General Motors (GM) on Thursday launched a fully redesigned version of the Chevrolet Aveo sedan just 2.5 years after its debut. The new Aveo features an all-new exterior and roomy interior design, but fuel economy compared to the 2006 model is just incrementally better.
The 2007 Aveo sedan is longer, wider and taller than its predecessor. Contributing to Aveo sedan’s more aerodynamic design is the incorporation of the radio antenna into the rear glass. Extensive wind tunnel testing also helped reduce the coefficient of drag from 0.348 to 0.326, compared to the previous model.
The 2007 Aveo uses the same E-TEC II 1.6-liter four-cylinder DOHC/16-valve engine with variable-geometry intake as in the 2006 model, and offers 103 horsepower (77 kw) at 6,000 rpm and 107 lb-ft (145 Nm) of torque. The engine is enhanced by an electronic throttle control, added in the 2006 model year, and variable geometry induction system, which help maximize power across the rpm range. Electronic throttle control enhances driveability and fuel economy, while reducing emissions. The Aveo 2007 carries a ULEV II emissions rating.
The engine’s variable geometry induction system is designed with a longer runner length at slower speeds to increase low-end torque up to 10%. The system includes a bypass valve that is activated in high rpm or heavy throttle applications.
|Comparative EPA Fuel Economy (mpg US)|
A five-speed manual transmission is standard. The available Aisin four-speed automatic transmission features adaptive shift technology.
Estimated fuel economy rating for the new Aveo is 26 mpg city, 34 mpg highway for the four-speed automatic and 27 mpg city, 35 mpg highway for the five-speed manual. The 2006 Aveo carries an actual EPA rating of 24 mpg/34 mpg for the automatic and 26 mpg/35 mpg for the manual.
Those figures are lower than those of the Aveo’s new competition, the Toyota Yaris and the Honda Fit. (See chart at right.) Both the Yaris and Fit use 1.5-liter engines.
For calendar year 2006 through the end of July, Chevrolet sold 35,078 units of the older Aveo, a drop of 16.1% from the 41,795 units for the same period in 2005. By contrast, Toyota has sold 32,822 units of the new Yaris, which went on sale in March. Honda has sold 15,922 units of the Fit, which went on sale in April.
The Aveo, sourced from GM Daewoo, is a global car for GM. In 2005, 68,085 Aveos were sold in the United States, and the car will be offered in more than 120 countries under different nameplates.
