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.

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.
