The next-gen BMW 5 Series, codenamed G30, is now in the last leg of the development and testing process, and the new car is due to surface later this year. We’ve seen a couple of sets of spyshots, and while the shape is familiar, test mules have been well camouflaged so far and details have remained under wraps.

Based on what we’ve seen so far, commissioned rendering expert Theophilus Chin to come up with simulations of how the production G30 might look like, with inspiration from its big brother, the G11 BMW 7 Series. Shapes of the elements we’ve seen so far + detailing from the Seven = our images here.

As seen on G30 mules, the headlamps of the new 5er are more organic in shape and LED DRL design (two full circles, flat bottomed) compared to the G11, and its kidney grilles smaller in size. Will the Seven’s aero-enhancing air flap control also feature in the G30?

Munich has so far kept the lower bumper of the new Five well-hidden, so we took the liberty to fit in a 7 Series-style lower intake, replete with full length chrome bar “supporting” the license plate and LED foglamps at each end. It’s a width-enhancing cue.

We’ve also included 7 Series-style Air Breathers just behind the front wheels, but not the full “hockey stick” – the limo’s chrome strip that runs along the lower edge of the doors, highlighting its long wheelbase. Overall chrome content is toned down compared to the Design Pure Excellence-equipped G11.

The rear you see here is a classic BMW rump, not too different from the F10’s behind. Details such as the triple-bar LED rear lamp signatures and shape of the tail pipes are as seen on the development cars. Instead of a full chrome frame for the twin pipes in Seven fashion, we opted for a less ostentatious straight-line chrome accent in between the tips.

Based on previous spyshots, we’re expecting the G30 5 Series interior to take after its big brother’s cabin style. The dashboard will be a familiar sight, that’s for sure.

The new 5 Series – which will continue to be made in saloon, Touring (wagon) and GT bodystyles – sits on the same oberklasse (OKL) platform as the latest 7 Series, which shed up to 130 kg in weight thanks to BMW’s Carbon Core construction. Will we see a similar level of weight loss in the upcoming 5 Series?
