It won't be officially unveiled until later this year, but we finally have our first look at — and details of — the Tesla Semi Truck. Company founder and big-thinker Elon Musk claims it will have more torque than any diesel semi, with the highest weight capacity and long range. Musk also claims you can drive it around like a sports car, thanks to its flat power curve and instant torque availability. Autonomous features are a lock and keeping them a secret is likely the reason why the first image is so dark. Expect more details about the rig to come out in September.
