Our spy photographers recently spotted the BMW M4 out testing wearing some camouflage on the front and rear bumpers.

This clearly indicates that the car is ready for a facelift. The particular example spotted here is a BMW M4 Convertible, but the M4 Coupe and M3 Sedan will likely receive the same updates. The M3 and M4 first arrived for the 2021 model year, with the drop-top arriving later as a 2022 model. BMW typically updates its cars with a lifecycle impulse (LCI) every four years, so the timing makes sense for the 2025 model year.

Most of the changes will be limited to the bumpers based on where the damage is placed. The grille up front appears to remain untouched, much to the chagrin of enthusiasts who hate the huge nostril look, but the headlights show off some new graphics.

At the back, the taillights also tease a new pattern that seems to be inspired by the M4 CSL, a hardcore special edition with more power than a standard M4 and a significant weight reduction. Every other exterior detail appears to be the same on this test mule, though we suspect the car could gain some new wheel patterns.

Inside, the M4 should be updated with the latest iDrive version. This new software is set to debut in the next-generation 5 Series and includes a more intuitive layout than what's currently available on iDrive 8. Our spy photographers couldn't get a closer look at the interior to see if there were any other noteworthy changes.

Since this is only an LCI, we don't expect to see any changes under the hood. This means the 3.0-liter twin-turbocharged S58 inline-six should carry over with 473 horsepower or 503 hp in Competition guise. The former is only available with a six-speed manual transmission sending power out to the rear wheels, while the latter can only be paired to an eight-speed automatic with RWD or optional xDrive all-wheel-drive. The M4 Convertible is only available with xDrive.

We expect BMW to introduce a new performance variant above the Competition but below the CSL, called the M4 CS. This model should borrow the uprated engine from the M3 CS, which produces 543 hp. The CS will offer the same power as the CSL but without the extreme diet and suspension changes that make it too uncomfortable to use as a daily driver.
