Chevrolet Cruze optimized the Eco’s aerodynamics
>> Thursday, November 24, 2011
Chevrolet Cruze 1.8 LT optimized the Eco’s aerodynamics by inconspicuously paneling off more of the upper grille than on other Cruze models and by adding motorized shutters to the lower air intake to close it off during high-speed cruising. Chevy also lowered the Eco 0.4 inch with springs borrowed from the Cruze’s optional sport suspension and smoothed airflow beneath the car with underbody panels. Finally, engineers fitted a thin spoiler to the trunk and installed a full-width air dam beneath the front fascia. The net result is a claimed 10-percent drop in aerodynamic drag, and the lower stance means less body roll in corners—not to mention a sportier look.
Eco Optimization
Like many economy-optimizing trim packages, the Eco uses low-rolling-resistance tires (Goodyear Assurance) and lighter wheels to help meet its goals. Unlike most of its competitors, though, the Eco has a higher (mileage) calling from the moment it starts down the assembly line. With weight saving a priority, it is constructed differently than the regular Cruze, using slightly shorter welds and thinner sheetmetal in specific areas. The lighter Goodyears and the stylish 17-inch wheels combine for a saving of more than 21 pounds compared with the 16-inch combo on the Cruze 1LT. Factor in a fuel tank that is smaller by three gallons and the lack of a spare tire on manual-equipped cars, and the Eco weighs in at 3018 pounds, between 125 and 188 fewer pounds than other Cruzes we’ve tested.
