The new battery technology upgrades the lithium ion cell which was state of the art in 2008 and the first put into a production vehicle, to produce 31% more energy and around 70kWh. Thanks to a retrofit aero kit, its drag coefficient has improved by 15% to drop down to 0.31, and the rolling resistance coefficient has also been bettered to 8.9 kg/ton instead of 11.0.
