 The Elantra GT is NOT an enthusiast's car. It's an extremely practical car that provides commuters a quiet and comfortable ride in a relatively upscale cabin, with flexibility for carrying passengers and cargo, or for taking road trips. And with excellent mileage if driven conservatively.Gas mileage: by many accounts, the Elantra GT is unusually sensitive to how it's driven. At 60 mph with cruise control on, I get maybe 42 mpg. Mileage drops off sharply with additional speed, or with cruise control off. After a cold start, maybe 15 mpg for the first mile. When slowing, I take my foot completely off the gas to activate Deceleration Fuel CutOff.I've gotten right at 30 mpg on every tankful.
