The BMW M4 GTS is the pinnacle of the M3/M4 lineup and one of the most track-focused BMWs ever built by the Bavarians. But now, BMW might have another M4 GTS update in works, one that could bring the GTS to the next track level.
A revised M4 GTS was spied in Germany featuring a pair of front canards, huge intakes side skirts, a larger diffuser, a bigger rear wing and a trunklid spoiler. On the side, we see Porsche GT3 RS-aping arch vents and gaping cutouts ahead of the doors. These aero upgrades are definitely functional and have probably increased the coupe’s downforce levels by a considerable amount.
The spy photos can be seen here.
It remains to be seen if new power upgrades are placed under the hood as well. For now, the M4 GTS uses a 493 hp version of BMW’s 3.0-liter twin-turbocharged inline-six engine with water injection system. It also has 442 pound-feet (600 Newton-meters) of torque and weighs in at 1,510 kilograms (3,329 pounds).
The current M4 GTS clocked a 7:28 at the end of 2015 but with a bit more power from the water injected, turbocharged straight-six, plus the extra aero, that number could be beat.
It’s not clear what BMW has planned for this extra hardcore M4 GTS, but it could serve as a final farewell to the F82 M4 before the next-generation model arrives in 2020.
The car looks like it has more aero work than the GT4 race car. It’d be cool to see a very high downforce BMW road car, and how that’d play out in this competitive field of road legal track weapons. That might also be the ultimate S55 under the hood, i reckon if it has 525PS then BMW would have the most powerful sub 3l engine out there ? All of this combined would make the CSL moniker come back with a bang !
A BMW M4 CSL? Bring it on…
Hope so! That would be cool! There will def be a CSL somewhere in the lineup
Ehh, public track testing of a new model without a hint of camo?
I think it’s more likely this is a tuner project getting tested.
Its an official prototype… so no.
