Toyota proved it's got the fuel economy game wrapped up, as the Camry produced the best combined mileage of our test group with 43.2 mpg over both loops — 44.5 mpg in the city and 42.6 mpg on the highway. The Altima's fuel economy in the city actually proved marginally better than the Camry's at 47.3 mpg, but its 38.1 mpg on the highway dropped its combined rating to 40.1 mpg.
The Aura wasn't even close. Its combined fuel economy was just 26 mpg, largely as a result of its 18.9 mpg in city driving — where it doesn't benefit from true electric-only propulsion like the Camry and Altima. On the highway loop, the Aura produced 31.5 mpg.
Second, we calculated observed fuel economy over our entire time with each car, just as we do with all of our road test vehicles. Though this data isn't gathered in identical controlled conditions, it provides a useful idea of the fuel economy each car is likely to produce in the hands of the average drivers during everyday driving. The Camry again came out on top, producing 32.6 mpg. At 31.5 mpg, the Altima is a close 2nd, while the Aura lags behind at 24.5 mpg.
