The F66 MINI Cooper S has debuted and is now in production. But what about the JCW version? We’ve got exclusive details on MINI’s top spec Cooper on everything from power, torque to design details and release dates. The manual transmission might be gone, but this new JCW looks like the best yet.

2025 MINI Cooper JCW: Design

Starting with styling we can immediately get a good idea of how the new F66 JCW will look but simply looking at the JCW Trim offered in Europe. Also known as Sport Trim in the UK, this takes the JCW bodykit and applies it to any MINI in those markets. According to sources there will be almost no differences between the way these cars with the JCW Trim look and the full JCW coming later this year.

Looking at these renders we can clearly see the J01’s JCW Trim design aesthetic was followed closely. The front bumper however has real ducts due to the need to cool the JCW B48 engine and we’re told the brake ducts also remain.

In fact the JCW front bumper is quite close to what we’ve seen previously on the F56 as you can see below. Elsewhere you can clearly see MINI has moved to gloss black side skirts on the JCW along with gloss black fender flares. This follows the trends towards gloss black we’ve seen elsewhere. Time to get your polishing cloths out.

2025 MINI Cooper JCW: Performance

In what will be seen as a major disappointment, the 2025 MINI Cooper JCW will not see an increase in horsepower. Unlike the Cooper or the Cooper S, MINI is holding the line on power output and instead bringing some upgrades elsewhere.

Shortly after the F66 will be the F67 JCW Convertible

But that doesn’t mean there aren’t any performance upgrades. The F66 JCW will have a slightly revised B48 engine under the hood – more specifically the B48A20O2.

The big performance update will be torque which increases from 236 to 258 ft lbs giving the car a bit more grunt. Perhaps just important, it peaks lower in the rev range as. Previously in the F56 JCW torque maxed-out at 1,450. The B48A20O2 sees this change to 1,250 rpm meaning maximum power is even more immediate. These are small but subtle differences that point to a slightly quicker or more responsive B48 engine.

Why are we not seeing a bigger improvement when the Cooper and Cooper S are getting noticeable power upgrades? Or the U25 Countryman which gets even bigger power hikes (especially in the US market)? We don’t have great answers. It could be related to emissions and the reality that, updating this version of the B48 isn’t high on BMW’s priority list. It also leaves room for MINI to eventually tweak software and hardware for a light refresh in a few years. And we know the DCT transmission can handle more torque so there appears to be no component related reason holding MINI back.

While this isn’t the JCW, the new F66 Cooper S will be nearly identical

2025 MINI Cooper JCW: Size Changes

While the F66 JCW is based on the F56 JCW, the dimensions aren’t identical likely due to styling and even a few engineering changes. As you can see above the new car is actually slightly short yet taller. Why the raise in height? This is connected to larger standard tires with an increase circumference.

However it’s the width that is the most interesting to us. The F56 Cooper has a width of 75.9″ mm vs the F66 which is wider at 77.6 (both without mirrors). That 1.7″ difference may not sound like much but BMW and MINI don’t typically increase the width of a car solely because of aesthetics. This is due to the wheel and tire size increasing. Tires are now 10 mm wider at 215 and the wheels have been sized up accordingly. Additionally MINI has tweaked the underlying mount points slightly as well.

The new F66 MINI Cooper JCW is a mix of the new and familiar

2025 MINI Cooper JCW: Wheel Updates

The F56 JCW is a great car with an engineering decision that has created an awkward styling issue. The because of the size of the front brakes and the wheel offset, all JCW wheels bow outward creating an unusual convex shape that looks very different than typical concave performance wheels. As you can see in these photos as MINI has clearly changed the geometry of the wheels which seems to have eliminated that issue entirely. MINI will offer the 17” JCW Sprint Spoke as standard (which we see above) and the 18” John Cooper Works Lap Spoke 2-tone as an option (seen on the F67 convertible below).

The current F56 Cooper S Exhaust design shows that the “dual exhaust” is nothing more than two small pipes from a single exhaust.

2025 MINI Cooper JCW – Single Pipe Exhaust

In another surprising move MINI is moving from a two pipe single exhaust to a larger single pipe exhaust. In the exclusive image below you can see a single exhaust pipe (with a stainless steel sleeve), the transversely mounted exhaust and even the aluminum shield underneath it. Look even closer and you’ll see the production version of the single LED reverse light just above the exhaust tip which (one could imagine) would look somewhat integrated with the cutout of the pipe.

Why a single exhaust pipe? Let’s start with the exhaust itself. One thing that most don’t know is that the MINI Cooper S and JCW have had a single muffler system since the R56. The fact that two outlets came out the back has primarily been for aesthetics.

In this exclusive zoomed in photo you can see a central exhaust and single pipe that looks to be in nearly final production form.

In fact there have been more than a few MINI race cars over the years that have gone with the exhaust single pipe design. Why? When asked they consistently have told us it’s both more power efficient and lighter. So in other words exactly what you want in both race cars and modern performance cars.

Why wouldn’t MINI have always had a single exhaust? It comes down to marketing and the very simple concept; two exhaust pipes means more power than one in the eyes of the car buying public. In fact you’ll see this on display later this year when the quad-exhaust JCW Countryman debuts.

2025 MINI Cooper Convertible JCW

As before MINI will be offering the JCW model in the iconic three door F66 hatch and the F67 convertible. Once again MINI will not be offering its highest performance model in the five door configuration. Why? Product planners apparently made that call many years ago in the F56 generation and due to tight development budgets due to having to offer both electric and ICE models, they’re sticking to it.

2025 MINI Cooper JCW: One Transmission

For those reading MotoringFile this likely won’t be a total surprise as we’ve reported on this several times over the last 9 months. But it’s still a shocking development given the popularity of the option – especially last year when we saw over a 50% take rate in the US.

Why would MINI eliminate manuals despite the fact that the F66 is mechanically identical to the F56 and could easily carry over the current Getrag 6 speed? It’s likely about simplifying drivetrains components and cutting costs within manufacturing. And for Europe (where CO2 targets are much more stringent) the manual is slightly dirtier. 

Replacing the manual is a revised 7 speed dual clutch transmission that promises faster shift times than before and a more responsive manual control via the standard steeling wheel mounted paddles. Along with this will be an entirely new gear lever design that mirrors what we’ve seen on the electric J01 and U25 MINI Countryman.

Chassis and Brake Updates

This is where the F66 MINI Cooper JCW is a straight evolution from the F56 version. This starts with the braking system which will be carried over. That means we’ll see a 4-piston fixed caliper upfront with internally ventilated, drilled brake disk up front (335x30mm). In the back (where there’s less weight to worry about) MINI will continue with a single piston floating caliper and a disk that’s 259x10mm. All four calipers will be finished in the traditional Chili Red.

The chassis and suspension will see subtle improvements with MINI further refining its adaptive suspension design. While we don’t yet have details we’re told this focuses on improving ride quality while not forgoing any performance.

2025 MINI Cooper JCW Launch Timing and End of Production

Produced in Oxford, the F66 will take over as the F56 ends production in February of 2024. That means we’ll see the first F66 MINI Coopers roll off the line next March as the plant begins its pivots into a new generation of MINIs. We expect the F66 MINI Cooper JCW will go into production beginning in March of 2024.
