The 2016 Toyota Prius is the most fuel-efficient car Consumer Reports has ever tested

The 2016 Toyota Prius has better fuel economy than any car Consumer Reports has tested, besting the 16-year-old Honda Insight by a single mile per gallon. CR found the new Prius scored an average of 52 mpg, handily beating the 44 mpg made by the 2015 Prius.

That's because the new Prius is more aerodynamic, has a better battery, and uses that on-board electricity more efficiently. In a 65 mph highway test, the 2016 Prius achieved 59 mpg, a better rating than any diesel car the magazine has ever tested. In city tests, it notched 43 mpg.

When I drove the 2016 Prius last year, I said it isn't just a good hybrid — it's a good car. Now we know, thanks to CR's trustworthy testing, it's a fuel-sipping one, too.
