The 2014 Toyota Yaris has adequate although not stellar fuel economy for a subcompact. If you’re looking for the most fuel-efficient car in the category, that would be its sibling, the Toyota Prius C—at a price that starts just under $20,000.
The Yaris is rated at 33 mpg combined (30 mpg city, 37 mpg highway) with the five-speed manual gearbox, and 32 mpg combined (30 mpg city, 36 mpg highway) with its outmoded four-speed automatic transmission. It’s one of very few cars left on the market without a five- or six-speed automatic, and that’s likely one of the factors that prevent it from reaching the magic 40-mpg mark on highway fuel economy.
In our road test of the Yaris, we were able to average 30 mpg during a route comprising almost all city stop-and-go and short trips. But in highway use at a steady 70 mph, we could only average 35 mpg.
