When not accelerating, BMW's new Brake Energy Regeneration system stores engine power under braking or on a trailing throttle to charge the car's battery when required. It means the V8 can be both more efficient and effective when accelerating.

An optional MDrive button allows drivers to change a number of variables, which include selecting between three suspension settings (Normal, Comfort and Sports), three engine-mapping settings to change the V8's response and behaviour, and two power-steering settings (Normal and Sports).

The new M3 is based on the 3-Series Coupe, but BMW says only the two doors, bootlid, windows, headlights and rear lights are carried over.

Unlike the previous M3, the new model will also be available as a four-door sedan, while an M3 Convertible (with folding metal roof) and Touring (wagon) will create an even broader choice for buyers.

The new M3's interior features a sportier, thickly rimmed steering wheel than in other Three models, with 'M' badges placed subtly on the wheel, instrument panel and manual gearlever.

BMW Australia says the fourth-generation M3 will launch locally at the end of the year. Expect it to be priced somewhere between the $164,500 RS4 sedan and the third-generation M3 that started at $140,000.
