Like before, the engine is connected to a 48V mild-hybrid system, which incorporates an integrated starter-generator that produces a further 23bhp and 205Nm of torque. As well as extending the start-stop functionality, this set-up is also able to torque-fill the lower end of the rev-range to improve initial throttle response.
Power is then sent to all four wheels through AMG’s nine-speed automatic transmission. To keep everything in check, AMG has beefed up the drivetrain with new driveshafts and bigger brakes all round.

All GLE 63 S models feature air-suspension, with further support coming from an active anti-roll system. Models in most markets will be available with 21 and 22-inch wheel options, but only the latter will be available in the UK.
The newcomer’s other updates carry across from the revised GLE range. The more assertive nose features an even bigger grille, only now it has to compete for attention with the new headlights that integrate two star graphics inside them. The back includes the same black rear bar that now connects the lights, and the AMG’s typical oblong exhaust pipes and rear spoiler remain, too.
Inside, the remodelled dashboard and fresh user interface have been given the AMG treatment, with more figure-hugging seats and a new steering wheel. It might look similar to the previous car, but the two satellite controls that control the car’s dynamic functions have fresh displays and look sharper and are of a higher quality. There’s also the introduction of scroll wheels on the steering wheel’s upper spokes – much to the delight of existing Mercedes customers.
As before, the GLE 63 S will be available in an SUV or Coupé bodystyle, the latter having a more dynamic silhouette – and compromised rear headroom to go with it. A seven-seater GLS 63 will also be launched as well.
UK pricing has not yet been announced, but the GLE should cost around £140,000, especially given the tendency for Mercedes-Benz UK to only offer fully loaded variants of these high-performance flagships. The GLS will cost more like £160,000.
