BMW Working On New Engine For M3

In an interview with Top Gear, BMW Neue Klasse project head Dr. Mike Reichelt revealed new details about the next M3, which will arrive after the Neue Klasse 3 Series launches in 2026.

“We’re also going to offer [the M3] with a new type of six-cylinder engine,” Reichelt said. “We understand it may be early for some committed M fans to make the switch [to EVs].”

The current M3 uses the company's S58 twin-turbocharged 3.0-liter inline-six engine, which produces 523 horsepower in the M3. BMW wasn't forthcoming with specifics about the new combustion engine; it’s expected to be more powerful than the current version and could incorporate hybrid technology to match the EV’s expected 700 hp output.

Reichelt confirmed both versions of the M3 will share the same design and digital features, despite the differing powertrains.

The next M3 will also debut BMW’s new "Heart of Joy" performance controller, an integrated drive management system first shown on the Vision Neue Klasse concept. “It’s no longer about making a car that has the fastest 0–62 mph time,” Reichelt said, “but rather a car that offers precise dynamics.”

The system combines management of the drivetrain, braking, steering, and regenerative energy into one control unit capable of processing data 10 times faster than before.

“We want to test the Heart of Joy and see what is possible on the physical side - not just the dynamic effects, but in everyday use. In complex weather conditions, like snow or ice, one advantage is that it’ll help the car move into a corner with the first input of steering. It’s as if the car knows what you want it to do, and that will have a big impact when the weather gets tricky.”

While the standard Neue Klasse 3 Series is expected to debut later this year and go on sale in early 2026, the M3 version won’t arrive until late 2026 or early 2027.
