The 2010 Pontiac G6 remains essentially unchanged after a significant re-working for 2009. Offered in front-wheel drive only, the 2010 G6 is available as a coupe, hardtop convertible, or family sedan. The coupe and sedan are offered in base, GXP, and, in the case of the sedan, Value Leader trims, while the hardtop convertible is delivered as the G6 Convertible GT. The 2010 G6 is a five-passenger compact, and all trims except the Value Leader are available with a number of drivetrain configurations.

The base engine for the 2010 Pontiac G6 is an E85-compatible Flex Fuel 2.4-liter inline four cylinder (I4) with a four-speed automatic transmission, which puts out 170 hp and 158 lb-ft of torque. EPA estimates for the I4 are a highly respectable 22/33 mpg. The 2.4-liter I4 and four-speed automatic are standard in the base G6 coupe, base G6 sedan, and G6 Value Leader sedan, with a six-speed auto-manual tranny available for each trim except, of course, the Value Leader. A 3.5-liter Flex Fuel V6, capable of 219 hp and 219 lb-ft of torque with its standard four-speed auto-manual transmission, is also available for both the base 2010 G6 sedan and coupe trims, and standard for the Convertible GT. Next, Pontiac offers a 3.6-liter VVT V6 engine and six-speed automatic, good for 252 hp and 251 lb-ft of torque, in both the 2010 G6 sedan and coupe, turning each into a GXP trim. EPA estimates for the GXP trims are 17/26. Finally, Pontiac also offers a 3.9-liter V6 engine, putting out 222 hp and 238 lb-ft of torque, with the G6 Convertible GT. A standard four-speed auto-manual transmission manages the 3.9-liter V6.

Standard appearance, comfort, and convenience features for the 2010 Pontiac G6 Value Leader sedan include 17-inch steel wheels, cloth front bucket seats, power windows, door locks, and mirrors, air conditioning, a single-CD player with six speakers, Sirius/XM satellite radio, and Onstar hands-free communications technology. The base G6 sedan and coupe trims, though equipped identically with the Value Leader, add such options as engine upgrades, 18-inch chrome-clad aluminum wheels, leather, chrome accents, cruise control, remote start, a power-tilt sunroof, and a premium audio system. The 2010 Pontiac GXP sedan and coupe trims offer such additional standard amenities as a 200-watt, eight-speaker Monsoon audio system, cruise control, chrome-tipped exhausts, and an eight-way power adjustable driver’s seat, as well as leather upholstery and appointments. The 2010 Pontiac G6 Convertible GT is delivered with standard features that include 18-inch alloy wheels, a two-way adjustable power driver’s seat, and the popular power up/down hardtop convertible roof with a glass rear window.

For 2010, the Pontiac G6 offers such standard safety features as four-wheel ABS, traction and stability control, front side-mounted airbags, front and rear head curtain airbags, a remote anti-theft alarm, and front fog/driving lights.

The 2009 Pontiac G6 drew complaints from owners regarding poor fuel economy with its larger V6 engines, as well as chintzy interior materials, uncomfortable seats, lack of a manual transmission, and its small trunk (nonexistent on the Convertible GT with the top down). Style, roominess, ride, the hardtop-convertible configuration, and performance, however, drew plaudits from virtually all 2009 Pontiac G6 owners. The 2.4-liter I4 was singled out by many owners as an especially economical powerplant.
