Providing power to the 2009 Pontiac G3's front wheels is GM's fuel-efficient 1.6L Ecotec four-cylinder producing 106 hp at 6400 rpm and 106 lb-ft of torque at 3800 rpm. What the G3 may lack in power, it makes up for in EPA mileage ratings. When mated to the standard five-speed manual, the Ecotec gets 27 mpg in the city and 34 mpg during highway runs. Buyers opting for the available four-speed automatic will achieve around 25 mpg city and 34 mpg highway. Surprisingly, despite its small size and miserly engine, the G3 won't be the most frugal Pontiac on the highways when it arrives in Pontiac showrooms next spring. Pontiac lists the base G5 coupe at 37 mpg highway.
The G3 differentiates itself from its Chevrolet Aveo relative through a slightly reworked front clip featuring the Pontiac trademark dual grille. A smaller, G8-inspired front bumper and foglights are fitted below the Pontiac emblem. Incorporated into the G3's hood and quarter panel fenders are rear sweeping, wraparound headlights. Not surprisingly, the sides and rear of the car as well as the standard spoiler above its back window are identical to those on the Chevrolet variant.
