Drive modes are nothing new, however BMW could go for extra detailed customization in future efficiency EVs.
First noticed by CarBuzz, a current patent utility filed with the US Patent and Trademark Workplace (USPTO) goes past present drive modes, permitting drivers to tailor issues like throttle mapping and torque supply to dramatically change the habits of a automobile.
As a substitute of a restricted variety of modes like Sport and Eco with mounted settings, this technique would give drivers a graph from which they might select customized settings, in response to the applying. It takes benefit of the larger flexibility of electrical motors, which could be powered up or down in a linear style, like a dimmer change. And since most electrical powertrains use single-speed gearboxes, car pace extra instantly correlates to accelerator-pedal place.
Making the most of these qualities, BMW’s proposed system relies round acceleration and pace curves. The acceleration curve is just like the throttle mapping utilized in present internal-combustion vehicles, and the pace curve equalizes a sure pedal place to a sure pace. Each could be adjusted by dragging the curve line alongside a graph displayed on a car’s touchscreen, per the applying, which additionally means that BMW’s Hans Zimmer-designed EV sounds might shift relying on these changes.

As CarBuzz notes, there are just a few potential advantages to this technique. By selecting non-linear pace or acceleration curves, drivers might mimic the habits of an internal-combustion automobile, briefly disabling the flat torque curve inherent to an electrical motor in favor of the peaks and valleys of a gasoline engine’s torque curve. Automobiles is also programmed to speed up extra regularly than they’d in any other case, offering a security web for novice drivers or these not used to the facility or sudden acceleration of efficiency EVs.
Patented concepts do not all the time make it to manufacturing, however we all know that BMW is planning electrical M vehicles. It already sells the iX M60 and i4 M50, and not too long ago confirmed the 650-hp i7 M70. It has additionally teased fashions with extra intensive upgrades, together with a four-motor drivetrain.
