Applications are sought to develop new, lightweight alloys that provide a 25% improvement in component strength relative to components made with A319 or A356 and measured using standard material characterization techniques. To be considered a lightweight alloy for this application the density of the new materials must not exceed 6.4g/cm

And many of them are far from having MCS [the Megawatt Charging System, a new high-power standard for charging heavy-duty EVs]. This is far from the range that most diesel trucks offer, and a two-to-three-hour charge time is unacceptable to most drivers. Charged : So, Tesla is going to have MCS capability on the Semi.
