Oh look, a carbonfibre bonnet up front, new spoiler at the back.

The M3 with optional Competition Package might be a bit too soft for you, but what are you to do? Thankfully BMW is giving its hot small saloon the CS treatment along the same lines as the M4.

Caught at a petrol station, the prototype had the carbonfibre vented bonnet and rear spoiler of the M4 coupe.

Not only that, but the prototype was wearing the exact same 19-inch front and 20-inch rear wheels finished in Orbit Grey. The reason for the camouflage on the front bumper was to disguise the new front splitter made from carbonfibre reinforced plastic. The CFRP weight loss programme on the M4 CS shaved off around 32kg, so we can expect the M3 to benefit to a similar degree.

While the taillights appear to be the standard ones installed on the facelifted M3, we wouldn't be too surprised if BMW will decide to adopt an OLED setup as seen on the M4 CS (and the more exclusive M4 GTS). Aerodynamic tweaks, upgraded suspension and a beefier version of the straight-six 3-litre turbocharged engine are in the offing as well.

The engine is expected to deliver 460bhp and 442lb ft channeled to the rear wheels through a seven-speed dual-clutch automatic transmission. Performance numbers will likely mirror those of the M4 CS, which takes 3.9 seconds to get to 62 mph (and tops out at an electronically restricted 174mph.

The M3 CS will likely debut next year as a limited edition model taking into account the M4 CS was capped at 3,000. Naturally, it’s going to be significantly more expensive than an M3 Competition Package, but that shouldn’t be much of a problem as we have a feeling all units planned for production will be sold right away.
