At a technical presentation in Germany, BMW explains how batteries, motors and innovative components are transforming its future.

BMW's managed to increase the efficiency of its next-generation electric powertrain by 20 per cent versus what's on sale today. As Daft Punk didn't say in their 2001 electro-pop hit, the Neue Klasse series powertrains will be (energy) denser, lighter, faster and smaller.

That range boost can’t come soon enough for some BMW EVs. The new iX2 xDrive30, for instance, has a WLTP rating of less than 285 miles (460 km). And the automaker says certain models will see range gains better than 30 percent. All Gen6 EVs will also be capable of bi-directional charging.
