17 Fuel Efficient Cars

17. Cadillac ELR

Fuel efficiency: 82 MPGe

There was a time that the Cadillac brand would have never been thought of when it came to fuel efficient automobiles. With the entry of the Cadillac ELR into the market; however, things have changed. The car sees an impressive 82 MPGe and is a plug-in hybrid. The MSRP for the vehicle is $75,000 before the Federal tax rebate is applied, and the battery is capable of supporting an “electric only” range of 37 miles. The ELR also sees a respectable 33 MPG when running only on gasoline, and looks to make a big splash in the luxury car market.
