It seems like we’ve been waiting forever for the next BMW 4 Series, but we’re now on the home stretch. Munich has already revealed a concept previewing the coupé earlier this year, and these spyshots show that development is at an advanced stage.

The prototypes that you see here have also shed some of its hard disguise, giving us a clearer look at what the finalised shape will be. And while BMW still appears to be keen on hiding the massive (and rather controversial) full-height double kidney grille already shown on the Concept 4, the big nostrils are still visible underneath, as is the hexagonal mesh with the raised “dashes”.

The rest of the front bumper design is still obscured, but we expect it to follow the look seen on the show car, which incorporates a U-shaped air intake underlining the grille, as well as larger inlets on either side. The headlights, which feature quad projectors and U-shaped LED daytime running lights on these mid-range units, are slightly larger than on the Concept 4, but are still fairly slim in design.

Elsewhere, BMW seems to be adding some distance between the 4 Series and its close relative, the 3 Series, drawing more styling cues from big brother 8 Series. The glasshouse is sleeker and tapers more severely towards the rear of the car, where it has also sprouted a pair of serious hips that give it a more voluptuous appearance. The trademark Hofmeister kink has also been watered down, just like the concept.

Moving to the rear, there are three-dimensional L-shaped tail lights and a large diffuser-like bumper insert on this M Sport model, and it’s encouraging to see that BMW has stuck with real tail pipes. Previous spyshots has already showed the full interior, the dashboard having been lifted wholesale from the G20 3 Series.

The engine lineup should closely mirror that of the G20, with a revised range of three-, four- and six-cylinder engines, as well as perhaps a plug-in hybrid variant and the obligatory M4. The company has already confirmed that the car will be offered with a S58 3.0 litre twin-turbo straight-six with either 480 hp or 510 hp.

The former will be the only model offered with rear-wheel drive and a six-speed manual gearbox (all-wheel drive and an eight-speed automatic transmission should be standard fit on the more powerful Competition). An all-electric i4 will also go on sale in 2021, based on the four-door Gran Coupé.
