The high-output engine is rated at 169 horsepower (126 kW)* and delivers excellent fuel economy. It's connected to the smooth-shifting Hydra-Matic 4T45 four-speed electronically controlled automatic transmission. And because the powertrain is installed in the same robust chassis as all other G6 models - which includes the class-leading 112.3-inch wheelbase - the four-cylinder sedan offers razor-sharp handling and the smooth ride expected of a larger sedan.

2007 GT models feature a standard 3.5-liter V-6 rated at 224 horsepower (167 kW),* which is matched with a standard four-speed automatic with manual shift control. GTs also feature an optional 3.9-liter V-6 rated at 240 horsepower (179 kW) and 241 lb.-ft. of torque (327Nm) that is mated to a six-speed manual transmission.

2007 Pontiac GTP performance sedan and coupe are powered by a 252 horsepower (188 kW), 3.6-liter V-6 with variable valve timing that is mated to an advanced six-speed automatic transmission.

The chassis of all 2007 G6 models are tuned to complement their respective powertrains with responsive handling. All models use a MacPherson strut front suspension, with aluminum lower control arms and a direct-acting stabilizer bar. Suspension components mount to a U-shaped hydroformed chassis cradle. Rubber mounts isolate the body from the chassis cradle to minimize noise, vibration and harshness.

Out back, a four-link independent suspension design uses twin-tube shock absorbers and another direct acting stabilizer bar, all intended to minimize body roll during cornering. High-performance braking is an integral part of Pontiac G6's sporty nature. Large, heavy-duty four-wheel disc brakes provide excellent stopping power and great fade resistance. Front discs are vented and the rear ones are solid. Four-channel ABS and traction control are standard.

Sixteen-inch steel wheels are standard on the 1SV value-leader four-cylinder G6 model, while other four-cylinder and six-cylinder sedans offer available 16-inch cast aluminum painted wheels (17-inch cast aluminum painted wheels are standard on GT sedan and coupe; 17-inch cast aluminum Chrome Tech wheels are available). 2007 Pontiac G6 GT convertible and all Pontiac G6 GTP models receive standard 18-inch aluminum alloy painted flangeless five-spoke wheels.

2007 Pontiac G6 - Safe and solid

2007 Pontiac G6 features safety cage construction that is complemented with reinforced rocker sections, reinforced front body hinge pillar and roof pillars that were designed to improve impact protection. A magnesium cross-car beam unites the lower sections of the A-pillars. It helps protect passengers in side-impact crashes and also serves as the foundation of the instrument panel. High-strength steel was used in strategic areas to augment overall structural integrity.
