Yes, and you're forgetting that the Model S has the equivalent of a 2 gallon tank to go ~260 miles. Big expensive stationary heat engines are still more efficient than small cost- and weight-optimized heat engines. >"In fact, some studies argue that the Tesla battery takes so much fossil fuel energy to make that the car over its lifetime emits more CO2 than a gasoline-powered car." That car being a Prius, not a comparable full-size sedan. The study also assumes a vehicle lifespan of 100,000 miles, or about 8 years of driving. I would be quite surprised if an all-aluminum car with few moving parts dies 3 years before the average age of cars on the road today (11.4 years).

Edit: digging deeper, their whole argument ultimately rests on this report: http://pubs.acs.org/doi/abs/10.1021/es103607c http://pubs.acs.org/doi/abs/10.1021/es103607c GreenCarCongress reviewed it, saying >They also found higher life cycle global warming emissions than have been previously reported. http://www.greencarcongress.com/2011/04/ntnu-20110421.html http://www.greencarcongress.com/2011/04/ntnu-20110421.html
