With the the efficiency gains that the Dual motors has brought to the drivetrain, I was wondering, what else could Tesla do to improve eficiency? These are my guesses. Base range: 275 miles. + 5% by removing side-mirrors + 5% by installing regenerative suspension. + 5% by installing solar cells in the entire body of the car (on a sunny day) + 10% by reducing weight + 5 % more efficient wheels. + 5 % by covering the wheel-houses. 275*1.05*1.05*1.05*1.10*1.05*1.05= 386 miles ! 386 miles without increasing the capacity of the battery. What do you think?
