BMW 528i vs Gac Aion Ut

What's the difference?

Sleek and attractive in the city,  engaging on a country back road and with plenty of clever technology, the 5 Series sedan ticks all the right boxes as an executive express. If you can stomach the price hike, the six-cylinder 540i is our pick of the bunch.

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.

Hardly a revolution, the 5 Series has instead undergone a few nips and tucks. But if it ain't broke and all that. It might not be the most head-turning offering, but the 5 Series sedan remains sleek, powerful and understated, and it is undeniably handsome on the road.

Its 8mm wider, 28mm longer and 2mm taller than the car it replaces, but it's also around 95kg lighter, thanks to its aluminium doors and boot and a clever magnesium frame for the instrument panel that saved another two kilograms. There's some other clever design elements, too. The kidney grille has active air flaps that open when extra cooling is required, closing when it isn't, reducing drag and helping accleration.

Inside, the 5 Series offers a beautifully crafted yet joyously understated cabin, with quality materials joining modern technology in a seamless way.

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.

This is a full-size sedan, and every seat feels spacious and airy. The sloping, slightly coupe-style roofline does cut into headroom in the back, but human-sized people will have little trouble, even sitting behind a tall driver.

Each trim offers two cupholders in the front, with another two housed in a pull-down divider that seperates the rear seat. And there's two ISOFIX attachment points, one in each window seat in the back. 

The 5 Series' boot opens to rival a surprisingly sizeable storage space, offering 530 litres with the 40:20:40 rear seats in place.

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!).

The hunt for efficiency sees all but the most expensive 5 Series models equipped with four-cylinder engines, including the entry-level 520d, which is fitted with a 2.0-litre diesel unit that will produce 140kW at 4,000rpm and 400Nm from 1,750rpm. That's enough to push the cheapest 5 Series to 100km/h in a not particularly inspiring 7.5 seconds, topping out at 235km/h.

The cheapest petrol, the 530i, arrives with a turbocharged 2.0-litre engine good for 185kW at 5,200rpm and 350Nm from 1,450rpm. That will see you clip 100km/h in 6.2 seconds and push on to a limited top speed of 250km/h.

The turbocharged six-cylinder feels right at home in a car this size, with acceleration effortless and freeway overtaking manoeuvres an absolute breeze.

The 530d introduces the first six-cylinder engine, a 3.0-litre unit that will produce 195kW at 4,000rpm and an impressive 620Nm from 2,000rpm. That's enough to knock off the sprint in in 5.7 seconds and offers a top speed limited to 250km/h.

Finally, the top-spec petrol, the 540i, will produce 250kW at 5,500rpm and 450Nm from 1,380rpm from its 3.0-litre turbocharged straight-six engine. Those are healthy numbers, and enough to welcome 100km/h in a sprightly 5.1 seconds before topping out a limited 250km/h.

Every model is paired with an eight-speed torque converter automatic transmission.

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.

BMW quotes a combined 4.3 litres per hundred kilometres from the 520d, which will also spit out 114g per kilometre of C02. The 530d lifts that number to 4.7 litres per hundred kilometres (which seems a small price to pay for all that extra torque), with C02 pegged at 124g per kilometre. Both diesels get a slightly smaller tank, at 66 litres.

The 530i will sip a claimed/combined 5.8 litres per hundred kilometres, with C02 emissions a claimed 132g per kilometre, while the big 540i requires 6.7 litres per hundred kilometres, with C02 pegged at 154g per kilometre. Both petrol models get a 68-litre tank and require 95RON fuel.

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.

BMW's pre-drive briefing was so technology focused we half expected the black turtle neck and dad jean-wearing ghost of Steve Jobs to emerge from behind a curtain clutching an iPad. Only a minuscule portion was dedicated to the cars' drivetrains, with BMW instead hammering home autonomy functions, technology upgrades and the fact that its car was a preview to "the future".

But once we'd slipped behind the wheel of the all-new 5 Series, it all started to make more sense. Having briefly sampled three models (the 530i, 530d and 540i), we can safely report there's nothing particularly revolutionary about their on-road behaviour. That's not necessarily a bad thing - they do everything you could ask of a car in this bracket. They're mostly smooth and always quiet, the new chassis has done nothing to dampen engagement when you start to ask a little more of it, and it's generally a luxurious experience. But then so was the old car.

But what's new is the technology poured into the 5 Series. Every car gets what BMW is calling its personal co-pilot, for example, which is a set of tricky systems (there's six cameras, five radar sensors and 12 ultrasonic sensors scattered around the car) that work with the active cruise control and allow the car to be driven completely autonomous for 30-second intervals. Now, it's not quite as advanced as some of its competitor's systems - it can't change lanes for example - but if you're out on a country road or on a highway, it will stay within its lane, turn around corners and keep up with the traffic, even if they stop in front of you.

This is a full-size sedan, and every seat feels spacious and airy.

While the cheapest diesel model has historically been the best seller, BMW is hoping the new 530i will prove the most popular this time around. And while you couldn't describe it as fast, the power from its four-cylinder engine is ample for all that will likely be asked of it, and it feels sorted and composed on  more challenging roads. It's a smooth and comfortable ride, too, even with the optional 20-inch alloys fitted, though that's undoubtedly thanks to the adaptive dampers and ever-changing dynamic ride function, both of which are fitted as standard. In fact, we're yet to drive a car without those options fitted, so we're forced to reserve judgement on the as-standard ride quality of the cheaper models.

Be warned though, none in the 5 Series range offer the disconnected and perfectly smooth conveyance you might find in some true luxury offerings, and you'll still know when you're diving into deep pockmarks in the road. But the trade off is a an engaging ride and steering set up that always feels planted, with enough feedback to ensure you feel connected to what's happening beneath the tyres. And that's a trade we're more than willing to make.

Step up to the 540i and things take a much sportier turn. The turbocharged six-cylinder feels right at home in a car this size, with acceleration effortless and freeway overtaking manoeuvres an absolute breeze. And while we didn't find roads quite brutal enough to really test the active anti-roll bars housed at each axle, there's a wonderful and stable flatness to the way the biggest petrol handles corners.

It's not cheap, but thanks to the bigger engine and sorted dynamics, the 540i feels most like a 5 Series probably should.

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.

The BMW 5 Series is covered by a three year, unlimited-kilometre warranty, and requires condition-based servicing (rather than a pre-defined service interval).

You can also prepay your maintenance costs for five years/80,000kms, with prices ranging from $1,640 for the basic package, and climbing to $4,600 for the all-inclusive option.

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.
