Jeep WRANGLER UNLIMITED VS Mercedes-Benz GLC-Class

The Wrangler Overland is a fun, go-kart style drive and yields a real driver-direct experience you get from few other contemporary vehicles on the blacktop and the dirt.

But while it’s nowhere near as atrocious as you might expect on sealed surfaces its planted, squared-off stance gives it a definite composure on bitumen. It’s certainly no sports car in terms of ride and handling.

It’s quite soft on-road, soaking up most imperfections with ease, but it also takes quite a lot of effort and concentration to keep this Jeep in line on the open road because it tends to float around on the blacktop if not constantly reined in. 

Also, its steering has a lightness about it that can sometimes be a bit disconcerting. 

The V6 is a gutsy unit, capable of punching the Overland along at a fair clip, all while the eight-speed auto handles clever and nicely controlled shifts.

Because it’s so blocky, straight up and down, with big wing mirrors and the like, the Overland is rather noisy on sealed surfaces.

But it remains one of the few modern vehicles that deserves to be driven with the windows down, because it offers that kind of visceral driving experience – as the LC70 Series, or Suzuki Jimny do.

So, how does the Overland perform off-road? Bloody glad you asked.

Spoiler alert: The Overland is not as good an off-roader as the Rubicon because it does not have that variant’s BFGoodrich Mud-Terrain tyres, 'Rock-Trac' active on-demand 4x4 system (with 4:1 transfer case*, and 77.2:1 crawl ratio), front and rear locking differentials, or the Rubicon’s very handy electronic front sway bar disconnect. (* The Overland has 2.72:1.)

But, having said that, the Overland is still an extremely capable off-roader.

To be honest, I wasn't expecting any strife because it retains all the traditional goodness of the Wrangler with very few compromises. It’s a genuine 4WD with a dual-range transfer case, a ladder chassis, solid axles and well-proven 4WD heritage.

In terms of size, the Overland is 4882mm long (with a 3008mm wheelbase), 1894mm wide, 1838mm high. It has a listed kerb weight of 1900kg.

Steering has a nice weight to it at lower speeds, giving the driver a great sense of sustained control through even the most severe obstacles, but the Overland’s turning circle is a listed 12.44m, so this off-roader can sometimes feel like a mini-bus to steer through tight turns.

However, this is a purpose-built off-roader with a wide wheel track and low centre of gravity, so it feels planted no matter how rough and bumpy the terrain gets.

On the gravel track to our off-road testing site, there are numerous steering-wheel-jolting corrugations but overall the Overland – with a coil spring at each corner – soaked them up.

Our 4WD loop included the aforementioned gravel tracks, light to medium corrugations, undulating mud tracks and mud holes, and some very challenging low-range 4WD sections (in particular, a steep rocky hill), and a few other set-pieces to see if the Overland was able to do everything safely and comfortably. 

As a true 4WD worth its weight in gold, the Wrangler is immediately more at home taking on low-speed 4WDing than it is negotiating suburban traffic.

Again, the V6 engine comes into its own, delivering smooth, even torque when needed, but not ever over-working to achieve that.

Considered driving is necessary as is slow and steady throttle, but that's easily achieved in the Wrangler as its go pedal is none too sensitive to a bouncing boot.

It’s refreshing to note that switching to 4WD High or 4WD Low range is still done via a stubby stick to the left of the auto shifter, rather than the push of a button, or the turn of a dial. 

Low-range gearing is very good and the Overland has a well-calibrated off-road traction control that seamlessly launches into action when required, and wasted wheelspin is kept to an absolute minimum.

This Wrangler has 242mm ground clearance and a standard wading depth of 760mm, and was never troubled on climbing steep rock steps, traversing deep ruts or punching through mudholes.

It’s supremely sure-footed during low-range work but visibility can be an issue: over-bonnet visibility has improved slightly over previous generations but the driver’s view to the front and side is still a bit squeezed, making it at times difficult to visually pick correct wheel-placement, especially when driving steep terrain at sharp angles.

It can go hardcore, no worries, but it simply requires a bit more thought and you know what? That’s fine with me because it makes the off-roading experience an even more engaging one. 

The Overland has approach, departure and breakover angles of 35.8, 31.2 and 20.4 degrees, respectively.

With live axles front and rear, the Overland has plenty of wheel travel to keep moving and under control through truly off-grid country.

The only real compromises in the Overland’s 4x4 set-up are its standard Bridgestone Dueler (255/70R18) highway tyres and, even on those, the Overland walked up and over our toughest off-road challenges.

Though the Overland is not historically regarded as a towing platform, it’s handy for you to know that it has listed towing capacities of 750kg (unbraked trailer) and 2495kg (braked).

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.
