SANTA MONICA, Calif., March 10, 2011 /PRNewswire/ --, the authority on new car pricing, trends and forecasting has compiled a list of the top ten most fuel-efficient cars currently being sold, based on fuel economy and cost of gas, per 15,000 miles driven annually. Of the top ten, nine vehicles were hybrids, with the 2011 Toyota Prius being the most fuel-efficient vehicle and the 2011 Hyundai Elantra making the list as the only non-hybrid. Pure electric vehicles were excluded from the list because there is no cost associated with filling up a tank.


When looking at the vehicles, based on annual fuel costs and price, the 2011 Toyota Prius (base) average price paid is $22,235 and costs $1,064 annually based on the current price of $3.52 per gallon of unleaded fuel and 15,000 miles driven annually. The 2011 Hyundai Elantra (base) is 32 percent cheaper than the 2011 Toyota Prius (base) at $15,052, based on average price paid, yet costs only $531 more to fill up annually.

"When purchasing a fuel-efficient vehicle, consumers should consider two factors – price and annual cost of fuel," said Jesse Toprak, Vice President of Industry Trends and Insights at "If you're looking for the most fuel-efficient car, the Toyota Prius wins. If you're looking for the most cost-effective and fuel-efficient car, the Hyundai Elantra is the clear winner."'s top ten most fuel-efficient cars are:
