By the time I completed the 515-mile trip (513.8 to be exact), I had used 159 kilowatt-hours of energy. Considering the many stretches where I pushed the limits of the Performance model’s capabilities – and the average overall speed – I still managed a more-than-respectable efficiency above three miles per kWh. 

But the real kicker was the road manners of the Model 3. I would never have imagined how pleasant a compact car could be on a coastal highway. The level of interior comfort, roadway refinement, and passing power was on par with experiences I’ve had driving the coast in a Mercedes S-Class and Rolls-Royce. Not once did I worry about range.
