Mercedes-Benz GLC-Class VS Nissan Patrol

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 Patrol is a tried and tested 4WD, but it’s also an impressive open-road tourer. 

The auto is a smooth shifter and when you give the throttle firm and steady right-foot pressure the Patrol rumbles up to speed with an almost-lazy efficacy.

Ride and handling are nicely controlled and composed, on sealed surfaces and that’s carried over onto dirt – which I’ll get to soon. 

Its upright cabin stands tall, affording the driver ample visibility, and the Patrol’s expansive bonnet only impacts driver visibility when you head off-road – but more about that later.

The Patrol is refined and comfortable and yields a relaxed driving experience. 

It has independent suspension – double wishbones and coil springs at every corner – as well as the Nissan’s 'Hydraulic Body Motion Control' system, a network of hydraulic cylinders cross-linked between wheels, which works like a swaybar/swaybar disconnect.

This system automatically alters tension to suit the terrain (tightens on-road to keep the Patrol more controlled on firmer surfaces, such as blacktop; loosens off-road allowing for more flex in the suspension when you’re 4WDing).

Let’s not forget the V8. There's nothing like that growl as a backing track to whatever trip you’re doing and you've always got that throaty engine note as your own personal theme music. Just to put a bit of pep in your step.

It really is a beast of a thing and it is fun to drive. You might pay the price with fuel bills if you enjoy tapping that accelerator with gusto, but, geez, it's worth it. 

However, it’s when you get properly engaged in low-speed, low-range 4WDing that the Patrol is truly at home.

There’s no getting past the fact this Nissan wagon is a great touring platform and it’s also an impressive tow vehicle. There's no disputing those things, but it is a big vehicle and while it doesn’t feel as nimble as some other large SUV wagons, at least initially, it quickly becomes easier to drive the more time you spend in it.

It does take a little bit of getting used to if you haven't driven a Patrol before, but I have, many times, so it's quite comfortable and familiar to me. 

Steering has a nice feel and weight to it when you’re doing low-range four-wheel driving – and it’s when low-speed, low-range four-wheel driving is when you really need precision and the ability to laser-focus your driving lines. 

Throttle response is not touchy over bumps and sharp as long as you’re enthusiastic with it, and the auto transmission is just as cluey off-road as on. However, it can get caught out up hills, holding higher gears for too long, but otherwise it's okay.

There's an overall feeling of control to the Patrol. And again, while it is a large 4WD, it’s easy to drive well and to take on quite hardcore four-wheel driving terrain.

Drive with some consideration of its sheer physical dimensions and you’ll be fine. It’s comfortable and very capable; the result of a combination of traditional-style 4WD mechanicals, plenty of low-down torque and quietly effective driver-assist tech.

The Patrol Ti-L has selectable drive modes for off-road conditions and they include 'Snow', 'Sand' and 'Rock' and they tweak the traction control system, engine response and throttle with the aim of getting the Patrol to perform optimally on the chosen surface. 

It has full-time 4WD with high- and low-range and, while it doesn't have the low-down torque of something like the 300 Series, it has plenty of grunt when it counts. There’s ample torque for smooth-momentum 4WDing and the big petrol V8 keeps things ticking along without any stress.

Beyond the very effective off-road traction control system and the great low- and mid-range torque, you also have a rear diff lock. So if things get that difficult, you can always engage it. 

The Patrol has plenty of wheel travel, helped somewhat by its aforementioned swaybar-disconnect system, and that articulation helps it stretch a tyre to the dirt for all-important traction.

Off-road driver-assist tech (hill descent control, hill start assist etc) is non-intrusive and effective.

But it’s not all the best of news onboard the Patrol.

It feels quite low when you’re driving it over challenging terrain. Ground clearance is 273mm (compared to the 300 Series' 235mm) and approach, departure and rampover angles (28, 26.3, and 24.4 degrees) are par for the course for a large 4WD wagon with a wheelbase this lengthy.

But, while those measurements check out, that feeling of the Patrol being vulnerable to underbelly scrapes and knocks lingers.

Wading depth is listed as 700mm and, while I didn’t get the chance this time to test that limit (the usual mudholes were dry), I’ve driven through plenty of mudholes in this generation Patrol in the past.

As mentioned, the Patrol has an upright cabin, which offers plenty of visibility, but the expansive bonnet impacts the driver’s vision at the front, especially when driving over, for example, a steep crest into a dry creek bed.

As always, when faced with such a situation it’s best to get out of the vehicle and take a look.

The Patrol’s tyres – Bridgestone Dueler 693II all-terrains (265/70R18) – are perfectly reasonable on-road, but aren't well-suited to hardcore 4WDing.

As always with less-than-ideal off-roading rubber, if you're going to ask more of your Patrol than the occasional gentle drive along well-formed dirt tracks in dry weather, it's a good idea to replace the standard tyres with a decent set of aggressive all-terrain tyres. 

I've tow-tested with many Patrol variants over the years, so it’s worthwhile noting the towing capacities which are 750kg (unbraked) and 3500kg (braked), so standard for this size of 4WD.
