GM released the official fuel economy numbers for the 2011 Chevrolet Cruze Eco. So, the new car was rated by EPA to 42 mpg on the highway (manual transmission models) and 28 mpg in the city.
With these numbers, the 2011 Cruze Eco beats the competition, such as the Honda Civic, or the Ford Fiesta subcompact but also many hybrid models like Ford Fusion Hybrid, Nissan Altima Hybrid and Toyota Camry Hybrid.
For those who don’t know, the 2011 Chevrolet Cruze Eco is powered by a 1.4-liter turbocharged engine delivering 138 horsepower (103 kW) and 148 lb.-ft. of torque (200 Nm) between 1,850 rpm and 4,900 rpm, and mated to a six-speed manual transmission.
A six-speed automatic transmission is also available, with EPA-estimated fuel economy ratings of 26 city and 37 highway. If you want this car, the 2011 Cruze Eco will carry a base price of $18,895 (including destination charge), and it will go on sale in January 2011.
2011 Chevrolet Cruze has an EPA-estimated highway fuel economy of 42 mpg, six mpg of which could be attributed to the aerodynamic improvements done on its non-Eco manual-transmission models. A number of these improvements were developed and then refined resulting from the more than 500 hours of testing the Chevy Volt on wind tunnels.
Volt has similar core architecture with that of the Cruze. Some of these improvements are the upper grille with more "closeouts". Then there is the front air dam extension and ride height, both of which have been lowered.
The underbody panels have been lowered as well ensuring that there is smooth airflow under the car. There is also the rear spoiler. The Eco model also has new technologies for a compact car. Lower as well, the front grille has air shutters that are able to open when at lower speed in order to optimize the airflow and cool the engines while it closes when at higher speeds to reduce drag.
Reducing the drag as well are the lightweight wheels with the 17-inch Goodyear tires which have ultra-low rolling resistance.
Because of these different improvements, the aerodynamic drag was lowered by 10% compared to the non-Eco model leading to a 0.298 coefficient drag. This is why the Cruze is at the top when it comes to mainstream compact cars.
