We know BMW has been working on the next-generation 3 Series, codenamed G20, for a while now. This week, we’ve got the first set of spy shots of the wilder M3, codenamed G80, doing its developmental rounds around Munich.

Although the sports saloon is in the early stages of development and the prototype is heavily camouflaged, we can still glean a few hints as to what the changes could be. The M3 is sure to get a wider track than the regular 3-Series it will be based on, and the final car will sport wheel arches and fenders that are still wider and beefier than what you see in this tester. You can see from the images that the brake discs and calipers are also large, while at the rear, typical M quad-exhaust tips can be seen.

While it’s not visible in the photos, being an M car, it’s sure to sport gaping air intakes up front, which should be more visible in subsequent testers as development progresses. There isn’t much that we know about powertrain and output figures, but we expect a twin-turbocharged inline-six putting out nearly 500 horsepower, which will be a significant upgrade over the current model’s 425 horsepower.
