During the Industry Pool at the N?rburgring I have filmed the 2023 Mercedes-AMG GLC63 S testing on track and yes, it gets a 4-cylinder hybrid engine! Mercedes introduced the redesigned GLC a few months ago and now attention is turning to the high-performance variants. While spy photographers have already snapped the upcoming GLC 43, we?re getting a better look at the range-topping GLC 63. Caught undergoing testing in Europe, the high-performance crossover has a wide Panamericana grille which is flanked by LED headlights. They?re joined by sportier side skirts and lightweight wheels that are backed up by a beefy braking system with red calipers. The sporty styling continues out back as the model has a unique rear bumper and a four-tailpipe exhaust system with squared off tips. It?s also interesting to note the rear spoiler is camouflaged, so it might be slightly different than the one found on the regular model. We didn?t get close enough to snap interior pictures this time around, but previous shots have shown carbon fiber trim as well as a flat-bottomed steering wheel. Other highlights will include supportive sport seats, a 12.3-inch digital instrument cluster, and an 11.9-inch infotainment system with a portrait orientation. The interior isn?t the only thing that is all-new as the upcoming GLC 63 will feature a plug-in hybrid powertrain just like the C63 E Performance. The latter model is slated to have a turbocharged 2.0-liter four-cylinder engine that produces 470 hp (350 kW / 476 PS). It will be paired with a rear-mounted electric motor that develops 201 hp (150 kW / 204 PS) and this will give the car a combined output of 671 hp (500 kW / 680 PS) and 553 lb-ft (750 Nm) of torque. If those numbers carryover to the crossover, the redesigned model will have 168 hp (125 kW / 170 PS) and 37 lb-ft (50 Nm) of torque more than the outgoing GLC 63 S. That?s pretty impressive when you consider the ?old? model rocketed from 0-60 mph (0-96 km/h) in approximately 3.6 seconds before hitting an electronically limited top speed of 174 mph (280 km/h).
