The demonstration vehicle Tesla showed reporters at the carmaker's Torrance, Calif., headquarters had a few features that might not make it into production, including cameras that act as side view mirrors. Doing away with side view mirrors would improve the SUV's aerodynamics and significantly increase driving range, said Musk. Safety regulations might stand in the way, though.
The Model X will be available in both rear- and four-wheel-drive versions. The four-wheel-drive version, which will use two independent electric motors, will have a zero-to-sixty acceleration time in the 4.4 seconds, Musk said.
