BMW 3 series 2018 Next Three Codenamed G20 revealed.

The next BMW 3-series, codenamed G20, aims to close the gap with the new class-leaders, the latest Mercedes-Benz C-class and new Jaguar XE. Gone are the days of BMW hegemony in this important sector, and they’re pulling out all the stops to close the gap.

It’s not so long ago that Munich released a facelifted version of today’s 3-series, but we can lift the lid on its successor – the all-new model is coming in 2018. This is BMW’s best-selling model by some margin – it’s vital that they gun for class honours.

Our latest spy shots – click on the image above to browse the full gallery – reveal BMW’s next-gen 3-series being tested in Munich. Little has changed externally, compared to previously captured prototypes, but this time we’ve been afforded our first glimpse of the interior.

Design: ‘modern without bling, functional yet more emotional’

The current 3-series is aerodynamically efficient and cleverly packaged, if a little generic in the BMW jellymould. The design needs to move on, insiders admit, and it will do so by redefining the overall proportions, the relation between the more muscular body and the sleeker greenhouse, and the stance which will likely be sportier.

Our artist’s impression (below) points to a modest refresh: sharper creases, harder edges, more adventurous radii and even tighter cutlines, our Munich moles suggest.
