BYD Seal vs Tesla Model X

What's the difference?

Those big auto executives have good reason to be worried, because the Seal is yet another impressive offering from China’s most formidable EV player.

It’s not perfect. In some ways it’s trying too hard to be a luxury car, and I think the software in particular could use a little work, but the Seal just does so much right I think it will be hard to be disappointed with one, particularly given its keen entry price.

In fact, if we had to pick one from the range, it would probably be this mid-spec Premium. The range and power on offer are stellar, and all for less money than an entry-level Model 3 or Polestar 2.

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.

I wasn’t expecting the Seal to impress me particularly. After all, it’s in this segment against tough competition, amongst recently updated versions of the Model 3 and Polestar 2, and while the previous BYDs I’ve driven have been a cut above their Chinese contemporaries, they also haven’t done a lot to stand out from the crowd.

Clearly, though, BYD has something to prove with its sporting sedan and the Seal is immediately impressive. The cabin is quiet and refined, the seating position is great it's smooth from take-off.

The steering has an artificial tinge to it removing a bit of feedback from the road, but proves at least quick and accurate at speed, and the handling is superb.

I kept pushing the Seal in my test drive, expecting gnarly characteristics to surface but they didn’t. This sedan grabs onto the road with excellent control and traction at the rear, spurred along by its long wheelbase, and improved tyre choice (Continental rather than the sub-par Chinese rubber worn by the Atto 3 and Dolphin).

While on paper it appears to have at least comparable motor output figures to the Polestar 2 and Model 3 - the Seal Premium doesn’t quite feel as rapid, its electric motor having a more relaxed vibe and responsiveness when you stomp on the go pedal.

This can be tweaked a little by dialling it up to Sport mode, and while it still doesn’t feel quite as breakneck fast as the Model 3, in particular, it’s plenty to be going on with.

The most impressive part of the Seal drive experience, though, is its ride. Ride is a constant problem for EVs as manufacturers go to lengths to tame the additional weight of batteries, but the Seal is the most impressive in its cohort, and by quite a margin.

It’s firm enough to be controlled, but has a lovely soft edge to it, so larger bumps, frequent corrugations, or sharper road imperfections don’t ruin your day.

The Model 3 and Polestar 2, even in their improved forms, are not this good. In a lot of ways the Seal’s suspension tune reminds me of the Mustang Mach-e. It has a soft edge, offset by a bit of secondary jiggle as the car settles, which is its only real blemish.

The Seal has no right being this good. It’s now not just matching its far more established rivals but doing some things significantly better.

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.
