Exclusive Look: The 2025 F66 MINI Cooper JCW – The Last Internal Combustion JCW

[DimON]

MINI isn’t going all electric. At least not yet. There’s one more petrol powered MINI Cooper coming and with it one more Cooper JCW. In this exclusive look we have final details on almost every aspect of the new Cooper JCW including power, performance and even styling details that might even shock you.

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.

Shortly after the F66 will be the F67 JCW Convertible

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? For one the Countryman’s B48 engines contain a mild hybrid power unit while the Cooper engines will not due to packaging restrictions. Otherwise 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.

Yes, that is a single exhaust pipe you see

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.

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

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 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 hatch and the 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 F66 gear selector moves from the console to the dash in the form of a discrete toggle switch.

The JCW Manual Transmission Is Dead

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.

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

2025 MINI Cooper JCW Wheel Options

Similar to the F56 we’ll see several JCW option ranging from 17” to 18” wheels. However the design of those wheels will change. Tire sizes however will remain consistent with the F56.

F66 ICE MINI Cooper	F66 ICE MINI Cooper S	F66 JCW
16” 4 Square Spoke	17” U-Spoke grey	17” John Cooper Works Sprint Spoke black
17” U-Spoke vibrant silver	17” U-Spoke vibrant silver	18” John Cooper Works Lap Spoke 2-tone
17” U-Spoke grey	17” Parallel Spoke 2-tone	18″ John Cooper Works Lap Spoke 2-tone w/Sport tires
17” Parallel Spoke 2-tone	18” Night Flash Spoke 2-tone
18” Slide Spoke 2-tone	18” Slide Spoke 2-tone

The 2024 F56 Cooper SE and the 2025 J01 Cooper SE. The F66 will adopt the styling of the J01 inside and out.

Why is MINI Refreshing the F56 rather than Replacing it?

If you’ve been following MotoringFile you’ll know that MINI is splitting its core model – the Cooper – into two distinct products. That means we’ll see two next generation MINI Coopers (hatches) built on opposite ends of the planet on two different platforms; one a EV (J01) and one ICE powered (F66). This move will allow MINI to offer innovative electric offerings while still selling to the traditional ICE market for as long as possible. 

The J01 JCW trim. While not a fully JCW production, it gives us a clue as to how the J01 and F66 JCW model will look.

The F66 will see styling changes that mirror the J01 and huge tech improvements inside the cabin. But mechanically it will be mostly the same car with just the Cooper S getting a noticeable engine upgrade (more on that soon).

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.
