The forthcoming G80 BMW M3 has been spotted testing again, this time at the famed Nurburgring Nordschleife in Germany where automakers go to prove their products’ dynamic mettle. Previously seen undergoing cold-weather trials, the next-generation performance sedan is seen here being put through considerably more pace. Its driver is even having fun with some opposite lock.

There is much development to go on the aesthetic front, seeing that the test mule here is equipped with simple, circular headlamp units; these will undoubtedly be revised further along in its development. It appears to be the same story around the back, where makeshift light housings conceal items which themselves appear not to be the eventual product.

Changes to this iteration of development over the ones spotted running winter tests include a larger wheel-and-tyre set, which are home to large, possibly carbon-ceramic brakes on both front and rear axles. These naturally reside within flared wheel arches as part of BMW M’s more aggressive design language relative to its more mainstream models, while quad exhaust pipes round off the M signatures.

The rear-end of the G80 M3 mule here shows off its exhaust muffler box rather prominently, therefore a deeper rear bumper could also be in order here. Under the skin, the G80 is expected to sport CLAR (Cluster Architecture) underpinnings, which currently forms the basis of the G30 5 Series and the G11/12 7 Series.

Though images of its interior aren’t available yet, the G80 M3 can certainly be expected to be fashioned closely after that of the G20 3 Series, albeit with M-specific alterations to the seats, trim and a selection of drive modes specific to the M car. Powertrain can be expected to be a development of the 3.0 litre, twin-turbo inline-six cylinder engine from the F80 M3 and F82 M4, and is tipped to grow output to 465 hp.

Driveline is expected to remain rear-wheel-drive, with the use of an eight-speed automatic or six-speed manual gearbox. As probably indicated by the drifting photographed here, a limited-slip differential on the rear axle should be present too. Meanwhile, the CLAR platform should aid in mitigating any weight gain, thanks to its greater emphasis on usage of aluminium and high-strength steel as well as carbon-fibre sections.
