In June, we showed you the first patent images of the BMW 8 Series Convertible and Gran Coupé models, which were leaked onto the Internet. Now, Dutch portal Autovisie has gotten hold of the rest of them that give us a full, proper look at the exterior design of the two upcoming variants.

As we’ve seen before, the two cars share general styling cues with the recently unveiled Coupé, with slim headlights, trapezoidal kidney grilles and L-shaped tail lights. The cabrio is obviously as per the former sans the metal roof – replaced with a folding soft-top – and with the addition of a third brake light on the bootlid.

Meanwhile, the Gran Coupé adds the prerequisite rear doors and a longer – but still fairly low-slung – roofline, as seen on the Concept M8 Gran Coupé in March. It also gets chrome accents across the air intakes on the front bumper, at least on the non-M Sport model seen here.

The chrome trim extends to the rear bumper, stretching across the width of the bumper and wrapping around the exhaust exits. These have an almost quad-pipe look to them, despite both the Convertible and Gran Coupé expected to share the same twin-turbocharged engines as the Coupé – a 3.0 litre diesel straight-six in the 840d xDrive and a 4.4 litre petrol V8 in the M850i xDrive.

Both the Convertible and Gran Coupé will also receive an M8 variant that is expected to utilise a version of the F90 M5‘s 4.4 litre biturbo V8 and switchable all-wheel drive system, making upwards of the standard sedan’s 600 hp – and likely matching the Competition‘s 625 hp.
