Names and other finer details are unclear at this stage, but the top-performing MLC-Class (or M-Class Coupe perhaps) could potentially be called the MLC 63 AMG, or the ML 63 AMG Coupe.
Front styling on the AMG version is more aggressive than the regular MLC-Class, as expected, although both versions appear to be wearing the same wheels and tyres in their respective spy photos.
At the rear, the AMG may be sporting a slightly larger wing although heavily camouflaged, while the regular model’s twin exhaust has been swapped for a quad-tailpipe setup.
Power is expected to at least match the current ML 63 AMG, which produces 386kW and 700Nm from its 5.5 litre twin-turbocharged V8 engine, fed to all four wheels through a seven-speed dual clutch automatic transmission.
By comparison, the MLC 63 AMG’s main rival in the BMW X6 M currently gets 408kW and 680Nm from its smaller 4.4 litre twin-turbocharged V8 engine, transmitted through a six-speed automatic.
A new 4.0 litre twin-turbocharged V8 currently under development from AMG may also be the power plant of choice for the MLC 63 AMG, but power outputs on that unit are unclear at this stage.
The MLC-Class in both regular and AMG guises is expected to debut early 2015, but will be beaten to the market by the new BMW X6, due by the end of this year.
