Chevrolet has given the Korea-built 2007 Aveo an update in the face of stiff new competition from Japan. Inside and out the styling has been upgraded for a more substantial look and feel. Under the hood, the 2007 Chevrolet Aveo sedan contains a 103-horsepower four-cylinder engine that drives the front wheels through a five-speed manual transmission. Chevrolet says this powertrain can get 35 mpg on the highway. A four-speed automatic is optional for folks who can’t, or don’t, row their own gears. Power steering is standard, and antilock brakes are optional. On the safety front, Chevrolet installs dual-stage front airbags and side-impact airbags, but there are no side-curtain airbags like in the competition. Nevertheless, Chevrolet claims that the 2007 Aveo will achieve five-star safety ratings during impacts with vehicles of similar size and weight based on NHTSA frontal crash-test scores for the structurally-identical 2006 model.
