The Mini brand is going all-electric. We expect the next generation of Mini, starting with the 2025 Mini Cooper Hardtop, to be available with an internal combustion engine or an electric drivetrain. But parent company BMW says the Mini brand will be 100% electric by 2030.

Most Mini models aren’t known for their engine sounds. But fans love the little revving sound of the 2.0-liter turbocharged 4-cylinder found in the John Cooper Works edition of the current car. It will be missed.

But it will also be replaced.

Mini explains that its upcoming electric cars will get “sound worlds distinctive to the brand for an even more immersive driving experience.”

The sounds will be “individually tailored to the character of each of the new models,” says Oliver Heilmer, head of Mini design. You’ll hear them first in the 2025 Cooper EV.

It’s all a little hard to imagine. But sound design is becoming a normal part of car design in the EV age. BMW hired famed movie soundtrack composer Hans Zimmer to create sounds for its current lineup of EVs. Porsche, meanwhile, will let the car do the composing. The company’s upcoming Soundtrack My Life system creates music that constantly shifts in response to driving style.

Four Modes and One Renaissance Polymath

The car will offer four driving modes – Core, Go Kart, Timeless, and Balance. Each of the four will come with an acoustic signature.

Those outside the car will always hear the same thing. The Core driving sound, Mini says, “sounds inviting, energetic, and inspiring.” Unfortunately, they haven’t provided audio samples to the press. Just descriptions that, well, can be a bit odd.

Renzo Vitale, creative director of sound at the BMW Group, says the Core sound is “inspired by Nicolaus Copernicus, who depicts the heliocentric view of the world in which the planets revolve around the sun.” We’re sure you can imagine it based on that.

Vitale says it varies “depending on the driving situation.”

Switch to Go Kart mode, and those outside the car still hear the sounds of a 15th-century Prussian mathematician. But inside, the driver gets “strongly pronounced pitch and load curves, forming a fitting sound backdrop for agile and dynamic driving.”

Timeless mode, as you might have guessed, draws on Mini history. After all, the 2025 Cooper gets an interior inspired by the 1959 British Motors Corporation Mini. So the Timeless mode’s soundscape melds the engine sounds of several classic Mini models, and the Core mode’s futuristic whirs “to create an acoustic journey through time.”

The final setting, Balance, “is based on the sounds experienced in a forest at different times of the day and night: from the babbling of a stream to the chirping of crickets and the rustling of the wind in the treetops. The resulting worlds of sound give a sense of relaxation and well-being on board the future Mini models.”
