Word is that the next-generation BMW 3 Series, codenamed G20, will make its debut later this year at the Paris Motor Show in October. That’s no big surprise, as production-ready test mules have been spotted testing in Germany.

We had a decent look at a G20 test mule earlier this month, which also revealed the premium compact exec’s interior. While that car was an M Sport beneath the camouflage, this set of spyshots are of a regular trim level, with smaller wheels (Hankook to be the OE tyre?) and a less aggressive front bumper.

The level of disguise is similar to before, covering the entire car except for the roof and a small section of the bonnet, even if the new grid patterned camo is less distracting. But with no padding, the shapes and lines of the new 3 Series are clear, and it’s no big departure from today’s car – evolution is the name of the game for successful icons.

In front, the kidney grille appears larger and rounder than the F30’s, and we get a sneak peek at the new car’s headlamps. There’s a radar sitting in the lower intake for driver assist systems. At the back there’s a shapely boot lid and chrome-tipped dual exhaust pipes, but BMW gives little else away. The location of the reflectors are lower here than on the M Sport bumper, which also has vertical vents at the edges.

The interior will be a bigger change, as spied previously. Spotted items include a digital instrument panel with fixed half rings, like in the G30 5 Series, and a slim centre stack that might share a same style with the upcoming Z4 roadster. The centre console is a huge departure from the current layout – it houses the push start button and a new, more flush iDrive controller.

Here’s how we think the next-gen BMW 3 Series will look like.
