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.

2008 G6 GT Convertible 3.9

I found this car on a BMW dealership's used car lot in 2018. I fell in love with it at first site. The car was in immaculate condition and was priced fairly reasonably at $8,900.00. I just got my first VA disability check and was able to purchase it with no credit. I am always proud to drive this car. It is a hardtop convertible. It is sporty but not a sports car. It gets horrible gas mileage as I primarily do city driving and have averaged just about 15 mpg. But I own it now and KBB is supposedly just $2250.00. I don't think you'll find one in this condition (as of this writing Jan 21) for less than 8500. Rightly so because it is a hardtop convertible. At about 89,000 the tonneau cover covering the whole behind the headrests blew off and I continued operating the top for some time. This further damaged the top and mechanism forcing me to have to replace the whole assembly. Fortunately I found a dealer in Clearwater (Autonation Chevy) who was competent and did an outstanding job. So for $1,500.00 I repaired my top on my $2300.00 car and I love it again. Only problem is tire pressure warning system. I also had to replace the thermostat in the engine ($250.00) and bought new performance brakes and rotors on Amazon and had those installed total price $300.00. And I still love it. It is the prettiest car in my parking lot and I always get complements on it whenever I stop at Sams club for gas. It is quick enough but as all the original reviewers put it, it is a family car whose top can come down. It has stood up to at least 6 grueling Florida seasons three of them in front of my condo exposed to the elements and no problems. I currently have just shy of 94,000 miles on it and wouldn't dream of replacing it any time soon because anything else would cost three or four times as much for the same value. And I didn't mention the Monsoon sound system which is amazing. I use my phone with a bluetooth dongle and quite simply the sound system sounds better than any other car in 30 to 40 k price range (I have tried premium sound systems in the Hyundai Genesis and Kia products) , the Mustang and a few others and quite simply this machine has an amazing sound system. Even though the FM radio stopped working a year ago, Spotify and Sirius XM always rock and that Bluetooth dongle does the trick and notably most phones now have Dolby Atmos which works with the Bluetooth dongle so no reason to get a new car just so you can get an infotainment system which will be obsolete in three years. Only thing now is to upgrade the interior a bit and perhaps some touchup paint on the hood and rear deck lid - seeing as how I've had a mechanical carwash membership for the car for about 2 1/2 years and it has been washed every other day that entire time.... just goes to show how much I love this car.

Good ole boys selling good ole cars

I loved driving this car. Fast when I want and not a bad style either. The price is about right with my trade this will work out fine.

Great basic car

This car is very basic but is also just enough to stay happy with. Rides nice and has pretty comfortable seats. Had no issues with it at 115k miles. Went through 2 front end accidents with minimal damage
