We have a world exclusive today with a look at the technical details of the first ever electric MINI Aceman. We’ve known the Aceman will be smaller than the new Countryman but until today we didn’t fully understand what that meant. And the numbers are interesting to say the least. Especially in how they compare to smaller MINIs of the past.

One of the headlining data points of any MINI is length. Aceman measures in at be 4079mm / 161in in length which is (not surprisingly) quite a bit smaller than the 4444mm / 175in U25 Countryman. However what’s really interesting is comparing this new MINI crossover with the original 2010 R60 Countryman. The R60 was 4119mm / 162.2in making that original Countryman actually larger than the new Aceman. Going deeper we see that trend playout elsewhere; R60 shoulder width is 1341mm / 52.8in which is smaller than the 1370mm in the Aceman. Not surprisingly the same is true for front legroom. There the R60 is 1025mm / 40.4in. while the smaller Aceman looks for comfortable with with 1045 mm / 41.1in of room for front passengers.

You get the idea. The Aceman has a small footprint but is magically larger inside than the original Countryman. This is a result of MINI using a bespoke electric platform and being able to rethink much of the interior design.

The Aceman is slotted below the new MINI Countryman and effectively replaces the wagon-like Clubman. However the Aceman is electric only and will share much of the technology we’ve already in the J01 MINI Cooper EV. The new J05 Aceman will be available initially in E and ES variants with the JCW version to follow shortly after launch. The E will have an output of 135 kW/184 hp while the SE will offer 160 kW/218 hp and torque of 330 Nm. A JCW model will arrive shortly after launch and will concise with the launch of the J01 JCW MINI Cooper as well.

Aceman Specifications vs the U25 Countryman

Now let’s take a look at the full specs and how that compares to the new electric Countryman SE.

Weight is interesting here as we see just how MINI has mitigated the heavy battery. While a 3,600 lbs car can’t be considered light, it is for a four door electric crossover. The other number that jumps out is just how close the wheelbase is to the Countryman. This shows MINI has pushed the wheels to the corners as much as possible.

Next we’ll take a look at the performance and how it compares to the J01. As you can see MINI has carried one the drivetrain completely including battery size. While we don’t have range figures yet, it’s safe to say they will be lower than the J01 due to the increase in weight of the Aceman.

J05 MINI Aceman Release Info

The MINI Aceman will initially be built in China by a joint venture with Great Wall Motors. We believe those vehicles will be sold in Asia and Europe exclusively. Then in 2027 MINI will move some of that production to Oxford along with the J01 MINI Cooper EV. These cars coming out of the UK will serve Europe and likely the North American markets and will allow MINI to avoid tariffs as it begins US imports in the 2027 calendar year. While it’s too early have a full picture of cost, we’d expect finally pricing to be 10-15% cheaper than the U25 Countryman EV.

The Aceman is just one part of the 4th generation MINI family but a key one in its strategy to go all electric. Here’s a full view of the fourth generation MINIs and where it slots in.
