family
boasts a different grille design, with horizontal slats, a more muscular hood
and a more aggressive front bumper with cutouts on each side and wider lower
air intakes to help with cooling along with a thin apron.
The bulging fenders, bespoke side mirrors,
bigger side skirts, new rear bumper with a diffuser and quad pipes plus a
discrete boot lid spoiler are also visible in the latest spy shots. The tester
features black alloy wheels, contrasting the matte blue paint finish of the
body, and light brown leather upholstery in the cockpit, which will otherwise
look identical to the latest 3- and 4-Series, save for a few M-specific
upgrades.
BMW has already confirmed that the
twin-turbo 3.0-liter straight-six engine will provide the fire power, in two
variants. In the base model, it will deliver 473 HP paired to
a six-speed manual transmission (an 8-speed automatic will likely be optional)
and rear-wheel drive, whereas the Competition will bring 503 HP and 650 Nm of torque to the party. The upper spec will launch
with an 8-speed automatic transmission and rear-wheel drive, but it will be
joined by a four-wheel drive variant later on, mirroring the bigger M5.
The 2021 M3 and M4 will be officially
unveiled in mid-September, while the xDrive AWD models will follow later on.
