Replacing the Sunfire in the Pontiac lineup, the G5 is the company’s entry-level offering and is only available as a coupe. The G5 combines a sleek design with a powerful, fuel-efficient drivetrain to provide a fun driving experience starting under $17,000. Adding a sportier look, the G5 GT adds reshaped front and rear fascias, 17-inch alloy wheels and a decklid spoiler. The Pontiac G5 comes with a five-year/100,000-mile powertrain warranty and gets an estimated 32-37 mpg on the highway.
