Mercedes-Benz X250 vs BMW X Models

What's the difference?

The X was an opportunistic shot at a market segment new to Benz. With even apprentices able to afford to buy a well-specced Hilux, it's become harder to separate the foreman from the kids. I, like Mercedes, thought this would be the boss's car. Mercedes saw the gap and went for it, thinking it could grab sales from top end utes from VW, Toyota and Ford, while maybe saving a few folks from buying a RAM or an F150.

The problem is, the target market knows its utes. And in a rough-and-tumble workplace, the perception is that if you've spent up big on this Merc, you've actually just paid too much for a Nissan Navara. Still, like those flawed movies I enjoy, the X-Class is a fine thing - and I don't blame Mercedes for trying. It just costs too much, and yet isn't Mercedes enough to justify that price.

This is a highly competent all-rounder, given that it has the comfort and practicality for urban family duties yet with its revered M breeding can produce a level of performance which, in competent hands, could hold its own at a track day where its capabilities could be safely explored.

Despite being a Japanese ute in drag, the X-Class isn't immediately rumbled as resembling a Nissan, which certainly should count in its favour. Everyone who asked about it had little idea it wasn't a Daimler from the ground up, until you pointed out various details. Up here in the higher reaches, it's a really quality-looking thing, with beautiful paint and enough differentiation to make it look like a Merc. The headlights do seem a tad small next to the rest of the Mercedes range, but the whopping great three-pointed star in the grille leaves no one in doubt. 

It's fairly tasteful in silver, too, and with a few carefully chosen options it looks pretty tough.

Once you're inside you see where it starts to get confused about itself. The hard, scratchy plastic dash pokes out from behind a huge slab of metallic trim. The centre console is clearly a brother from another mother, as is the overall dash layout. The cabin lacks the thoughtfulness and quality of a Mercedes design - you can't just slap on those signature air vents and expect to get away with it. Every piece that comes from Mercedes appears glued on, and it's jarring. 

This might have been less of an issue if the car was significantly cheaper and not likely to be purchased by people who are familiar with the brand.

The fourth-gen X3, which has a lighter but stiffer body, shares the same wheelbase as its third-gen predecessor but at 4755mm end-to-end it's 34mm longer and it's 29mm wider.

It’s also 25mm lower, which combined with front and rear track-width increases and adaptive suspension damping to sharpen the handling underlines its sportiness and driver appeal, despite a substantial 2055kg kerb weight.

The new exterior design is characterised by short overhangs, flush door handles, a larger ‘split kidney’ grille, new LED taillights and L-shaped light elements for the LED headlights.

The new interior design is a classy mix of soft-touch materials and high-gloss hard surfaces in tastefully contrasting tones. The seats are upholstered in a new synthetic leather called 'Veganza' ('Espresso Brown' in our example) which according to BMW requires 85 per cent fewer CO2 emissions to produce than genuine leather (which is still available as an extra-cost option).

Combined with subtle use of ‘Magnolia’ fine-wood trim inserts, satin chrome, piano black, blue/red M highlights and slender ambient light-strips, it’s a cabin that exudes opulence.

I really can't imagine how anyone signed off on the most annoying features of the X. Front-seat passengers get a solitary, shallow cupholder (the second one is unusable), and big door bins that could hold a bottle if you didn't mind it getting smashed from sliding around (they're unlined), and nowhere to put your phone. Like, nowhere, except maybe the glove box. Even the centre console bin is shallow and not much good for anything, apart from as an armrest.

The front seats are reasonably comfortable but the rears are way too high (in the name of a better view) and rammed hard against the rear bulkhead. The rear doors are also pretty narrow, so entry and egress can be a bit of a challenge if you're large or toddler small. Once you're in the seats, legroom is limited and headroom marginal. At least you get air-conditioning vents, but you don't get an armrest in the rear. On a nearly $80,000 ute. Even the dark-ages Colorado has one of those.

Anyway, that's enough said about the interior flaws.

The tray is a big boy, but it's worth knowing that the roller cover does rob a bit of space, as it does on any ute. The optional tray liner looks good and with Mercedes-Benz stamped in it, reminds you again what you've got. All told, it's 1581mm long, 1560mm wide (1215mm between the wheelarches) and you can load up nearly a tonne of people and things into the X350. You can also tow a massive 3500kg braked and still be able to carry a payload of 490kg. Gross vehicle mass is 3250kg (tare is 2190kg).

This would make a great family weekend escape machine, for which BMW quotes a 645kg payload rating. It’s also rated to tow up to 2500kg of braked trailer, which could pose a challenge given the relatively low 100kg tow-ball download limit (TBD is typically around 10 per cent of trailer weight).

BMW also does not publish a GCM figure (how much it can legally carry and tow at the same time) so we can’t confirm if it can carry its maximum payload while towing its maximum trailer weight.

Even so, the M50 has a useful-sized luggage area which offers up to 570 litres (or 0.57 cubic metres) of load volume with the rear seat upright.

This expands to 1700 litres (or 1.7 cubic metres) with the rear seat folded flat, which can be handy for a multitude of tasks like transporting a mountain bike or hauling home flat-pack furniture.

There’s comfortable space for the driver and front passenger, along with useful storage including large bottle-holders and bins in each front door.

The centre console has two small-bottle/cupholders plus wireless phone-charging and a pair of USB ports. There's also a glove box plus another box at the rear of the console with a padded lid that doubles as an elbow rest.

The rear bench seat is surprisingly spacious, given that I’m 186cm tall and when seated behind the driver’s seat in my position I still have about 40mm of knee clearance, which is optimised by the concave shape of the front seat backrests.

The spacious and airy feel is enhanced by the ‘panorama’ glass roof which spans the full length of the seating area and allows generous headroom even for tall people.  

However, shoulder room is tight for three adults and the centre passenger’s feet must contend with the transmission tunnel, so even though it would be fine for three kids we’d suggest a limit of two adults for longer trips.

Rear passengers get privacy glass and pull-up roller sunshades, large-bottle holders and bins in each door plus net-type pockets and anchorage points for media devices on each front seat backrest. There are also two small-bottle/cupholders in the fold-down centre armrest.

The rear of the centre console has two USB ports, adjustable air-vents plus controls for zone temperature, airflow preferences and seat-heating.

The bench seat features a 40/20/40 split, which allows the centre backrest to fold forward independent of the two outer backrests to allow long loads like snow skis, home hardware etc to be carried if securely fastened.

A power tailgate provides access to the luggage area, which is equipped with a handy 12-volt accessory socket plus load-anchorage points front and rear, extra storage nooks for small items on either side and a retractable roller-type load cover. Overall, this vehicle offers good practicality for family duties.

Our X3 M50 xDrive test vehicle, finished in new 'Dune Grey Metallic', comes standard with a 3.0-litre turbocharged inline six-cylinder petrol engine incorporating 48-volt mild-hybrid technology, plus an eight-speed automatic and permanent all-wheel drive for a list price of $128,900.

You’d expect a high performance prestige vehicle costing six figures would be packed with desirable standard features and the M50 xDrive delivers, starting with big 21-inch 'M' lightweight alloy wheels shod with wide 285/35R21 tyres.

However, there’s no room for a spare (not even a space-saver) so you get a tyre repair kit instead.

The standard equipment list also includes adaptive LED headlights (with matrix high-beam and blue design detailing), a power tailgate, an ‘Iconic Glow’ illuminated kidney grille with M-specific elements, quad exhaust outlets, a panorama full-length (fixed) glass roof, a choice of six premium metallic paint colours and more. The 'M Sport Pro' visual enhancement package is also included.

Step inside and the driver is treated to a head-up display and an elegantly curved digital dash display, which spans about two-thirds of the cabin's width. It seamlessly incorporates a 12.3-inch driver’s instrument display (made from recycled polyester) and 14.9-inch multimedia display controlled by BMW’s latest 'iDrive System 9' software.

Premium audio is provided by a 15-speaker 750-watt Harman Kardon surround sound system, which includes digital radio and wireless Apple/Android connectivity. There’s also wireless phone charging.

The driver gets a thick leather-rimmed and heated 'M Sport' flat-bottom steering wheel and the driver and front passenger are also treated to sumptuous bucket seats with multiple power adjustments and heating/cooling.

Up to three passengers can share the rear bench seat and indulge in the luxury of three-zone automatic climate control, heating for the outer seating positions, privacy glass, roll-up sunshades, two USB-C ports and lots more.

The X350d has something very Mercedes about it - the engine and transmission package. With 3.5-litres of turbo-diesel V6, you get 190kW at 3400rpm and a thumping 550Nm between 1400 and 3200rpm. These kind of figures at least put it up there with the brawnier VW Amarok.

Feeding the power to all four wheels is Mercedes' own seven-speed automatic. A centre diff apportions power front to rear and you have a choice of three modes - automatic, high range and low-range.

According to BMW, the M50 xDrive features the most powerful inline six-cylinder petrol engine fitted to an M Performance model.

This 3.0-litre unit clearly benefits from BMW’s twin-scroll turbocharging technology, which combined with variable valve timing and an extra 13kW/200Nm from the 48V mild-hybrid technology produces a stomping 293kW of power at 5500rpm and 580Nm of torque at 1900rpm.

It also has a ‘boost’ function, which provides an extra burst of power for short periods when maximum acceleration is required when overtaking etc.

It’s activated by the left paddle-shifter on the steering wheel and automatically optimises transmission/chassis settings to suit. There’s also a drive mode selector, with ‘Sport’ offering the most responsive and engaging experience.

The eight-speed torque converter automatic is a refined and efficient transmission well suited to this full-time all-wheel drive application. Rapid-fire manual shifting is also available using the steering wheel paddles.

The X350d did pretty well in the week I had it - the official figure of 8.8L/100km was never going to happen but with a long motorway run to the Blue Mountains and the rest bashing about town, the 10.5L/100km I did achieve without trying was not bad at all. The 80-litre tank should give you a decent range of 750km, or thereabouts.

BMW claims an official average combined consumption of 8.2L/100km but the dash display was showing 9.9 at the completion of our 210km test, which included a mix of suburban, city and highway travel.

Our own figure, calculated from fuel bowser and tripmeter readings, came in slightly higher again at 10.5L/100km, which given our test vehicle’s two-tonne-plus weight and performance capabilities is still reasonable economy.

So, based on our figures, you could expect a realistic driving range of around 600km from its 65-litre tank, which prefers premium 98 RON petrol.

One of the weirder things to make it into the X-Class is the world's second most irritating column stalk, which is asked to pack in indicators, headlights and wipers. Thankfully, the world's most irritating column stalk, the Mercedes automatic shifter, wasn't inflicted on the X-Class. But the obvious problem is the key, which clearly isn't a Mercedes unit - even the star is ill-fitting and will probably fall off after a while. This is not a premium experience.

Thankfully, the big turbo-diesel wipes away a lot of the complaints about this car not being Mercedes enough. Brawny and super quiet (twin balance shafts will do that), the X is a very easy car to live with. While not especially lively, it's easygoing in the city and very refined.

On the open road it cruises almost silently and the ride is way above what you might expect from an unloaded tradie-mobile. It doesn't feel as high as some utes, which makes it feel a bit more car-like, and will no doubt appeal to some who might have to swap in and out of a traditional SUV and into the X, for whatever reason.

It is by far the most civilised ute I've ever driven and was worlds away from the Colorado I drove last week, to the point where I could almost - almost - see a justification for the unbelievably hefty price tag.

Credit for the refined ride and handling goes to the coil-spring rear end, much maligned in some quarters. While that style of suspension is not the ultimate in load-lugging, it's way more comfortable for passengers and, given the likely buyer profile, probably more agreeable than a cart-sprung rear-end.

I would cheerfully drive long distances in the X and it feels like it could go anywhere.

First, the fun stuff. It certainly feels like ‘the ultimate driving machine’ when you slide behind the chunky leather-rimmed flat-bottom steering wheel and hold it in your hands.

The driver’s seat offers not only powered adjustment of backrest and base-cushion rake, but also four-way lumbar support and side-bolsters that can tighten their embrace of your upper torso to contend with high cornering loads.

There’s also manual extension of the base-cushion length for greater thigh support and a big left footrest to brace against, so you could not ask for a more accommodating and purposeful driving position.

The steering is perfectly weighted and the quartet of enormous disc brakes provide ample bite with superb pedal feel. Combined with its adaptive suspension and wide grippy tyres, the X3 is a family car that’s also invigorating to drive, particularly when you select the ‘Sport’ mode.

The enhanced engine response and sharper steering that result (even the instrument panel display changes) make any twisting mountain road an engaging experience, enhanced by an intoxicating exhaust note that only a BMW M six can deliver.

The turbocharged engine offers an unyielding surge of acceleration from well below peak torque at 1900rpm to maximum power at 5500rpm, making BMW’s claim of 0-100km/h in a scant 4.6 seconds sound credible.

You can also manually change gears using the steering wheel paddles, but we found the gearing and shift calibrations so good that we preferred to leave it in auto mode.

However, the X3 M50 has two distinct personalities, as in more relaxed drive modes it’s just as happy serving as practical family transport during the week for grocery shopping, daily school runs and other common tasks.

It’s also a comfortable tourer for family getaways, with long gearing that requires only 1500rpm to cruise at 100km/h where low engine, tyre and wind noise allow highway conversations at lounge room levels.

No ANCAP rating as yet but this X3 comes with a long menu of standard safety features including multiple airbags, AEB with pedestrian/cyclist/junction detection, front collision warning with brake intervention, lane-keeping, active cruise control, head-up display with speed sign recognition, front and rear cross-traffic alert, tyre pressure monitoring and lots more.

There are also ISOFIX and top tethers for the two outer rear seating positions.

Mercedes offers a three year/200,000km warranty for the X, which isn't too bad. It also throws in roadside assist for the duration. Also worthy are the 12 month/20,000km service intervals. 

A basic capped-price service scheme will hit you for $1950 (pre-paid) or $2,555 if you pay when you front up for each of the three services covered. The servicing isn't super-cheap, as you can see, but at least you know what you're up for.

It comes standard with a five-year, unlimited km warranty.

Scheduled servicing is determined by BMW’s vehicle monitoring system which advises when a service is needed, typically around 12 months/15,000km.

A capped-price servicing package covering five years/80,000km (whichever occurs first) totals $2475, or an average of $495 per service.
