Seventh gen BMW M5 gets electric boost up to 727 hp

After 40 years, the seventh generation of the BMW M5 gets a combination of a high-revving V8 engine with M TwinPower Turbo technology and a specific version of the M HYBRID system, boosting power to 535 kW or 727 hp and a peak system torque of 1,000 Nm.

The world premiere will take place at the Goodwood Festival of Speed in the UK in July 2024, and the worldwide market launch – also of the Touring – in November 2024

69 km pure electric

For the first time, the BMW M5 features a battery of 18.6 kWh usable energy that allows for a pure electric range of 67 – 69 kilometers and a top speed of up to 140 km/h. Combined with the V8 power, the speed is limited to 250 km/h, but the limiter can be raised to 305 km/h.

It’s nice for your wallet that fuel consumption (WLTP) is limited to 1,7 – 1,6 l/100 km instead of 10,3 – 10,2 l/100 km when your battery is depleted. It softens the price of around €130,000, which you’ll have to pay initially to get it, but that’s considered amazingly ‘reasonable’ for the type of car you’ll get.

500 kg extra weight

Petrolheads generally don’t trust electric systems, as the extra 500 kg weight of up to 2,510 kg compared to the previous M5 is feared to compromise its agility. Acceleration figures of 0 to 100 km/h in 3.5 seconds suggest at least there is little to worry about performance.

The 145 kW/197 hp electric motor, built into the eight-speed M Steptronic transmission, adds immediate torque, the primary benefit of any electric car to an already impressive sports car. BMW says this M Hybrid system, plus power transmission, four-wheel drive, and chassis technology tuned to its specific performance characteristics, gives the new M5 transverse and longitudinal dynamics unparalleled in this market segment.

Five driving modes

The BMW M5 Hybrid gets three standard driving modes or five as an option by using the M Hybrid button on the control panel in the center console and accessing it on the control display.

In Electric mode, the V8 engine is only activated when the driver asks for a lot of power with a kickdown. Battery capacity can be saved for pure-electric driving in urban areas by a setting that allows the charge to be maintained at a constant level or increased using energy recovery or by deliberately raising the combustion engine’s load points.

The default ‘Hybrid’ setting gives the driver access to the entire system output of the combustion engine and electric motor in tandem. In the ‘Comfort’ mode, the electric motor is fully deployed, optimizing the efficiency of the BMW M5.

Generator function

When the battery is at a deficient state of charge, the generator function raises the engine’s load point to feed additional power into the high-voltage battery. This means the driver
very often has the option of pure-electric driving.

For those who love raw sports performance, the optional M Drive Professional adds Dynamic and Dynamic Plus modes. These ensure the combustion engine and electric motor are both active and that the cooling system is conditioned for track driving. Dynamic Plus is there for those who want to have their cake and eat it: getting maximum power for a brief period on a grand-prix circuit, for example.

Petrolheads loving the roar of a wild V8 don’t have to fear this ‘electrified’ M5, as a newly developed and model-specific sports exhaust system “conjures an emotionally rich and energy-charged aural accompaniment to the engine’s power delivery,” according to BMW.

There is even an M-specific electric drive sound—BMW Iconic Sounds Electric—which provides authentic responses to accelerator movements when the car is operating in all-electric mode.
