2012 Chevrolet Cruze Fuel Mileage Goes Up When Slowing Down

By Trevor Dorchies | June 24, 2011
With fuel prices being as unstable as they are, and with stricter government mileage ratings looming, automakers have been doing everything they can to improve the MPGs of their lineups.  Chevy especially has been hard at work boosting the mileage of its Chevrolet Cruze, and starting with the 2012 model the Cruze will get a 2 percent increase in fuel economy, adding another 17 miles to the Cruze ECO’s overall range. All non-ECO Cruze models will add another 11 miles overall to the range. This improvement in fuel economy is courtesy of a technology called deceleration fuel cutoff (DFCO). As the Cruze slows down, fuel is shut off automatically going to the engine and begins to flow again when the pedal heads toward the floor. DFCO is also active when the Cruze is coasting and the accelerator is not touched. The engine controls its speed through the integration of engine and transmission controls. Both automatic and manual transmissions will come with DFCO to help stretch out fuel economy. Cruze models equipped with the 1.4L turbo and six-speed automatic transmission will get a 2 mpg boost in fuel economy. The Cruze Eco outfitted with an automatic transmission can get as much as 39 mpg on the highway compared to the 37 mpg the 2011 model achieves. The Cruze Eco that comes with the standard six-speed manual transmission touches 42 mpg on the highway.
Manufactured to battle compact class heavyweights like the Toyota Corolla and Honda Civic, the Cruze surpasses both the Corolla and non-hybrid base Civic in miles per gallon with the help of technology like DFCO. Another appealing feature about the 1.4 turbo is that unlike most turbo engines, the Cruze can be filled up with regular unleaded fuel. It’s also a little quicker than its main competitors, with Chevy claiming the manual ECO can scoot from 0-60 in 9.1 seconds, several ticks better than the base Civic’s 9.8 second and Corolla’s 10.0 second times.
