How can you know, with certainty, how efficient one car is versus another? We conducted a “well-to-wheel” accounting for all fuel efficiency and emissions of several types of high-efficiency cars, including an estimate for the Tesla Roadster, based upon performance prototypes.

Here‘s what we found: the Tesla Roadster offers double the efficiency of popular hybrid cars, while generating one-third of the carbon dioxide. Compare the Tesla Roadster against other sports cars and the results get better still: it is six times as efficient and produces one-tenth the pollution, all while achieving the same performance and acceleration.
