Saving fuel

New cars are getting better fuel economy than ever. And with government fuel economy standards rising to 54.5 mpg by 2025, that trend looks sure to continue well into the future.

Technologies such as smaller, turbocharged engines with electric accessories, idle-stop, and multi-speed or continuously variable transmissions are proliferating, along with hybrid drive systems and lightweight materials. All together, these technologies are bringing small-car fuel economy to midsized family sedans and even some SUVs.

This section reveals the best and worst models for fuel economy based on our tests, and it shines a spotlight on which gas-saving vehicles and technologies make the biggest difference with the fewest tradeoffs in space, utility, comfort, and performance. Learn how to save fuel now.
