A partially camouflaged prototype of the 2016 BMW X6 M (F86) was caught on camera tackling the Nürburgring in Germany.

BMW's engineers are putting the finishing touches on the upcoming X6 M which will likely come with an evolution of the V8 4.4-liter twin-turbo engine from the outgoing model. The current output stands at 555 PS (408 kW) and 502 lb-ft (680 Nm) but chances are the new variant will come with slightly more power that will be enough for a 0-62 mph (0-100 km/h) run in less than 4.7 seconds. Top speed will be once again electronically-capped at 155 mph (250 km/h) while an M Sport automatic transmission linked to an all-wheel drive system will also be on the menu.

Matching the added power will be a slightly more aggressive body featuring larger air intakes, aerodynamic side skirts and a reworked front grille. There should also be a more pronounced rear spoiler, a quad exhaust system and lightweight alloy wheels together with uprated brakes to match the extra punch.

The same changes will also be implemented in the X5 M (F85) and both cars should be unveiled before the end of the year, with sales to kick off probably early 2015.
