Mazda CX-70 vs Toyota Tundra

What's the difference?

For mine, the CX-70 is the pick of Mazda's premium SUV range, and if you can survive without a third row of seats, it's significantly cheaper than its CX-90 twin, too.

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.

Yes, the Mazda premium SUV range can look a little same-same, but Mazda insists there are critical differences.

That said, if you can immediately spot the difference between the CX-70 and CX-90 without taking a peek inside, you're doing better than me, given it is the same exact dimensions as Mazda's three-row flagship.

Sure, Mazda talks about things like this design being a “passion pursuer” that serves up "dignified performance” – all of which sounds utterly ridiculous – but the less marketing-speak version is that it looks like a shapely large SUV that ditches the boxy dimensions of a proper 4WD for a more sleek and swooping profile.

Inside, it's a plush and premium-feeling space, with lovely cabin materials, plenty of tech, and plenty of space.

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.

The CX-70 measures a substantial 5120mm long, 1994mm wide, and 1745mm tall, and it rides on a 3120mm wheelbase.

It will tow 2.5 tonnes no matter which engine you choose, and the expansive boot will swallow between 589 litres and 2015 litres, depending on how you configure the backseat.

All of that space translates to a hugely airy backseat experience, with the second row able to be fixed in a position that either prioritises leg room or boot space.

With the former, you've got tons of space in the second row. I'm 175cm, and my knee and leg room was ample, with only the intrusive tunnel that runs down the middle-centre of the cabin eating into leg room for the middle passenger.

There are also air vents and temp controls, twin USB charge ports, seat heating in the window seats and swathes of very nice materials.

The boot is massive, too. I can't even reach the back of the rear seats when I lean into it, and Mazda says it will swallow smaller surfboard or SUPs without needing to resort to roof racks.

Under-floor storage adds a bit more security for precious items, too.

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.

You can have one of two engines in the CX-70, with the cheapest being a 3.3-litre, six-cylinder turbo-petrol, producing 254kW and 500Nm. There's also a 3.3-litre, six-cylinder turbo-diesel, making 187kW and 550Nm. Both are equipped with a 48-volt mild hybrid system to marginally reduce fuel use.

All models are AWD, and pair with an eight-speed automatic transmission.

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.

Petrol-powered cars will sip 8.1L/100km on the combined cycle, while the diesel drops that to 5.4 litres.

Both models get a 74-litre tank, meaning a theoretical driving range of around 900kms in the petrol, and almost 1400kms in the diesel.

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.

Interestingly, the CX-70 has been tagged as the expected smallest seller of Mazda's premium SUV range, but I reckon it just might be the pick of the bunch.

Every one of the CX-0 models (60, 70, 80 and 90) all get slightly different suspension tunes, and while you can find harsh edges in the other models, the CX-70 feels utterly composed and refined, at least on the smooth-ish roads of our launch test route.

Perhaps most surprising, though, is the CX-70's ability to hold its own on a properly twisting road. We expected lots of weight transfer and the high-pitched sounds of tyres screaming out in pain, but instead found Mazda's massive SUV served up grip, composure, and very little in the way of sea-swell-style body roll.

The two big six-cylinder engines also feel perfectly suited to a vehicle in this space. There's tons of power whenever you need it, and solid levels of refinement in terms of engine noise or diesel rattles.

For mine, the petrol engine is the pick though, feeing just a little smoother than the diesel option. The latter can feel a bit jerky at slower speeds, whether that's the power delivery or the gearbox, and it doesn't seem to happen with the petrol engine.

The biggest caveat, though, is that we haven't driven the CX-70 in its natural environment, the city and suburbs, so while it largely shone on flowing country roads, how it performs on roads like the ones near your place remains a bit of a mystery.

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.

Servicing is not particularly cheap in the CX-70, and the service intervals, at least in the diesel, feel a little short, too.

Buy that one, and you’ll be visiting the dealership every 12 months or 10,000kms, and the first five years of ownership will cost you $3298.

Petrol cars require servicing every 12 months or 15,000kms, and five years will set you back $3436.

The CX-70 is also covered by Mazda's five-year, unlimited-kilometre warranty.

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.
