Mini Aceman vs BMW I3

What's the difference?

In many ways - range, performance and purchase price, for instance - the Mini Aceman is decent value, somewhat par for the course and would give its logical competition a proper marketplace run. But it’s better than that. The car’s big point of difference is its retro charm and the fact that it’s been tuned to be a fun drive rather than the non-confronting experience some carmakers strive for.

The performance is strong and the handling and steering serve up a bit of entertainment as well as giving the car a particular flavour. Which, as electric drivelines threaten to homogenise cars even further, must count for something.

Yes, some of what you’re paying goes towards that arguably nebulous notion of 'driving-spice' but once you’ve driven it, you’ll probably know what we’re talking about. A new car purchase is always special, so why not make that specialness last a bit longer with a car that will still be an entertainer long after the showroom thrill has worn off.

Meantime, it’s easy to see why Mini has already begun to run-out stocks of the cheaper E model. The SE still manages to play on that cheeky charm, but offers a more mature vehicle into the bargain. Not a bad trick, really.

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

Yes, it’s pricey for a small hatch, but this little BMW is a city car like no other. The i3s is tailor made for the urban environment, and six years on retains the quirkiness and charisma that stood it apart at launch, and it can still hold its head high among the current EV crop. 

Though vaguely retro on the outside, the real nostalgia hit comes when you step inside the Aceman.

The huge, round central display that’s been associated with the Mini brand since day one, returns, but this time in 240mm, OLED screen form.

The display is also where you get to choose how the instrumentation and information looks, with configurable display incorporating a total of eight modes that alter the colours, sounds and visuals of the screen. Is it cool? Er, yes, actually.

There’s also the Mini personal assistant at your service to crank up the heat when you’re cold and switch on the air conditioning when you’re not (all voice activated) and the personal assistant can also learn stuff such as knowing particular navigation co-ordinates mean you’re at the entrance to an underground car-park, at which point the car will wind down the driver’s window so you can flash your credit card. If you think about it too hard, that’s going to be more creepy than cool for some of us.

The move to electrification, of course, is environmentally driven, so the Aceman’s ethos leans into that, too. There is, for example, a complete absence of leather or chrome, the alloy wheels contain as much as 70 per cent recycled material and are produced with renewable energy.

The floor mats, floor structure and interior surfaces are made from at least 90 per cent recycled polyester, and Mini claims a 98 per cent reduction in greenhouse gases compared with the same stuff made from leather.

Built around a carbon-fibre reinforced plastic (CFRP) tub, the i3s is ultra-light (for a battery-electric vehicle), super strong, and unlike anything else on the road.

At just over 4.0m long, close to 1.8m wide, and a fraction under 1.6m tall, the i3s is compact, upright, and boxy. A classically polarising design, with some crossing the street to avoid it, and others (like me) loving its unique proportions and stand-out styling.

The nose is tall, short and upright, with the distance from the base of the front windscreen to the front axle (car designers call it the ‘dash-to-axle ratio’) unusually short.

That’s because the electric motor sits in the back of the car driving the rear wheels, with only a small front boot compartment required to house charging cables and other bits and pieces.

Despite the lack of anything of substance behind it, BMW’s signature ‘kidney grille’ is present and accounted for, with swoopy LED headlights (and DRLs) either side. Our test car’s ‘Fluid Black’ finish with ‘i Blue’ highlights dialed up the little car’s charismatic personality.  

One of the i3’s most impressive party tricks is its counter-opening ‘clamshell’ doors, and the engineering trickery used to create a B-pillar free side opening (including the strength of the carbon body structure) means the high window line follows a jagged path from front to back, the rearmost hatch windows shrinking the rear glass area appreciably.

The i3s’s standard 20-inch (dual) five-spoke alloy rims, although slightly wider in this performance model, are alarmingly skinny. But taking the car’s relatively light weight (1245kg) and urban-centric purpose into consideration, the narrow, low-rolling resistance rubber makes sense.

With the roofline and sides of the car tapering distinctly towards the back, the rear view is suitably idiosyncratic, highlighted by flush-fit, vaguely U-shaped LED tail-lights. 

The hatch window is small, and the bumper sits high to marry with the load space floor sitting on top of the motor and transmission.

And when it comes to moving inside, BMW offers a choice of three ‘interior worlds - ‘Loft’, ‘Lodge’, and ‘Suite’ - featuring renewable natural fibres, recycled plastics, naturally tanned leather, and open-pore wood (sourced from 100 per cent Forest Stewardship Council-certified forestry).

But irrespective of where everything comes from, the end result is inviting, comfortable and sub-zero cool. Our car’s ‘Suite’ interior was combined with ‘Oak dark matt’ wood, and ‘Vernasca’ brown leather to stunning effect.

A tunnel-free floor, gently curved dash and digital screens for instruments and media let you know you’re in something different and special. It might be six years old, but the i3 still feels contemporary and distinctive. 

Perhaps it’s the packaging designed to play the retro card, but I can’t help feeling the door openings on this car are pretty tight. The rear doors, in particular, seem designed for someone smaller than I, and even once I’m in the news doesn’t really improve.

The Aceman’s rear pew seems tight for both foot and legroom and should you have an adult in the back seat, they’re only going to fit by having somebody smaller in the front seats. The chances of a six-footer (183cm) sitting behind a driver of similar stature are pretty slim (over a distance, anyway).

This is all to do with Mini keeping the overall length of the car to just over four metres, and stuffing a compact SUV into that space.

Perhaps that also explains the giant blind spot formed by the thick B-pillar. Either way, taller drivers will find themselves peering around it when crossing or tuning into intersections.

The seats themselves, however, are quite charming. They look a bit small with their cloth trim, but in reality, they’re comfy and supportive. The pleated John Cooper Works front seats that are standard in the SE are phenomenally good. The only thing missing is that distinct smell of leather we’d normally associate with a 60-grand car.

The traditional row of toggle switches under the central screen remains… sort of. These days, they’ve been modified to act as the starter button for the keyless start system and also the gear selector. The problem is that they’re gloss black on a black background, so they can seem a bit indistinct.

The gear selector has also been reinvented – again – with a separate Park button now to the side of the toggle. The other ergonomic glitch I noticed was every time I went for the interior door handle to leave the car, I fumbled for a second till I located it, tucked up under the armrest.

The clean, uncluttered dashboard means a couple of items have moved to the space between the front seats. So, there’s a pair of cupholders, a small, lidded compartments and a pair of USB charge-points all living in the real estate between the front chairs. That’s in the SE, anyway, because the cheaper E retains only the cupholders.

The luggage space is deeper than a lot of EVs manage and the rear seat folds 60/40 to open up a huge area if you don’t need the seats. With the rear seat up, there’s 300 litres of capacity and, with the seat folded, that leaps to 1005 litres.

There are three child restraint tether points, and the luggage space is served by a 12 volt socket.

There’s also a luggage cover that can be quickly removed for taller items. The tailgate is manually operated.

There are also three ISOFIX attachment points for child seats; two on the rear seat and one on the front passenger seat.

Wide-opening clamshell doors make getting in and out of the i3s a breeze. But bear in mind you have to open the front door to get to the latch for the back one, which can be a pain.

The driver and front passenger enjoy heaps of room, in an open environment, but there’s only a single cupholder in the centre console, so let the coffee cup wars begin.

Aside from that there are seriously big bins in the front doors, a modest glove box, and a handy elasticised pocket near the floor at the base of the bulkhead.  

Outlets for 12-volt and USB are provided, and there’s a small oddments tray at the rear of the centre console.

Slip around to the rear and you’re in anything but limousine territory. Sitting behind the driver’s seat set for my 183cm height, head and legroom are modest but do-able. And remember it’s two seats only back there.

In terms of storage, there are two cupholders between the seats but no storage pockets or bottle holders in the doors. You won’t find adjustable ventilation outlets either, but that’s not a huge factor in car of this stature.

The boot’s volume is quoted at 260 litres with the 50/50 split-fold rear seatback upright, which is enough to easily swallow the largest 124-litre suitcase in the CarsGuide three-piece set. The smaller 95- and 36-litre cases will sit side-by-side without a problem.

Fold the rear seat down and you have 1100 litres of space at your disposal, with tie-down anchors, an elasticised pocket and 12-volt power provided.

Don’t bother looking for a spare of any description, a repair/inflator kit is your only option. And not surprisingly, the i3 is a no-tow zone. 

For a compact, four-seat hatch the BMW i3s is all the money at $70,900, before on-road costs. Close to $20K more than even the top-spec ‘Premium’ version of Hyundai’s Ioniq electric hatch ($52,490), and even further away from Renault’s cute little Zoe ($49,490).

But a carbon monocoque body and high-tech powertrain don’t come cheap, and that’s where BMW’s ‘i’ model program has seemingly run out of juice.

Getting into the EV market early, BMW took a punt on niche vehicles using exotic materials, appealing to a relatively small group of premium buyers. And in glorious hindsight, that path has proved something of a dead end.

But putting all that to one side, it’s fair to expect a generous standard equipment list in a $70K-plus BMW, and the i3s comes to the party with a solid, if not spectacular batch of features. 

Aside from the safety tech detailed later, Included is a 10.25-inch media touchscreen, managing audio, built-in nav (with real time traffic alerts), phone connectivity and more.

Other features include, wireless phone charging (for compatible devices), a rear-view camera, automated parking assist, active cruise control (with stop-go function), climate control air, driver’s digital display, ambient interior lighting, 20-inch alloy wheels, auto LED headlights, LED DRLs, indicators and tail-lights, keyless start, rain-sensing wipers, plus heated and folding power mirrors.

But there are a few surprises. It might be an electric car, but forget power adjustment of either front seat. And despite inclusion of Apple CarPlay (BMW says Android Auto will be available later in 2020) and digital radio, the audio system only has four speakers, all in the front doors (because of the clamshell arrangement detailed later). 

Our test car featured the ‘Suite’ interior package ($2308) which brings ‘Vernasca Dark Truffle’ leather on the seats, instrument panel, doors and side trim, as well as ‘Oak dark matt’ wood trim, the steering wheel in black with a ‘Satin Silver’ contrast ring, floor mats (and general interior fabrics) in ‘Anthracite’, the roofliner in ‘Carum Spice Grey’, plus orange/white LED lighting for the door pull handles and front map pocket. A dual porthole-style glass sunroof adds another $2246, for an as-tested price of $74,454.

Things kick off the with the E model’s 135kW electric motor that also produces 290Nm of torque. That, says Mini, is enough to get it from rest to 100km/h in just under eight seconds. The motor is powered by a 38.5kWh battery living under the floor

The SE gets more battery and more power; 49.2kWh and 160kW, respectively, with 330Nm of torque on tap as well. The claimed 0-100km/h time falls almost a second to 7.1sec.

A single-speed reduction transmission is fitted and the electric motor in both models is a single one, driving the front wheels in true Mini tradition.

Of course, the other aspect of a Mini’s driving experience is its go-kart handling. To that end, the Mini EV is tuned for handling and response and features a MacPherson strut front end and a multi-link suspension arrangement at the rear. Potentially offsetting that sidestep, however, is the car’s heft which, at 1.6 tonnes, is very un-Mini.

The i3s is powered by BMW’s ‘eDrive’ hybrid synchronous electric motor, producing 135kW at 7000rpm, and 270Nm from 0-4500rpm. Yep, that’s right, maximum torque is delivered the instant you depress the right-hand pedal, and we’ll get to what that brings to the driving experience a little later.

The unit incorporates a charging and generator function for braking energy recuperation, the latter delivering up to 50kW.

Drive goes to the rear wheels via a single-speed (fixed-ratio) automatic transmission.

The battery powering the whole show is a 352-volt/120 amp-hour (Ah) Lithium-ion unit with a (gross) energy rating of 42.2kWh.

Mini claims a power consumption figure of 14kWh per 100km for the E and 14.4 for the SE. Theoretically, that should give the E a (WLPT) range of 310km and the SE a claimed maximum of 406km.

In reality, you’ll be looking for a power-point before that, because those are both maximum range projections and, in highway conditions, without the regeneration potential of suburban running, you’ll use more power per 100km travelled.

Both version of the Mini EV can use fast chargers, the E model capable of 75kW DC charging, and the SE’s bigger battery able to handle 95kW. Charging at home on an 11kW AC outlet is also possible but, obviously, takes a lot longer to reach full charge.

For DC charging, the Mini uses a CCS Type 2 charging plug.

Speaking of which, on that 75kW fast charger, the E’s battery will go from 10 to 80 per cent charged in 28 minutes, while the bigger battery in the SE will take 31 minutes, its faster charging offset by its larger battery capacity.

At 11kW AC, the Aceman E can go from discharged to fully charged in four hours, 15 minutes, while the SE will take five-and-a-half hours.

When it comes to an electric car’s energy use and projected range, there are two main things to consider - the motor’s power consumption and the battery’s capacity.

And according to BMW, the i3s’s power consumption for the combined (urban/extra-urban) cycle is 14.6–14.0kWh/100km.

Over a week, and roughly 250km of urban driving (with some brief freeway runs thrown in) we saw 19.3kWh/100km staring back at us from the on-board computer.

When BMW launched the i3 in Australia in 2014, the pure EV version came with a 60Ah battery pack delivering a claimed 130 kilometre range (a range extender model featuring the addition of a two-cylinder petrol motorcycle engine was also offered). 

In 2016 a 94Ah version arrived to boost range up to 183km, and the i3s launched in 2018, with its 120Ah battery pushing range out to BMW’s current, real-world estimate of 260km.

Then, there’s charging time, which is like asking how long is an electric piece of string.

According to BMW, for a 0–80 per cent charge from a (50 kW DC) fast-charging station, you’re looking at 45min.

From a (11kW/16A/380V) high-output home/office wall unit, that pushes out to 3.10h, and using a (3.7kW/16A/240V) low-output home/office unit stretches the wait time to 9.40h.

BMW offers the ‘WallBox plus’ charging suite as a dealer accessory priced from $1990 (not including GST or install costs).

Plug into a domestic (2.4kW/10A/240V) socket, and you’re staring down the barrel of 15.00h. But at least you can use low-cost, off-peak energy overnight, right? Nah, I don’t buy that line either.

Much is made by Mini of its tradition of go-kart-like handling. And fair enough, it’s one of the things that allows the Mini brand to justify a premium price-point. And the good news is that this version, electric driveline notwithstanding, continues that theme. Position the manually-adjustable steering column to the right spot and suddenly, you’re in a car that encourages you to enjoy the drive.

The steering is light but accurate and is actually one of the better calibrated modern, electrically-assisted set-ups we’ve sampled for a while.

The only thing it doesn’t do is give the feeling that you’re sitting right over the physical point in the car that it rotates around when it corners.

Instead, you get the impression of there being a fair bit of Mini nose jutting out in front of you, with the driver’s seat positioned well back in the cabin.

Given the extra length of the five-door layout, that’s not completely unexpected, but it’s something drivers of short-wheelbase Minis will perhaps note.

What that doesn’t affect is the way the car feels tied down pretty well, but never degenerates into a crashing, buck-board. Despite the flat cornering, there’s always some suspension travel left, it seems, and the damping is clearly spot on as it arrests wheel movement without interfering with the fun.

There’s plenty of grip, too, and if you play the Mini game and hustle it through a few corners, the Aceman quickly reveals its fun side, which is precisely the point here.

The instant urge of an electric drivetrain is also very much in evidence and flooring the throttle pedal results in an instant surge of Newton-metres. I could do without the Warner Brothers soundtrack (and I did, by turning it off) but the acceleration itself is pretty impressive without being confronting (as some EVs with their brutal delivery can feel).

The only other thing we’d comment on is a level of tyre and road noise that is far from best in class. Okay, so a bit of tyre roar is okay, and it’s only audible at all because silence from traditional mechanical sources is such an EV thing.

It might not look like a conventional sports car, but the BMW i3s certainly accelerates like one, with a claimed 0-100km/h time of 6.9sec. The i3s is a smile-inducing hoot to drive.

Every one of this little hatch’s 270 newton metres of torque is available from the minute you hit the accelerator pedal, and remain in service until 4500rpm, at which point torque delivery drops off a cliff.

But peak power steps in at exactly 7000rpm, so if you’re determined to make that overtaking move you won’t be left in the lurch. In fact, BMW says it only takes the i3s 4.3 seconds to surge from 80km/h to 120km/h.

However, the i3’s forte is 100 per cent the city, rather than the open road. Its ‘point and squirt’ ability making it the perfect partner for the cut and thrust of the urban jungle.

The i3s features an upgraded ‘Sports Suspension’ incorporating firmer dampers, re-tuned springs and revised anti-roll bars. It’s also lowered 10mm, the track is widened (+21mm front / +2.0mm rear) and the wheels go plus one inch to 20-inch alloys.

The standard i3 (no longer offered in Australia) rolls on 19-inch rims shod with 155/70 rubber all around. And while the i3s’s 175/55 front and 190/50 rear tyres are still exceptionally narrow, from the side the low-profile Bridgestone Ecopias look like fan belts wrapped around pulleys rather than tyres around wheels..

No surprise then that ride comfort isn’t exactly cushy, and in signing on for the i3s experience you’ll need to be ready for more than occasional bumps and thumps.

But the pay-off is super-sharp dynamics, Suspension is by alloy struts at the front, and a five-link alloy set-up at the rear..The steering responds to inputs quickly yet smoothly, and with 48/52 front to rear weight distribution, the car always feels balanced, eager, and taut.

And if you really want to dial things up the ‘driving experience control’ allows a switch to Sport mode for a further tweak of the suspension, steering, and traction control set-ups.

A tight 10.3m turning circle makes for easy parking and stress-free U-turns. But if things get too tight, rapid three-point turns are assisted by the gear shift controller bring mounted on a chunky stalk on the right-hand side of the steering column. Too easy.   

Braking is by vented discs front and rear, but they’re tiny. That’s because the ‘Brake Energy Regeneration’ system does most of the work. 

Effectively turning the motor into a generator, the system not only slows the car dramatically but feeds energy to the battery in the process. It takes a while to get used to the sensation, but soon becomes a fun, and surprisingly easy game to use the brake pedal as little as possible… often not at all, for long periods.

The i3 scored a maximum five ANCAP stars when it was assessed at the time of its local launch in 2014, and the standard safety spec has been boosted since then.

Active tech includes ‘the usual suspects’ such as ABS, EBD, and ESC, as well as city-speed AEB (with 'Forward Collision Warning', and  'Traffic Sign Recognition'). reversing collision avoidance, a reversing camera, and tyre pressure monitoring.

If all that doesn’t prevent an impact, passive safety tech includes, dual front, side chest and side curtain airbags.

There are also top-thether points and ISOFIX anchors to secure child seats/baby capsules in both rear seating positions, as well as a first aid kit and warning triangle..

The Mini factory warranty was extended a couple of years ago to five years/unlimited kilometres. That’s an improvement on the three years the brand previously covered, but it’s still well short of the seven, eight and even 10 years of some competitors. In the fully electric Aceman’s case, there’s also eight years/160,000km worth of cover for the high-voltage battery. There’s also five years of roadside assistance thrown in.

There are no set service intervals for the Aceman, Mini instead preferring to use the concept of condition based servicing which involves the car telling you when its ready for maintenance. There’s capped price servicing available which costs $1371 for the first four years.

Beyond that, running costs will depend heavily on where and how your charge the car. Charging at home form a solar array will be the cheapest, while using commercial fast-chargers will inevitably ratchet up your running costs.

BMW offers a three year/unlimited km warranty, which is off the pace given the majority of mainstream brands have stepped up to five-year cover, with some at seven. And the pressure is on with Mercedes-Benz recently announcing its shift to five years/unlimited km.

That said, the BMW's body is warranted against rust (perforation) for 12 years/unlimited km, and roadside assistance is provided free-of-charge for three years/unlimited km.

Maintenance is 'condition based' with sensors and on-board algorithms (mileage, time since last service, driving style) determining whether an annual vehicle inspection is required.

The 'BMW Service Inclusive' package, offering a single, one-off advance payment to cover selected service and maintenance costs, is available in two levels - 'Basic' ($850) or 'Plus' (dealer quote)
