2011 Chevrolet Colt
The 2011 Chevy Volt plug-in hybrid is arguably the most fuel-efficient car on the market, but it's pricey for what you get. Low monthly fuel cost in normal driving; useful 300-mile maximum range; appealing standard features; high-tech cabin. Questionable value; small backseat for two people only; touchy brakes; no power front seats; home charger is a necessity.
