As with the J01 MINI Cooper, some markets will be offering JCW (or sport) trim that will mimic the look of the full JCW model coming later this year. In other words this is our best look yet at how that highly anticipated petrol MINI Cooper JCW will look when it debuts 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. There’s also functional brake ducts as we’ve seen on the F56.

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.

2025 MINI Cooper JCW – Power and Performance

The headline is that 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.

Despite this the F66 will have a slightly revised B48 engine under the hood – more specifically the B48A20O2. So what is this revision actually getting would be owners? Torque which will increase from 236 to 258 ft lbs giving the car a touch more grunt. And it peaks lower in the rev range as well. 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.

Why are we not seeing an improvement when the Cooper and Cooper S are getting modest power upgrades? Or the Countryman which gets even bigger power hikes? We don’t have great answers other than this lack of a JCW upgrade 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.

A Few Surprising Changes in Size

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. For instance the F56 JCW has a length of 3863mm vs 3876mm for the new F66 JCW. Why the change? From our information that’s due to the new bumper design (driven by either aero of new safety standards) might be the culprit.

The height change is also interesting. The F56 Cooper JCW is 1414mm vs the F66 Cooper JCW which is higher at 1432mm. This is connected to larger standard tires with an increase circumference.

It’s the width that is the most interesting to us. The F56 Cooper has a width of 1727 mm vs the F66 which is wider at 1744mm (both without mirrors). That 17mm 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. Which leads to…

JCW Wheels That Finally Look Normal

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 To Feature 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.

The Cooper JCW – Once Again Available in Two Flavors

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.

The JCW Manual Transmission Is Gone

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. In fact since we exclusively reported the news early this year, the MINI USA manual take-rate has gone up to over 50%.

It’s devastating move for a lot of MINI’s biggest fans as it’s a huge part of the brand’s history and slots well into the MINI’s core philosophy of creating cars that are engaging the drive. 

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. 

Corresponding with the move away from manuals is a completely new gear lever design that mirrors what we’ve seen on the electric J01 and U25 MINI Countryman. What will remain are revised paddle shifters which will be standard on all JCW models.

However in markets like US, where CO2 targets don’t have the same impact, why not continue to offer it? That’s likely down to the business case. Offering it one country means that the volumes go down dramatically which means MINI is spending more per unit and MINI would lose a chance to simplify the production process just has it’s about to get more complex with new models.

In its place will be a revised 7 speed dual clutch (DCT) with slightly more aggressive software for more aggressive programing which should decrease shift times. The revised dual clutch transmission is just like the one offered in current Cooper and Cooper S models combining two partial transmissions in a single housing. The core element of the system consists of two oil-cooled wet clutches: one of these is responsible for the even transmission ratios (2, 4, 6) while the other is for the uneven ratios (1, 3, 5, 7) and reverse. During travel, one of the two clutches is open and the other is closed. They interact when the driver shifts up or down: opening one clutch activates closure of the second at the same time.

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.
