2. 2013 Volkswagen Passat
The Passat has long been a favorite car of people looking for comfort, style and a long-lasting vehicle. With an MSRP starting at $29,020 it is quite the bargain. If you go with the six-speed manual transmission it produces a combined 35 miles per gallon (31 city, 43 highway) and is the most fuel efficient diesel car in the United States that we could find. Under the hood, it has a 2.0L turbocharged diesel engine. It is ideal for the entire family and has the room for your kids, pets and all the luggage space that you need. If you were to drive this car 15,000 miles in a year, the diesel fuel will only cost you about $1,700 (per the US Dept. of Energy).
