The GLC 63 is now much quieter and more subdued in everyday driving compared to its predecessor. In Comfort mode, it can start in EV mode if the battery has enough charge, resulting in a noiseless and smooth acceleration as power is exclusively sent to the rear wheels.

When the software determines that hybrid mode is more appropriate, the engine starts and power is distributed to all four wheels via a nine-speed automatic gearbox and directly from the motor, providing a sense of urgency.

The PHEV system is undeniably effective. In Sport Plus mode, the GLC 63 is incredibly fast, even surpassing the old V8 in terms of 0-62mph acceleration.

However, it doesn’t always feel like a car with such high levels of power and torque. This is partly because the engine needs to reach 5250rpm for its maximum 402lb ft of torque and 6750rpm for its 469bhp, whereas the old V8 engine relied on its powerful low-end performance.

The car’s sound is not as assertive as before. It has a distinctive raspy exhaust note that becomes louder and more intense as you cycle through the different driving modes, and there are some acoustic theatrics on downshifts with pops and crackles, but it lacks the deep, bass-driven drama typically associated with AMG models.

On the plus side, the car offers significantly improved fuel efficiency. With an official fuel economy of 37.7mpg, it outperforms the old V8 by almost 16mpg, resulting in significantly lower CO2 emissions.
