What's the difference?
The Holden Colorado is a quiet achiever in the ute market: it has a solid rep as a work-and-play vehicle, generally records positive results in objective editorial reviews and comparisons, and it sells well.
But how does a Z71 do as a tow vehicle? Read on.
The VW Transporter has been in production for more than 70 years, as its bloodline can be traced back to the original rear-engine split-window ‘Kombi’ launched in 1950. So, during those seven decades, the German manufacturer has no doubt learned a thing or ten about building light commercial vans.
The current T-series of Transporters was launched in 1990, which was the first of six generations culminating in the current T6 range, that comprises not only work-focused vans but also people-mover, campervan and cab-chassis variants.
VW recently released a 6.1 version of vans and people-movers. That decimal point brings significant upgrades of standard safety equipment, headlined by City Emergency Brake (CEB), plus new variants. We recently put a Transporter 6.1 to work for a week and discovered a very capable mid-sized (2.5 to 3.5-tonne GVM) van with few flaws.
The Holden Colorado Z71 is a pretty decent towing machine, handling all aspects of general load-lugging duties with a quiet reliable efficiency. In simple terms, it kept the whole ute-and-van combination trucking along nicely.
The Z71 is a solid Colorado package all-round with some welcome flashiness to its functionality.
The Transporter boasts a level of mechanical refinement, engine performance, ride quality, heavy load-carrying ability and general driver comfort that sets a high benchmark in this category. If not for its lack of an ANCAP rating and unacceptably high internal noise levels at highway speeds, it would be hard to fault.
The Colorado is a good-looking unit, so it follows that the Z71, the Colorado line-up's top dog, should be the best-looking vehicle in the entire range. And it is. Look at the photos yourself and make up your own mind.
The Z71's black highlights everywhere, the roof rails, side steps and fold-away tonneau cover add functionality to the flashiness.
Under its slick exterior, the Z71 sits on a steel ladder-frame chassis.
There may be no mechanical differences between the Z71 and other similarly-powered Colorado utes, but this is not merely a sticker-pack special – this is something more substantial than that. Don't believe me? Keep reading.
Our test vehicle’s 3400mm wheelbase is 400mm longer than the standard model, resulting in a corresponding increase in overall vehicle length to 5304mm and a 300mm increase in turning circle to 13.2 metres.
Its 1904mm width is an easy fit in most loading zones and the standard roof’s 1990mm height means it can access most underground and multi-storey carparks which typically cap vehicle heights under 2.2 metres. It comes standard with a kerbside cargo bay sliding door and single-lift tailgate.
The well-developed front wheel-drive chassis is simple and robust with MacPherson strut front suspension and semi-trailing arm coil-spring rear suspension, the latter equipped with stout rubber cones inside the spring coils to provide a second stage of support under heavy loads. Optional heavy-duty and rough road suspension packages are also available. Brakes are four-wheel discs.
You can always pick a van designed for hard work by the amount of black plastic in body areas prone to high wear and/or scrapes, chips and dents and the Transporter has most of those covered, including the front and rear bumpers, lower rear pillars, hubcaps, door handles and mirrors.
The cabin has a back-to-basics look and feel as highlighted by numerous plastic caps blanking dashboard slots where switches are fitted to higher-equipped models. However, it has most of what you need and none of what you don’t for this working role. Even so, the lack of fold-down inboard armrests and a driver’s left footrest are notable omissions and both would be welcome for long stints behind the wheel.
The Z71 has a Colorado carry-over interior, which is nice and simple, with some Z71 branding stitched in the front seats.
For starters, there are grab handles for the driver and front passenger – I'm a big fan of grab handles.
The dash is a basic layout – but made family-friendly with expanses of tough plastic and soft-touch leather – and it has everything you need. The centre console houses an 8.0-inch colour touchscreen with Apple CarPlay and Android Auto and standard nav.
There is a USB port in the centre-bin, and there's a 12V socket in the back of that bin for back-seat passengers.
The cabin is reasonably comfortable; the front seats – in fact all of the Z71's seats – err on the side of firm rather than being well-cushioned. But, even in the back seat, when I sat behind my driving position, I had ample head- and leg-room.
There are the usual collection of storage spaces around the cabin – sunglasses, glove box, door pockets, seat-back pockets – but a long centre-bin lid impedes access to the cupholders in between driver and front-seat passenger, and there are no cupholders in the back seat's fold-down centre arm-rest.
There are shallow storage spots under the rear seats, one of which contains your jack etc.
Overall fit and finish is impressive without being spectacular, but that's fine with me.
The tray is 1484mm long, 1534mm wide (1122mm between the wheel-arches) and 466mm high. Back there, you get Premium DuraGuard Spray–on tub liner, which seems sturdy and durable, as well as four solid tie-down points.
With its 1865kg tare weight and 3000kg GVM, our test vehicle has a genuine one-tonne-plus payload rating of 1135kg and up to150kg of that can be carried on the roof. It’s also rated to tow up to 2500kg of braked trailer but that would require a sizeable 583kg reduction in payload to avoid exceeding the 4917kg GCM or Gross Combination Mass, which is how much it can legally carry and tow at the same time. Or you could keep the full payload and reduce the towing limit instead, from 2500kg to 1917kg, which may be a more useful compromise depending on work requirements.
The cargo bay, which offers 5.0 cubic metres of load volume, is 2975mm long, 1700mm wide and 1410mm high with 1244mm between the rear wheel housings. That means it can carry two 1165mm-square standard Aussie pallets, or up to three 1200 x 800mm Euro pallets, secured by a choice of eight load-anchorage points. However, the single-lift tailgate could make rear forklift access tricky, depending on forklift design and reach. The sliding door has a generous 1017mm opening for kerbside loading.
Although the load floor is bare and there’s no standard cargo protection for driver and passenger (optional rubber load floor mats and cargo barriers are available), the cargo bay walls and doors are lined to mid-height and the roof is also lined, with two roof lights providing ample illumination.
Cabin storage includes a large-bottle holder and huge storage bin in each front door, with a narrower second-tier storage shelf above which is ideal for holding smaller items like wallets, keys etc.
The dash provides another small-items cubby to the right of the steering wheel and the top dash-pad has small-bottle/cup holders at each end plus a steeply-angled open tray on the driver’s side which is ideal for storing clipboards, paperwork etc.
There’s no overhead sun-glasses holder but the passenger side of the dash offers two tiers of open storage and a large glovebox, plus another small-bottle/cup holder to the left of the gearshift console. An overhead storage shelf would be handy, given that there’s no centre console.
The Z71 auto 4x4 dual-cab has a list price of $57,490 MSRP. Our test vehicle is $59,260 MSRP because, over and above its comprehensive list of Z71 features (and those from cheaper variants), it has an electric brake controller ($740), and a towing package ($1030).
The Z71-specific features include a heap of style-based stuff, such as black fender flares, new front fascia, roof rails, and stickers on the bonnet, as well as 18-inch grey alloys (on Bridgestone Dueler H/Ts), sailplane sports bar, black highlights everywhere – including exterior door handles, mirrors and tailgate handle.
But the Z71 buyer gets plenty of useable real-world stuff such as roof rails, soft-drop tailgate, fold-away tonneau cover, and decent underbody protection.
There's also a leather-wrapped steering wheel and leather seats.
It has a 2.8-litre four-cylinder turbo-diesel Duramax engine, six-speed automatic transmission, a part-time 4WD system and a rear limited slip differential.
Bonus: there are plenty of genuine Holden-designed, -engineered and -tested accessories, including frontal protection bars, LED light bars, extended sports bars and more, that are probably available for your Colorado.
Our test vehicle is the long wheelbase variant with standard roof height, TDI340 turbo-diesel engine and seven-speed dual-clutch automatic transmission for RRP $47,990. This compares to higher-selling mid-sized turbo-diesel rivals like the Ford Transit Custom LWB 340L with six-speed auto ($47,590), Hyundai iLoad with six-speed auto ($42,710) and segment-leading Toyota HiAce LWB with six-speed auto ($45,240).
It's basic and work-focused as you’d expect, from its 16-inch steel wheels and 205/65R 16C tyres with full-size spare to its cloth seats and tough rubber floor covering in the cabin. However, that doesn’t mean you miss out on some useful and welcome creature comforts, like a leather-covered steering wheel with height/reach adjustment and infotainment controls, driver’s seat adjustable lumbar support, halogen daytime running lights (DRL), rain-sensing wipers, heated tailgate window with washer/wiper, multi-function driver’s display, four-speaker infotainment system with 6.5-inch touchscreen and multiple connectivity including Apple CarPlay/Android Auto plus lots of standard safety tech.
There’s also heaps of factory options available to help tailor a Transporter to suit an owner’s specific requirements including different cargo bay door and window configurations (including twin rear barn-doors), front passenger bench seat with under-seat storage, higher-spec infotainment systems and lots more.
The Z71 has a 2.8-litre four-cylinder turbo-diesel Duramax engine (147kW at 3600rpm and 500Nm at 2000rpm), six-speed automatic transmission, a part-time 4WD system and a rear limited slip differential.
This engine and transmission combination is the jewel in the Transporter crown with its energetic, flexible and efficient performance. The 2.0 litre, four-cylinder, direct-injection TDI340 turbo-diesel meets Euro 6 emissions using AdBlue and produces 110kW between 3250-3750rpm and 340Nm of torque across a 1500rpm-wide torque band between 1500-3000rpm.
The closely-spaced ratios in the seven-speed dual-clutch automatic are tailored to get the most out of this willing engine, with crisp and virtually seamless shifting. It also offers the choice of manual sequential-shifting, when hauling heavy loads in hilly terrain or simply for those wanting a more ‘sporting’ driving experience, but the seven-speeder usually does its best work when left to its own devices.
Our dash display read 7.9L/100km, but we recorded actual fuel consumption on test of 9.7L/100km. It has a 76-litre fuel tank, so expect an approximate driving range of 753km (according to our on-test fuel consumption), factoring in a 30km safety buffer.
On our towing loop, of more than 200km total, the dash was showing 14.5L/100km, but we recorded an actual fuel-consumption figure of 15.5L/100km. Expect an approximate driving range of 460km (according to our on-test fuel consumption), factoring in a 30km safety buffer.
We covered 283km (with auto start/stop disabled) which included about one third of that distance with a maximum payload. The dash display was claiming an average combined consumption of 8.1L/100km when we stopped to top-up the 80-litre tank. Our own figure calculated from fuel bowser and tripmeter readings came in even lower at 7.7 and both undercut VW’s official combined figure of 8.3L/100km. Needless to say, that’s outstanding real-world economy, which based on our figures should deliver a huge driving range of 900-1000km from its sizeable 80-litre tank. Possibly even further with auto start/stop enabled.
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.
Four-coil suspension provides a noticeably supple unladen ride quality, which is impressive for a commercial vehicle with a one-tonne payload rating. It also feels sure-footed and well planted on the road, particular on the many wet roads we encountered during a rain-affected week of testing.
With its upright steering wheel angle and nicely-weighted steering feel, it offers a comfortable almost car-like driving experience. The driver’s seat has height, backrest rake and lumbar adjustment; there’s no rake adjustment for the base cushion but it doesn’t really need it. There are also clear eyelines to all mirrors, a nicely-positioned gearshift and an uncluttered dashboard/instrument layout that’s easy to read and operate.
The 2.0 litre turbo-diesel has energetic response in its peak torque band between 1500-3000rpm, where most city and suburban driving occurs. Snappy, seamless up-shifting occurs between 1500-2000rpm, providing brisk acceleration with excellent fuel economy. At highway speeds, good gearing ensures the engine needs only 1800rpm to maintain 100km/h and 1900rpm at 110km/h.
We only have two criticisms. One is the size and limited wide-angle effect of the left-side mirror, given the huge blind-spot that a solid-walled long wheelbase van like this creates over the driver’s left shoulder. Although the Transporter is (thankfully) equipped with blind-spot monitoring, a larger kerbside mirror with a more convex shape to increase its angle of view would be welcome.
The other is high internal noise levels at highway speeds emanating from the rear wheel housings. On some grades of coarse bitumen it can sound like the roar of a jet engine, which is too loud for sustained periods and could be a deal-breaker if you do a lot of highway work. We have recently tested rival vans without cabin bulkheads which have appreciably lower cargo bay noise levels at similar speeds (most notably a Chinese brand), so it can be done.
The Colorado line-up has a five-star ANCAP rating as a result of testing in 2016.
Safety gear includes seven airbags, front and rear parking sensors, a reversing camera, Forward Collision Alert), Lane Departure Warning, a tyre-pressure-monitoring system, Hill Descent Control, Hill Start Assist, Trailer Sway Control and Roll Over Mitigation.
There's no ANCAP rating but the Transporter 6.1 adds to an already extensive list of active and passive safety with the following features now standard: front assist with city emergency braking (aka low-speed AEB), crosswind assist, side-assist including blind-spot monitoring/rear cross-traffic alert and multi-collision brake. There’s also driver and passenger front and side curtain airbags plus lots more.
Holden offers a five-year, unlimited-kilometre warranty across the Colorado range, with servicing required every 12 months or 12,000km. Capped price servicing applies over seven years/ 84,000km with the average annual cost over three years working out to be $405.
Five years/unlimited km warranty with 12 months complimentary roadside assist. Scheduled servicing every 12 months/15,000km whichever occurs first. Capped-price servicing for first five scheduled services up to five years/75,000km of $3082.
