Mercedes are cracking on with development of the new ML-based SUV coupe and our spies were on hand to catch it on video. It was caught wearing the same black and white camoflage seen on earlier prototypes and gives a first opportunity to check out the brand new model in motion.

The final moniker is yet to be confirmed but we expect it to be either the MLC or the ML Coupe. As the name suggests, it will be based on the brand's existing M-Class platform whilst adopting a sportier sloping roofline to compete with rivals such as the BMW X6.

Engine options are likely to be inherited from its M-Class sibling and will include a 3.0-liter V6 twin-turbo boasting 333 PS (245 kW) and 354 lb-ft (480 Nm) of torque. On the higher end of the scale, the MLC 63 AMG will get the twin-turbo V8 5.5-liter that could pump as much as 558 PS (410 kW) and 758 Nm (560 lb-ft).

Rumours suggest the MLC / ML Coupe will be unveiled at the 2015 Frankfurt Motor Show.
