Tesla Model X vs Porsche Panamera

What's the difference?

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 Panamera is the ‘have your Porsche and drive it too’ model.

It encompasses the fun of the 911 while still being a comfortable daily driver that can easily fit a family of four. The cabin is sumptuously styled and not hurting for features, either.

Could the ownership costs and storage be better? Probably, but if you’re looking at this model, those items will probably be lower priorities for you.

For my little family of three, the base model Panamera is a win.

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.

Some people might not understand the obsession or loyalty Porsche owners have towards their cars  but if you’re a fence sitter, get in the Panamera. It will make you understand because after driving one... you'll hear yourself say 'I get it'.

The base model has the goods with the engine outputs to ensure the driving experience remains fun and responsive.

The Panamera is no wild bronco, it's a cool customer. The composure for power delivery is unlike other performance sedans you may have driven. Acceleration is effortless without any twitchiness. You never feel out of control.

The air suspension means you hear the bumps more than you feel them but you still get excellent road feedback as a driver.

Passenger comfort is high, despite the cabin being quite loud with road and engine noise, because the seat and ride comfort remains well-cushioned. Fatigue and jostling are at a minimum.

The handling of the Panamera when it comes to cornering and steering feels dynamic and agile. I made a point of doing multiple mini roadies this week, simply for the joy of driving it.

While the Panamera is the most fun on a winding mountain road, it's a pleasant open-road cruiser as well.

The base Panamera has three driving modes - 'Normal', 'Sport' or 'Sport Plus' with a 20-second power booster available when you need extra oomph.

The Normal mode is sufficient for daily driving and the Sport Plus offers stiffer suspension and handling but the preference is to keep it in Sport mode.

Mainly because in this mode you get an awesome throatiness from the exhaust as well as the dynamics you expect from a sports car.

It’s a bit deceptive but the Panamera is massive and sits at 5052mm long and 2165mm wide - so, it definitely fills out a parking space!

However, the 360-degree view camera system is one of the best in the segment but you may still get choosy with where you park it.
