KBB Editor's Overview

By Editorial Staff

The 2008 G6 Coupe plays a key role in both Pontiac's and GM's recovery efforts, representing a powerful example of how Pontiac's design philosophy once again aims to lure back driving enthusiasts. Forget the plastic-clad Grand Ams of the past; this coupe is sleek, sophisticated and built for driving. Available in two trims (the sportier being the new GXP), the G6 targets import buyers who want a bit more flair but don't want to break the budget. While not up to the overall standards set by the Honda Accord, the G6 Coupe definitely presents strong competition for the Mitsubishi Eclipse, Ford Mustang V6 and Hyundai Tiburon.


You'll Like This Car If...

If you're in the market for an affordable front-wheel-drive sport coupe with a racy look, seating for four and a modest price tag, the 2008 Pontiac G6 may make your day.

You May Not Like This Car If...

If you're seeking a GT or GXP with a manual transmission, you'll be out of luck. The G6's interior plastics are not as refined as those found in the Honda Accord, and there is no four-cylinder engine option.

What's New for 2008

The GTP trim is replaced by the all-new GXP, which features a unique front end, performance suspension and a 252-horsepower 3.6-liter V6 engine. XM Satellite Radio, front seat side-impact airbags and OnStar are made standard on all G6 coupes.

Driving It

Driving Impressions

The GT's base 3.5-liter engine doesn't inspire performance driving, but it is adequate for quick jaunts up freeway entrance ramps and around town trips and commutes. We wish a six-speed manual were available with the GXP model, as its 3.6-liter V6 is both spirited and refined. As it is, GXP drivers will have to settle for the six-speed automatic, which does a good job finding the correct shift points, but leaves the driver feeling somewhat disconnected from the process. Both the GT and GXP trims use a hydraulic power steering unit that returns good feedback and on-center feel. The G6's sport suspension strikes a pleasant balance between performance and comfort, although some hardcore enthusiasts might prefer that balance to be more toward performance.

The newest GM V6 is thoroughly modern and long overdue. Smooth, quiet and powerful, the 3.6-liter engine wants only for a nice manual transmission.

Vehicle Details


The G6 interior is a bit of a mixed bag. We applaud the clean design, excellent seats and generous legroom. The plastics used on the dash, console and door, however, have a heavy, hard feel and the chrome trim rings surrounding the instruments seem a bit trendy and overdone. Controls are placed within easy reach and we welcome the optional steering-wheel mounted switches for the audio system. The instrument panel's orange backlighting and large, legible numbers and letters make night driving easier on the eyes. Tall passengers occupying the rear seats may find that the raked rear window limits headroom.


Compared to previous Pontiac coupes, the G6 is a breath of fresh air. Its sporty sheetmetal is devoid of tacked-on plastics and garish add-ons, relying on strong design elements and a fastback-like rear window to convey its personality. The familiar Pontiac split grille and swept-back headlamp lenses remain in place, as do the numerous red arrowhead badges. On the new GXP trims the exaggerated split grille is drawn down below the bumper to create a sinister look befitting the car's new-found performance potential. With its wheels pushed to the outer edges, the G6 appears longer than it actually is; this approach also reduces front and rear overhangs---an important design element that allows for better maneuverability.

Notable Standard Equipment

The GT trim includes a 3.5-liter V6, four-speed automatic transmission, traction control, single-disc CD player, air conditioning, power windows, power mirrors, remote keyless entry, cruise control, anti-lock disc brakes (ABS), 17-inch alloy wheels, Monsoon sound system, tilt/telescopic steering wheel, front seat side-impact airbags, head-curtain airbags, OnStar with Turn-by-Turn navigation, four-way power driver's seat, leather-wrapped steering wheel and a sport-tuned suspension. The GXP adds the 3.6-liter V6, a six-speed automatic transmission, 18-inch alloy wheels, StabiliTrak stability control, body-colored power mirrors, automatic climate control, heated seats and a six-way power driver's seat.

Notable Optional Equipment

Options for the G6 GT include StabiliTrak electronic stability control, six-way power driver's seat and heated leather seats. GT and GXP options include a power sunroof, six-disc CD/MP3 changer, power-adjustable pedals and remote engine start.

Under the Hood

The 3.5-liter pushrod V6 provides adequate power but lacks a sense of urgency. If you're purchasing the G6 to perform, you should opt for the GXP, which includes the refined 3.6-liter V6. This engine delivers the power and quietness expected in this price range, along with good fuel economy.

3.5-liter V6
219 horsepower @ 5900 rpm
219 lb.-ft. of torque @ 3200 rpm
EPA city/highway fuel economy: 17/26

3.6-liter V6

EPA city/highway fuel economy: 17/26


Pricing Notes

The G6 GT Coupe's Manufacturer's Suggested Retail Price (MSRP) starts around $23,000, while the GXP stickers for just over $26,500. Equip a GXP with every possible option and the price tops out around $30,000. It's often difficult to know just where to begin when negotiating price, so be sure to check the Fair Purchase Price beforehand, as it shows the typical transaction price being paid for a G6 in your area. Also be sure to check the Incentives tab to see what further savings might be offered by the manufacturer. As for resale, the G6 holds up much better than previous Pontiac coupes, retaining acceptable five-year residuals just behind those of the Ford Mustang V6, Mitsubishi Eclipse and Hyundai Tiburon.
