Mercedes-Benz GLC estate front space
The GLC’s front seats slide back a very long way, so even seriously tall drivers won’t complain about the amount of leg room on offer. There’s plenty of front head room to accommodate anyone long in the body, too, although the optional panoramic glass does reduce this by a few centimetres.
Storage space is suitably generous with wide door pockets easily big enough to swallow a large bottle of water, while opening a lid on the centre console reveals two good-sized cupholders. The glovebox could be more capacious, mind.
Mercedes-Benz GLC estate rear space
Despite its relatively sporty styling, there’s plenty of space in the back to accommodate a couple of six-footers. Rear leg room is on a par with the rival BMW X3 and Audi Q5, and although rear head room is slightly less impressive (particularly if you’ve opted for a panoramic roof) only those long in the body are likely to be bothered by this.
As in many rivals, there’s a chunky transmission tunnel on the floor that a middle seat passenger has to straddle, so the GLC isn’t the best choice if you need to carry three adults in the back on a regular basis. Good-sized door pockets mean there’s enough space to stow a couple of small bottles of water.
Mercedes-Benz GLC estate seating flexibility
Folding down the GLC’s rear seats is really easy; you flick a switch in the boot (or another in the rear passenger compartment) and the seatbacks drop down automatically. The rear seatbacks also split 40/20/40, rather than the usual 60/40 arrangement, which means two rear passengers can enjoy full-size seats while you carry a long, narrow item.
The GLC isn’t available with sliding or reclining rear seats, but all versions have a fully electric front passenger seat including four-way lumbar adjustment.
Mercedes-Benz GLC estate boot space
The GLC’s boot is, officially at least, exactly the same size as a BMW X3’s. However, that doesn’t tell the whole story because the 550-litre figure includes some underfloor storage – the main load area is a fair bit shallower than the BMW’s, although similarly long and wide. The rival Audi Q5 and Land Rover Discovery also have bigger boots.
The GLC's load bay is widest at the very back of the car, which means you can slot in long, narrow items, such as a set of golf clubs, easily enough. Folding down the rear seats leaves a virtually flat extended load bay with no annoying steps or ridges.
All models come with powered tailgate, retaining nets on the boot floor and a lockable compartment under the floor itself.
