How does the BMW iVision achieve its range sustainability?

I am interested in understanding the technology behind the BMW iVision's impressive range sustainability. Can someone explain how this is achieved?

The BMW iVision uses a combination of lightweight construction materials, aerodynamics improvements, and energy-efficient drivetrain technology to achieve its range sustainability. By reducing weight and improving energy efficiency in these areas, the iVision is able to maximize its range on a single charge.

One key factor in the BMW iVision's range sustainability is its use of regenerative braking. This technology captures and stores energy that would otherwise be lost during braking, helping to recharge the battery and extend the vehicle's range.

In order to optimize the BMW iVision's range, it's important to drive conservatively and minimize energy usage. This includes avoiding hard acceleration and braking, using the vehicle's regenerative braking system effectively, and planning efficient routes.
