The Mini brand had a busy 2024, but the car to which we now turn – the Mini Aceman – may well be its most important development among so many renewed siblings. That’s because the Aceman isn’t quite a natural successor for the short-lived Paceman three-door crossover of 2012, nor is it a differently named follow-up to the slow-selling Clubman pseudo-estate.

It is, instead, a new kind of Mini intended to perfectly plug the gap that has started to appear between the core Cooper hatchbacks and the C-segment-sized Countryman.

And if it seems to assume something of a key significance, that may be because it is the scion of the Aceman concept which, back in 2022, gave us our first flavour of Mini’s current design language.

This is the car that aims, more than any other, to perfectly fuse trademark Mini dynamism and desirability with more pragmatic usability. Built exclusively by Spotlight Automotive (the BMW Group’s joint venture with Great Wall Motor) in Zhangjiagang, China, it is also the only model in Mini’s showroom catalogue to be exclusively wedded to electric power.

DESIGN & STYLING

MINI Aceman review 2025 002 panning

The Aceman is a four-metre-long, supermini-sized, jacked-up crossover hatchback, then, intended to rival anything from a Volvo EX30 to the recently announced Ford Puma Gen-E.

It is, in a rather simplistic sense, a stretched Cooper electric hatchback made on the same Chinese production line as the three-door-only supermini. Compare the dimensions of both cars and you will find that the Aceman is 80mm longer in the wheelbase than the Cooper, 221mm longer overall and just 54mm taller, making it small and fairly low-rise by B-SUV class standards. Standing next to one, you might simply take it for an only averagely large ‘regular’ supermini that just happens to be wearing its hiking gear. 

Go for Rebel Red paintwork and you can have a matching roof, or a contrast roof in either black (as fitted) or white. A 'Blue Multitone' roof, which fades from dark towards the rear to light at the front, costs £650.

Given the established technical relationship between the Cooper and Aceman, much of the rest of the mechanical content follows suit. It’s driven by one of the BMW Group’s favoured separately excited synchronous motors and, just as with the electric Cooper, that motor can supply 181bhp (Aceman E), 215bhp (Aceman SE) or 255bhp (Aceman JCW) to the front wheels, depending on how much zip you want your mid-sized Mini to command.

Drive battery packs are shared with the electric Cooper, too. And so, while the kind of money that Mini is asking for some Aceman models will get you close to 80kWh of usable battery capacity or more from other compact EVs, in this one you get less than 50kWh (SE, JCW), or only 36.6kWh in bottom-rung E form. Our SE test car came with a WLTP range of 244 miles, in a class where 350 miles and more is available. ‘Short-range and nippy’ may be a look that an electric Cooper hatchback wears comfortably enough, but on a new derivative that’s supposed to bring extra dimensions of usability, it doesn’t sit quite so well.

Like the smaller Cooper, the Aceman uses all-independent suspension, coil springs and conventional passive dampers. Mini has chosen ‘preloaded’ antiroll bars for tight rein on body roll and the usual direct steering rack, which we recorded at just 2.3 turns between locks. 

Should all of that make it ready to entertain better than rivals? Well, our Aceman SE was 1756kg on the scales, compared with the 1587kg Fiat 600e, 1739kg Kia Niro EV and 1779kg single-motor Volvo EX30. So staying small may have been an understandable plan; but it doesn’t actually seem to have made the Aceman especially light.

INTERIOR

MINI Aceman review 2025 010 dash

So just how much bigger than a regular hatchback does this Cooper-derived modern ‘Maxi’ feel on the inside? In some ways, not much. Entry is via a driver’s door aperture that bigger adults are likely to consider snug. With the seat slid back far enough to make room for longer legs, you will find the B-pillar suddenly in your way as you squeeze in and out, and the roofline close enough to clout your head on if you’re careless.

The hip point and driving position do feel that bit higher than the tea tray-like Cooper’s, of course, though still far from high in general terms. And the fascia is a familiar one. The textile dashboard covering and airy feel are quite lounge-like, and the ‘designer’ neatness of the layout is delivered alongside an apparent charm that’s alternative and appealing.

Door-card design is one of the interior’s bigger points of difference relative to other Minis (which, itself, tells you a lot). The free-standing interior grab handle is at least easy to grab; the faired-in door release isn’t.

Few would mistake this for anything other than a premium interior; it’s just not a significantly different one than a Cooper SE has. The Aceman gets chunky free-standing interior door handles of its own, and a decorative leather strap in a different place to the one on a Cooper.

Meanwhile, the way the central, 240mm, side plate-sized OLED multimedia display doubles as an instrument screen and heating console won’t meet everyone’s approval (see ‘Multimedia’). Underneath it, Mini provides a rather tiddly transmission lever; a mostly superfluous faux engine start key (which you might wish wasn’t there the first time you forget to turn it without first having configured the car’s ADAS features, and then having to go back to square one); and some useful physical audio controls and menu shortcuts.

When it comes to practical touches, the centre storage console that runs all the way through to be accessible by rear-seat passengers is a neat idea, and the moulded plastic accessory docks on the front seatbacks, though ugly, are likely to be appreciated by those in the back.

The boot gets 300 litres of space, so will be fine for a lightweight buggy or a couple of cabin bags, and the seats fold in a 60/40 split if you need them to, but the Lexus LBX has usefully more space with its 400-litre boot, and the Kia EV3 (granted, also a chunkier car at 4.3m long but available at a similar price) is way roomier for passengers and luggage, not to mention has a longer driving range.

According to our tape measure, the car offers head room that’s just about class-competitive, but it lags behind a Smart #1, Cupra Born and Kia EV3 for rear leg room. It’s not as tight in the back as some B-SUVs (Volvo EX30, Jeep Avenger, Fiat 600e), and is probably practical enough – just – to feel like a step up from a Mini Cooper five-door.

But you still wouldn’t really want to be the adult who regularly had to travel in the back of one.

Multimedia - 3.5 stars

The Aceman’s 240mm circular multimedia system, the same as in both a Cooper and Countryman, sets it apart from other BMW Group relations. You navigate it similarly to how you might an equivalent in a BMW 1 Series or X1, though: without the help of a physical cursor controller, but aided by some useful shortcut keys and quick-access menus (the car’s ‘toolbelt’ user-customisable shortcut menu can be set to pop up when you press the star button on the steering wheel).

It’s important to set up a Mini Connected online user account before you do anything else, and then download it to the car (a two-minute process). Otherwise, you will have to reset everything – from the head-up display position, to your preferences for navigation mapping and ADAS settings – every time you start a journey, and the car’s voice recognition also won’t work. But once you have, the pre-flight rigmarole and general irksomeness of the tech is much reduced.

Without any cursor controller, the system is a bit more distracting to operate while driving than it might be, but it is by no means terrible on that score once you’re familiar with it. Mini’s insistence on making the central screen carry instrumentation as well as so much else does frequently draw your eyes further away from the road than necessary. The head-up display, which addresses that problem fairly well, should be standard on all models (it comes with the Level 1 option package on an Aceman E).

ENGINES & PERFORMANCE

7
MINI Aceman review 2025 022 motor

The Aceman’s ‘Mini Sound’ propulsion noise is another good reason to sign up for a Mini Connected user account. It otherwise defaults to on – and you will probably either love it or hate it. It’s not uninteresting to listen to – quietening down and amping up with throttle load, at least, so that it’s not a permanent presence.

The car has fairly strong outright performance by the broadest standards of the class, but whether it’s quite enough to make the Aceman SE stand out among EVs, even at this price point, is questionable. 

On a very chilly day and in slippery test conditions, it just about dropped below the 7.0sec-to-60mph mark but finished on the wrong side of that rubicon to 62mph. The class average for a sub-£40k electric compact SUV is probably nearer eight seconds, but we have tested some that needed less than six to reach 62mph. The Aceman certainly can’t claim to be the zippiest car of its kind, then, even if there is a JCW model coming for those who want more punch. The car took almost full power from rest, so we would estimate that the conditions cost it no more than a tenth or two.

Being an EV, drivability is entirely simple, although regen control is buried in a touchscreen menu. Adaptive mode (which can feel strange as it suddenly adjusts regen with the changing traffic situation in front of you) is the only way to get the car to coast freely when the road is open, and conserve momentum, and it’s just not accessible enough to activate opportunistically. That’s why an increasing number of EV makers use paddles for quick manual control, and BMW and Mini really need to get on board.

Traction is okay in the dry; less so in slippery conditions, in which the car leans a lot on the ESC (which itself feels quite subtle and well developed). The Aceman’s dynamic vibe is certainly not an assured, easy-going one, but then that sense of boisterous, barely controlled enthusiasm is all part of the schtick.

Strong brakes, activated through fairly consistent pedal feel, complete the picture here – and they resist fade quite well. During our track testing, the Aceman’s electric powertrain also itself resisted fade during five fast laps, which was a problem the old Mini Electric had. It also showed a little performance drop-off below 10% state of charge, tapering as the reserves fell further, but not by a punitive amount and only after warning the driver.

RIDE & HANDLING

7
MINI Aceman review 2025 023 panning

The Aceman feels very much more like a proper modern Mini to drive than a typical compact SUV, and in that respect the car’s creators can - and probably will - consider it a dynamic success.

Where the Countryman left us a little unconvinced by its slightly incoherent pairing of enlarged size and feigned-feeling agility, the Aceman’s on-road character comes together better. It’s firm, busy and interactive; a two-hands-on-the-wheel, both-eyes-on-the-road type of drive. Quite fun to take to task, but also feisty and lively enough to give you plenty to do in the act of driving it with some gusto – and quite likeable for it.

There’s plenty of fidget and fight about the handling and steering as it is. Add the JCW’s extra power and torque, stiffer springs and anti-roll bars, and bigger wheels, and it might well tip over the edge of ‘entertaining’ and into ‘annoying’.

The car pulls it all off by feeling moderately compact, and at least fairly agile and light on its feet. It has quick, heavyish steering, with plenty of feel and feedback, which does come with some inevitable torque steer and the occasional snatch of tramlining, though nothing troubling provided you’re anticipating it. You can also feel the car’s brake-based electronic torque vectoring feeding back through the driven front wheels when tackling tighter bends, which, because it’s fairly subtly done and typically works to your advantage, isn’t so intrusive. Somehow, Mini manages to make even this feel like part of the car’s puppyish entertainment act.

The comfort levels some might expect of a daily-usable five-door hatchback are, of course, only present in qualified terms. The ride is a little restless and excitable on country roads especially, but it does settle down at least fairly well on smooth motorways, and it isn’t especially noisy. We have previously tried a less powerful Aceman E, a car you might expect to be less highly strung but in which the ride was actually more fidgety. The extra weight of Mini’s bigger battery might actually help tie this car down a bit better.

It's also worth pointing out that the Aceman’s turning circle of 11.1m is underwhelming for a small car. A lot of rivals, including the Jeep Avenger, Kia EV3 and Lexus LBX, manage closer to 10.5m.

Assisted Driving - 4 stars

This car may be small, but it’s not short of digital convenience features. Though our test subject didn’t have it, the Level 3 options package brings with it a Parking Assist Plus system that will allow you to exit the car and move it into or out of a tight parking bay via your smartphone – not the kind of feature commonly seen on cars at this size and price.

There’s plenty of configurability with the various ADAS features, which, with the exception of the mandatory-on speeding alarm and lane keeping systems, stay as you left them. The former is easy to switch off via a long press of the cruise control ‘set’ button, and control for the latter is ‘savable’ in your toolbelt shortcuts.

There’s driver monitoring too but, unlike in Volvo’s EX30 for example, it doesn’t seem overly sensitive and won’t castigate you for looking momentarily over towards the centrally located instruments. If you happen to leave the lane keeping on, meanwhile, it doesn’t intrude until you get up to quicker out-of-town speeds.

MPG & RUNNING COSTS

6
MINI Aceman review 2025 001 front cornering

Cooper E and SE buyers have to find less than £2000 to open up ownership of the bigger five-door Aceman, which doesn’t sound like much. It starts at £31,800 for the E, £36,300 for the SE and £40,800 for the JCW, but Exclusive and Sport trim levels bump the price up, so the average owner should probably expect to spend between £3000 and £4000 on the top.

Range and DC rapid-charging speed might be disappointments to Aceman buyers who have parted with so much cash. It doesn’t really extend the repertoire of Mini’s smaller hatchback for longer-distance use. Mini claims 192 miles for the cheaper Aceman E, and 244 miles for our mid-level SE, but we didn’t reproduce that. The SE averaged 162 miles in mixed testing, slightly less at constant motorway speeds and only just beyond 200 miles in our low-speed, urban-and-commuting ‘everyday’ efficiency test. Even the decidedly short-legged Volvo EX30 and Fiat 600e did better (although neither was tested in such chilly ambient conditions).

Rapid-charging speed is pegged at 75kW for the cheaper Aceman E and 95kW for the SE and JCW – which looks poor next to what else your money might buy. Our SE test car did respectably well in our rapid-charging tests, with a weighted average speed of 70kW, but, again, rivals do better.

VERDICT

7
MINI Aceman review 2025 027 front static

The Mini Aceman may be supposed to split the difference between the Cooper and Countryman, but - for good and for ill - it feels much closer to the former than the latter. That’s because it has relatively little more practicality, versatility or range than the Cooper, but it also retains plenty of little-car agility and impish dynamic fun factor.

This might actually be a right-sized electric Mini crossover. If this was the last Mini in existence, you could just about use its DNA to reconstruct a true picture of the firm’s modern dynamic identity. Not, perhaps, in terms of its powertrain, but certainly for its ride and handling, which feel entirely authentic.

By class standards, however, the Aceman should be more spacious, more efficient, go further on a charge, and arguably cost less after key options. For all that, it’s easy to see why you’d still go for it. Because the Aceman is, well… a Mini. The interior is second to none in this class for perceived quality, personalisation and sheer wow factor, and it’s also the zingiest to drive in this class.
