BMW 5 Series vs Gac Aion Ut

What's the difference?

There’s no getting around the i5 being a rather expensive offering. More than $150,000 to get into an electric sedan that’s not much faster than a hot hatch is a big ask, but there’s plenty to enjoy about the 5 Series.

Things like its heated leather seats shouldn’t be the reason you’re willing to spend so much on a sedan when a $50,000 hybrid SUV will score you the same, instead it’s the fact the 5 Series is a delight to drive and hasn’t lost the feeling of prestige the badge has earned over the last half a century.

In terms of value - if speed isn’t your focus and you’re less of a gadget-type-operator when looking at cars like this - the 520i has the style and comfort you’d need and at $100K less than the M60.

And in terms of large electric sedans, the i5 eDrive40 is cheaper than a Porsche Taycan (by a little) or an Audi e-Tron (by a lot). The Genesis G80 Electrified is the closest cheaper rival, by about $10K, or the less powerful Mercedes EQE is similarly priced at $154,900.

Essentially, if you’re looking at a 5 Series, it might be worth considering if you really need it to be electric, but if so, there aren’t many alternatives in its category for the price.

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.

If you’ve watched other members of the BMW family go into a new generation within the last few years - the 3, 4 and 7 Series particularly, you won’t be too surprised by what you see here. Especially with the latter, having seen the petrol variants look roughly the same as the electric ones.

BMW specifically made the petrol 520i and the i5 variants look similar for egalitarian purposes - to not disenfranchise 520i buyers who are still spending a fair chunk of cash but might not be ready to go EV.

That means all three variants score a mix of new and old. The kidney grille remains and isn’t as large as on the M3 or 4 Series, while the bonnet line following it and the ‘character line’ down the car’s side also remain. And yes, the Hoffmeister kink where the C-pillar meets the passenger window’s lower corner is still there.

On that C-pillar though is a ‘5’ stamped into the bodywork, new to this generation, while the front grille as mentioned has a glowing light surround - the brand’s ‘Iconic Glow’ already seen on the 7 Series.

Overall, thanks to being slightly larger in every dimension, the new 5 is starting to look bigger than a 7 Series from a little while ago. And that’s because it is - its body is overall longer than an E65 7 Series from the mid-2000s.

It’s 5060mm long 1900mm wide, 1515mm tall (97mm longer, 32mm wider, and 36mm taller). Its wheelbase is 20mm longer too at 2995mm. 

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.

A longer wheelbase means more space inside, where the 5 Series also still looks fairly familiar to those who have spent any significant time in a recent model BMW.

BMW has historically been pretty bang-on with ergonomics, and the new-gen 5 does a good job of sticking to that. Comfortable sports seats and quality feel for the materials on touch points mean the 5 Series feels nice to be in, and relatively restrained interior design for a somewhat luxurious car means it looks nice too.

It’s let down only by a couple of things - its multimedia screen and Operating System 8.5 is a little less simple to use now, and requires more touching the screen than previous iDrive systems, rendering the scroll wheel less useful.

The BMW Interaction Bar too is a little tricky to see controls on, as well as lacking physical feedback for using controls. Vent flow controls are digital sliders on the Bar, while vent direction is controlled by an unusual ‘joystick’ style control nearby.

The rear seat is plenty spacious, as you’d expect from a large sedan, with climate controls and ports for charging devices in the rear.

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!).

Despite BMW calling it ‘electrified’, the base 520i is only a mild hybrid so most wouldn’t realise unless they were told.

Its turbocharged 2.0-litre four cylinder puts out a modest 153kW and 330Nm, with power and torque sent to the rear wheels via an eight-speed automatic transmission.

BMW claims it’ll knock over the 0-100km/h sprint in 7.5 seconds, a few seconds too slow to blow anyone’s socks off.

The mid-spec eDrive40 has a little more kick to it, its rear-mounted electric motor capable of 250kW/430Nm and able to cut that time to 6.0 seconds.

It’s fitted with an 84kWh battery to draw its power from, the same as the 442kW/820Nm M60 with its all-wheel drive dual-motor setup.

The M-tuned i5 can hit 100km/h in a claimed 3.8 seconds. Bye bye socks, perhaps.

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 claims the petrol 520i sips 6.7 litres per 100km from its 60-litre fuel tank, though we were unable to independently test any of the claimed figures on the launch day.

The base car has a theoretical range of 896km if it was possible to achieve the claimed fuel consumption figure for the duration of the whole tank - but it isn’t and realistically you could knock about 20-30 per cent off that, depending on how enthusiastically you drive.

In the i5 variants, the same 84kWh battery provides slightly different ranges due to the eDrive40 using 16.56kWh per 100km, and the M60 using 18kWh.

The eDrive40 has a claimed 550km maximum range, while the M60 has a 506km figure thanks to its extra motor and weight.

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.

For some cars, the list of features is what really separates the variants, but that’s not the case for the 5 Series. As is a bit of a BMW tradition, the drivetrains dictate the different trim levels and prices, and there are three fairly distinct flavours of 5 Series.

Starting at ground level, the 520i might at first seem like a bit of boring vanilla. Except it’s actually quite smooth and light vanilla.

There’s not a lot to write about when it comes to its drivetrain, but the lightness of its engine and petrol tank combo when compared to EV batteries and motors is refreshing, and makes for a quite dynamic rear-drive sedan.

Its 153kW and 330Nm is delivered smoothly enough with the mild hybrid assistance doing a little in helping responsiveness, but without intervening in the gearshifts it doesn’t feel particularly keen.

It lacks the ride comfort of the i5’s adaptive suspension, but it’s able to be driven in a spirited manner that belies its size and even, to some extent its 1725kg kerb weight. Chocolate sprinkles on the vanilla, if you like.

It’s not fast, but it feels nimble compared to its electric siblings and can carry a fair bit more speed through corners, after which there’s room to notice its rear-drive characteristics.

It’s especially noticeable after getting out of the 2130kg eDrive40, though the extra power from its 250kW/430Nm motor makes for some more spirited acceleration and a little more excitement when exiting a corner, especially if you’re aiming to double-check if it really is rear-wheel drive. There’s a little more than choc-topped vanilla going on here.

The steering is, like in the 520i, direct and responsive, though in most cases is probably best set to ‘comfort’ rather than ‘sport’ in its settings. 

The eDrive40 is rather comfortable and capable when barrelling through twisty backroads, and doesn’t feel out of hand for a five-metre-long sedan. It holds its weight well, and telegraphs when you might be approaching the limit quite sensibly.

When considering that, then, it’s impressive how brutally capable the 2305kg M60 is.

Here, we’re looking at a double-choc fudge with extra choc, and maybe some cookie dough in there for good measure. There’s a lot to like, but boy is it heavy.

It’s 580kg (or exactly half a Peugeot 208 GTi) heavier than the 520i, but it feels quick on its feet and its anti-roll seems to do a lot in terms of dynamics, the limiting factor really seems to be its tyres (which can and will squeal quite quickly to let you know when approaching said limit).

While you’ll need to take caution with how much speed you approach a corner with, you’re not going to lack acceleration on the other side, its all-wheel drive being less ‘fun’ but more efficient at getting you away from the bend than in the rear-drive eDrive40.

That adaptive suspension does also translate to a comfortable ride on relatively rough roads - only particularly bad bumps will reveal how much weight and pressure is being placed on each corner of the big sedan.

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 has a fairly industry-standard five-year/unlimited kilometre warranty on its new cars, while its electric car batteries are covered by an eight year/160,000km warranty.

For servicing, BMW offers numerous discounted packs and deals based on your preferences and desire to pay upfront.

For the 5 Series, a five-year/80,000km basic service package is $2400, though the i5 will have different needs and lower servicing costs not yet listed by the brand.

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.
