Infiniti QX30 vs Holden Trailblazer

What's the difference?

Even though it’s almost identical to the Q30, the QX30 manages to feel sufficiently different in suspension tune and cabin ambiance to be considered different.

It’s a disappointing oversight, though, by Infiniti to deny the base GT such basic safety fundamentals as a rear view camera (which Infiniti assures us is being worked on).

The Trailblazer is a solid all-rounder and deserves the consideration of those in the market for a decent seven-seater 4WD. It does everything well without ever really excelling at any one thing.

Is it fantastic? No. Is it a game-changer? No. Does it represent pretty good value for money in the grand scheme of things? Yep. 

The pick of the bunch for me is the LTZ – solid, off-road capable, and suburbs-friendly with just a hint of leather-appointed class. In the LTZ, you get everything worthwhile in the Trailblazer mob and if you’re a family man you won’t feel the need to fork out an extra $1000 for the Z71’s try-hard window dressing.

The Trailblazer is a mostly comfortable SUV wagon, stacked with features and is well worth your consideration if the Isuzu MU-X, Pajero Sport and Toyota Fortuner don’t float your boat.

The QX30 is one of the first projects to result from a technology partnership formed between the parent company of Mercedes-Benz and the Nissan-Renault Alliance.

In a sign of how worldly the car industry is becoming, the QX30 is built in Nissan’s Sunderland plant in the UK, using the German Mercedes-Benz A-Class platform and powertrains, all under Sino-French ownership via the Nissan-Renault Alliance.

On the outside, the design that first aired on the Q30 is pretty unique. It’s not a subtle car, with deep crease lines along its sides that, according to Infiniti, is an industry first in terms of manufacturing complexity.

When it comes to differences between the two vehicles, it’s minimal at best. There is a 35mm increase in height (30mm from taller springs and 5mm from roof rails), an extra 10mm in width, and extra trims affixed to the front and rear bumpers. Aside from the all-wheel-drive underpinnings, that is pretty much it for the exterior.

The same black plastic overfenders that are fitted to the Q30 are present on the QX30, with 18-inch rims on both the base model GT and the other variant, the Premium.

The dimensions of the QX30 are also an exact match for those on the Mercedes-Benz GLA, with the long front overhang acting as the main visual connection between the two cars.

The Trailblazer is a solid-looking wagon – all clean, tight lines from front to back – and overall it has a real squat and substantial presence. If we’re going to get all ‘fancy Dan’ with our hyperbole: chrome-accented daytime running headlights swoop back along the chunky body to slick LED tail-lights. If we’re sticking to basics: the Trailblazer looks good.

Inside, the tweaked interior has a tidy if rather basic feel to it – but that’s not a bad thing in a wagon that will have to cop dirt and dropped ice creams amid the general chaos of day-to-day life.

The leather-trim seats add a touch of class to otherwise family friendly dimensions and environment.

The QX30 is obviously very similar to the Q30 in many respects, but the interior is slightly different, with larger, less cosseting seats up front and slightly higher seats in the rear.

The cabin is also lighter in overall appearance, thanks to a paler colour palette.

There are plenty of neat inclusions, including a pair of USB ports, plenty of door storage, a space for six bottles and a sizable glove box.

A pair of cupholders resides up front, along with a pair in the fold-down armrest in the rear.

There is no particularly logical location for the storage of smartphones, though, and the lack of Apple CarPlay or Android Auto is down to Infiniti opting for its own phone connectivity suite.

A decent 430 litres of luggage space behind the rear seats is contrasted by a cramped rear area for all but the smallest of passengers, while sharply shaped rear door apertures making getting in and out a bit of an ask.

There are two ISOFIX baby seat points and a 12-volt socket in the rear, as well.

Climbing in is easy enough with a sturdy "overhead assist handle" for all comers and goers.

All of the Trailblazer’s seats are mostly comfortable except they are quite flat and hard, which may prove a hindrance over longer trips. The driver’s seat is six-way electrically-adjustable and there is little in the way of lumbar support.

The second row will better suit two passengers than three for long-distance comfort but there is enough room all round – head, shoulders and legs – to avoid most complaints, for a little while anyway.

Third-row passengers will need to be children or those of a shorter stature to cope with the ‘back of the bus’ squeeze – and even then trips should be kept to shorter distances to avoid an in-car riot. It’s not a terrible place to be, in the third row of this thing, but it’s not ideal either – pretty much in keeping with the rear-row offerings of its rivals.

Back up the front again and the dash design is clear, user-friendly and easy to get used to with day-in, day-out use.

There is a fair bit of storage space in the cabin but some of it is awkward to access and actually use. The glove box is big enough to cope with one or two handfuls of bits and pieces. There is a sunglass holder up near the rear-view mirror.

Passengers in the back also get air vents and manual aircon control.

There are two cup holders in front of the small centre console housing the USB port which, when used, eats into that available space.

All doors have a moulded bottle bulge, which wouldn’t cop our CarsGuide water bottle without forceful encouragement.

The second-row passengers get a fold-down centre arm-rest/cup holder when there’s no one sitting in the middle. Passengers in the back also get air vents and manual aircon control.

With all seats up, if you pack to the roof, there is 235 litres of cargo space at the very rear; with the 50/50 split-folding third-row seats folded down, there is 878 litres; with the second-row (60/40 split-fold and tumble) and the third-row seats down, there is 1830 litres of cargo space. There is a retractable cargo blind stowed away under the floor at the rear.

With the second-row seats folded forward, it is easy enough to get into the third-row seats; no contortionist moves required.

There are two 12-volt outlets in the centre dash; one at the back of the centre console (for second-row passengers); and one in the rear cargo area.

Up top, the roof rails are rated to carry 100kg.

The Trailblazer is available in three spec levels, each with a market-competitive price: base-spec LT (from $47,990, excluding on-road costs), LTZ (which we tested; from $52,490) and the limited-edition Z71 (from $53,490).

But those prices soon start to climb when you add in accessories such as all-weather floor mats ($130 for a pair), boot lip protector ($80) and a rigid cargo barrier ($960). Our test vehicle had a Power Blue (prestige paint) colour on the exterior, at a cost of $550.

All models have the 2.8-litre turbo-diesel engine and six-speed automatic transmission. The 4WD system is a dual-range part-time shift-on-the-fly set-up.

The LT’s standard features include cloth seat covers, 17-inch alloy wheels, a seven-inch touchscreen to go with its Holden MyLink infotainment system, Apple Car Play and Android Auto, Bluetooth connectivity, front fog lamps, signature daytime running lights, side steps, limited slip diff, rear parking sensors and a rear-view camera.

The LTZ gets all of that (although its touchscreen is eight inches) and more: integrated satnav, blind spot alert, forward collision alert and heated front seats and leather-appointed seat trim. It has 18-inch alloy wheels.

The Z71 has all of that gear as well as a distinctive sports look, replete with black bonnet, black mirrors, black exterior door handles, Z71 leather-appointed trim and 18-inch black alloy wheels.

Just the one engine is used across both cars; the 155kW/350Nm single-turbo 2.0-litre four-cylinder petrol engine from the Q30 and A-Class.

It’s backed by a seven-speed transmission and wired into an all-wheel-drive system that is biased towards a front-drive configuration.

Sourced from Mercedes-Benz, up to 50 per cent of drive can be sent to the rear wheels, according to Infiniti.

The 2.8-litre turbo-diesel engine punches out 147kW at 3600rpm and its big-gun 500Nm at 2000rpm and is well-matched to a six-speed automatic transmission. This Trailblazer is, on paper, a very good tow vehicle with so much torque available and from down so low.

Its towing capacity is 3000kg (braked), but I’d prefer to see how it fared in a real-world tow test before I pass judgement.

Infiniti claims a combined fuel economy figure of 8.9L/100km for the 1576kg QX30 across both the variants; this is 0.5L thirstier than the Q30 version.

Our brief test yielded a dash figure of 11.2L/100km over 150km.

Claimed fuel economy is 8.6L/100km (combined). We recorded 9.6L/100km fuel consumption after 200km of mixed driving, including about 30km of gravel tracks, and 10km of hard off-roading. As mentioned earlier, it has a 76-litre fuel tank.

Again, it would be easy to think that the QX30 would feel almost identical to its lower-riding sibling – but that would be incorrect. We criticised the Q30 for being a bit too buttoned down and unresponsive, but the QX30 feels more lively and involving, thanks to its unique spring and damper set-up.

Even though it’s 30mm higher than the Q, the QX doesn’t feel it at all, with a benign, pleasant ride with good body roll control and competent steering.

Our front-seat passenger complained of feeling a little ‘hemmed in’, which is a valid point. The sides of the car are very high, and the roofline is quite low, exacerbated by the steeply raked windscreen.

The 2.0-litre four-potter is smooth and punchy, and the gearbox well suited to it, but it’s lacking in aural character. Luckily the QX30 does a terrific job of suppressing noise before it gets into the cabin, then…

The LTZ is 4887mm long (with a 2845mm wheelbase), 1902mm wide (excl mirrors), and 1846mm high. It has a kerb weight of 2203kg.

Its turning circle is 12m but it feels like more of a cumbersome beast when trying to manoeuvre in the bush or in the city, though not enough so for that characteristic to be any sort of deal-breaker.

The tilt-adjustable, electrically assisted steering lacks any reach-adjustment, which is annoying, but it can still be counted on to deliver a precise feel – light at low speeds, heavier at high speeds – when pushing the Trailblazer along at a fair clip on open roads or in and out of corners.

Acceleration seems livelier now; there is more off-the-mark oomph for take-offs and safe, smooth overtaking, even on long gradual climbs, than before. The torquey engine and six-speed auto – with its smooth changes and gear-holding when appropriate – make for a high-achieving combo.

Ride and handling seem better than in Colorado7 guise although the tweaked suspension – Aussie-tuned coil-spring front and coil-spring live-axle rear – and Bridgestone Dueler H/Ts tyres* may account for some of that. However, we did feel some body-roll while driving along back roads, unlike the last time we were in a Trailblazer LTZ. (*The Trailblazer has a full-sized 18-inch spare.)

The locally tuned suspension is, at times, a bit too firm; when we hit heavy bumps and deep potholes on rough gravel tracks several times, we were unsettled because the Trailblazer’s suspension bashed its way over and through.

NVH levels on open-road bitumen can still tend towards the rougher side of things with diesel engine clatter, tyre roar and wind rush clattering a tune on your ear drums.

We completed a series of emergency braking scenarios – on bitumen and dirt – and the Trailblazer’s disc brakes – 300mm at the front and 318mm at the rear – helped rip us into a controlled stop.

Off-road, we had a ball because the beefy Trailblazer seems a much better fit for gravel-track fast blasts and slow-going bush driving than it does for any jaunts in the stop-start city.

Our drive loop included a decent bit of four-wheel driving – coastal sand, bush tracks peppered with rocks of all shapes and sizes, and shallow mud in a dried-out dam. Drive modes can be switched via the centre console dial between 2H, 4H and 4L; high range modes are actually represented by an ‘up’ arrow on the dial; low range is a ‘down’ arrow. Bonus: the Trailblazer’s 500Nm of torque is readily available from way down low.

The Trailblazer has a limited slip diff, 218mm of ground clearance and a wading depth of 600mm, which was never tested as our usual creek crossings were so bone-dry they were more like puddles. Approach, departure and ramp-over angles are 28, 25, 22 respectively.

Its armoury of off-road tech – auto hill-start assist, hill-descent control and more – make it almost unstoppable, straight out of the showroom, for anything demanded of it on a light- to medium-difficulty adventure weekend.

Its 76-litre fuel tank, however, hinders any claim it has to off-road touring potential.

The Trailblazer has 3000kg towing capacity (braked); 750kg unbraked.

Note: Holden has persisted with a system which, when you open a door, the front windows automatically slide down a bit, an action aimed at reducing air pressure when you close the doors. It remains annoying but we still weren’t annoyed enough to actually bother to check the owner’s manual for a possible hack to switch it off.

The Trailblazer range has a five-star ANCAP rating. The LTZ has seven airbags, and electronic stability control (ABS, EBD etc), rear view camera, front park assist, rear parking sensors, forward collision alert, blind-spot alert, lane-departure warning, rear cross-traffic alert, a tyre-pressure monitoring system and trailer sway control.

The second row has three child restraint anchor points and one ISOFIX child restraint anchor point.

The Q30 is offered with a four-year, 100,000km warranty, and servicing is suggested every 12 months or 25,000km.

Infiniti offers a fixed three-year service schedule, with the GT and the Premium both costing an average of $541 over the three services provided.

The Trailblazer comes with a three-year/100,000km warranty. Lifetime capped price servicing includes a free inspection at one month, then $299 (at nine months/15,000km), $399 (18 months/30,000km), $479 (27 months/45,000km), $479 (36 months/60,000km) and so on.

(At time of writing, the LT was being offered for $45,990 driveway with a seven-year/175,000 warranty.)

Potential problems might include cumulative driveline wear and tear from people towing heavy loads (horse floats, boats etc).
