BMW M has started a new phase in its move towards the electrification of its car range.
The German car maker has started testing a concept vehicle as it seeks solutions for fully electric high-performance cars in the future.
"The concept testing focuses on a four-wheel-drive system comprising four electric motors and an integrated driving dynamics control system, which together provide an unprecedented level of performance and experience," it said.
It said the purely electric drive system is combined with innovative control systems to redefine the combination of dynamics, agility and precision.
BMW, which is celebrating 50 years of its high performance M brand, has already launched the all-electric BMW iLi MS0 performance car this year and the BMW iX M60.
The BMW i7 M70, the first BMW M car based on an all-electric luxury sedan, is to follow next year.
"Electrification opens up completely new degrees of freedom for us to create M-typical dynamics," said Dirk Hacker, head of development at BMW M.

BMW sees the high-performance character of the new drive system in the recuperation of braking energy.
"Right up to the limits of driving dynamics, the four motors can assume the function of a generator when braking before a bend, for example, and feed electricity back into the high-voltage battery," it said.
Car makers around the world are investing billions as they make the transition from combustion engines to all-electric vehicles.
Electric car sales for the first half of 2022 reached more than 3.5 million, IDTechEx research has shown.
China's EVE Energy Company will supply BMW with large cylindrical batteries for its electric cars in Europe, Reuters reported, as the company follows the likes of Tesla in adopting the new technology.
The shift by BMW, which currently uses prismatic batteries, highlights the growing momentum for larger-format cylindrical batteries.
