Exclusive: MINI Aceman Dimensions & How it Compares to the Countryman

DimON · January 31

As you’ve probably gathered the new four door MINI Aceman EV is smaller than the Countryman. But just how small and where does it fit into the line-up exactly? Today we have an exclusive look at the dimensions of the Aceman and how it stacks up to the all new Countryman as well as the previous generations. Some of the figures may surprise you.

Small Where it Matters & Big Where it Counts

The Aceman is a small crossover that is effectively replacing the Clubman in the MINI line-up. But in reality it doesn’t replacement the Clubman at all. Rather it fills the void left when the Countryman grew in size from the original R60 model to the more recent F60 model.

Case in point, the Aceman’s length. In photos it’s hard to tell because the tall belt-line and large wheels. But the length is actually bigger than you might think. The MINI Aceman measures in at be 4079mm / 161 in in length. That’s a full 14″ shorter than the 4444mm / 175 in new U25 Countryman.

Models	J05 Aceman	R60 Countryman (’10-’16)	F60 Countryman (’17-’23)	U25 Countryman (’24-’32)
Length	4079 mm / 161 in	4097 mm / 161.3 in	4298 mm / 169.2 in	4429 mm / 174.37 in
Height	1514 mm / 59.6 in	1562 mm / 61.5 in	1557 mm / 61.3 in	1613 mm / 63.5 in
Wheelbase	2526 mm / 99.44 in	2596 mm / 102.2 in	2670 mm / 105.1 in	2670 mm / 105.11 in

Things get really interesting is when you compare the Aceman to the original 2010 R60 Countryman. The R60 was 4119mm / 162.2in making that original Countryman actually larger than the new Aceman. When you look and height and wheelbase the Aceman is also fractionally smaller. However while the R60 has a larger footprint, things look a bit different inside.

For instance the R60 Countryman’s shoulder width is 1341mm / 52.8in. Aceman actually has over an inch more room with a width of 1370mm / 53.9. Not surprisingly the same is true for front legroom. There the R60 is 1025mm / 40.4in while the smaller Aceman looks slightly more comfortable for taller drivers and passengers with 1045 mm / 41.1in of room in the front.

Not unlike the original classic Mini, the Aceman is great at being small on the outside while being surprisingly rooms inside. This is a result of clever packaging thanks to MINI using a bespoke electric platform.

Aceman Specifications vs the Electric U25 Countryman SE

Now let’s take a look at the full specs and how that compares to the new electric Countryman SE. Here you’ll see some clear distinctions that MINI has made to separate these two products. The most obvious (beyond size) is power and number of wheels drive. Yes, the Aceman is a solely front wheel drive vehicle.

Models	J05 Aceman E	J05 Aceman SE	U25 MINI Countryman SE
Power	184 hp	218 hp	313 hp
Torque	214 lb-ft	243 lb-ft	365 lb-ft
Transmission	1 speed	1 speed	1 speed
Wheels Driven	Front Wheel Drive	Front Wheel Drive	All Wheel Drive
0-60 mph	TBA	TBA	TBA
Length (mm/inches)	4079 mm / 161 in	4079 mm / 161 in	4444 mm / 175 in
Width w/o Mirros (mm/inches)	1754 mm / 69 in	1754 mm / 69 in	1843 mm / 73 in
Height (mm)	1514 mm / 59.6 in	1514 mm / 59.6 in	1661 mm / 65 in
Wheelbase (mm)	2606 mm / 102.6 in	2606 mm / 102.6 in	2670 mm mm / 81 in
Curb weight (kg/lbs)	1645 kg / 3,627 lbs	1710 kg / 3,770 lbs	1735 kg / 3,825 lbs
Luggage capacity (seats up/seats down	300 / 1005 liters	300 / 1005 liters	450 / 1450 L

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.

	2025 J01 MINI Cooper E	2025 J01 MINI Cooper SE	2026 J05 MINI Aceman E	2026 J05 MINI Aceman SE
Horsepower	184 hp	218 hp	184 hp	218 hp
Range (WLTP)	200 miles	250 miles	TBA	TBA
Battery Size	40kWh	54kWh	54kWh*	32.6 kWh

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.
