BMW 840I vs Gac Aion Ut

What's the difference?

If you’re the sort of buyer who wants a car that signifies a lifestyle that is ‘large and in charge’, the BMW M850i Gran Coupe could be just the thing for you. It isn’t as showy as some of its competitors, and mightn’t reach the same levels of excitement as those cars either - but it is a convincing offering in its own right, and a beautiful piece of design at that. 

The Aion UT is a cleverly-specified little hatchback and a great entry-point into electric motoring. The software needs a bit of work from a usability perspective, plus the spongy ride and cutesy styling might not be for everyone. 

However, with strong points including driving range, cabin space and value, there’s even a pitch for it in some cases to be an only car compared to most of its price rivals, which are more likely to be thought of as a second car runabout in a two-car garage.

The pick of the range is definitely the entry-level Premium. It comes in at a headline-grabbing price with specs to blow rivals out of the water, while only missing out on a few luxuries.

Note: CarsGuide attended this event as a guest of the manufacturer, with accommodation and meals provided.

This could be BMW’s most convincing design in years. I mean, the X5 is predictably handsome, the X3 was unexpectedly muscled, and the less said about the frumpy 1 Series and busy 3 Series (apart from the wagon… drool) the better.

To my untrained but enthusiastic eye, the 8 Series Coupe is a bit too rounded over its rear haunches, and the rear screen is just a little steep - to me, that lets its dimensions down a little. But this. This is gorgeous. 

I mean, you might have questions over the tail-light design, which is a theme across a few BMW models now. But there isn’t as much confrontation between horizontal and vertical graphics for this model as you’ll find one other big Bimmers, like the X7. 

The M850i model has BMW Laserlight headlights, which throw a sharp beam and look menacing in their signature, while the grille and bumper are strong. The stance of the car is prominent - there’s a long body, a long wheelbase, and a long body in general. The standard wheel package consists of 20-inch rims, and they don’t look disarmingly large.

As our images show, there’s a lot to talk about when it comes interior design and finishes, but the cabin doesn’t quite benefit quite as mochas you might think it would from all that real estate. I mean, with dimensions of 5074mm long (on a 3023mm wheelbase), 1932mm wide and 1402mm tall, this is a squat, yet substantial vehicle. It’s just more cramped than you’d think inside.

GAC tells us the UT hatch was designed in Milan, Italy, but it also isn’t ashamed of the Chinese influence on its overall appearance, like the ultra-short bonnet and Chinese city-car style face.

Along the side it has a modern, aerodynamic profile, and the ultra-short overhangs and long wheelbase maximise the amount of room for batteries under the floor and interior space.

The rear feels a lot like a modern Mini, with its bulbous tailgate and protruding light clusters, spiced up with a sporty spoiler piece jutting out.

It’s not a bad looking thing and it’s available in an array of fun colours.

On the inside it seems to follow the established rule-book of Chinese automakers, with plush trims, big screens with minimal physical buttons as well as a contemporary two-spoke steering wheel.

There’s a trendy floating console which hosts the cupholders and wireless charger on the Luxury grade, and an array of interesting patterns and textures through the doors and dash which you wouldn’t have once seen on a car at this price-point.

However, it is worth noting that while the seats are quite nice, and the steering wheel is a stand-out touchpoint, the trims on the doors and across the dash-top are hard plastics, more so than some of this car’s rivals.

I recall a Mitsubishi designer telling me, once upon a time, that he dreamed of making ‘a big car on the outside with a very small interior’. Maybe he made the jump to BMW, because that’s pretty much the 8 Series Gran Coupe.

There aren’t many other vehicles on the market, of this size, that offer less space inside. The boot capacity, for instance, is just 440 litres. Competitors like the Audi A7 (535L) and Mercedes CLS (520L) easily outdo it - but at least this car has more boot than the Panamera (405L), though the BMW is a smidge bigger. The cargo space is large enough for a couple of overnight suitcases, but you’re hardly going to fit a family of four’s luggage for a week away. 

And while we’re in the “not quite what you’d expect” column, the back seat space is hardly commodious. There’s enough space for me, at 182cm, to sit behind my own driving position, but not without wishing for a bit more toeroom, headroom and knee space. 

The big centre console section eats into the space in the rear, justifying the brand’s “4+1” seating claim, and unpleasantly it has a hard plastic finish to rest your leg against. Getting in and out of the second row isn’t easy for bigger people, and it’s quite a squat down into the rear seat - it really has taken inspiration from its squashy-back-seated predecessor in that regard.

If you have smaller rear-seat occupants, however, there will be catered for with dual ISOFIX and three top-tether points, plus there are air vents with climate controls (quad zone in total), and two USB-C ports as well. There are sun-blinds on the rear windows, too, which is a plus, and there is a pair of cup holders in the fold-down armrest, and map pockets in the seat backs, too. The door pockets are near-useless, though.

The front seats score better practicality, with bottle holders in the doors, bigger and sturdier cup holders, a covered centre storage bin between the seats with a USB-C port, and a wireless phone charger (Qi) with standard USB port in front of the gear selector.

Above that is the weird, very out-of-place quick buttons (1-8) that BMW could easily do away with, and further up are the controls for the climate control (thankfully with hard buttons for fan speed and temperature), and above that is the media screen, a familiar looking 10.25-inch touch display running BMW OS 7.0. 

The screen is quick and crisp, and is backed up by the rotary controller and buttons on in the centre console area. There’s wireless Apple CarPlay (now at no cost for three years), as well as a built-in SIM card for 4G data and access to the BMW Online news and weather stations, accessed through the screen.  

It’s all pretty easy to use, and the sound system is excellent - the standard setup consists of 16 speakers, with DAB+ digital radio, Bluetooth and USB plus the smartphone mirroring tech, provided you don’t have an Android device, as Android Auto is still missing from BMW’s range.

It’s a nice cabin, but I couldn’t help but thinking that I’d want a little more differentiation from the lesser models in the range if I was spending this much. Especially considering the optional cost of the interior trim fitted to our test car - see below for more detail.

In terms of interior space, the Aion UT stands out with its spacious cabin. At 182cm tall, I am easily able to find a comfortable seating position, and visibility out the front sides and rear, while not as good as some small SUVs, isn’t bad.

There’s lots of headroom, and while I mentioned the hard plastic door cards before, there’s enough padding everywhere your elbows are going to touch to make it feel a bit nicer than perhaps it is.

The main drawback of this car for me is the lack of tactile buttons and the frustrating software.

The main screen isn’t particularly well utilised, being taken up by either a background or the navigation map, with an array of typically small shortcuts across the bottom for important features like the climate control or settings menus.

You can pre-set a few information panels which sit above the shortcut bar as in many rival cars and there’s also a shortcut tray which can be hosted on the driver’s side and configured with a variety of shortcuts and settings.

It’s just a bit clumsy to use, and the array of poorly-labelled settings menus for things like active safety equipment feel needlessly complicated.

I’d love to see this car with physical controls for climate and multimedia to make it easier to live with.

Up front the storage is decent. There are big pockets in the doors and a large storage tray between the driver and front passenger thanks to a flat floor. There’s also a slightly weird storage box under the touchscreen which has a net inside, good for more delicate objects you don’t want flying around the cabin.

On the floating console there are two cupholders which are a bit too shallow for my liking, and the wireless charger feels almost pointless because its made of a hard plastic, so your phone just slides right off in the corners. The cabled outlets are hidden beneath which allows for tidy cable management and the centre armrest console box is a healthy size.

The rear seat is comparatively basic, although touches on the key points. Its main advantage is how generous the space is. My frame was able to fit behind my own driving position with heaps of room for my knees, and just enough room for my head despite the dip in the roof for the sunroof shade in the Luxury-grade car we tested. There may be even more headroom in the base car.

The flat floor makes the space useful even for three across in a pinch and there’s a drop-down armrest with (again, shallow) cupholders. There are pockets on the back of both front seats and smallish pockets in each door. The array of soft trims continues, too, and the back of the centre console features a partially adjustable air vent. Luxury spec cars get a single USB rear power outlet.

As with many Chinese cars in this segment, the generous rear seat space comes at a cost to the boot. It measures just 321 litres, which is slightly smaller than its main opponents in this category, although larger than some hatchbacks like the Toyota Corolla, for example.

It has its advantages, though. The floor is two-tiered, and can offer a flat load area with the rear seats folded down, or a deeper boot in its lower position. Underneath there’s a cutaway good for charging equipment and the tyre repair kit (sorry, no spare wheel in here).

Unlike some EVs, the Aion UT doesn’t get a frunk (front boot) for additional storage.

The GAC Aion UT starts from $31,990, before on-road costs, for the entry-level Premium grade, which makes it the third-most affordable EV you can buy in Australia after the city-sized BYD Atto 1 and the entry-level version of the BYD Dolphin.

It sits closer to price-parity with the GWM Ora, but is significantly more affordable than the rear-drive MG4 and more spec-competitive top-grade BYD Dolphin.

The bigger threat to the Aion UT is that a lot of buyers will be willing to spend slightly more to get into one of the most affordable electric small SUVs, like the BYD Atto 2 or Jaecoo J5.

Still, GAC makes a solid pitch for its hatch, which offers a higher spec level than its most direct price rivals.

For example, the Aion UT is more powerful than the entry-level Dolphin and Ora while offering a higher level of interior equipment. 

Even the just-arrived front-drive MG4 Urban also starts at $31,990, but that’s for a version with significantly less driving range.

In fact, I’d go so far as to say the entry-level version of the Aion UT (the confusingly-named Premium) is probably the pick of the two variant range.

Standard equipment levels on this car include 17-inch alloy wheels, LED lighting all around, synthetic leather interior trim with heated and power adjust front seats, a 14.6-inch multimedia touchscreen with online connectivity and built-in nav as well as wireless Apple CarPlay and Android Auto.

There’s also an 8.88-inch digital instrument cluster, heated steering wheel and the full array of safety kit.

With the same power and battery size, this leaves only arguably unnecessary luxuries for the Luxury grade, like a wireless phone charger, ventilated driver’s seat, auto dimming rear vision mirror with auto power folding wing mirrors, a powered tailgate and of course, a panoramic sunroof (with shade!).

If you’re going for the M850i, you’re getting the big bopper engine. It’s a 4.4-litre twin-turbo V8 petrol engine, and it isn’t short on horsepower.

The outputs for this engine are 390kW of power (at 6000rpm) and 750Nm of torque (from 1800-4600rpm). Hardly numbers to sneeze at.

And the performance figures are exceptional, too: the claimed 0-100 km/h time is just 3.9 seconds. That’s because there’s the traction of BMW’s xDrive all-wheel drive system, and shifting gears is an eight-speed automatic transmission.  

For what it’s worth, your humble reviewer saw a 0-100km/h time very close to that (4.2sec). 

The quoted kerb weight for this model is 1995kg.

The Aion UT has a front-mounted electric motor producing 150kW/210Nm. That’s plenty punchy for any hatchback at this price, and I like the way the brand hasn’t messed around with a sub-100kW motor in the base variant to push prospects towards the top-spec car.

It’s more powerful than all of its closest rivals and at the time of writing you’ll have to spend four to six thousand dollars more to get into something equivalent from BYD, Chery, Jaecoo, Leapmotor or MG.

It even has a claimed 0-100km/h sprint time as low as 7.3 seconds.

You can’t really expect a big V8 beast like this to be a fuel miser, and it isn’t.

The claimed consumption is 10.7 litres per 100 kilometres. Which is alright, honestly, given the sheer volume of car you’re driving. 

But on my test - which consisted of more than 300km of mixed driving, including days of city commuting, some twisty mountain driving, and all the freeway floundering to get there - I saw an at the pump real-world figure of 15.4L/100km.

That’s not very efficient, and it’ll be expensive to run on the daily — yet the argument could be made that if you’re spending this much on a car, fuel costs won’t matter much to you. But with a small fuel tank capacity of 68 litres, it could become a little inconvenient as you’ll be seeing a lot of your local servo.

The Aion UT has a 60kWh lithium-iron phosphate (LFP) battery pack, which grants it a WLTP-certified 430km of driving range.

That’s more than its closest rivals, like the entry-level Ora Standard Range (310km), BYD Dolphin Essential (410km) or BYD Atto 2 (345km).

Claimed efficiency is 16.4kWh/100km and the car I tested returned a consumption of 14.0kWh/100km over a 130km route of mixed conditions, which isn’t bad at all.

Charging speeds are less impressive, but realistically appropriate for the relatively small battery. The peak DC charging capacity of 87kW means a charge time which the brand quotes at 24 minutes, but this is from 30-80 per cent. Expect closer to 40 minutes for a 10-80 per cent charge.

AC charging is decent, at 11kW. This should have you charging from 10-80 per cent between four and five hours.

It’s an impressive thing, this M850i xDrive Gran Coupe. But I’m just not sure who it’s trying to please.

It’s not the sort of German monster coupe-sedan that grabs you by the scruff of the neck and throws you around with its mammoth acceleration. Not unless you poke it and prod it and make it really angry.

And that might be exactly what you want to do - put it in Sport mode, sling the shifter across to sport or manual mode, hear the exhaust open up from a pursed-lip tongue-click to an open-mouth growl. 

You’ll push hard on the accelerator, watch the tacho needle jolt to the redline, and if you’re in auto mode you’ll feel the transmission whipcrack as it shifts rapidly up through the gears as you’re shoved back into your seat. Before you know it you’ll be in licence-loss zone, and you won’t have even made the tyres chirp - that’s how immense the traction from the all-wheel drive system is.

You’ll brake hard into a sharp bend, and you’ll feel the front end dip and the body of the car change direction more readily than you’d think given its size as you turn in. The steering response will meet your expectation, with rapid reaction to adjustments mid corner. And the Active Roll stabilisation system will mean you’re not being thrown around in your seat, because it’s sitting flatter and truer than you might have expected - you’ll notice how it works extremely well in conjunction with the car’s torque-vectoring-by-braking system. There’ll be little weight shift or body roll to be counteracted, and that’ll inspire you to push it even harder.

Put it in manual transmission mode and you’ll rejoice that it won’t overrule you and shift up, but you’ll also feel shortchanged because it gets to the end of its limit very quickly. And when it hits redline, it emits a breathless little cough rather than a “oh maybe I should stop” rev-bounce noise.

But, if you’re like me, you might be doing all this with a niggling thought in the back of your mind that, while this car is technically really good and it’s a clinical performance car, you might just think to yourself, “I’m not having as much fun as I thought I would”.

A Mercedes-AMG would be more fun; it’d be more raucous, more of a muscle car experience. An Audi RS7 (at least the previous one) would be noisier, brasher, more theatrical than this car. And likewise, a Porsche Panamera - no matter the model you go for - would be more entertaining in the bends.  

Maybe it’s just a bit too predictable - and maybe that’s a result of this car being honed for drivers who will spend more time on the Autobahn than anywhere else. I have to say, there are much, much worse (and slower) ways of getting from A to B, and the highway cruising comfort of the M850i Gran Coupe was what impressed me most. 

It’s also surprisingly adept at urban driving duties, coping well with unpleasant city surfaces, though potholes can still upset things because of the stiff-sidewalled run-flat tyres. The suspension does an exceptional job otherwise, however, and I switched between the Adaptive drive mode and Comfort mode for my commuting duties. Both proved comfortable and controlled.

The M850i is by no means a failure when it comes to fulfilling the expectations you might have of a luxury sports sedan of this size. In fact, it’s close to a distinction. But I just can’t help thinking that it’s not as much an ‘M car’ as that M850i badge might have you believe it should be.

The drive experience can be where a lot of Chinese cars fall down but I walked away less frustrated by the Aion UT.

That’s not to say it will behave as you might expect a low-slung hatchback to. The suspension, for example, is extremely soft as it maintains its original Chinese-market state-of-tune.

This makes the car waft over imperfections on city roads. And in that sense it offers supreme ride comfort in the scenarios it was designed for. However, at the extremes, like some speed bumps, or particularly deep pot holes there can be a surprisingly violent re-bound sending a thud through the cabin.

The other trade-off for soft suspension is less body control. I was surprised to find that the Aion UT holds it together mostly well on a flat country B-road, but when undulations and big dips introduce themselves, the soft suspension can be too slow to react, making the car lose confidence in higher-speed open road scenarios we’re more used to in Australia.

The steering, like many electric cars in this category, is relatively heavily electrically assisted. This makes it light and easy to adjust at low speeds for easy park and maneuverability in the confines of a city. It loses a little bit of road-feel at higher speeds but the Aion UT’s steering is far from the least connected I’ve experienced recently.

One thing it can’t be criticised for is a lack of power. With 150kW instantaneously available the Aion UT has some serious poke and while the ChaoYang tyre package is tuned more for efficiency than grip, it’s again not one of the worst I’ve driven with.

One thing which helps the whole experience along is this car’s hatchback layout. With the weight of the battery low and squat and the wheels all the way out to the edges of the frame, the Aion UT inherently handles decently compared to an electric crossover or small SUV.

Like all Chinese cars, the UT has a host of occasionally frustrating driver aids, which you can read about in the Safety section below. While I was inclined to turn some of the features off after testing them, the alerts are relatively quiet and non-invasive.

Is the UT any good to drive? It’s not bad for the segment, I was largely pleased with how it handled and the power on offer, and while it still has its annoyances, they’re not big deal-breakers. 

The MG4 rear-drive is a better allrounder, while the GWM Ora isn’t as good. I’d say it’s on par with the BYD Dolphin, but they excel in different areas. The Dolphin's a bit sharper in terms of handling but the Aion UT is more comfortable.

As with many Chinese cars the list of active safety equipment is long but that doesn’t mean it’s particularly well calibrated.

Standard gear includes the key stuff like auto emergency braking (AEB), lane keep assist, blind-spot monitoring, rear cross-traffic alert and adaptive cruise control. There are also rarer features for an affordable car like this including traffic sign recognition, door open warning, auto high beams and front cross-traffic alert.

On the parking front you get a 360-degree parking camera view as well as front and rear proximity sensors.

There's also an annoying driver monitoring system and one I haven’t seen much in the form of an occupant warning system, which seems to imagine you’re not wearing a seatbelt when you are.

It’s not the only safety system I found myself reaching to turn off. The lane keep assist could occasionally be a bit heavy-handed and the traffic sign alert was typically frustrating. This, sadly, is what we’ve come to expect from these types of systems from many Chinese automakers.

It’s not the most annoying system I’ve used, though, and the alerts are quiet enough and far enough apart that they aren't as intrusive as they can be in some rivals. You can also adjust the tolerance of some of the systems in the (needlessly complicated) menus to make them less annoying.

At the launch, the Aion UT was yet to be rated by ANCAP.

BMW backs its cars in Australia with a three-year/unlimited kilometre warranty.

You may be confused if you head to the BMW site and see that M models and 8 Series models aren’t covered by BMW’s pre-pay capped price servicing plan (as I saw when testing this car), but CarsGuide can confirm that the 8 Series is indeed covered - unless it’s the real M8, not this M850i jigger. 

BMW Australia has clarified that the Service Inclusive pack for five years/80,000km of maintenance cover is $2490 for Basic cover (no brakes/pads, no wiper replacement), or $5641 for the more comprehensive Plus pack. Hardly affordable, but nor’s the car. 

The company uses a condition-based servicing program, too - there are no set service intervals, but the car will tell you when it needs maintenance based on how you drive it.

For what it’s worth, we ran the numbers on resale value using Glass’s Guide predictive analysis tool, and after three years/40,000km the expected retained value for this version is approximately 66 per cent - which is impressive.

GAC covers this electric hatch with an eight-year and unlimited kilometre warranty, while the brand’s “magazine battery 2.0” is covered by a separate eight-year and 200,000km warranty. Five years of roadside assistance is included.

The Aion UT needs to be serviced once a year or 15,000km. The service price schedule extends all the way out to 240,000km with yearly visits costing between $199 and $640 but for the life of the warranty the average yearly cost comes in at $352.

There are currently 19 GAC dealers in Australia, confined mainly to Melbourne, Sydney and Brisbane with a single store in Perth and an outlier in Cairns. No representation yet in Tassie, Canberra, the Northern Territory or SA.
