Last year, CarBuzz spotted a trademark for a new Mini model called the Aceman, not to be confused with the unloved and discontinued Paceman.

A few months ago, the Aceman Concept made its debut, previewing an upcoming electric SUV. Not long after the reveal, a prototype Aceman has already been spotted undergoing testing in preparation for production.

The test mule is heavily camouflaged, but we can still spot some details from the concept that will make it onto the final version. If you liked the looks of the concept, this is good news. The first two spy shots show a higher-trim model with nicer wheels, while the photos taken on the transporter likely show an entry-level trim.

It may be tough to get a good sense of scale while the vehicle is on the back of a truck, but the Aceman will likely slot below the Mini Countryman but above the Clubman in size.

The Aceman will ride on the same electric platform as the upcoming Cooper EV being developed with Great Wall Motors in China.

As previewed by the concept, the Aceman will be smaller than the Countryman in length but pack more space inside, thanks to its lack of a gasoline engine or transmission. The next-generation Countryman is set to grow in size, likely to avoid overlap with the Aceman.

These spy shots tell us that the production headlights and taillights will closely resemble the concept. This test mule does not appear to have the concept's light bar around the grille, but perhaps that styling element is hidden by the camo.

Mini will adopt the same recessed door handles also used by parent company BMW, a styling element previewed by the concept.

The base wheels feature a split four-spoke design, while the upper model rides on larger wheels with a unique pattern. After Mini teamed up with a gaming convention to promote the Aceman Concept, we wonder if the production model will come in a Pikachu special edition.

Mini never shared any details about range or power with the concept, so we know very little about the powertrain. The company's current EV, the Mini Cooper Electric, develops 181 horsepower and 199 lb-ft of torque but only travels 110 miles on a charge.

For the Aceman to succeed in the US market, those performance figures need to improve, as does the range. Expect to see a production reveal sometime in 2024.
