Mercedes-Benz GLC-Class vs BMW X4

What's the difference?

The new Mercedes-Benz GLC200 might be the base-grade, but it doesn’t look or feel like it. From the outside, it’s stylish and refined, and inside, it delivers that signature Benz luxury with premium features, impressive tech and a beautiful cabin.

While the engine isn’t wildly powerful, it’s more than capable for everyday driving and long stretches on the highway and the ride quality overall is smooth, quiet and composed. It loses points for being more expensive than its entry-grade rivals and for those steep ongoing servicing costs, which could be a sticking point for some buyers.

Okay, so the BMW X4 xDrive30i is neither an ass nor an elbow, to be fair, it's more of a bulky shoulder muscle, or two.

I can't say I'll ever love the X4, the idea of it is a bit too weird for me, but I can't help admiring the way it looks and the way it drives.

It's a bit like a sedan on steroids - or an SUV on a diet, depending on your perspective - but that doesn’t take away from the fact that it’s fun to drive, comfortable and retains just enough coolness, and just enough practicality, to make it worthwhile.

The GLC is a handsome SUV with a strong, confident stance. It looks fit and premium, but not overly sporty, especially with the standard 'Avantgarde' exterior styling seen on our test car.

The entry-level grade rolls on 19-inch alloy wheels, features slimline running boards, LED lighting all around and an interior ambient lighting package that even includes logo 'puddle light' projection from the side mirrors.

Inside, the GLC200 doesn’t skimp on style. You get sports seats trimmed in synthetic leather (available in a range of colours), plus a panoramic sunroof, flashy dual displays and a black headliner that adds a cocooned feel.

The ambient lighting is a real standout and reminiscent of sci-fi films like Tron! It adds to the cabin’s upmarket vibe.

Combined with the soft-touch surfaces and neat trim details, the interior feels luxurious. And to be frank, it should at this level. But not every base-grade SUV in this segment gets it right. This one does.

So here's the thing. Obviously I have a personal beef with the existence of vehicles like this, but my eyes cannot deny the facts - the X4 looks fantastic. It's muscular, imposing and smooth all at once. Unlike the X6, a bigger and less visually successful attempt to play the same styling tricks with an X5, it doesn't have a ridiculous rear view that looks like it shoulders and buttocks have been fused (although it's hard to miss just how small the rear window is).

Even more impressively, there's no denying it looks better than the X3 that gave birth to it, so I can easily see why someone in a BMW showroom could be drawn to it. At least until they sit inside.

If the exterior style and eye-catching Sophisto Grey metallic paint don’t make an immediate impression then your eyes will surely widen at the interior, resplendent with bold Tacora Red seats, Aluminium Rhombicle trim finisher and the kind of sleek, classy styling that BMW excels in. 

Both the adjustable ambient lighting on the doors (we were partial to lilac) and door projectors that shot out what looked like robot wings onto the ground every time we hopped out of the X4 at night walked a fine line between futuristic cool and “parked out the front of a nightclub entrance” chintz, but over time the scales tipped more to the former. 

The big differentiator between the X4 and X3, of course, is the sloped coupé roof, a design feature that may make the X4 look a little cooler, but at the expense of cabin space, but more of that in a moment.

The cabin is spacious in both rows, with decent access thanks to wide door apertures and 195mm of ground clearance. That said, it’s the kind of cockpit you sort of tuck into and I knocked a knee or elbow on the steering wheel getting in (my husband joked this was just a user issue). My eight-year old had no trouble hopping in and out, though.

The front seats are best described as sumptuous, with features like expandable under-thigh and lumbar support. It’s super easy to get comfortable and stay that way, a big plus for anyone who does long drives, like I do.

The rear seats are equally comfy, with generous padding and deep bases. You’ll find three top-tether points in the back row, but realistically, it’s a space better suited to two child seats.

Keeping the cabin tidy is simple thanks to thoughtful storage throughout. There are deep door bins with drink bottle holders, a couple of cupholders in each row, a largish glove box and a dual-lid centre console.

Up front, there’s also a phone cubby, two USB-C ports and a wireless charging pad. In the rear, you get another two USB-C ports and some handy map pockets.

The boot has proven to be a practical space, with 620L of capacity and a level load floor. There’s a reversible mat and underfloor storage, which is also where you’ll find the space-saver spare tyre.

This grade now includes a powered tailgate, a welcome addition, and the second row folds electrically in a 40/20/40 split, giving you more flexibility when you need it.

The updated media display is easy enough to use once you spend a bit of time with it. The touchscreen is responsive, and wireless Apple CarPlay maintained a steady connection throughout our test. I also appreciated how the instrument cluster and head-up display pull through directions from either your phone or the in-built sat nav system.

For a car that is very much a mid-sized SUV on the outside, the interior can feel a bit too snug, like you’re driving a compact car that’s tried on a suit a few sizes too big (for reference, I’m 175cm tall - above-average height drivers may find the snugness soon turns to claustrophobia). 

While comfortable - it is BMW we’re talking about, after all - there’s not an overly abundant amount of headroom available, a feeling that becomes more pronounced should you shut the big moon roof.

My two children felt slightly too close to “you’re annoying me” distance from one another, which is to say this isn’t really the kind of car you should be getting if you plan on regularly ferrying about passengers in the rear who are bigger than a child. But I really don't think many people with kids would choose the X4 over the X3.

Boot space also takes a hit when compared to the X3 (550 litres versus 525-litres in the X4 - I was surprised the difference wasn't larger - although that expands to 1430-litres with the rear seats folded down. 

The boot opening is also mouth-shaped, which makes packing in wide-load items more of an issue.

Cupholders are plentiful - two in the front, two in the rear, and bottle holders in each door - and there’s a decent-sized storage cubby in between the front two seats. 

The sloped roof, and big fat A pillars, also result in the X4 being a bit more pinched at the rear, which is not especially great for visibility, with the vehicle’s blind spots taking some getting used to.

Cost-wise, the X4 is roughly in the same ballpark as the other cars in this strange sub-segment, but when you add in optional extras - metallic paint, panorama glass sunroof and BMW Laserlight headlights among them - the base price of $95,900 plus on-road costs sneaks up to $101,800, which is is no small figure. 

It’s also a considerable $8000 more than the SUV-shaped X3, meaning you’re essentially getting the same car, but with less cabin and boot space, for more money. To be fair, this is just part of a long tradition of the style-conscious buyer being willing to pay more for less, one that the invention of the coupe pretty much invented.

That kind of money also makes exclusions like adaptive cruise control, heated seats and wireless charging a bit of a head-scratcher.

Still, there’s plenty to love, including an M Sport kit that comes standard with the X4 (a suspension/brake package and various styling embellishments), butter-soft Tacora Red Vernasca leather seats (Sport adjustable for the driver and front passenger), 20-inch M light alloy double-spoked wheels, a head-up display, adaptive LED headlights, and an automatic tailgate. 

There’s also a generous high-resolution 12.3-inch control display and digital 12.3-inch instrument display, the former operated by touch or via the rotary iDrive Touch Controller. 

Cable-free Apple CarPlay and Android Auto are also available, but BMW allows you the option to use its iDrive system instead, just in case you're some kind of mad Munich fanboy - or you hate Apple. 

The GLC200 is powered by a 2.0-litre, four-cylinder, turbo-petrol engine paired with a 48-volt mild-hybrid system, producing up to 150kW of power and 320Nm of torque. It’s the least powerful engine in the GLC range, but still manages to feel punchy when you need it to.

This all-wheel-drive variant is paired with a nine-speed automatic transmission. While it can feel a little twitchy at lower speeds when the auto start/stop system is active, it’s otherwise a smooth and well-matched combination for everyday driving.

Now, prepare to be confused. In the past, the 3.0 in the xDrive3.0i nomenclature might have led you to believe you'd bought a BMW with a 3.0-litre straight six engine. But in this case, you have not, the 3.0 just means you have a more exciting version of the 2.0; a TwinPower turbo 2.0-litre inline four-cylinder engine, making 179kW and 353Nm that the xDrive system delivers to all four wheels. 

The claimed zero to 100km/h time of 4.9 seconds feels completely realistic as this engine has plenty of poke. Put it in the Sport setting and you'll get some serious shove. Indeed, the switch between Comfort and Sport is very noticeable and changes the character of the car entirely.

The transmission is an eight-speed conventional torque converter automatic gearbox that’s both smooth and responsive. 

The GLC200 has an official combined cycle (urban/extra-urban) fuel consumption figure of 7.5L/100km and with its 62-litre fuel tank, you’re looking at a theoretical driving range of up to 826km which are solid figures for a family cruiser.

In real-world testing, I averaged 7.8L/100km, mostly around town with one longer trip thrown in. Overall, I’m pretty happy with its efficiency.

Mercedes-Benz recommends a minimum of 95 RON premium unleaded petrol for this model.

The X4’s 65-litre tank needs to be 95-octane at a minimum, and BMW’s claimed combined fuel consumption is 7.9 litres per 100km. The temptation to use its rorty little engine is going to push you higher, though - you chose the one with the 3.0 badge on it after all - and we averaged 10.9 litres per 100km in our week together, which was mainly city driving, to be fair. 

Despite having the ‘baby’ engine in the range, the GLC200 doesn’t feel underpowered. Power delivery is generally quick, and there’s enough in reserve when you need to get up to speed or overtake. It’s responsive and confident in everyday driving.

That said, the auto start/stop feature is frustrating around town, especially at give way signs or roundabouts where you’re more likely to pause than come to a full stop.

It will cut the engine, and then when you want to accelerate, there’s a delay - sometimes even a little rollback. Not ideal, and definitely something that takes away from the otherwise polished drive.

The suspension hits a lovely balance, it’s forgiving but not floaty. You feel the road just enough to stay connected without it ever feeling harsh, which means the ride stays smooth and composed. It’s also a lovely highway cruiser, easily settling into long stretches with comfort and ease.

Visibility is solid, with minimal blind spots thanks to slim pillars, and the steering is responsive. It corners with confidence, too, with very little body roll, which isn’t always the case in a mid-size SUV.

Parking is straightforward thanks to a clear 360-degree camera system and park assist. The reversing camera turns with the steering wheel, which takes a moment to adjust to, but ultimately makes tight manoeuvres that little bit easier.

The impressive trick that BMW continually pulls off with its SUVs is giving them the same sensual, muscular steering as its sedans, and an impressively similar ride and handling balance.

The steering is the highlight here, but it's also noticeable how planted to the road it feels.

The X4 speaks to its looks, in fact, by feeling sportier and more alive to drive than you'd expect an X3 to be.  

This is less an SUV for soccer mums and dads, and more a bastard love-child that’s into loud leather and bright neon - a CEO who dressed punk rock-lite on weekends, if you will. 

If those weekends are bereft of child taxiing and loading up the boot with several tons of kid stuff, then you’ll have a blast in the X4. 

A 2018 test gave the X4 a five-star ANCAP safety rating, and an easily located button on the dash brings up the vehicle’s safety suite if you’re the kind of driver who likes to make a few adjustments. 

A 360-degree camera offers multiple viewpoints and is a godsend when parking the X4, since the cabin makes the car feel smaller than it actually is on the outside, and the range of safety features on offer are more than adequate. 

Those include autonomous emergency braking, dynamic braking lights, dynamic stability and traction control, rear-cross traffic alert, speed limit information and hill descent control. 

The GLC is backed by a five-year/unlimited kilometre warranty, which puts it on par with key rivals in this space. Servicing intervals are generous, too, at every 12 months or 25,000km. Great news if you rack up a lot of kilometres.

But the catch? Servicing costs are steep. Mercedes-Benz offers pre-paid servicing plans in three-, four-or five-year bundles, and the five-year package will set you back $7350. That averages out to almost $1500 per visit. Oof.

For comparison, the Audi Q5’s five-year plan is $3520, and BMW’s five-year 'Basic Service Inclusive' package for the X3 is $2475. So, while the GLC might win on features and finish, it definitely asks more of you when it comes to ongoing costs.

Despite all the brouhaha about other car manufacturers offering more generous warranty periods - seven years for Kia, for example - BMW has not shifted its stance, still offering its standard three-year unlimited-kilometre warranty. Frankly, it's just not good enough.

BMW also offer a Service Inclusive package for $2010 that covers owners for five years, or 80,000km.
