Mercedes-Benz Vito VS Isuzu D-Max

The Vito offers exceptional comfort for the driver, with the prestige look and feel of its leather-wrapped and height/reach adjustable steering wheel combined with a driver’s seat offering a fold-down inboard armrest, height/reach-adjustable lumbar support plus adjustable base-cushion rake and length.

A left footrest would be icing on this comfort cake, but in its absence there’s plenty of clear floor space in which to rest your left foot.

Eyelines to all mirrors are good and although the centre-seat headrest for the Cargo Pack bench partly blocks the central mirror’s rear view, most of the tailgate’s window remains clear.

Given the huge blind-spot over the driver’s left shoulder created by the cargo bay’s solid walls, the Vito’s blind-spot monitoring, rear cross-traffic alert, 360-degree camera etc are effective in creating a safety zone in such a vulnerable area.

The steering feel is superb, as we’ve come to expect from Mercedes-Benz commercial vehicles. Cabin noise remains commendably low even at highway speeds, during which the engine needs only 1700rpm to maintain 110km/h. However, tyre noise can become intrusive on coarse bitumen surfaces.

Engine response in city and suburban use is excellent, as the nine-speed auto efficiently keeps the turbo-diesel operating within its 1350-2400rpm peak torque zone. And 440Nm of torque is competitive for a van this size, ensuring strong acceleration with or without a load.

The driver-selectable Sport and Manual drive modes provide greater driver engagement and direct control respectively, but for most driving the default Comfort setting provides a commendable balance of comfort and engine response which allows the Vito to shine in a working role.

We proved this after loading 770kg into the cargo bay, which with driver equalled a total payload of 870kg which was only about 60kg under its legal limit. The coil-spring rear suspension compressed 50mm under this weight, which still left more than enough suspension travel to ensure there was no bottoming-out during our test drive.

This included our usual 13 per cent gradient, 2.0km set climb at 60km/h, in which it downshifted to fourth gear and 2000rpm (bang in the middle of its peak torque band) to easily reach the summit.

Engine-braking on the way down, in a manually-selected second gear, was impressive for an engine with relatively small displacement restraining almost 900kg in payload, requiring only one firm application of the brake pedal. Overall, it proved to be a competent load-hauler.

The D-Max has never been a stand-out performer on-road in the ute segment, but it’s never been atrocious either.

The engine and auto combination yield a solid drivability rather than any liveliness, which works fine in this ute package.

Suffice to say, the D-Max is consistently middle of the pack when it comes to ride and handling or refinement comparisons, but again that suits this ute package. 

Besides, the D-Max is a body-on-frame ute with leaf spring rear suspension, so it can’t be expected to produce sportscar-like driving qualities, though the most recent upgrades to the D-Max did improve the steering and driver-assist tech.

But then came the Blade project, which wasn’t about improving the ute’s around-town driveability: Isuzu brought in the Walkinshaw Automotive Group, one of Australia’s leading automotive engineering firms, to make a version of the D-Max that was even better at off-roading than the standard unmodified D-Max.

Boiling down thousands of kilometres and man-hours of Walkinshaw’s work on the Blade into the most salient points for this yarn does not accurately reflect the effort of those involved in the years-long process … but here goes anyway: Walkinshaw has designed, engineered and remanufactured some of Australia’s most iconic nameplates, and, while the Blade reworking doesn’t introduce any new mechanical or driver-assist tech set-ups to the D-Max package, the introduction of new all-terrain tyres, wider wheel track and Aussie-tuned suspension (including Monroe 35mm MTV twin-tube dampers with lifted spring seats) has added a welcome measure of composure to this ute’s on-road behaviour.

And Isuzu big wigs must be feeling a bit chuffed at this point in time because Walkinshaw’s off-road mods have produced real results where they count most: off-road.

The standard D-Max in LS-U+ guise is an impressive 4WD ute, but the Blade version is a touch better on a variety of terrain for a number of reasons.

For starters, the Blade’s Walkinshaw-developed suspension set-up, with those 35mm twin-tube dampers in the mix, yields a more agreeable drive, with more comfort and better chassis control than a regular D-Max on fast dirt tracks and corrugated gravel roads. It manages to subdue most of the lumps and bumps you’re bound to drive over on your way to a beach- or bush-camping destination.

The Blade’s wheel track – at 1602mm, 32mm wider than the LS-U+’s 1570mm – gives this ute a slightly more planted posture than its standard stablemate for improved stability and handling.

And while the Blade’s tyres aren’t gung-ho mud-terrains or something similar, its 275/65R17 Goodyear Wrangler Duratrac RT all-terrain tyres do work sufficiently well on-road and off.

For low-range 4WDing, the Blade has all of the D-Max good stuff – including a tractable engine with plenty of low-down torque and a recalibrated off-road traction control (part of the most recent D-Max upgrades) – but its ground clearance (244mm vs the LS-U+’s 240mm) and off-road angles (29.2° approach, 19.2° departure and 25.2° breakover vs the LS-U+’s 30.5°, 19.0°, and 23.8°) don’t represent as much of an improvement over its stablemate as you’d expect in a vehicle touted by Isuzu as “an off-road ute without compromise” and “an unparalleled combination of off-road performance and rugged reliability”.

The Blade feels vulnerable to underbody knocks from rocks and the like, but it has 3mm-thick steel bash plate protection so there’s no need to lose any sleep over a few ‘rubbing dirt’ moments.

Its tubular sidesteps at least seem hardier than the standard D-Max’s sidesteps and seem able to cop knocks from rocks without crumpling.

If there’s any need for a vehicle recovery, the Blade has eight-tonne load-rated recovery points (with bracing between chassis rails for torsional rigidity) to work with.

Also, if you’re thinking about using your Blade as a touring platform, at a listed kerb weight of 2204kg, it is 89kg heavier than the LS-U+, and its payload is 896kg (down form the LS-U+’s 990kg). GVM is 3100kg, GCM is 6000kg.

Towing capacities remain at 750kg (unbraked) and 3500kg (braked).
