Despite some delays, as promised Elon Musk finally rolled in to reveal Tesla's new all-electric truck, the Tesla Semi. The big rig goes from 0 to 60 in 5 seconds and tows a max load 80,000 lbs with an estimated range of 500 miles on the highway. A range of 400 miles can be had in 30 minutes on a single charge from solar powered "Megachargers" the company plans to build.
