The Mercedes-Benz GLC Took Its Time Arriving, Then Became Unstoppable

Both reviews frame this car the same way: a genuinely late entry into the mid-size SUV class that's since become Mercedes' best-selling model worldwide, now facing a second generation with real pressure to keep that momentum going.

Fashionably Late, Then Dominant

Being slow to enter a booming market segment usually costs a manufacturer dearly. Reviewers keep noting this badge somehow made up that lost ground entirely, turning a late arrival into its own best-selling nameplate.

Full Review Summary

What Car?

What Car? found the entry 220d diesel offers plenty of low-down pull without needing to be worked hard, while the ostensibly quicker 300 petrol doesn't feel as brisk in practice as its 0-62mph figure suggests. They praised the plug-in hybrid versions for more effortless power delivery thanks to instant electric torque, timing the 300e's 0-60mph at 6.4 seconds — quick enough to trouble some hot hatches. Visibility was rated behind the Audi Q5, BMW X3 and Lexus NX specifically due to steeply angled windscreen pillars, though the cabin's tall dashboard gives a more cocooning, premium feel as a trade-off.

Autocar

Autocar detailed a chassis that's 15% stiffer than the outgoing generation despite looking nearly identical from the outside, now built on a widened, 60mm-longer platform. They found the standard steel-sprung, UK-specification Sport suspension delivers rock-steady neutrality rather than outright dynamic thrills, noting the car handles predictably and gets power down effectively without breaking new ground for driver engagement. Their ideal specification — a 400d diesel on smaller wheels — isn't available in the UK, a genuine source of frustration given how well that combination reportedly suits the car's character.

Trims & Engines at a Glance

Every UK GLC gets 4Matic all-wheel drive as standard — the two plug-in hybrids use self-levelling air suspension at the rear, while every other engine sticks with conventional steel springs.

Derivative	Engine	Power	Transmission	Body	0–62mph
GLC 220d AMG Line	2.0L 4-cyl mild-hybrid diesel, AWD	197bhp	9-speed automatic	SUV	8.0s
GLC 300 4Matic AMG Line	2.0L 4-cyl mild-hybrid petrol, AWD	258bhp	9-speed automatic	SUV	6.2s
GLC 300e (PHEV) AMG Line Premium	2.0L petrol + electric motor, AWD	313bhp	9-speed automatic	SUV	6.7s
GLC 300de (PHEV diesel) AMG Line Premium	2.0L diesel + electric motor, AWD	336bhp	9-speed automatic	SUV	6.4s

Trim walk runs AMG Line → AMG Line Premium → AMG Line Premium Plus. The plug-in hybrids' 24.8kWh battery gives up to 80 miles of electric-only range. A broad exterior colour range is offered. Check Mercedes-Benz's UK configurator for current pricing.

Strengths

Broad, genuinely capable engine range including strong PHEVs
Stiffer, more composed chassis than the outgoing generation
Premium, cocooning cabin feel
Strong practicality relative to the smaller GLA and GLB

Weak points

Restricted visibility at junctions due to steep windscreen pillars
Petrol 300 doesn't feel as brisk as its on-paper figures suggest
UK buyers miss out on some engine and suspension combinations offered elsewhere
Handling prioritises composure over outright driver engagement

Who It Actually Suits

Buyers who want a genuinely practical, premium-feeling mid-size SUV and don't need class-leading driving thrills. The plug-in hybrid versions make particular sense for company car drivers chasing lower tax bands and more effortless everyday performance.
