Holden Trailblazer VS GWM Tank 300

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.

I covered about 400km in total, on sealed surfaces in between off-road testing and overall the Tank 300 was rather impressive.

It’s quiet and refined on-road but has few alarming characteristics, which I’ll get to soon.

The petrol engine is lively and punches this 2106kg wagon along at a nice clip.

Steering has a sporty weight to it and is precise enough for easy driving in the city, suburbs and on the highway.

Ride and handling is nicely composed – mostly. It feels a bit floaty at times, some body-roll creeps in during livelier turns and there is a spongy feel to the coil-spring suspension.

But, other than that, this 4WD consistently feels stable and planted.

NVH (noise, vibration and harshness) levels are kept to a minimum, though there’s some wind rush around the chunky wing mirrors.

Visibility is reasonable but a bit pinched in places. The big bonnet can impact the driver’s forward vision, and that’s why, when you’re 4WDing, the Tank 300’s transparent chassis function comes in handy.

As for those 'alarming characteristics' I mentioned earlier…

Under heavy braking the Tank 300 pitches forward severely, with seemingly all momentum forcing the vehicle into a disconcerting nose-dive. Not good.

Driver-assist tech is generally seamless, but lane keep assist is too harsh and too pre-emptive in its application – wrenching you into line whenever it ‘thinks' you have drifted too far off-centre.

Auto stop-start engages abruptly and there is a disconcerting amount of lag before the vehicle starts again from standstill.

Not good at all when you need quick off-the-mark pace to safely merge with traffic from a stop light or after a lengthy pause at a roundabout.

The Tank 300 did however prove to be an effective off-roader. It handled the gravel track to our 4WD test site with ease.

This route is peppered with light corrugations, as well as, deeper into the bush, severe ruts and potholes, so it’s not an easy drive for any standard 4WD.

But this GWM wagon in 4WD high-range, did well, and was only ever rattled (a bit) when we hit a section of much deeper wheel ruts and potholes where modified 4WDs had damaged the track. 

My patented ‘Watch out for that 'roo!' emergency-braking test again revealed the Tank 300’s tendency to pitch forward dramatically under heavy braking and it took some work to keep the vehicle on track. 

The Tank 300 is well suited to low-range 4WDing. It may not have a ton of torque on tap (380Nm), but that pulling power is available across a decent rev range and this 4WD makes efficient use of what it does have.

Its off-road driving modes, including 'Mud/Sand', 'Rock', 'Mountain' and 'Pothole', seem calibrated appropriately for the demands of different terrain, although I wouldn’t rely on them, too much.

In the middle of an Aussie summer I didn’t get to test the ‘Snow’ setting, but when you engage some of the modes it will lock diffs where appropriate.

Low-range gearing is sound, without being Jeep Wrangler Rubicon great, and with its front and rear diffs locked, the Tank 300 tackled every 4WD challenge with ease.

Visibility is restricted in places due to the cabin build style, but that’s not such an issue when you’re 4WDing at very low speeds – you can always stop and get out of the vehicle to check the track ahead.

However, the Tank 300’s 'Transparent Chassis' function goes some of the way to improving driver visibility.

This system is similar to the 'Transparent Bonnet' view in the Land Rover Defender in that its aim is to extend the range of the around-view camera to include a view under the Tank 300 (represented on-screen as a ‘ghost vehicle’ outline when Transparent Chassis is selected).

Wheel travel is decent enough – the Tank 300 has a live rear axle – but the standard Michelin Primacy SUV tyres (265/60 R18) are not well suited to 4WDing. Fit a decent set of aggressive all-terrains to make this 4WD wagon even better off-road.

The Tank 300 loses a few off-road efficacy points, though, because…

It feels low. Ground clearance is listed as 224mm, and it has official approach and departure angles of 33 and 34 degrees, respectively (no ramp-over angle is listed), but it feels vulnerable to scraping its undercarriage on the earth.

Its pronounced side steps also seem to nudge the ground when you’re traversing rough terrain. Not among the Tank 300’s best features.

Listed payload is 446kg, which will quickly be used up once you add aftermarket equipment, passengers, camping gear and your dogs to the mix.

Unbraked towing capacity is listed as 750kg, while braked capacity is 2500kg.
