As we learned a while ago, the BMW i7 will have an M performance variant, called the i7 M70. Although there are no official details from BMW, the German Sport Auto BMW i7 M70 has revealed some possible details about the powertrain and its horsepower.
According to this new report, the BMW i7 M70 will produce at least 700 horsepower from its all-electric powertrain. As for the actual powertrain / battery, there is no description but it is entirely possible that it gets the same powertrain as the upcoming Rolls-Royce Specter. From what we understand, Specter is going to use a quad-motor setup, an electric motor that powers each individual wheel.
Not only will this give the BMW i7 M70 immense power, it will also give it real-time, individual wheel torque vectoring. This type of rotating force vector will provide the best possible performance in both straight lines and angles, as well as improve its traction in bad weather.
However, it seems doubtful that the BMW i7 M70 will use the same powertrain as the Rolls-Royce Specter. All new Rolls models use their own engine – a 6.75 liter twin-turbocharged V12 – and the British brand was adamant about not using a BMW engine to distinguish itself from the Bavarian brand. Which leaves us wondering if Rolls would like to keep his powertrain unique from BMW. Of course, if the BMW Group decides otherwise and gives the i7 M70 a specter powertrain, that is what will happen. However, it would be understandable to allow Rolls to keep the most powerful, most advanced electric powertrain under the umbrella of the BMW Group.
While this happens, and the BMW i7 M70 gets a quad-motor, 700 horsepower electric powertrain, it will be one of the most powerful cars in the brand’s history (only the BMW XM will have more, with 750 horsepower). The BMW won’t make a perfect M7 but an i7 M70 will be close enough.
