Should you buy one? 

If we’re honest, no. While we appreciate the entertaining handling and straight-line performance, the whole plug-in system seems a bit pointless. Yes, it does emit a lot less CO2 than its V8 predecessor, but the real-world economy still isn’t good and neither is the sound it makes. 

If the old model appealed, you can still get a V8 super SUV for less than £100k in the Jaguar F-Pace SVR. Alternatively, the BMW X3M is a more focussed if less comfortable option, while you can discount the Porsche Macan, either. 

What we like  

The GLC 63 accelerates rapidly with launch control engaged and is a hoot in the bends when you’re really pressing on. Space is good for adults up front, equipment levels are pretty generous and it’s safe, too. 

What we don’t like 

The performance is too variable if you’re driving hard, and the engine just doesn’t sound that great. The boot is compromised by the hybrid system, and even then it’s barely more efficient than the old car in the real world. It’s also expensive yet feels cheap inside in places.
