The high-octane Mercedes-AMG GLC 63 S has roared onto UK roads, featuring turbocharged hybrid power for £121,820.  

While Mercedes' decision to ditch V8s for four-cylinders in smaller AMG models has sparked debate, the GLC 63 S's M139I unit leaves little room for complaint. This 2.0-litre powerhouse, bolstered by an electric motor and 6.1kWh battery, eclipses the previous model's 503bhp V8, making 671 bhp and 1,050Nm of torque. 

Mercedes says this is enough to launch the car from 0-62mph in 3.5 seconds, before reaching its limited top speed of 155mph.

The base version is the 4MATIC+ AMG Night Edition Premium Plus and comes loaded with standard equipment. Twenty one inch AMG wheels, a muscular body kit, quad-tip exhaust, and a rear spoiler create a commanding presence, while instead features a panoramic roof, wireless charging, 360-degree camera, "transparent bonnet" tech, parking assist, and AMG Performance seats. 

The latest MBUX infotainment system, featuring an 11.9-inch touchscreen and 12.3-inch digital cluster, also features. 

For an extra £9,000, the "AMG Edition 1" ups the ante with a graphite grey paint job, yellow brake callipers, cross-spoke forged wheels, and a black and yellow interior theme with matching seat belts and floor mats. 

Both trims come equipped with an active anti-roll system, adaptive dampers and a wider track. Meanwhile, large brakes, with six-piston callipers at the front and four at the rear, are sure to provide ample stopping power.

Despite its plug-in hybrid status, the GLC 63 S prioritises performance over electric range. Its seven-mile electric-only mode is understandably limited given the focus on power. However, Mercedes claims a respectable 37.7mpg combined fuel economy and 170g/km CO2 emissions.
