The 2014 Toyota Corolla appeals to shoppers as much for its simplicity and price as it does for its fuel-efficiency. That said, some shoppers might want a hybrid system, Toyota's Prius lineup, as well as the Camry Hybrid, provide that in higher city miles per gallon.
Otherwise, the Corolla lineup returns the sort of mileage that price-conscious frugal shoppers will be happy with—easily well over 30 mpg in combined driving, with 40 possible on some models in the lineup.
That fuel-economy special of the lineup is the LE Eco. But if those numbers are the top priority, don’t load it up with options; if you get either the Plus or Premium packages, you’ll upgrade to 16-inch alloy wheels (rather than the 15-inch steel wheels), and that’ll knock 2 mpg off your highway estimate (40 vs. 42 mpg).
The LE Eco model also adds a new Eco Drive Mode button that brings further changes to shift points, throttle response, and accessory operation.
