BMW_Concept_M4_GTS_Malaysia_ 001

The BMW Concept M4 GTS made its second-ever public appearance right here in Malaysia, after its global debut at the Pebble Beach last month. It’s on display as part of the on-going BMW M Track Experience Asia 2015 event at the Sepang International Circuit.

Don’t quite know what this M4 GTS is? It’s a thinly disguised preview of an upcoming lightweight, track-optimised version of the F82 M4 coupe that will go on sale next year, much in line with the previous E92 M3 GTS, E90 M3 CRT and E46 M3 CSL. You can pretty much ignore the Concept tag here.

On the outside, the Frozen Dark Grey Metallic M4 gets a prominent carbon-fibre front splitter with a dash of Acid Orange paint, which is also generously applied on the staggered ‘666 M’ light alloy wheels (19-inch front, 20-inch rear).

At the back, there’s a massive adjustable GT wing, along with a carbon-fibre rear diffuser. The taillights are unique too, as they now feature BMW’s OLED (organic LED) technology that allows for “full-surface and homogenous illumination.” Looks good in the flesh, that’s for sure.

No output numbers have been revealed just yet, but the Concept M4 GTS has adopted the new water injection system first seen on the 2015 BMW M4 MotoGP Safety Car. The system effectively pumps water into the plenums of the intake manifold, allowing for a lower air temperature.

The result is reduced compression temperature and likelihood of engine knocking. All this should add up to more power and torque along with improved engine reliability. The cooling systems for the engine, transmission and turbocharger have also been upgraded.
