2025 MINI Cooper F66 vs F56: The Full Breakdown After 12 Months Behind the Wheel

[DimON]

At first glance, it’s easy to assume the new F66 MINI Cooper is just a lightly updated F56. But look closer, and the story gets far more interesting. Despite sharing the same basic chassis, the F66 is shorter yet more spacious, packed with more tech, and surprisingly—offers fewer choices for buyers. Over the past year, we’ve driven every variant across two continents to find out what’s really changed, what’s improved, and where MINI may have taken a step back. Here’s what we’ve learned.

The new petrol-powered F66 MINI Cooper might seem like a mild refresh of the outgoing F56. It isn’t. Despite riding on the same chassis, this is a full-scale re-engineering—what MINI insiders have dubbed “a rethink of the refresh.” And after a year hands-on with every variety possible, we can confirm: this isn’t just a facelift—it’s MINI making a calculated, subtle step forward.

Rewriting the Dimensions

Let’s start with the exterior—where almost every dimension has subtly, but significantly, changed. The front and rear overhangs have been trimmed slightly. But it’s the increase in width that’s most notable: from 75.9 inches in the F56 to 77.6 inches in the F66. That 1.7-inch gain isn’t just for visual drama—it’s functional.

The wider track (front and rear) and increased wheel width (from 205mm to 215mm on the Cooper S) are thanks to small but meaningful mechanical changes beneath the skin. In our driving experiences it gives the F66 slightly more eager turn-in than before. It’s also allows for a deeper, more concave wheel designs—a long-requested change among enthusiasts, especially those who found the JCW’s previous flat-faced wheels underwhelming.

And yes, the boot has grown slightly too. Up .2ft thanks to re-contoured inner panels and minor packaging tweaks—another signal of how extensive this redesign actually is.

Carryover? Not Much

From a design standpoint, nearly every exterior panel is new. The roof, doors, and glass are all that remain from the F56. Everything else—the sculpted bonnet, the simplified front fascia, the more upright stance—is new. One particularly subtle but impactful change is the revised headlight angle. Combined with a taller bonnet and squared-off proportions, the F66 feels more upright than before.

Fighting the Bloat: The Weight Story

Critics love to claim MINIs keep getting fatter. But the data paints a more nuanced picture. The R50 Cooper (manual) weighed in at 2,535 lbs, which dropped to 2,513 lbs in the R56. The F56 did grow (2,701 lbs manual / 2,756 lbs DCT), but not by SUV-like margins.

Now comes the F66 Cooper—offered only with a 7-speed DCT in the US—with a curb weight of 2,778 lbs. That’s just a 22-lb increase over the outgoing F56 DCT, despite meeting stricter crash regulations, packing in more tech, and adding hardware to support Level 2 autonomy in the future. In today’s context, that’s almost a miracle.

Note that these are all DIN certified weights. Markets such North America measure curb weights differently and are often higher due to more standard equipment.

The Interior Revolution

Where the exterior is evolutionary, the interior is nothing short of revolutionary. MINI has lifted the entire dashboard concept from the all-electric J01 and planted it into the F66—bringing with it the brand’s most advanced infotainment ever.

At the center of it all is the new 9.4” circular OLED display running MINI Operating System 9, a UI experience developed in-house and based on Android Open Source Project (AOSP). It’s bold, it’s fast, and it’s unapologetically different. Physical buttons are minimal, but key toggles remain for essentials—volume, drive modes, defrost, and start/stop.

We’ve spent hours with this system across multiple models, and while the learning curve exists, it flattens quickly. Features like the augmented reality navigation—projecting turn-by-turn graphics directly onto live video—are a revelation, particularly in urban environments. It’s also quick: we found it on par with Google Maps in responsiveness and clarity.

More importantly, this is MINI embracing a new digital-first identity while still holding on to its analog charm in the right places. The quirky animations, customizable soundscapes, and themed drive modes (Core, Go-Kart, Green) all add layers of personality that make the F66 feel alive—something few cars in this class manage anymore. Yes they go a bit too far at times but thankfully they can (mostly) be turned off.

Verdict: The Best of Both Worlds?

The F66 was’t an easy product to pull-off for MINI. It’s not just an F56 with a bigger screen and a wider stance. It’s a deeper, more thoughtful revision that honors MINI’s design language and dynamic focus while future-proofing the car for evolving consumer and regulatory demands.

Is it perfect? No. We desperately miss the manual and would love to see more color and trim options. But what we can say for certain: MINI has taken the bones of the F56 and built something smarter, sharper, and surprisingly soulful.
