2025 BMW M5: Key Updates and Hybrid Powertrain

BMW has introduced the 2025 M5, which now incorporates a plug-in hybrid system combining a petrol V8 engine with an electric motor.

The model is set to arrive in Australian showrooms between October and December 2024, with local pricing to be disclosed in July.

The new M5 features a 4.4-litre twin-turbo V8 engine, labeled the 'S68,' which is shared with the XM SUV. This engine generates 430kW and 750Nm.

An electric motor integrated into the eight-speed automatic transmission increases the total system output to 535kW and 1000Nm.

This update makes the 2025 M5 the most powerful version in its 40-year history.

The hybrid system adds significant weight, with the M5 now weighing 2435kg, an increase of 540kg over its predecessor.

BMW claims a 0-100km/h acceleration time of 3.5 seconds. The M Driver’s Package, standard on Australian models, raises the top speed to 305km/h.

The vehicle can drive up to 69km on electric power alone, thanks to an 18.6kWh lithium-ion battery pack, and includes an acoustic noise generator for low-speed electric driving.

The exterior design includes a single bar kidney grille, larger lower air intakes, angular side vents, and a rear diffuser with four 100mm exhaust tips.

The dimensions have increased, with the new M5 measuring 5096mm in length, 1970mm in width, and 1510mm in height.

The car also features new wheels, measuring 20 inches at the front and 21 inches at the rear, equipped with 285/40 and 295/35 tires, respectively.

Inside, the M5 features BMW’s Curved Display, which combines a 12.3-inch digital instrument cluster with a 14.9-inch infotainment screen.

The system supports wireless Apple CarPlay and Android Auto, along with other connectivity features like over-the-air updates and the My BMW App.

A head-up display is standard. The seats are upholstered in Merino leather, and the interior includes a flat-bottomed steering wheel with multiple control buttons.

Safety features include adaptive cruise control, lane departure warning, blind-spot assist, and a surround-view camera.

The M5 also includes advanced driver assistance systems like lane-keep assist, speed sign recognition, and rear cross-traffic assist.

Performance-wise, the M5’s hybrid system is derived from the BMW M Hybrid V8 racecar.

The car includes an electronically controlled sports exhaust with four outlets, adaptive sports suspension, and a bespoke chassis tune.

The hybrid system can be traced back to the BMW M Hybrid V8, used in World Endurance Championship races.

Details about the BMW M5’s Australian specifications and pricing will be announced next month.
