The 8 Series Gran Coupe is a good-looking BMW

Is this four-door, £100k M850i the new 8 Series sweet spot? Or are we wrong?

Published: 18 Jun 2019

We’ve always wondered about the new 8 Series. Not special enough. Nor charismatic to be a range-topper. Is this new Gran Coupe the big BMW’s sweet spot? Certainly looks sweet, in any case.

Welcome then, to the brand new BMW M850i. As you can see, it has four doors. And as you probably can’t see, it’s 201mm longer than the 8 Series Coupe from whence it came. Naturally, it’s also wider, and a touch taller than that coupe, because this one can accommodate up to four adults*.

So, inside there’s a new extended centre console, along with a new rear seat unit that features two individual seats, along with a little third one snuck in between. If you have four adults and a child, or four adults and a small to medium-sized dog, it’ll suffice “for use on short journeys”.

BMW promises loads more shoulder and head room in this car than in the coupe, which is handy, and there’s loads of leather and options you can empty your banking app on. The rear seats can fold down too, increasing the 440-litre boot space to… something unspecified but presumably much larger.

The front of the GC carries over the new 8 Series’s signature: angry eyes, a big grille, lots of vents and scoops in this M850i spec. From there however, it rises up to a slightly more upright windscreen for better headroom, and of course, that overall taller roofline. In side profile it looks decent. Rear too, looks good. It all feels very resolved and nice and... unlike the current BMW norm.

Naturally, the suspension and damping have been amended to deal with the additional height, weight and length. Adaptive dampers are standard, there are “extremely stiff suspension springs” for less body roll, and the four-wheel-drive cars get active steering. There’s active roll stabilisation as an option, and an M Sport diff (standard on the M850i, optional on others).

Engines mirror the standard 8 Series cars, so: a range-topping 526bhp twin-turbo, 4WD petrol V8 (M850i) that’ll do 0-62mph in 3.9secs, a rear-drive petrol straight-six with 336bhp (840i, 0-62mph in 5.2secs), and a diesel 4WD sixer (840d xDrive, 0-62mph in 5.1secs).

It’s 70kg heavier than the 8er coupe, but features aluminium throughout its body – the bonnet, front panel, subframe, rear bumper support and so on. The boot lid is actually plastic, and you can option carbon things and a carbon fibre roof. Which you must.

Prices start at £69,340 for the rear-drive 840i, £73,915 for the 840d xDrive, and £97,720 for the M850i. You can bet your house on there being an M8 Gran Coupe arriving in the near future, which looks set to match a 616bhp V8 to a four-door body. We suspect that’ll be the M8 to go for...
