The upcoming BMW 8 Series range is set to feature an M850i M Performance variant, according to a new report.

BMW Blog claims the Bavarian manufacturer wants to bridge the gap between the entry-level 840i and the flagship M8 with a focused M Performance model.

While not confirmed, the M850i is expected to get a version of BMW's 4.4-litre twin-turbo V8, developing around 500hp (373kW) with drive sent to all four wheels.

It's also likely the M850i will get M Sport upgrades like sports suspension bigger brakes, torque vectoring and light alloy wheels. BMW Blog also says the variant could get a carbon-fibre roof, too.

The production version of the BMW 8 Series is expected to debut sometime next year, and it's also expected to look very similar to the Concept 8 Series that previewed it (pictured).
