The all-new BMW 3 Series G20 has been spotted once again and this time it was undergoing preliminary testing in Scandinavia.

We are dealing with an early prototype featuring provisional headlights and taillights attached to a body that clearly doesn’t have all the production pieces. The proportions of the car have remained pretty much the same compared to the current model, but hiding underneath the skin is the CLAR platform that will bring a healthy weight loss.

It’s the same architecture that has underpinned the 7 Series and will also serve as foundation for the upcoming 5 Series. However, the weight loss won’t be as significant compared to its two larger brothers, but even so it’s a more than welcomed diet.

Judging by the dual exhaust tips, this could be a prototype based on the 340i model, but with these early prototypes you never know for sure. An upgraded lineup of four- and six-cylinder engines will be offered and at least one plug-in hybrid derivative will be part of the family. A new M3 will join the range at some point after the standard model’s arrival and will likely be powered by an evolution of today’s turbocharged 3.0-liter six-cylinder engine.

BMW will probably decide to introduce the all-new 3 Series in the second half of 2017 as a 2018 model year. A possible venue for an official reveal is the 2017 Frankfurt Motor Show set to take place in September next year.
