It seems like cat is out of the bag. For the past few weeks we’ve been hearing rumors around a possible “street version” of the BMW M3 GT4. The first prototype was spotted at Nurburgring last month and shortly after, the speculations began.

We’ve been sitting on some information for weeks now since we promised our sources that we won’t reveal anything until its official launch, but several online forums are reporting new information today. As we heard as well, the “CSL-like” M3 will NOT carry the CSL name, but rather use GT4 or simply GT naming convention. The car will be revealed sometimes this month.

In the mean time, here are some new information, courtesy of M3post:

* It won’t be called M3 CSL.
* Instead, BMW will either call it “M3 GT4 Street” or “M3 GT”.

Engine | Drivetrain

* Naturally aspirated engine with an increased displacement of 4,400 cc (based on the S65).
* At least 450 hp, likely more. (445 HP)

* Weight reduction of 100 kg (220 lbs) compared to E92 M3, maybe even more. (due to the removal of the rear seat and the switch to lighter RECARO front race seats)
