Tesla reveals more details of Roadster powertrain v1.5
JB Straubel, Chief Technical Officer Tesla Motors, recently posted an update on the progress of powertrain 1.5 on the company's blog, and be warned, if you're not up to date on how highly complex electric motors and transmissions work (like us), you'll probably get lost. The basic nuts and bolts of it amount to a Tesla Roadster that will have both a 33% higher peak torque output and an additional 10 miles of range versus the 1.0 car. According to our own Sam Abuelsamid who has followed the Tesla Roadster's development from gestation, these two seemingly irreconcilable accomplishments were achieved mainly through lowering resistance at every point along the powertrain. This was done by redesigning some components, using low resistance materials and switching to a new, shorter gear ratio of 8.27:1. You can read Sam's nitty gritty explanation of the changes over at AutoblogGreen, but it seems the little EV company that could is finally getting back on track after some major set backs.
