Exclusive: F66 2025 MINI Cooper Technical Details Revealed

The F66 2025 MINI Cooper will be the last ever internal combustion car from the brand. And today we finally have finally have a look at some key technical data. While the F66 might be heavily based on the F56, there are some surprises in the dimensions and even weight as figures. Let’s dig in to the details.

Despite MINI’s talk of going electric with the all new J01 Cooper, it’s releasing one last generation of ICE (internal combustion engine) MINI Coopers early next year. Code-named the F66, this last ICE MINI Cooper is a heavily revised F56 complete with an almost identical exterior design complete with new trim, lights and wheels among other things. Inside the F66 will take the interior from the J01 complete with circular screen, new materials and a very different layout.

Power Increases On Most Models

Perhaps the biggest headline figures we’ve known about for some time thanks to our early reporting. The standard Cooper goes from 134 to 155 hp while the Cooper S goes from 189 to 200. The JCW (as report) will unfortunately not see a bump in power but does see a healthy increase in torque. You can read much more detail on the drivetrain improvements in our recent article on MINI’s revised engine line-up.

A Few Surprising Changes in Size

While the F66 is based on the F56, the dimensions aren’t identical likely due to styling and even an few engineering changes. For instance the F56 has a length of 3863mm vs 3876mm for the new F66. Why the change? It’s still unclear but we’d assume the new front or rear bumper design (driven by either aero of new safety standards) might be the culprit.

The height change is also interesting. The F56 is 1414mm vs the F66 which is higher at 1432mm. That might be due to MINI increasing the standard wheel size of the Cooper from 15″ to 16″ wheels while increasing the tire size slightly as well.

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. It’s very likely the result of some engineering changes that might include things like a revised suspension, wider wheels and tires or even updated plastic fender arches. Or it could be as simple as a revised front bumper that’s a touch wider than before.

A Subtle Weight Change

One of the biggest critiques of modern MINI is that they appear to be getting larger and heavier with every generation. That’s actually not historically true. The R50 (manual) had a DIN weight of 2,535 lbs which then decreased to 2,513 with the R56 Cooper (manual). That weight finally did go up with the noticeably larger F56 but again, not as much as people assumed. The F56’s DIN weight is 2,701 lbs in manual form and 2,756 with the DCT. Given that the F66 will only be available with the DCT, let’s compare those two numbers.

The F56 Cooper DCT weights in at 2,756 lbs. The new F66 Cooper DCT has a curb weight of 2,778 lbs, a 22 lbs difference. Given the added emissions and safety additions (and not to mention the new tech), a 22 lbs increase doesn’t seem all that much in the gran scheme of things.

While that’s our quick take, have a look yourself.

The F66 2025 MINI Cooper Model Range

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 it’s pivots into a new generation of MINIs.

As you can see above the changeover will happen in three phases. The first is the iconic two door Cooper which should be available at launch in Cooper and Cooper S models. We believe MINI will formally begin production of the JCW version of the F66 a little alter in July but that’s yet to be confirmed. There’s still a chance we could see that actually happen in March as well.

Next will be the five door F65 MINI Cooper launch in both Cooper and Cooper S models. Finally the brand will launch its last ever ICE car, the F67 convertible in Cooper and Cooper S models. We believe the JCW F67 will either launch simultaneously or follow in March of 2025.

Official Release and Ordering Dates

Because MINI is aggressively becoming an electric brand, it’s appears to be much more focused on the launch of the J01 and electric Countryman for the time being. That leaves the F66 in an interesting spot given that it will likely be a volume seller in markets such as the US. While we don’t have concrete info on official release or ordering dates yet, the fact that our sources aren’t telling us anything yet would likely indicate that MINI will wait until closer to the the start of production in March 2024 to formally launch the car.
