The three electric motors are powered by a lithium-ion high specific power (4500 W/kg) battery pack that also supports a fully-electric drive mode. As well as a monocoque made entirely of multi-technology carbon fiber, it features a front structure in Forged Composites; a special material made of short carbon fibers soaked in resin.
