The Leaf's new heater is going to help with range, even if it wasn't designed to beat the government's mileage test, as it were. Perry tells the Detroit newspaper, "You may not see much change on the EPA rating, but in cold-weather conditions you may see 20 to 25 miles of improvements."
This brings us to the big question: will Leaf sales also increase in 2012? Thus far, the trend hasn't been great, dropping to 676 sales in January and then 478 in February. In some months of 2011, Nissan sold over 1,000 Leafs. There are annual variations in sales patterns, and Perry tells The Detroit News that he expects Leaf sales to cross 2,000 a month in the U.S. some time this summer, a prediction that sounds reasonable given that the model will now be available in all 50 states.
