2023 Isuzu MU-X vs 2017 Tesla Model S

What's the difference?

Isuzu has proven that you don't need a lot of horses in the stable to get things right and the MU-X 4x4 LS-T is a horse I can back. It offers kid-friendly growing space, a roomy interior for parents and a powerful engine. It also has just enough creature comforts to make it competitive against its rivals but I would have liked to have seen a few more scattered throughout for the price tag, especially in that third row. While the driving is pretty solid, the ride isn't as refined as it could be, but my family really enjoyed the MU-X this week and it earns a solid 8.0/10 from us.

I spoke to a friend who bought a Model S before one had even hit the ground here in Australia. He chuckled when I told him how much this car cost but then said something I'd already suspected. "My mates who own a P100D would never drop that kind of money on a normal car. Buying a Tesla is like buying shares in the company, you're buying into the future."

And that's kind of the point. A $300,000 Audi RS7 (fully-loaded, obviously) is a bit slower in a straight line, looks just as good, is extremely well-built and emits noises that make people like me go as weak at the knees (just as the Model S' acceleration does). And would probably win a 10 lap race with the Tesla around Mount Panorama.

The Tesla is the future of cars. It may still be decades before the internal combustion engine is gone, but Tesla buyers are getting the jump, and today the Model S is the best car in which to make that leap.

At 1825mm tall, the MU-X has clear SUV proportions, but urban drivers need not stress because, at 4850mm long and 1870mm wide, it's still accommodating in a tight car park.

The nose is nicely tapered and accentuated by a large chrome grille with black highlights and sharp LED lights. It's very similar to its stablemate, the D-Max, but the addition of the ‘boot' doesn't compromise it's kerb-side appeal. There are no sharp blocky-looking edges on this and while handsome, it doesn't prance to announce its presence. There's a subtlety to it's styling that should see it age well.

The interior has soft touch points throughout that are mixed with a nice combo of trims to make it feel refined but it is let down by flimsy/plasticky sun visors and door panelling.

The Model S is definitely the looker of the three Tesla models on sale (the Model 3 might be some way from release, but you can reserve one and it's... weird-looking). With a slinky, Jaguar XF/Audi A7 roofline and low-slung stance, it looks the business. Like the X, the detailing of the car's surfacing and panel gaps aren't where other $200,000+ cars are, but it has improved a lot over the last couple of years.

The cabin has improved even more than the exterior.

The styling is quite sparse, really. Teslas look like computer renders in real life, especially in white, with little in the way of jewellery or detailed design elements. And that's probably the idea. It's a cleaner design than when first launched, with a simpler, flatter snout that brings out the headlights better.

The cabin has improved even more than the exterior. It's still the same minimalist design, but it fits together much more tightly than it used to. The 17.0-inch portrait screen is still there in its central but skewed-to-the-driver position and is now up to version 8. It's an impressive interface, covering off the vast majority of functions in the car, and is mostly easy to use. The responsiveness is key to its usability. If it was underpowered, you'd quickly start demanding real buttons.

The interior is roomy with decent leg and headroom available to front and middle-row passengers. The side steps made it easy for my six-year old to get in and out without my help (always a plus) and the high ride ensured a good view for him this week.

Storage throughout is adequate for an SUV of this size but the middle console and drink bottle holders could be a little deeper and wider. The double glovebox and hidden retractable cupholders in the dashboard are a highlight, though.

There are enough creature comforts in the front and middle rows to satisfy individual family members, however, I was disappointed that there is only one USB-A port up front and no wireless charging pad. But the second row gets two USB-A ports, which should help with staying charged up on a road trip.

As far as third-row amenities go, it's a bit lean and tall adults will complain about the space, but it was fine for my 168cm height (5ft6). It's easy to climb back there because of the tumble-fold function of the middle row and the multiple grab handles.

I always like to have a powered tailgate and the level load space of the boot made it very easy to slide gear in and out this week. The boot is very practical with 311L of space available when all rows are in use but you can bump that up to a massive 1119L when the third row is flat. You can also knock it up again to a whopping 2138L with all back seats are folded down, if you need it.

Impressively, you also get a full-size spare tyre too.

The 9.0-inch touchscreen multimedia system is easy to use once you get used to it and the built-in satellite navigation was a plus. It has wireless Apple CarPlay and Android Auto and it was simple to get the connection going but it did take a few minutes for the CarPlay to kick in once you started the car up. I prefer to see a 360-degree view camera on large SUVs like this but the reversing camera in the MU-X is adequate and clear.

The Model S is a rare car in this class in that it has an almost completely flat floor, meaning rear seat passengers don't have to negotiate a transmission tunnel. The two motors run physically independently of each other so there's no crankshaft to get in the way.

The floor is thicker than a normal car, it's like a big skateboard underneath. That means your knees are up higher, which might cause numb bum on a long trip. The rear seats are comfortable enough, but middle seat occupants might feel like the outboard passengers are falling into them.

With all that torque, when you do load it up, the extra kilos barely make a dent on the performance.

The view out isn't too bad given the rising window line, and if you've got the big two piece sunroof (without cover, irritatingly... ), it's quite airy out back. And hot (with the sunroof), but you do get rear air-con vents.

The boot is an eminently sensible 744 litres with the seats up and 1795 with the seats down, although the floor doesn't fold flat. While it's a big boot, it's relatively shallow so your suitcases go in on their sides. Up in the front boot (or froot) there's another 150 litres, so you can pack a lot in to the Model S. And with all that torque, when you do load it up, the extra kilos barely make a dent on the performance.

Tesla is basically a technology company - well, a battery company - that makes cars, so the features and options reflect that. It's a gadget-laden five-door hatch powered exclusively by electricity and seemingly full of things that will drain the batteries quickly.

If you view the car's price purely through its standard features list and the cost of options, you're missing the point. If it had a 3.0-litre turbo six, there's no way you'd pay this kind of money for the Model S. But it doesn't have that, it has a bleeding edge battery pack and propulsion system.

The Model S can be had for as little as $118,652 for the 60 offering 400km range, rear-wheel drive, and 5.8s 0-100km/h (but move quickly, Tesla has just axed this model), or as much as this P100D which starts at $250,582.

Standard are a seven-speaker stereo, leather-like trim, 19-inch alloys, reversing camera, 17.0-inch touchscreen, keyless entry and start, forward collision warning, digital dashboard, electric front seats, sat nav, auto LED headlights, auto wipers, internet connectivity via included SIM card, power mirrors and windows and air suspension.

Our P100D came with 21-inch grey 'Turbine' wheels ($6800), panoramic roof ($2300) multi-coat pearl paint (white, $2300) and carbon-fibre interior trim bits for $1500, as well as a carbon lip spoiler for another $1500.

We also had the 11-speaker audio upgrade (with neodymium magnets, don't you know) for $3800 and the 'Subzero Weather Package' (seat heaters, heated steering wheel, wiper blade defrosters and washer nozzle heaters) and on-board high-power charger (speeds up charging with the 'Tesla Wall Connector', $2300).

There was also 'Enhanced Autopilot' ($7600) and 'Full Self-Driving Capability' ($4600). The former is meant for highway running, and comes with four cameras (up from one) and 12 ultrasonic sensors around the car, as well as upgraded processing power to run it all.

The full self-driving is meant for around town. The idea is you punch in a destination, or speak to the computer or passive-aggressively stay silent, which triggers the car to check your calendar and take you to the address in the appointment. Part of the extra cost of that is yet more cameras (up to eight), more sensors, and more number-crunching power.

A 'Premium Upgrades' package adds the overkill of a 'Bioweapon Defense (sic) Mode' that knocks out 99.97 per cent of exhaust particulates and other contaminants.

We would love to tell you how all that worked, but being Tesla 'Hardware 2', it's not ready yet. While these features are being fleet-tested by 1000 cars in the US, your car will run it all in "shadow mode" for data and behaviour validation. One day you'll go to your car and a software update will be ready to download and install the functionality.

Unusually, you can retrofit both of these features for about $1500 more (each) than if you order them up-front. That's very cool and Tesla is probably the only car company in the world that will let you do it.

The 17.0-inch screen's software is regularly updated, like a mobile phone's. Also like a mobile is the sometimes less successful update, in this case the slightly bewildering and difficult-to-use music interface that is very keen for you to make a selection with voice commands, but not ones that go through your phone.

A 'Premium Upgrades' package adds the overkill of a 'Bioweapon Defense (sic) Mode' that knocks out 99.97 per cent of exhaust particulates and other contaminants, using two activated carbon air filters for other nasties like NO2 and hydrocarbon exhaust fumes.

LED turning lights and fog lights, real leather on the armrests, steering wheel and lower dashboard (if you also have leather seating), nappa leather and Alcantara on the dashboard, soft LED interior lighting, power tailgate and backlit door handles for $5300. Thankfully, the silly self-opening front doors in the Model X's pack aren't in this little lot.

Grand total? $297,792. On the road in, say, NSW... $313,013. Youch.

All MU-X models share the same 3.0-litre, four-cylinder turbo-diesel engine but it perfectly complements the 4WD system. With a maximum output of 140kW of power and 450Nm of torque, most weekend adventures can be pursued. It also doesn't feel like you're digging deep for that power, which is great.

The six-speed auto transmission is surprisingly smooth but occasionally the pick-up isn't super quick when you're going from a standstill. It can feel heavy in that situation but I was still confident when I had to cut across city traffic, so it wasn't a major bother.

The P100D ships with two electric motors fed by a huge battery pack which triples as the bulk of the chassis and a super-strong crash structure. It's also shared with the Model X SUV.

Combined power output is 568kW with more of it out the back rather than up front. Torque is quoted at 1000Nm, but it's likely more than that. Claimed 0-100km/h time is a mildly unbelievable 2.7 seconds, with a further two-tenths to be shaved off when you press and hold Ludicrous Mode and accept a warning that you'll wear the car out faster if you use it.

With 'Ludicrous Mode' comes not just software but a higher capacity fuse that allows more power to be drawn from the batteries for longer to provide the searing acceleration.

The official combined fuel cycle is 8.3L/100km. Real-world testing saw my figure at 7.7L. I've been doing a good mix of open-road and urban driving this week, so I think that's very respectable for the size of this car.

The MU-X has an 80L fuel tank with an approximate driving range of 900km.

Zippo. Obviously with the new rules for Tesla Superchargers, it's not as cheap to own and run a Tesla as it was before (from January 2017, all new orders don't get free juice after the first 400kWh), but if you charge it at home (and can get away with it), it'll probably be cheaper than using Tesla's chargers. If you look, there's a company offering $1 per day charging for electric cars.

If I'd charged the car to 100 percent rather than the 80 percent recommended by Tesla for most charges (past that mark, the charge rate drops and the software has to slow to a trickle, doling out the electrons to the different cells), I would have managed just over 400km on the charge.

Overall, I've enjoyed driving this. The engine has enough grunt to make you feel you can handle most situations and despite being a turbo-diesel, it's not super loud in the cabin. You do notice a fair bit of wind noise, though.

The only real drawback to the driving experience has been the ride comfort. I'm a fan of the D-Max and feel it outruns its stablemate in this area. I'm not sure if it's the suspension or tyres but you feel a lot of the bumps in the road.

The high driving position and the visibility out of the windows has been fantastic and helps make up for the ride quality. The steering is firm and direct, making this feel like a smaller car than it is and that's a nice feeling to have in a large SUV.

It's not a beast to park either and you'll be comfortable navigating your local shopping centre car park.

The first time I drove a Model S, I enjoyed the acceleration and the silence of the electric motor (this was back in the Dark Ages when even the P90 only had one motor). And that has remained, with the air suspension providing a firm but comfortable ride despite the P100D's 21-inch rims and very low profile tyres. Electric motoring in any electric car is addictive.

Much progress has been made (yes, I'm getting to the acceleration, stay with me) in the way it drives. The earlier cars felt too computer gamey, with little feel through the wheel or the seat of your pants. The steering is better, especially in Sport mode, but not a lot gets through the air suspension, so it takes a while to build confidence in the chassis.

One passenger became quite emotional, almost crying. And not just because they were stuck in a car with me.

On the freeway (look, you can read ahead if you must) it's amazingly quiet, with just a bit of a rustling around the mirrors. Well, of course it's quiet, it's electric. For chassis and NVH (noise, vibration and harshness) squashers, not having the marvellous engine noise means much harder work to dull the other noises you just don't hear when there's an internal combustion engine.

And there's the acceleration. As the driver, you obviously know it's quick. Mash the throttle and the response is instant, the horizon closing in on you like you're attached by a very stretched and immensely strong bungee strap that's just been released. The way cars disappear in your rear vision mirror is hilarious.

It's more fun as a passenger, though. The Model X elicited whooping and laughing, but the P100D's extra 0.6s-worth of acceleration over the P90D, delivered with a truckload more G-force, equals silence. One woman said she was glad I'd caught her before dinner rather than after, before bursting forth with a range of expletives. One passenger became quite emotional, almost crying. And not just because they were stuck in a car with me.

The Model S comes with six airbags, ABS, stability and traction controls, three ISOFIX points, rollover sensors, emergency power disconnect. Additionally, when the software arrives, you'll have full AEB (ours was limited), self-driving and an ultra-clever active cruise that'll change lanes and overtake if the car you're following falls below your set speed.

The Model S scored five ANCAP stars, the maximum available, in April 2015 via the sharing arrangement with EuroNCAP.

This comes with a six-year/150,000km warranty, but it is usual to see an unlimited kilometre term in this class.

The MU-X comes with a seven-year capped-priced servicing plan and services are competitively priced at an average of $527. Servicing intervals are reasonable at every 12 months or every 15,000km, whichever occurs first.

Tesla offers a four-year/80,000km warranty with a parallel eight year/unlimited kilometre warranty for the battery and drive units. Roadside assist applies for the four year warranty period.

Tesla offers two maintenance plans, three and four years in length. The three year plan costs $2100 and the four year $3175. Paying for the services individually over the same period will cost $2300 and $3425 respectively. That includes a wheel alignment (if needed), but it isn't particularly cheap when compared with 'normal' luxury cars.

Your first 400kW/h of recharging is free using Tesla's supercharger network, so that would be four full charges from empty (which you wouldn't do, obviously), or about 1600km worth. After that, it's 35c per kWh or $35 for a full charge.
