Mazda BT-50 VS Holden Colorado

While the BT-50’s main rival, Ford’s Ranger (and the related VW Amarok), is often considered the class leader in road manners, the Thunder Pro’s Old Man Emu BP-51 suspension upgrade is a game-changer for the ute.

Even on particularly rough roads with brutal unexpected waterlogged potholes, the BT-50’s OME set-up managed to keep the ute on track and settled without letting crashy vibrations and forces enter the cabin too acutely.

Of course, the BT-50 is still a ladder-frame ute, and combining that with torrential rain in the middle of almost-nowhere isn't the right combination when it comes to leaning on a dual-cab’s dynamic ability.

But the braking and steering in the BT-50 are impressive for its category, both feeling well-sorted: the former firm and strong when needing to stop quickly, the latter light but communicative enough for purpose.

The Mazda doesn't feel too top-heavy in cornering, no wild pitching or rolling here. Stable on gravel, too, feeling sure-footed and only intervening with active stability control when necessary and in a measured way. 

With just little old me and some overnight luggage, the BT-50’s engine wasn’t exactly pushed to its limits hauling the 2.2-tonne-plus ute up the Hume Highway at 110km/h. But even on twistier roads and under load up hills it never felt lacking.

Though not on this test, we’ve also tested the BT-50 under load and towing, both proving easy tasks for the ute.

Mostly low-RPM work and cruising contributed to its fairly efficient fuel figure mentioned above, but putting the right foot down a few times confirmed the 3.0-litre turbo-diesel has some decent muscle if needed.

Finally, and very much worth noting if the Pro Pack is why you’re reading this, the combination of Lightforce LED light bar and twin-spotlights is a must if you regularly drive at night through unlit regions of Australia.

As someone who grew up driving 4WDs with spotlights at night on interstate trips, the lights fitted to the Thunder Pro are impressive in their illumination, combining relatively wide light - perfect for ensuring you’re not caught out by surprise wildlife crossing your path - with the strong beams from the spotlights turning what seems like thousands of metres of road ahead into daylight.

Both sets of lights are controlled by buttons on the right of the steering wheel, useful for when you only need one, or when standard high-beams alone will do.

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.
