Last week Tesla Motors unveiled the Tesla Semi, and in a "one-more-thing" moment, they also unveiled the Tesla Roadster2. The Semi is perhaps the more important vehicle, and in any case the guy behind the KmanAuto YouTube channel was at the unveiling, and managed to sneak underneath the truck to take this video. The drive train - motors, gearboxes, wiring, etc - was all exposed underneath the truck, and Kman was able to post this 5-minute video tour of the parts. In a second video he demonstrated that the charging port is NOT the same as a Supercharger port, meaning it's gonna be a different charging cable and connector for the MegaCharger.
