For decades, it has ruled as the armor donned by supercar heroes, but the BMW M4 GT4 Evo is set to change the game with a carbon fiber replacement as the German manufacturer has showcased a new natural flax composite.

We’ve seen a ton of advancements in the car manufacturing processes in the last few years alone.

With motors and batteries being placed under the microscope, scientists, engineers, and technicians have all been trying their damndest to make cars better.

However, BMW has now targeted its supercars and sports cars for an area of improvement, introducing a new carbon fiber replacement.

BMW M4 GT4 Evo debuts new natural flex

Carbon fiber is often the benchmark between true car royalty and those who play pretend.

Tuning companies and manufacturers with limited-edition ranges often save the carbon fiber bodywork for specialist models and upgrades, such as the 400th Bugatti Chiron or Novitec’s spruced McLaren 765 LT.

But BMW is now opting to use a new composite called ‘natural flax’ for its bodywork, and its recent victory at the Nürburgring 24-Hours race last week saw it on full display.

The BMW M4 GT4 Evo in question saw its dashboard, center console, hood, front splitter, doors, trunk, and rear wing made of a renewable and high-performance natural flax composite

“Natural fiber is an innovation that perfectly exemplifies BMW M’s claim: ‘Born on the racetrack. Made for the streets’,” said CEO, Franciscus van Meel.

The CEO also revealed that the M Series will continue to use the natural flax, hot on the back of BMW’s win during the race.

Why are we searching for a carbon fiber replacement?

BMW is leading the charge with a carbon fiber replacement, and it comes from deliberation in the EU Parliament around the safety of the materials used.

Carbon was classified as ‘harmful’ by a report laid out in front of the Parliament, with a ban on carbon fiber being discussed as early as 2029.

Instead, the natural flax is supposed to be 40 percent greener, having trialed the materials in Formula E since 2019.

Performance is clearly not being impacted, as the BMW M4 GT4 Evo won its race around the Nürburgring, and if it makes the world a better place, who would say no to this carbon fiber replacement?
