2021 BMW X5 vs 2019 Tesla Model X

What's the difference?

There is no doubt that BMW seriously stepped up its game with the fourth-generation X5, raising its levels of luxury and technology, all the way to that of the flagship 7 Series.

The X5’s mix of imposing looks and relatively well sorted dynamics is complemented by the xDrive30d’s brilliant engine and transmission.

It’s no surprise, then, that the X5 continues to be its best in xDrive30d form. There really is no need to consider any other variant.

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.

When it comes to ride and handling, it would be easy to argue that the X5 xDrive30d’s combination is class-leading.

While its suspension (double-wishbone front and multi-link rear axles with adaptive dampers) has a sports tune, it stills rides comfortably, wafting over uneven surfaces with ease and quickly regaining composure over bumps. It all feels suitably luxurious.

However, the optional bi-colour 22-inch alloy wheels ($3900) fitted to our test vehicle often catch sharper edges and spoil the ride over poorer surfaces, so you should probably stick to the standard 20-inch rims.

Handling-wise, the X5 xDrive30d does naturally lean into corners during spirited driving when in its Comfort drive mode.

That being said, overall body control is relatively strong for a large SUV, and the Sport drive mode does go some way towards tightening things up, but the fact is, it’s always going to be hard to defy physics.

Meanwhile, the X5 xDrive30d’s electric power steering is not only speed-sensitive, but its weight is adjustable via the aforementioned drive modes.

In Comfort, this set up is well-weighted, with just the right amount of heft, however, change it to Sport and it becomes heavier, which might not be to everyone’s taste. Either way, it’s relatively direct and offers solid levels of feedback.

That said, the X5 xDrive30d’s sheer size is reflected by its 12.6m turning circle, which makes low-speed manoeuvres in tight spaces more challenging. The optional rear-wheel steering ($2250) can help with that, although it wasn’t fitted to our test vehicle.

In terms of straight-line performance, the X5 xDrive30d has a thick wad of maximum torque available early in the rev range, which means its engine’s pulling power is effortless all the way through to the mid-range, even if it can be a little spiky initially.

While peak power is relatively strong, you rarely need to approach the top end to make use of it, because this engine is all about those Newton-metres of torque.

Acceleration is therefore spritely, with the X5 hunkering down and charging off the line with intent when full throttle is applied.

A lot of this is performance is thanks to the transmission’s intuitive calibration and general responsiveness to spontaneous inputs.

Gear changes are quick and smooth, although on occasion they can be a little jerky when decelerating from low speeds to a standstill.

The five drive modes – Eco Pro, Comfort, Sport, Adaptive and Individual – allow the driver to alter engine and transmission settings while on the move, with Sport adding a noticeable edge, but Comfort is what you'll be using 99 per cent of the time.

The transmission’s Sport mode can be summoned at any time, with a flick of the gear selector leading to higher shift points that are complementary to spirited driving.

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.
