Snapped in both cases by the walkoART YouTube page in the pouring rain, the models in question are the GLC 63 Coupe and the regular GLE 63, both devoid of any badges and sporting flat white paint finishes with extensive layers of black-and-white wrapping around the front and rear facias, as well as the sides in the case of the latter.
Identified from their less sporting siblings thanks to the noticeable drop in ride height, redesigned front bumpers with wider air intakes, sportier alloy wheels and extended wheel arches, both the GLC and GLE will come powered by the familiar 4.0-litre bi-turbo V8 engine, which in the case of the former will have outputs similar to the C63 (350kW/650Nm and 375kW/700Nm in the 63 S), and the latter on par with those of the E63 (420kW/750Nm and 450kW/850Nm in the S).
Given the amount of pre-production paraphernalia still present, expect both to only debut in 2019.
