Mercedes-AMG GLC 43 4MATIC Coupe 2020 UK first drive

While Mercedes-AMG has had mixed form with its entry-level ’43’ performance models, we were impressed with the all-round balance of performance, luxury and comfort offered by the GLC version when we first tried it. And now, following a mid-life refresh for the whole GLC range, the GLC AMG version of the mid-size SUV has been given a makeover.

As with regular versions of the GLC, the revamped version of the performance SUV has been given a facelift including a new bespoke AMG grille and lights. But more significant is that it’s also been given more power, with fettling to the 3.0-litre V6 twin turbo lifting output to 385bhp from 362bhp previously.

Alongside that, AMG’s engineers have done a spot of fiddling with the rear-biased all-wheel-drive system and the chassis dynamics, with aim to boost agility. So does that extra engine output and minor fettling add to the driving experience, or upset the all-round balance that we've praised in the GLC 43 until now? 

We previously sampled the Mercedes-AMG GLC 43 in SUV form, but our first experience of this facelift version comes in the Coupe version. It's mechanically identical to the SUV version, albeit with a slightly less practical swooping roof line - and a higher price tag.

The AMG style tweaks, including the revamped grille, LED headlights, 20-inch AMG alloys, rear diffuser and twin tailpipes definitely add a subtle yet welcome note of differentiation to the regular GLC. 

The interior is as comfortably and spacious as you’d expect from a Mercedes SUV. While you wouldn’t call either particularly essential kit for an SUV, the sports seats are pleasantly enveloping and the flat-bottomed AMG steering wheel comfortable to hold. And, as with the non-AMG GLC models, the controls, 12.3-inch digital instrument cluster and 10.25-inch MBUX touchscreen are well laid out and easy to use.

But it’s the enhancements under the bonnet that most intrigue with this version. Mecedes-AMG says it has been able to add 23bhp to the engine output through a combination of software upgrades and a larger, standalone turbocharger - mounted closer to the engine to minimise response times. The nine-speed automatic gearbox remains, peak torque remains unchanged at 384lb ft, and the top speed stays at a limited 155mph.

That peak torque is available between 2500 and 4500rpm, and you can certainly feel its benefit from standstill. The V6 enables rapid progress from standstill, despite it shifting what remains a relatively hefty SUV.
