The efficiency of cars, with or without hybrid technology: An important UCS study from January 2003. Compared to today's 23 mpg US fleet average:

  • A fleet of passenger cars and trucks using conventional technology has the potential to reach a fleet average of 40 mpg. The average vehicle in this fleet will cost about $1,700 more in the showroom, but will save consumers $3,800 at the gas pump over the vehicle’s 15-year life for a net savings of $2,100.
  • A fleet of mild hybrids can reach nearly 50 mpg, with a retail price increase of about $2,900 by using advanced technologies available to automakers within this decade. Lifetime gasoline savings will amount to $4,700, producing a net savings of $1,500 for the average driver when the cost of battery replacement is included.
  • Full hybrids using advanced technology are the key to a passenger car and truck fleet that approaches an average of 60 mpg. The average price increase for such vehicles is about $4,000 and the owners will save nearly $5,500 on gasoline over the life of the vehicle. Including battery replacement, consumers would see an average net savings of $900. Plug-in hybrids would realize even greater energy security and environmental gains, but with higher costs and lower net consumer savings.
