2008 Pontiac G6 review: Our expert's take

Vehicle Overview
Pontiac introduced the sporty midsize front-wheel-drive G6 sedan for 2005, aiming it at the Mazda6, Mitsubishi Galant and Nissan Altima. Coupe and retractable-hardtop convertible body styles joined the lineup for 2006. For 2008, a GXP high-performance trim, available as a coupe or sedan, has been added to the lineup. It replaces the GTP model.

The G6 has multiple engine choices for 2008, including a 3.6-liter V-6 for GXP models. Exclusively teamed with this engine is a six-speed automatic transmission. Other changes for 2008 include newly standard seat-mounted side-impact airbags, standard antilock brakes and traction control on all models.

Exterior
Displaying a wedge-shaped profile, the G6 sedan has wraparound headlights and triangular wraparound taillamps. Built on a 112.3-inch wheelbase, each body style has short overhangs, measures 189 inches long overall and is 70.6 inches wide. Pontiac’s signature twin-port grille has chrome accents and mesh inserts. Pushed-forward A-pillars give the windshield a sharper rake. The coupe and retractable-hardtop convertible look similar to the sedan, but the doors are 6 inches longer and the rear ends differ.

The G6 uses a sport-tuned fully independent suspension with front and rear stabilizer bars. Three wheel sizes are available: standard 16-inchers for the base sedan, 17-inchers for GT models and 18-inchers for GXP editions. Three new colors are available, including Cranberry Metallic, Midnight Blue Metallic and White Diamond Tricoat.

GXP models receive redesigned front and rear faces with new rocker moldings, dual-exiting exhaust and polished stainless steel grille outlines. A Street Edition adds dual hood scoops and a unique rear spoiler to the GXP.

Interior
Like other Pontiac models, the G6 cockpit contains sporty controls and racing-style gauges with red LED backlighting. The coupe and retractable-hardtop models have seating for four, but the sedan can seat up to five. Brushed metal accents and chrome trim decorate the interior. A tilt/telescoping steering wheel is standard, and adjustable pedals are optional.

Due to its relatively long wheelbase, the G6 sedan promises abundant backseat legroom. The sedan’s trunk measures 14 cubic feet — the coupe’s and convertible’s are slightly smaller at 12 and 12.6 cubic feet, respectively, but the convertible’s drops to 2.2 cubic feet when the top is down.

Under the Hood
The base sedan holds a 164-horsepower, 2.4-liter four-cylinder, while GXP editions feature a 252-hp, 3.6-liter V-6. A 219-hp, 3.5-liter V-6 goes into GT models, and convertibles can be equipped with a 222-hp, 3.9-liter V-6. A four-speed automatic transmission is standard in base and GT models, and GXP models have a six-speed automatic.

Safety
All-disc antilock brakes and traction control are now standard on all models. An electronic stability system is optional on GT models and standard on GXP sedans and coupes. Side curtain and side-impact airbags are now standard in coupes and sedans.

Driving Impressions
With the 3.5-liter V-6 and automatic, the G6 sedan performs well enough, aided by mannerly automatic transmission operation. Though it’s an improvement over the Grand Am, the G6 isn’t a big step forward.

Handling is on the ordinary side, and substantial steering effort is required. The G6 is quiet and rides comfortably most of the time. Monsoon radio controls are confusing. Rear legroom in the sedan is good, but headroom is horrible.

I’m a bragging past owner of a 2006 G6 Gypsy sedan.

I’m a bragging past owner of a 2006 G6 Gypsy sedan. First owner up to around 37,000 miles. Great experience & performance! Only issue that aggravated me was the key release from the ignition “ which was repeatedly repaired & never solved?” My model was the rare 6 speed manual “ yes in a sedan!!!!” The manual had to be in a certain precise position to trigger the ignition key release. I joked with GM service department that apparently the car wanted to keep driving?! The only other service I can remember was the leather seat cover replaced because the color wore away. & a suspension part up front. Everything covered by factory no arguments. I’m extremely serious that this is one General Motors hidden past gems!!!! “ keep in mind I am NOT talking base entry level model here.” Everyone knows about the G8 the solstice which is understandably justified! However these G6 GTP & GXP are the best investment for the budget minded to get performance in a competitive fun driving sedan with luggage & storage space!” Unless you’re smart enough to purchase the HARDTOP metal roof convertible!” Do your self & your wallet a favor & don’t ignore the vehicle when looking!

DO NOT BUY NOT WORTH IT

i bought the car with 80,000 miles the second day of driving which was a 2.5 mile drive to my girlfriends the power steering rack and the pump blew up. i repaired it 4 times before the issue was resolved. Over 1,000 dollars each time also and then when i hit 100,000 miles it decided to leak out all of its oil an blow up my crankshaft to the point i poured oil in and it literally leaked all out immediately. STEER CLEAR OF THIS CAR.
