Performance SUV follows C-Class cousin in ditching V8 for four-pot PHEV system

Progress is impossible without change, or so they say. For the hottest Mercedes-Benz GLC, this means forgoing its much-loved twin-turbocharged 4.0-litre V8 petrol engine for a mesmerisingly complex plug-in hybrid drivetrain.Launched in the new Mercedes-AMG C63 S E-Performance earlier this year, this matches an updated version of the A45’s 2.0-litre turbo four-cylinder engine with a rear-mounted 400V electric motor to give the new GLC 63 S E Performance 671bhp and 752lb ft of torque – figures that not only place it at the top of its class but also 69bhp and 236lb ft ahead of the old GLC 63 S.It’s also a significant 256bhp and 383lb ft more than the new GLC 43, which uses the same M139 engine but in a lower state of tune and with only mild-hybrid electrification.The inclusion of a 4.8kWh battery – admittedly more for enhancement of performance than efficiency – also allows the GLC 63 to travel for up to 7.5 miles on electricity alone.It can’t handle DC rapid charging, but a sophisticated energy recuperation system modelled on that used by Mercedes’ Formula 1 racers (with four settings) quickly and effectively charges it on the go.You can also choose between no fewer than eight driving modes and four stability control settings. Predictably, however, there’s a catch: at 2235kg, the GLC 63 is now 300kg heavier.Hot GLCs are set apart from lesser ones by a deeper front bumper, AMG’s signature Panamericana grille, new trim elements within the wheel arches, wider door sills, AMG mirrors, a large roof spoiler and a uniquely styled rear bumper sporting four rectangular tailpipes.
