Mercedes-Benz Vito vs Tesla Model X

What's the difference?

The Vito 119 Panel Van LWB offers excellent performance and driver comfort, with styling and all-round refinement that could make it an appealing business partner. However, the absence of an ANCAP star rating and a sub-one-tonne payload limit could be deal-breakers for some tradies and fleets alike, along with a list price that exceeds its Toyota HiAce LWB equivalent by almost $30K. Therefore, only a potential buyer can decide if its positives outweigh its negatives.

After nearly 700km of testing with both cars, it’s fair to say that the Tesla is indeed a capable tow vehicle, provided you keep the distances relatively short and plan around charge station locations.

Overall average - Penrith to Bathurst to Penrith

Fuel and energy consumption will always depend on the driving conditions, which is why we chose different routes for each leg of our testing.

Averaged across the two legs, towing the caravan with the Model X used 101 per cent more energy than without, or halved its driving range, which sounds a bit scary.

The LandCruiser by comparison added 63 per cent on average, which is still a big difference, but matters less in the real world when its big fuel tanks would still give you about 760km of driving range, which can be refilled quickly at any diesel-stocked servo.

So you could do a weekend trip with the caravan from Penrith with one supercharge in Bathurst, but it would’ve been highly unlikely to manage the extra 55km if you were leaving from Sydney CBD.

The bottom line is that there’s plenty of things - like smaller camper trailers - lighter than our caravan that will help the Tesla to do the towing job better right now.

Compared to the ‘Cruiser, the Tesla is a lesson in the benefits of a lower centre of gravity and road-focused handling.

As always, bigger batteries and more recharge points will go a long way to rectifying the Tesla’s towing shortcomings, and I'm sure we'll get there eventually.

But no matter what, its acceleration performance under load is simply excellent.

Thanks to our friends at Avida for making this test possible with the use of the 17-foot Avida Wave Tourer Electric Pop-Top single-axle caravan. They can also be reached on 1300 428 432.

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.

Energy consumption is just one element of a tow vehicle though, with stability, braking and acceleration performance being the most important details.

The big ‘Cruiser is always a safe bet for towing heavy loads, but it's fair to say its off-road ability, tall body and short wheelbase mean it could be better on the road, and the Tesla goes some way to proving that.

With all those batteries mounted nice and low, the Tesla is significantly more stable with 1.7 tonnes on the back than the LandCruiser, in all conditions. It’s also helped by that longer wheelbase.

The Tesla’s airbag suspension is another surprise advantage, and while it can be a bit choppy around town over minor bumps, bigger bumps on the highway are soaked up really nicely and it all settles quicker than with the LandCruiser - even with the caravan on the back.

Tesla is famous for instant acceleration at any speed, and this effect remains when towing. The LandCruiser’s twin-turbo V8 (with max torque available from 1600-2600rpm) has long been a benchmark for tow vehicles, but the Model X makes it feel sluggish by comparison.

You know how caravan vehicles are usually the slow ones up hills? This time, we were the ones doing the overtaking, even up the steep bends heading out of Lithgow. To overtake, it just takes the slightest flex of your right foot.

Clearly there’s a big caveat though when it comes to how much energy it’s consuming while you’re enjoying that performance, and it’s deceptive because it doesn’t make any more noise like a conventional engine when you’re pushing it. 

You’d also think the weight of the van would overcome the engine-braking effect of the regenerative brakes, but they are still very effective at conserving your brakes downhill and preventing the car from running away from you, and no doubt giving the batteries a bigger boost at the same time.

On that note, the LandCruiser’s cruise control also does a great job of witholding speed on downhill runs, proactively dropping gears to engine brake enough to keep the Avida Wave in check.
