Observed Fuel Economy:
EPA estimates for electricity consumption in the Model S were 38 kWh/100 miles, with a range of 265 miles on a full charge. Our best observed range was 230.4 miles and the best projected range was 264.2 miles. The best average energy for a single charge was 238 watt-hours per mile (23.8 kWh/100 miles) and the worst 344 watt-hours per mile (34.0 kWh/100 miles).
The energy usage calculations do not include charge losses, which are 25-35 percent based on our experience with the high-powered wall connector (HPWC)."

Cons: Extensive list of repairs necessary, interior amenities don't match other luxury sedans in its price range, latest active safety systems not available, needs at least a Level 2 charger to make it useful as a daily driver.
Bottom Line: The Model S is a fast, comfortable and technologically brilliant luxury sedan,
but numerous problems with its touchscreen, tires and drivetrain make it hard to recommend.[...]"
