Holden Colorado VS Foton Tunland

The Z71 has a steel ladder-frame chassis, double-wishbone front suspension and leaf-spring live rear axle, so it's more aligned with heavy-duty work than smooth on-road performance.

Having said that, the Z71 is quite settled over most surfaces, including highway bitumen and rough back-road backtop, and at most speeds – rather impressive for an unladen ute.

Steering is a bit floaty, with some play in it, and there is noticeable understeer on corners.

The engine is one of the torquiest in the current-day ute mob – only matched by V6 utes – and it delivers that torque quite evenly and smoothly across the rev range. The Duramax turbo-diesel can, however, be noisy, and because of that it seems like it's working hard, though it never feels too stressed, even when towing a caravan that has a caravan with a tare (empty) weight of 2600kg.

There's plenty of life in terms of acceleration with active pedal-feel but, when it comes time to pulling up to a fast stop on front disc and rear drum brakes, the brake pedals are rather spongy.

The six-speed auto is generally spot-on for all duties, although it did occasionally down-shift with an extra violence of action when it didn't really need to.

Ride and handling are pretty good, with its Aussie-tuned suspension (including traditional-ute leaf-springs at the rear) doing a decent job of sorting everything evenly, and it was only ever rattled by very severe bumps, wash-outs, and ruts at lower speeds, i.e. during low-range 4WDing.

The Z71's on-road performance and refinement are generally not as polished as segment leaders, but that's nowhere near a deal-breaker.

It’s a tight build free of rattles and squeaks, but the ride is too firm when empty or lightly loaded, particularly in the leaf-spring rear suspension which feels every small bump and delivers a sharp kick in your back over larger ones.

Otherwise, the chassis performance is more than adequate with its four-wheel disc brakes and steering that’s responsive and nicely weighted. Engine refinement and noise insulation are not best in class, but at highway speeds the combined engine, tyre and wind noise is certainly low enough to allow conversations without raised voices. The Cummins fairly lopes along here, with only 1800rpm at 100km/h and 2000rpm at 110km/h.

It’s also quite an agile and energetic performer around town, particularly in Sport mode. Maximum torque of 385Nm from the Cummins diesel is far from the strongest in this category, but the Tunland’s relatively low kerb weight helps to compensate for it with brisk getaways from standing starts and good throttle response in city and suburban driving. 

To test its GVM rating we strapped 770kg into the load tub, which with driver was only about 50kg short of its 925kg payload limit. The rear springs compressed 50mm while the nose rose 18mm. This resulted in a near-level ride height and noticeably improved ride quality, with no major decline in steering or braking response.  

With this load it was a competent performer on a variety of sealed and unsealed surfaces, including some bush tracks on which we engaged in both high and low range 4x4. Back on the bitumen, it also coped well with our two kilometre, 13 per cent gradient set climb, maintaining the 60km/h speed limit in third gear at 2250rpm all the way to the top. 

Engine braking on the way down, though, was compromised by the auto transmission’s unusual shift protocols. With second gear manually selected (in sequential shift mode) it over-rode that selection and shifted up to third when the engine reached 3250rpm on over-run. We tried it again several times and got the same result.

Not sure if it’s an engine protection measure on Foton’s part (redline is 4000rpm) but it’s not a nice surprise when you’re heavily loaded on a steep descent and relying on engine braking to help restrain your speed.

Our only other gripes were poor radio reception on the AM band (too bad if you like talkback) and the cruise control, which stopped working during our test and would not switch back on.
