Mercedes-Benz GLC-Class VS Land Rover Discovery

Anyone who still believes in the adage ‘there’s no replacement for displacement’ hasn’t driven a modern turbocharged and hybridised engine. The GLC63 is a demonstration of the metaphorical and literal power of modern technology, combining an extremely efficient and potent internal combustion engine with an electric motor to make enormous real-world performance.

To be blunt, the GLC63 feels like a rocketship out of corners, launching with a ferocity and relentlessness the old V8 simply can’t match. It shouldn’t come as a surprise, a mid-size SUV with 1020Nm was always going to have plenty of performance, but even so it’s a shock to the system every time you give the GLC63 full throttle. Officially AMG claims it takes just 3.5 seconds to run 0-100km/h and has an electronically limited top speed of 275km/h - mighty impressive figures for a five-seat mid-size SUV.

To help get all that torque to the road, AMG deploys torque distribution technology that allows for it to be split an even 50/50 front/rear all the way to 100 per cent to the rear tyres.

Other technologies deployed to enhance its handling include AMG Ride Control suspension with adaptive damping and rear-axle steering. There’s also eight AMG Dynamic Select driving modes and four AMG Dynamics settings (Basic, Advanced, Pro and Master), so it’s a complex vehicle that is designed for the enthusiast.

While it’s easy to drive around town, once you get out on the open road you can really get a sense of the GLC63’s performance potential. Beyond just its powertrain the suspension offers good body control and the rear-axle steering helps it feel agile and responsive. 

It’s not perfect though. At times the complexity of the system does lead to some hesitation when you put your foot down. It certainly lacks the linear power delivery of the old V8 and makes for a slightly trickier driving experience at times.

As for the sound, which is one of the biggest elements missing from the V8, Mercedes has added AMG Real Performance Sound, which features a pressure sensor in the exhaust that picks up on the engine note and plays it through the speaker system. It certainly helps make for a louder, more noticeable engine noise, but it still sounds more like an A45 than the previous GLC63 and for many would-be buyers, that’s a major turn-off.

The Discovery is very impressive on-road. No surprise really as it has always had a reputation as a comfortable on-road cruiser – and it's lost nothing in this latest iteration. 

It is a smooth driving experience: quiet, refined and you suffer little to no noise from outside intruding into the cabin. 

The seats are very comfortable and supportive, and that makes it perfect for long-distance trips. 

The straight-six engine and eight speed auto are a nice combination, quietly effective, and well-managed. 

Acceleration is good with sharp throttle response, so you can crack on the pace when you need to, say, for instance, from a standing start or when you need to overtake a vehicle. 

In terms of overall driving experience, there’s nothing too outrageously exciting or dynamic on offer here, because this is a large SUV, but it’s always comfortable and it’s lively enough if you want to give it the boot. There are paddle shifters if you want to get fancy with your up- and down-shifting.

It’s not all good news: visibility from the driver’s seat is a bit pinched out the rear of the Discovery (due to its styling); there is pronounced body-roll through corners; the brakes are quite spongy, with a real delayed-action feel about them; ride is a tad harsh because you are rolling along on 20-inch tyres and rims, which is something I’m not so used to; and, the steering column is manually adjustable only, which I reckon is a bit slack for such a pricey vehicle.
