At Tesla's Semi event, the automaker dropped its new Roadster. It'll have a 620-mile range via a 200kWh battery pack."You'll be able to travel from LA to San Francisco and back without recharging," CEO Elon Musk said. The new Tesla Roadster will do zero to 60 in 1.9 seconds, and it'll blast through a quarter mile in 8.9 seconds, before reaching a top speed of over 250 MPH.

Oh, and it's a four-seater.
