The upcoming BMW 8 Series has been spied once again in both coupe and convertible forms, ahead of a likely reveal later this year.
Both versions are wearing a little less camouflage than previous prototypes, showing off more production parts like the bumpers and light units.
It appears both vehicles are M Sport cars, largely due to the aggressive front and rear bumper treatments along with the large alloy wheels housing blue brake calipers and large brake discs.
For the first time we can see the production front bumper, which also features a radar sensor mounted into the lower intake – likely for the vehicle's autonomous emergency braking and adaptive cruise control systems.
There's also less camouflage over the double-kidney front grille than previously, showing a very wide iteration of BMW's signature frontal design cue.
Between the two vehicles, the 8 Series coupe has large intakes and a more aggressive lower front bumper treatment, potentially hinting at a hotter M Performance model with functional intakes and aero components compared to the convertible's sporty styling pack.
Comparing the vehicles at the rear shows some slight differences between the two models. The coupe gets a more aggressive rear spoiler treatment integrated into the bootlid, along with a more prominent rear diffuser-style insert – however, the convertible's bootlid does appear to have a false panel concealing the rest of the tail-lights, so it could be the same.
We can also see a quad-tipped exhaust peeping through the trapezoidal finishers of the coupe, indicating this vehicle is likely fitted with a V8 engine. The convertible, meanwhile, gets away with bad lighting concealing what's behind its tailpipe finishers.
Both also feature an L-shaped slit on each side of the rear bumper with integrated reflectors.
Our photographers also managed to snap the above image of the coupe's interior, too, though you can't see much other than the steering wheel borrowed from the 5 Series and 7 Series, along with the fully-digital instrument cluster ahead of the driver.
The rest is covered in grey sheeting, but we have got a glimpse of the new flagship's exterior and interior undisguised previously – you can see those photos here.
It's believed the BMW 8 Series will be officially revealed sometime later this year, complete with a range of turbocharged six-, eight- and possibly 12-cylinder engines. Stay tuned for all the latest updates over the coming months.
