Headlining the unveiling is the new Concept M4 GTS, a muscly makeover of the still-new M4 Coupe that BMW has dressed in a cool grey finish with contrasting orange highlights - and, of course, a load of aerodynamic and under-the-skin enhancements.
BMW has also identified the concept coupe as a technology preview for a coming new production model, “to be unveiled at a later date”.
Expect that model to wear the same M4 GTS name as this concept, following the M3 GTS models of generations past.
Features starring in the concept and promised to debut with that new model include the same water-injection system that delivered improvements in performance and fuel consumption for the recent M4 MotoGP Safety Car.
Exact numbers are still to be confirmed, although BMW claimed an eight percent improvement for the MotoGP car.
In its standard form, the 317kW/550Nm M4 lists a 0-100km/h time of 4.1 seconds and fuel consumption figures of 8.3 l/100km.
The concept also features OLED (organic light-emitting diode) tail lamps - tech which first appeared on the M4 Iconic Lights concept in January and may also appear on the final production model.
Importantly, BMW’s M division claims that nothing about the Concept M4 GTS would keep it from being eligible for use on public roads.
“While the BMW M4 Coupe embodies the ideal combination of motor sport genes and unrestricted everyday usability, the BMW Concept M4 GTS previews an emotionally powerful and exclusive special model conceived with an eye for trailblazing technology and a keen focus on the race track,” BMW M president Frank van Meel said.
“Despite its outstanding track ability, it is still fully road-legal. This is racing technology for the road in the truest sense.”
Joining the M4 GTS concept this week is the new 3.0 CSL Hommage R concept, revealed in May - without the racing ‘R’ - and refreshed this week with BMW M’s familiar racing livery and a handful of other tweaks.
Leading those changes is that famous white body colour with the navy, light blue and red striping familiar to BMW M fans and rivals alike.
There’s also a new mesh grille in place of the concept’s earlier louvred design, and a new racing gold finish to the large multi-spoke alloy wheels.
The new theme continues into the cabin, where the existing design has been revised with the same white and striped treatment that adorns the exterior.
Unlike the M4 GTS, the new 3.0 CSL Hommage R is not scheduled for production anytime soon - but BMW isn’t beyond declaring it a potential preview of the company’s future styling.
“Motor racing is all about the ability of cars to mesmerise, about the unbridled joy of driving,” BMW design chief Adrian van Hooydonk said.
“As such, it represents the heartbeat of BMW. Back in 1975, as today, winning races came down to how man and machine could work together. Technical innovations have taken the effectiveness of this partnership to ever great heights. And with the BMW 3.0 CSL Hommage R we’re aiming to show how much closer the driver and car can grow in the future.”
