(November 12, 2010) DETROIT — The official fuel economy numbers for the 2011 Chevrolet Cruze Eco are in and they’re good. Segment-leading good. It delivers an EPA-estimated 42 mpg on the highway (manual transmission models), with equally impressive city fuel economy of 28 mpg.

Cruze Eco’s highway fuel economy beats non-hybrid segment competitors — including 23 percent greater highway fuel economy than the Honda Civic – as well as the Ford Fiesta subcompact and many hybrid models. In fact, it’s better than Ford Fusion Hybrid, Nissan Altima Hybrid and Toyota Camry Hybrid.

“Chevrolet Cruze continues to redefine the compact segment, offering class-leading standard safety features, upscale amenities – as well as hybrid-like fuel economy without the price,” said Chuck Russell, vehicle line director. “The Cruze Eco is in a league of its own and will challenge perceptions of the efficiency available in a more affordable non-hybrid.”

The Cruze Eco carries an MSRP of $18,895 (including destination charge). It goes on sale in January.

To achieve its segment-leading fuel economy, Cruze’s engineers focused on aerodynamic performance, mass optimization and powertrain enhancements. The refinements in each area paid big dividends towards the car’s overall efficiency, while providing engineers with valuable information to help enhance the efficiency of future Chevrolet models.

“We left no stone unturned or piece of sheet metal un-weighed,” said Russell. “Our engineers were comprehensive and thorough when it came to evaluating and modifying the aspects of the car’s performance that contribute to fuel economy.”

Aerodynamic improvements over non-Eco manual-transmission models contributed approximately six mpg to the Cruze’s EPA-estimated 42 mpg highway fuel economy. Many were developed and refined in more than 500 hours of wind-tunnel testing of the Chevy Volt, which shares a core architecture with the Cruze. Examples include the upper grille, which has more “closeouts” to improve aerodynamics, a lower front air dam extension, a rear spoiler, a lowered ride height and underbody panels that smooth airflow beneath the car.

The Eco model also features an all-new technology in the compact segment: a lower front grille air shutter that closes at higher speeds to reduce aerodynamic drag and opens at lower speeds to optimize engine-cooling airflow. Another contributor to reduced drag is the use of ultra-low rolling resistance 17-inch Goodyear tires (used with lightweight wheels), which are also used on the Volt.

As a result of the aero enhancements, aerodynamic drag was reduced by 10 percent over a non-Eco model, with a coefficient of drag of 0.298. That places Cruze at the top of the class for mainstream compact cars.
