Mitsubishi Mirage

Best for Budget Buyers: Mitsubishi Mirage

As one of the cheapest cars with the best gas mileage, the Mirage is perfect for city driving and long commutes. The subcompact Mirage hatchback is one of the least-expensive vehicles available on the U.S. market. Fortunately, it’s also one of the most economical to run, with its 1.2-liter engine capable of 43 MPG on the highway when equipped with the continuously variable automatic transmission (a five-speed manual is standard). The Mirage’s hatchback body has plenty of room up front and a versatile cargo area that can be expanded by folding down the back seats. Its super-tight turning circle makes it a great car for the city. Even at its low base price, the Mirage comes standard with ABS brakes, stability control, and automatic braking with pedestrian detection, features which are optional on many more expensive cars. Seven airbags and a rear-view camera are also standard, as is a 10-year, 100,000-mile powertrain warranty.

  • Starting MSRP: $16,695
  • EPA Estimated City/Highway MPG: 36/43

Most Fuel-Efficient Non-Hybrid: Volkswagen Jetta

The Jetta is a compact sedan with almost as much room as a mid-size sedan. It stands out as one of the most fuel-efficient cars that aren’t hybrids, offering 43 MPG on the highway with a turbocharged engine. In fact, everything about it feels like it’s from a class above, from its spacious interior to its big, comfortable seats, to its superb ride quality and the quiet cabin. From the moment you turn the steering wheel, you can sense the Jetta’s autobahn breeding: it’s stable and comfortable at highway speeds with superb refinement for a car of its price. The 1.5-liter turbocharged engine produces a thrilling rush of speed while sipping gas. Its 158 horsepower is nearly double the Mitsubishi Mirage’s, while delivering great fuel economy.
