BMW XM vs Toyota Tundra

What's the difference?

It’s pretty obvious the XM is designed to impress people with big wallets and an appetite for a techy experience that’s also not without a few green credentials. The ability to motor around as a fully-electric vehicle for up to 80km or so is a big plus and the electric-ballroom interior vibe is hard to ignore, as well.

But from our perspective, the full-fat, twin-turbo V8, while offering startling performance, is perhaps a lost opportunity to follow some of BMW’s competitors into the engine-downsizing space. Then again, when you floor the throttle and 2700kg hurtles forward like a big dog on a short chain, you can see where BMW is coming from.

Perhaps the biggest letdown is the ride quality – or lack of it. While it’s understandable BMW wanted the most dynamic version of the XM it could manage, the end result plays against the vehicle’s otherwise long suit of hyper-luxury. Doubtless, BMW would argue that to soften the chassis would have been to introduce a chink into a no-compromise product. But, perhaps, sometimes a sensible compromise is the way forward.

The Tundra Platinum is a good-looking and well-engineered RHD full-size US pickup which stands apart from local competitors with its unique hybrid drivetrain and unmatched power/torque outputs. However, it also comes with a conspicuously high purchase price, which given the quality of local Ram, Chevrolet and Ford competition could be a deal-breaker for some.

There’s nothing subtle about the way the XM looks. It probably pulls up just short of brutalist (or maybe not) but even those who find its slabs and angles attractive have to admit that it’s bold.

The now-trademark giant nostrils set the mood and the rest of the exterior suggests some kind of armoured transport for presidents rather than wheels for the school run. Doubtless, this will hardly be seen as a fault by those in the market for such a thing.

The real surprise here is that the XM does not share a bodyshell with any other production BMW. Sure, the V8 petrol engine and wheelbase are common to other BMW and M models, but the sheet metal is the XM’s and the XM’s alone. That in itself, is quite a statement of intent.

This is a substantial vehicle with bold, bluff-fronted styling characterised by an enormous grille that has an imposing presence wherever it roams.

Toyota's TNGA-F ladder-frame chassis platform is shared with the LandCruiser 300 Series and Prado models, but the big American has a much longer 3700mm wheelbase, spans almost six metres in length (5955mm) and is more than two metres wide (2040mm). However, it’s less than two metres tall (1985mm), so it can access underground and multi-storey carparks. 

It rides on double-wishbone coil-spring front suspension and a multi-link coil-spring live rear axle, with electric power-assisted rack and pinion steering and big four-wheel disc brakes.

Off-road credentials include 216mm of ground clearance, 23 degrees approach and 21 degrees departure angles – which are ample for accessing rugged worksites – while the turning circle is an expansive 15 metres.

The interior, with its panoramic sunroof, has a spacious and airy ambience, enhanced by contrasting blue stitching on its leather-appointed upholstery.

Although the cabin has a high standard of fit and finish, as you’d expect from Toyota and WAG, it doesn't look and feel quite as lavish as the sumptuous interiors found in its top-shelf US rivals. The centre console lid in particular feels too light and plasticky for a vehicle in this price range.

Given the vast exterior dimensions and a weighbridge ticket the wrong side of 2700kg, it may come as a surprise to learn that the XM is strictly a five-seater with not even an optional third row.

That said, the uber-SUV Lexus LX in flagship, Ultra Luxury, trim offers just four seats in deference to the VIP clientele it’s pitched at, but also comes complete with reclining rear seats and a passenger’s side footrest which the XM can’t match.

Staying in the rear seat, there’s lots of legroom and plenty of space under the front chairs for feet. A lot of that is down to the wheelbase the XM shares with the BMW X7, and even behind a tall driver, there’s lots of space. In fact, compared with a BMW X5, there’s a full 150mm of extra legroom.

The pew itself flows into the door trims for a lounge effect which looks great with the contrasting light-coloured trim, and the centre arm-rest folds down to reveal a pair of cupholders. Extra storage space can be found in fold-out pockets in the rear of each front seat which also house a small, lidded panel that opens to reveal USB ports and power sockets. Dual-zone climate controls are also part of the rear-seat experience.

The gee-whizz stuff hasn’t been ignored, either, and the prismatic roof lining is nothing if not a talking point. But would a panoramic sunroof have been of more value to many buyers? The ambient lighting is a nice touch, too.

Up front, the view is dominated by the giant, twin curved animated dashboards. They deliver information and lots of it, to the point where it can almost seem a bit overwhelming.

The head-up display helps simplify things, but there’s absolutely no doubt there’s a lot going on in this cabin. Again, this is modern luxury motoring, but it remains that the menu system will take time to learn, even if the touchscreen function gives you an option on how you control things.

Multi-adjustable front seats are part of the deal and there’s an M-spec steering wheel which is heated. And although it features plenty of buttons, isn’t as daunting perhaps as the multi-spoked equivalent in some high-end AMGs of late.

The stereo system is also worthy of a mention, being a Bowers & Wilkins unit with roof mounted speakers and no less than 1500 watts of power. Digital radio is part of the package.

Even though it doesn’t offer a seven-seat option, luggage space in the rear of the XM is hardly class-leading. Cargo volume with rear seat up is 527L and 1820L with it folded.

Much of the wheelbase is devoted to rear-seat stretching room and although the batteries for the electric motor are positioned under the rear seat, the floor of the cargo area seems quite high.

With its 2834kg kerb weight and 3536kg GVM, the Platinum has a 702kg payload limit which is modest compared to smaller 4x4 utes with genuine one-tonne-plus capabilities.

However, it’s rated to tow up to 4500kg of braked trailer on a 70mm ball and with its substantial 7980kg GCM (or how much weight it can legally carry and tow at the same time) that would require only a small drop in payload from 702kg to 646kg to avoid exceeding the GCM. So, that’s a practical set of numbers if you ever need to tow the maximum 4.5 tonnes.

The load tub is 1660mm long, 1491mm wide and 531mm deep, with 1237mm between its rear wheel-housings allowing either a standard Aussie or Euro pallet. It’s accessed through a power tailgate, which can be operated from the driver’s seat if required.

The tub’s internal surfaces are protected by a composite drop-in liner, with handy slots moulded into each side for vertically inserting planks of wood to serve as lateral load-dividers if required.

The Platinum's tub also has unique hooded LED lighting in each sidewall, plus there’s fixed load-anchorage points front and rear at mid-height (would be better if just above floor height) and rails with adjustable sliding anchorages along the top of the front and side walls for securing taller loads.

Cabin storage includes two 600mL bottle-holders and storage bins in each front door plus a decent-sized single glovebox, a 12V dash socket and an overhead glasses-holder.

The centre console offers open storage up front including a wireless phone-charging pad, plus a pair of small-bottle/cupholders in the centre and a large lidded box at the back containing USB ports.

The large rear doors, with pull-up privacy screens on their windows, provide wide entry to the rear bench seat. There’s enough shoulder room for three adults and even tall passengers enjoy ample legroom, although those seats in the centre must contend with a transmission hump, which is absent in its flat-floored rivals.

There’s two 600mL bottle-holders and a bin in each rear door, plus large pockets on each front seat backrest and two more bottle/cupholders at the rear of the centre console, which also has controls for rear seat heating/cooling, plus USB ports and adjustable air-vents.

If travelling with two, the centre seat backrest folds down to provide a comfortable armrest and two more bottle/cupholders (that's 14 in total), so drink storage is well catered for in this cabin.

The rear seat’s 60/40-split base cushions can also swing up and be stored vertically for more internal luggage space, but there’s no storage compartments underneath as this space is occupied by the hybrid drivetrain’s battery, with large vents on either side providing it with ample ventilation.

Our only criticism of the rear seating is limited headroom for tall people, caused by a deep contour in the roof-lining to accommodate the Platinum’s sunroof.

This contour sits very close to foreheads and limits head space. So, if you have tall passengers, they might get cranky on long drives, particularly those seated in the slightly higher centre position with (like me) the top of their head pressed firmly into the roof lining.

Our recently launched Platinum test vehicle is, like its Limited sibling, available only with Toyota’s ‘i-FORCE MAX’ hybrid powertrain, which combines a 3.5-litre twin-turbo V6 petrol engine, electric motor-generator, traction battery and 10-speed automatic transmission, for a list price of $172,990 plus on-road costs.

That pricing is $17,000 more than the Limited and considerably higher than Australian premium-grade RHD rivals including the Ford F-150 Lariat LWB ($140,945), Chevrolet Silverado 1500 ZR2 ($141,500) and Ram 1500 Limited ($159,950). Note the F-150 has temporarily been withdrawn from sale in Australia due to an ADR compliance issue.

The Tundra Platinum shares numerous standard features with the Limited, including 20-inch alloy wheels (although the Platinum’s wheel design is unique) with 265/60R20 tyres and a 245/75R18 ‘space saver’ spare (to optimise its underfloor-mounted ground clearance), LED lighting, heated door mirrors, an automatic ‘active’ front spoiler, side steps, a power tailgate, a tub liner, a 3500kg towing kit and front/rear parking sensors to name a few.

The cabin has smart entry/start, dual-zone climate, front seat heating/cooling, a leather-accented steering wheel and shifter, a 12.3-inch driver’s digital instrument cluster, a 12-speaker JBL audio system with a 14-inch multimedia touchscreen and multiple connectivity including Apple/Android devices, wireless phone charging, power sliding rear glass, five USB ports and more.

The Platinum adds not only its unique black-painted alloy wheels but also a bold mesh grille design with dark chrome surround, black body detailing, tailgate spoiler and rain-sensing wipers.

The cabin gets a full-length panoramic sunroof and leather-accented trim, with the front seats equipped with 10-way power adjustment including a massage function. There’s also heating/cooling for the outer rear seats, heated steering wheel with power tilt-reach adjustment and 10.9-inch colour head-up display.

Here’s where the XM starts to justify its price-tag. While the use of an electric motor to boost a petrol engine has allowed some manufacturers to reduce the capacity of the latter, no such restraint has been shown for the XM. Instead, it gets the full 4.4-litre, twice turbocharged V8 that we’ve come to know and love from this brand.

It’s not that this is the engine’s first date with hybrid technology, but the mild hybrids that have come before it can’t match the XM for sheer brutality when both power units are unleashed.

The petrol V8 can muster up 360kW and 650Nm which, when boosted by the electric motor, jumps to a total of 480kW (combined) and 800Nm.

While the petrol engine drives through an eight-speed torque-converter automatic, the electric motor also drives through the transmission, an arrangement that is a bit different to some hybrids which use the petrol engine for the rear axle and the electric motor to drive the front wheels.

Of course, the requirement for the XM to feature permanent all-wheel drive, regardless of what power unit is running at the time, forces this layout.

Speaking of all-wheel drive, The XM’s version of BMW’s 'xDrive' layout has been specifically tuned for this vehicle and includes torque vectoring as well as a limited-slip rear differential.

The system has the ability to vary the torque split front to rear, with the default rear-bias giving a more sporting feel on good surfaces. An active rear differential also helps give the car a rear-drive feel.

As well as modes for 'Hybrid', 'Electric' and 'eControl' modes, the XM sticks with the M tradition of offering two M buttons which can be configured to set the parameters for steering, driveline, chassis and, in the case of the hybrid XM, the degree of braking regeneration offered.

Four-wheel steering is also part of the XM’s repertoire and, interestingly, there’s no air suspension here; just conventional steel springs.

But it does feature an electrically-adjusted anti-roll bar system which aims to strike a happy medium between what the driver wants and the road conditions demand.

The Tundra’s powertrain consists of a 3.5-litre twin-turbocharged V6 petrol engine that produces 290kW of power at 5200rpm and 649Nm of torque between 2400-3600rpm.

This is paired with an electric motor mounted directly behind, which produces 36kW/250Nm and draws its electrons from a 6.5Ahr Ni-MH (nickel metal hydride) battery located beneath the rear seat.

Their combined output is 326kW and 790Nm, which is more power and torque than any of its local rivals and therefore appealing for those who need to haul and/or tow heavy loads.

Its refined 10-speed torque converter automatic offers the choice of sequential manual-shifting, a dedicated Tow/Haul setting and three drive modes comprising Normal (default), Sport and Eco.

The 4WD system is part-time, dual-range with 2H (2WD High Range), 4H (4WD High Range) and 4L (4WD Low Range). There’s also an automatic limited-slip rear differential, but unlike its competitors no full-time AWD mode is available.

A 25.7kWh lithium-ion battery provides the power for the electric drive. It’s mounted under the rear seat and can produce a purely electric range of between 82 and 88km (based on WLPT test protocols).

Charge time from a conventional wall-box is said to be about four hours but, interestingly, the XM has no provision for DC fast-charging.

Fuel consumption (combined cycle) is an EV-typical 2.7 litres per 100km, which equates to a low 61g/km of CO2.

Once you’ve depleted the battery on a highway journey, expect the petrol V8 to consumer somewhere between eight and nine litres per 100km at cruising speed.

Using EV mode means zero-emission operation but, as with any electric car, how the power is generated to recharge it determines its real-world green-ness.

With the Tundra’s GVM rating exceeding 3.5 tonnes, Toyota is not required under current ADRs to publish fuel consumption figures. Even so, we covered a total distance of 298km, which comprised a mix of suburban, city and highway driving of which about one third was hauling a near-maximum payload.

When we stopped to refuel, the dash display was claiming average combined consumption of 14.1L/100km, but our own figure calculated from fuel bowser and tripmeter readings was 15.8, which is in the same ballpark as mid-teen figures we’ve achieved in its six and eight-cylinder rivals.

Therefore, based on our own figure, the Tundra Platinum has a real-world driving range nudging 800km from its big 122-litre tank, which according to Toyota requires minimum 95 RON petrol.

While any M car is supposed to be rapid and dynamic, it’s also true that the over-arching perception of big SUVs is that they’re comfortable and plush. None of which explains the ride in the XM.

Regardless of how you fiddle with the settings, the ride is always brittle. Those big tyres with their minimal sidewall somehow manage to find every crack and join in the road, and it’s these sharp-edged imperfections that thump through to the cabin the most vocally.

It’s enough to make you wonder who this car is going to appeal to. Will it take to race tracks? Almost certainly not. So the whole point of these suspension settings might be a bit lost on some people.

Performance, meanwhile, is insanely rapid for something that could pass as a bulk carrier. The biggest giveaway to the mass is the transmission’s earnest attempts to keep everything moving by feeling a bit hyperactive on downshifts.

Using the ratios is always going to be the strategy, but with all that torque, maybe it’d be nice sometimes for the trans to hang on to a taller gear and let the boost blow it towards the next corner.

The sound track? Polarising. Even if it doesn’t convince you that Hans Zimmer (who developed the various electronically-synthesised noises the XM makes) should stick to winning Oscars, the augmented sounds are background noise rather than the main event here.

Even the petrol V8’s naturally stirring backing vocals have been electronically tweaked with debatable results.

That said, it’s nice to have something to listen to that isn’t the insistent tyre roar which becomes even louder on coarse-chip surfaces.

Steering effort is light but there’s not a lot of feedback in terms of actual feel. In fact, it’s borderline detached and only the sheer speed of the rack confers any athleticism.

Also, the rear steering seems to come in a few milli-seconds after the front has started to turn. And for all that all-wheel-steering agility, this is never a car that shrinks around you.

The side steps are set close to the sills and, therefore, a bit narrow for size 12 boots, but big handles on the A and B pillars assist climbing aboard, where you’re rewarded with a spacious driving position with multiple adjustments.

The analogue-flavoured RHD dash module has numerous physical dials, buttons and switches, which thankfully leaves minimal reliance on distracting touchscreen prompts. Some items, like the left-hand-side indicator stalk and HVAC controls, are biased towards LHD, but you soon get used to these idiosyncrasies.

Its excellent steering feel, braking response, supple but responsive four-coil ride quality and effective noise insulation are what we’ve come to expect from WAG’s extensive remanufacturing process. In the Tundra’s case, it uses many original equipment components from existing Toyota 4WD vehicles and OEM suppliers.

The V6 engine produces a meaty V8-style soundtrack, with a melodic throb at idle and a guttural roar at full throttle. From standing starts, the abundant torque gets more than 2.8 tonnes of pickup to triple-digit speeds in about six seconds, which is comparable to Ford's sporty Ranger Raptor.

The hybrid drivetrain displays excellent refinement, as it continuously and seamlessly switches between petrol and electric power to optimise performance and economy. The Tundra is also an effortless highway cruiser, with negligible tyre and wind noise at 110km/h allowing conversations at loungeroom levels.

To test its load-hauling ability we strapped just over 500kg into the load tub, which with our two-man crew equalled a total payload of 675kg that was nudging its GVM limit. The coil-spring rear suspension only compressed 50mm, leaving ample bump-stop clearance and no risk of bottoming-out on our test route.

It made light work of hauling this payload in city and suburban driving and didn’t seem to notice it had anything in the load tub on our 13 per cent gradient, 2.0km set-climb at 60km/h.

Engine-braking on the way down, in a manually-selected second gear, wasn’t as robust as expected given the assistance of regenerative braking, but the large four-wheel disc brakes were more than capable of keeping speeds under 60km/h when called upon during the descent.

Like its local US competitors, the RHD Tundra does not have an ANCAP rating but comes with a suite of passive and active safety features. These include eight airbags, AEB with day cyclist detection and day/night pedestrian/oncoming vehicle detection, lane-keeping, trailer sway control, trailer back-up guide with straight path assist (makes reversing a trailer easy and safe), blind-spot monitoring, rear cross-traffic alert, front/rear parking sensors, panoramic view monitor and more. The rear seat has two ISOFIX and two top-tether child-seat anchorages.

Like a lot of manufacturers, BMW knows consumers can be leery of EV tech when it comes to the cost of battery replacement. So, as well as the five-year/unlimited-kilometre warranty on the whole vehicle, there’s also eight years or 160,000km of cover for the high-voltage battery.

Servicing intervals are based on how the car has been used and it will inform the owner when a service is required.

A servicing package is included in the purchase price and BMW even throws in three years of roadside assistance.

The Tundra comes with Toyota’s five-year/unlimited-kilometre warranty, which is class-leading.

Scheduled servicing is six months/10,000km whichever occurs first, with capped-pricing of $450 per service for the first five years/100,000km. So, that’s $900 annually, if serviced twice a year as scheduled.

Toyota currently has 275 dealers across its vast network located in metro, rural and regional areas. Toyota dealerships are also service centres.
