Sadly, I find the following info to be a real bummer...
Customers will be most interested in Environmental Protection Agency fuel-economy ratings, which are 40/43 mpg (city/highway). That's 2 mpg less on the highway than the Civic Hybrid, and it trails the Toyota Prius by 8 mpg in the city and 2 mpg on the highway. The Insight qualifies as an Advanced Technology Partial Zero Emission Vehicle (AT-PZEV).
Come on, Insight getting less than the Civic??? And both hybrids...grrrr. Again we are screwed in getting a TRUE fuel mileage champion.
