MG Im6 vs Subaru Solterra

What's the difference?

A super solid first outing from the IM brand. Don't let the pricing fool you, there is still bang for buck on offer in the IM6 Performance, even if it at times feels a bit too digital for my tastes.

The updated Subaru Solterra is now good enough to compete with rivals such as the Tesla Model Y and Zeekr 7X. The price is right as are the driving range and motor outputs.

There's room for improvement in terms of cabin packaging. The car doesn’t cater for taller, larger people up front, with the steering wheel placement and wide centre console. Cabin storage could also be much better.

Still, the Solterra is superb to drive. One of the best EVs I’ve piloted at this price.

I feel almost mean saying this, because there will be plenty of people who like the way the IM6 looks, and I don’t want to rain on their parade. But… I’m not one of them.

It reminds me a bit of the pre-facelift Tesla Model Y, in that it’s largely feature-less and a bit blobby, and there’s not a sharp angle anywhere to be found on the thing. Premium to me means powerful and assured — picture just about any Audi — whereas I just find this a bit bland and soft.

Anyway, I do like the big alloys, the insulated glass roof and the light treatment front and rear.

And I like the cabin. The seats aren’t leather, but they’re super thick and comfortable, and there is a genuinely premium air in the cabin, helped by the acreage of screens and the quality elements, like the little door panels.

The doors unlatch electrically, matching the pop-out door handles outside, but they can be a bit fidgety. Someone from MG told me how they worked (you kind of cover the handle and let the door come to you) but I watched everyone else who tried to open them struggle. If you're at the point where you have to explain how a door handle works, you might have over-egged the pudding.

The second screen below the main one acts a bit like a mobile phone. You can alter your home screen widgets and access the main menu, even as Apple CarPlay is synched at the top. You’ll get used to it, I’m sure, but I found it to be a bit fidgety.

Actually it reminds me a little bit of the Lexus trackpad, or whatever that hateful system was called, where you controlled the main screen via a little mousepad thing, though happily it’s nowhere near as annoying as that was.

The Solterra is a mid-sized SUV with sporty coupe-like styling and this update has seen the front of the car receive a new look which to my eyes is better than the previous face. 

The rest of the car’s exterior remains mainly unchanged in the design.

If you aren’t a fan of the Solterra’s look then check out Toyota’s bZ4X, which is its twin and has slightly more conservative styling, and while I do like the Subaru’s face, I think Toyota’s tail-light treatment is cleaner.

The cabin is modern with a large central media screen, a high-placed instrument display and a wide centre console with dual phone chargers. But the squareish steering wheel steals the show, completing the futuristic vibe.

This update has seen the centre console re-designed with the dual chargers added and the gear-shifter moved backwards away from the media display.

The cabin doesn’t have much in the way of glitzy touches, with dark materials dominating throughout. Hard plastics abound, but the interior still looks and feels premium.

The IM6 measures 4904mm long, 1988mm wide and 1669mm tall, and it rides on a 2950mm wheelbase, with IM describing it as a "mid-large SUV", though I expect it will be classed as a medium SUV Australia.

That said, ICE and EV mid-size electric SUVs are not cut from the same cloth, with the latter making use of a flat floor to maximise space. And so it is with the IM6, where backseat room is pretty damn impressive. I’m 175cm, and I had no problem at all with legroom or headroom, plus the same plush seats from up there are in the back, too.

There are also air vents but no temperature controls, and while there are USB ports, there is no regular household-style plug in the cabin. 

The glass in the windows is laminated, while the roof is double glazed, which MG tells me is Australian summer-proof, but I guess we'll know for sure in a couple of months.

There’s no shortage of cargo room either. There’s a 32-litre frunk up front, and there’s 646 litres in the boot with the rear seats in place. They’re 60/40 split, and if you drop them, luggage space grows to 1621 litres.

The towing capacity is a braked 1500kg, too, but I don’t expect to see many of these towing a camper trailer around.

The steering wheel’s square design is like that for a reason - it’s designed to provide the driver with a clearer view of the instrument cluster. But as noted in the past with other vehicles that choose this set up, the ergonomics don’t work for everybody - especially if you’re tall like me (I’m 189cm).

In my case the top of the steering wheel obstructs my visibility of the display, which shows vehicle speed among other crucial info. 

There’s also a problem with the clearance of the steering wheel and my legs. This is caused by a combination of my height, the low steering wheel and the limitations of how much it can be raised, the low-hip point in the seating position and the shape of the wheel. 

Add an overly wide centre console and space for larger and taller drives becomes even more cramped.

Moving the shifter back in this update also makes it more difficult to use for me and the mechanism is quite clunky.

Second row space is a much better story, with a flat floor, good headroom and lots of legroom even for me behind my driving position. The rear door aperture isn’t great and this has made installing child car seats and the corresponding child difficult.

Cabin storage could also be better. There’s no glove box, but there is space under the centre console, although this is now where the large driver’s manual lives. There’s a large centre console bin, big door pockets and four cupholders (two up front and two in the second row).

The second row has directional air vents and USB ports. There are USB ports up front, too.

Boot capacity isn't enormous at 421 litres in the entry-grade and 410 litres in the Touring. There’s no front boot, either. Under the bonnet is the Solterra’s front motor and electrical hardware.    

The Solterra is a five seater SUV, so no third row here.

The updated Solterra is offered in two grades. An entry-grade model, simply called Solterra, lists for $63,990 and above that is the Solterra Touring for $69,990. That’s up to seven thousand dollars more affordable than pre-update.

We tested the top-of-the-range Touring, which comes loaded with standard features, the only option being leather seats.

If you were wondering if you needed to spend the extra money on the Touring you might be pleased to know both grades have exactly the same powertrain and the entry-grade comes with plenty of standard features.

Coming standard on the entry grade Solterra are 18-inch alloy wheels, LED headlights and LED tail-lights, power mirrors, puddle lamps, a powered tailgate with kick-sensor (new with the update) and roof rails. 

There’s also synthetic leather seat trim, heated and eight-way power-adjustable front seats, a heated leather steering wheel, heated second row seats, dual-zone climate control, a 14-inch multimedia touchscreen (new) and 7.0-inch driver display, wireless Android Auto and Apple CarPlay, dual wireless phone chargers (new) and a six-speaker sound system.

The Solterra Touring comes standard with all this but adds 20-inch alloy wheels, a panoramic sun roof, ventilated front seats (new) and a 10-speaker Harman Kardon sound system.

The Touring also features a 220V vehicle-to-load (V2L) power outlet.

This is the real party trick of the IM6, because there’s a nuclear power plant under the metal somewhere. All up, the twin-motor setup produces a total 578kW and 802Nm, though I suspect you’re never accessing all the grunt all at once. Still, 100km/h zips by in 3.4 seconds, and the top speed is 239km/h. For the record, that’s exactly as fast the Ferrari Roma Spider I recently handed back, so yeah, it’s properly supercar quick.

The Solterra has two electric motors and as before there is one driving the front wheels, and one driving the rear wheels for all-wheel drive. Toyota’s bZ4X twin can be had in two-wheel drive and AWD.

The big news is the motors are now more powerful. Much more powerful. Combined output is 252KW (up from 160kW). That’s a huge increase but power is still less than the output of a Model Y or Zeekr 7X.

The front motor now makes 167kW/268Nm, while the rear motor produces 88kW/169Nm. Acceleration from 0-100km/h is about five seconds and that’s almost two seconds faster than the old version. 

Also on board is a 100kWh Nickel-Cobalt-Magnesium battery that produces a WLTP driving range of 505kms. Pretty good.

Charging is strong, too. The high-tech platform allows for 396kW DC fast charging, which is faster than what is currently offered in Australia. The claim is 30-80 per cent charged in 15 minutes. There’s also an external vehicle-to-load (V2L) port.

The updated Soltera’s battery size has increased to 74.7kWh. That’s up from 71.4kWh and means driving range has increased. 

The new, larger lithium ion battery delivers a range of 566km (WLTP) in the entry-grade Solterra (up from 414km). That addresses a big concern about the old car. The Touring has a range of 517km and any range above 500km is acceptable in my book.

Also big news is the increase in maximum AC charging capacity from 11kW to 22kW. DC charging capacity is the same at 150kW with 0-80 per cent charge in about 30 minutes.

Consumption officially ranges from about 14.6kWh/100km in the entry-grade Solterra to 16.0kW/100km in the Touring. The Touring we tested was reporting 17.0kW/100km according to the trip computer after 163km of testing in mainly urban conditions. 

First things first, don't get too distracted by the word "performance" here. The IM6 doesn't act like a performance car, it feels bit too plush, and bit too digital, for that.

But that's not necessarily a bad thing. Performance cars are often loud, raucous and uncomfortable, and the IM6 is none of those things. Instead, those mountains of power and torque make silky, silent progress absolutely effortless, which feels pretty premium to me.

MG makes a big deal of how much work went into insulating the cabin from noise – with active noise cancellation joined by double-paned insulated glass – and it is a properly calming and quiet space.

Also strong is the suspension, with the adaptive air setup soaking up most bumps and bruises, but I found it can clang over really solid bumps, sounding like it's bouncing off a stopper. The steering is solid, too, with a nice weight, if not overly talkative in the feedback department, while the rear-wheel steering helps eat into the turning circle for tight three-point turns.

The downside, though, is that it all feels a little too digital, and like there's been a little too much overthinking gone into it. Having to push a button to see behind you in a hurry is bonkers (see my explanation in the Safety section below), and the secondary screen is more annoying than intuitive. And there were several bings or bongs I couldn't even identify. All of which interrupts the otherwise calming nature of the drive experience.

The Solterra may slightly lag behind rivals in some areas such as range and power output, but where most rivals can barely touch it is when it comes to driving.

Currently there aren’t many electric vehicles that are good to drive, except for more prestige offerings from brands such as BMW, Mercedes-Benz and Porsche. 

The Solterra is one of the best electric vehicles I have driven at this price point and it’s down to the outstanding platform it shares with the Toyota bZ4X which provides superb ride comfort, great handling and excellent steering.

Acceleration is strong and traction from the all-wheel drive is good.

Sure, while the driving position needs improvement, the car itself is excellent to drive.

Visibility is also good and sound intrusion is minimal. We noticed some materials making noises in the cabin. Although this is common, with no engine to mask it, it becomes more noticeable in EVs. 

The Solterra has been awarded the maximum five-star ANCAP rating - but that was given under 2022 testing criteria and the bar has been raised quite a lot higher since then. 

Still, the level of safety technology is high with AEB, lane keeping assistance, blind spot warning and rear cross traffic alert onboard. 

Front and rear parking sensors are standard on both grades, as is a 360 degree camera view. Auto parking is standard on the Touring.

A digital rear vision mirror is also standard on both grades providing a clear and unobstructed view.

There are seven airbags present, including a front centre bag. And there are three child seat top tether points across the second row with ISOFIX anchors in the two outer positions.

The IM6 is covered by a five-year, unlimited-kilometre warranty, rather than MG’S 10-year term. Capped-price servicing is offered for the first five years, with your total bill just under $3000. The service intervals are 20,000kms or 12 months.

The Solterra is covered by Subaru’s five-year, unlimited-kilometre warranty which is falling behind the seven-year warranty offered by many now. The battery is covered  by an eight-year, 160,000km warranty. 

There is also five years of capped price servicing with each yearly/15,000km service costing between $130-$300. That’s a very reasonable price.
