The Mercedes GLC sits perfectly alongside rivals like the Audi Q5 and BMW X3, but the Jaguar F-Pace is a larger car, so has more room inside for passengers and luggage. Storage space in the GLC is plentiful enough, with a decent-sized glovebox, roomy door bins and nets in the boot. There’s also a handy cubby in between the front seats, and another ahead of the infotainment selector.

Size

The GLC measures in at 4,655mm in length, 1,890mm wide and 1,644mm tall. It's almost identical in size to the BMW X3.

Leg room, head room & passenger space

Rear seat space is pretty good, with plenty of head and legroom. There’s a rather large transmission tunnel thanks to the four-wheel drive system, but with large footwells, there’s enough room either side to spread out and get comfy. The centre seat is wide and soft too, so while an Audi Q5 is a more comfy car for two tall rear seat passengers, the GLC just edges things with three across the back. The high roofline means that headroom is plentiful.

Sitting in the Mercedes feels initially promising, with soft seats and plenty of adjustment. It’s hard to find a truly comfortable set-up, though, and we had to keep adjusting the settings. While the fully automatic GLC range means all cars only get two pedals in the driver's footwell, if you have big feet, you might find that your left foot rubs against the transmission tunnel next to the large brake pedal.

Boot

The GLC’s 550-litre boot capacity matches the latest Audi Q5’s, but both trail the Jaguar F-Pace by 100 litres. Still, the Mercedes gets a power tailgate and electronic remote releases for the folding rear seats, plus there’s more underfloor storage to tuck things out of sight.

Fold down the standard-fit 40:20:40 split-fold rear seats and you’ll reveal a 1,600 litre boot – which is identical to an X3. Storage is good, too, with plenty of cubbies and trays.
