What's the difference?
The idea of a Tesla that can tow sounds about as likely as an astrophysicist with three Olympic gold medals, who also moonlights as a hand model.
The EV brand has blazed a trail for every other mainstream and premium car manufacturer to jump on the electric bandwagon, and today they’ve still got the biggest batteries and most impressive range ratings, while also having the most extensive extensive network of charge stations made up of Superchargers and destination chargers, covering every state and territory.
They’re not perfect though, often displaying niggling build quality issues and production delays for upcoming models. There’s also a degree of uncertainty bred by a founder who flits between the modern-day space race, manufacturing flame throwers and offering to send miniature submarines to rescue stranded children.
But there’s no questioning the overall impact Tesla has had on the automotive industry, along with the incredible brand awareness and aspiration it’s generated from non-enthusiast Joe Average consumers around the world.
The Model X is also rated to tow, with a decent 2250kg braked rating and an integrated tow bar that folds out of sight when not in use, which both fits its SUV character and encourages you to give it a go.
The BMW X5 is a leading contender in the ‘Over $70K Large SUV’ division of Australia’s new car market, which is a hotly-contested segment boasting 15 marques and 25 models.
The X5 has hit an enduring sweet spot with Aussie buyers in terms of size, performance and price. BMW prefers to call it a Sports Activity Vehicle (SAV) as distinct from its Sports Utility Vehicle (SUV) rivals.
Clearly, any word association with a utility is something BMW Group Australia wants to avoid after recently launching its latest X5 range, which brings numerous enhancements including design revisions, increased standard equipment, refreshed powertrains and more.
We were entrusted with the digital ‘Comfort Access’ key to one of the latest X5s, to understand from a family car perspective why this model range enjoys such enduring popularity with prestige SUV (sorry, SAV) buyers.
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.
This is a luxurious prestige five-seater brimming with BMW’s latest design and technology that’s not only practical for weekly family duties but can also embrace spirited driving with the push of a button. A great all-rounder for families that like a sporty edge.
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.
It’s supremely comfortable, with front bucket seats that offer powered-adjustment of height, reach and backrest angle along with side bolsters that can tighten their grip of your upper torso.
There’s also two-way lumbar support, that adjusts not only how far it pushes your spine forward but also allows that pressure point to be raised or lowered.
Combined with its power-adjustable leather-rimmed steering wheel, it would be hard not to find a comfortable driving position.
Eyelines to all mirrors are good and over-shoulder blind-spots are minimal. Front and rear occupants can talk without raised voices thanks to low engine, wind and tyre noise at highway speeds.
As you’d expect, it has high build quality and a tangibly solid feel as though it was machined from a single block of steel, from the satisfying thuds of its closing doors to the absence of shudders or rattles on a variety of roads.
It also has two personalities, which can be switched in an instant. In 'Comfort' mode it will happily cruise around city and suburbs as a mild-mannered family car, fulfilling daily duties like work commutes, school drop-offs and pick-ups, supermarket shopping and the like.
However, flick the drive mode to 'Sport Plus' and you awaken, well, if not ‘the ultimate driving machine’ then something close.
Its optimised drivetrain and handling settings feel more like a sports sedan than a family car, which can turn any winding mountain road into an engaging experience.
It has impressive reserves of cornering grip and braking force, combined with sparkling engine response and fast sequential manual-shifting at your fingertips.
It feels impressively agile, with all-round response that belies its 2.0-tonne-plus kerb weight, backed by a symphony of sounds from its sublime in-line six.
