26 mpg city, 35 highway (manual 1.8); 25/35 (auto 1.8); 29/40 (manual 1.4T)
the Sonic weighs in at some 2800 pounds, a good 300-pounds more than most entries in the segment
It's not the single most fuel-efficient subcompact on the market--that'd be the Toyota Prius C hybrid--but the 2014 Chevrolet Sonic will deliver real-world gas mileage of 30 to 35 mpg when fitted with the optional 1.4-liter turbocharged engine. It's optional (on LT and LTZ models) and rated at 31 mpg combined with the automatic transmission, rising to 33 mpg with the six-speed manual.
If you drive sensibly, you can most likely do better than that--we got 34.2 mpg over several hundred miles in a 1.4 sedan with the six-speed manual gearbox. And the turbo--unlike many earlier such engines--doesn't require premium fuel, but is quite happy on regular unleaded gasoline.
The base 1.8-liter engine costs less, but it drinks more fuel. Its ratings are a less respectable 30 mpg combined with the manual, falling to 28 mpg with the automatic. It's also less fun to drive, so we think the payback is pretty clear.
While it's never going to be a Prius hybrid, the 2014 Chevy Sonic delivers real-world mileage in the 30s with the 1.4-liter engine
