2008 Pontiac G8 GT Review

The first time GM attempted to create a BMW 3-Series fighter, we got the Cadillac Cimarron. After 27 years of trying again (and again and again) to take on the rear-wheel drive driver's car, we've got a rebadged Australian import that goes by the name Pontiac G8. No question: the G8 is a far better automobile than the Cimarron (what modern car isn't?). But it's still no 3-Series. Frankly, it's not clear what it is.

The G8's bodysides couldn't be more purely E46 if they'd been penned in China. Sure, some hood fauxpenings were added at the eleventh hour to provide Pontiac "character." But look at this car a thousand times, and it still won't look like a Pontiac. The sides are too clean, the proportions too slender for Detroit iron. (Or post-Bangle BMW, for that matter.) And as with Chinese knock-offs, such a close copy can't hope to have its own identity.

x08pn_g8020.jpgMany enthusiasts pine for the days when BMW interiors were designed for driving, with solid if unflashy materials, minimalist lines and no gadgetry. Welcome to the cabin of the G8. Someone Down Under appears to have made it their personal mission to squeeze all of the power window, power lock and power mirror controls into a single compact module located on the center console. (As seen previously in the GTO, there's ergonomics, and then there's Aussie ergonomics.) As a result, the front door panels are button-free; you can't get cleaner than that.

x08pn_g8017.jpgOne thing GM didn't copy: the dimensions of an E46. People who've seen the G8 only in photos often think it's the size of a 3-Series, or perhaps a 5-Series. In fact, the G8 falls closest to the regular wheelbase 7. For GM, bigger has always equaled better. What better way to improve on the 3-Series than to add 20 inches of length and a half-foot of width?

Of course, for buyers seeking a roomy sedan the space will be welcome. The comfortably high rear seat cushion can easily transport three adults, and the trunk can swallow everyone's luggage. The entire rear seat does not fold, but the center pass-through provides a larger opening than some folding seats.

When behind the wheel, a relatively high seating position and a driver-oriented design helps the largest Pontiac feel smaller than it is. It doesn't feel like a 3, but it doesn't feel like a Dodge Charger, either. A 5 perhaps. Even some of the world's thickest A-pillars (no room in the budget for high-strength steel?) don't ruin the pistonhead party.

x08pn_g8019.jpgThe G8 GT's rear-drive chassis feels nearly as balanced as a BMW's. The rear end can be smoothly throttle-steered through turns–without the standard stability control killing the joy. There's more kickback through the steering than desirable road feel, but at least there's road feel– something that can be said of fewer and fewer cars in the post-Lexus age. Body control is tight and precise, with very little in the way of ungainly slop.

With such a firm standard suspension, ride comfort isn't a G8 strength, even with the 18-inch tires (even less compliant nineteens are optional). Think 3, with the Sport Package. Hardcore enthusiasts won't mind feeling every bump. But the rest of the driving population? Sell this one to Avis, and renters will complain. Apparently GM has (finally) bought its own hype, and created a Pontiac suitable only for enthusiasts.

If there's anything American about the G8, it's the GT's 361-horsepower 6.0-liter V8. Except this one is more refined than the typical American pushrod V8. This refinement cuts both ways. You won't mistake the L76 for a high-winding DOHC unit, but it doesn't seem out of place in such an otherwise European car. The downside? While the G8 GT is undeniably quick when you plant your right foot, you have to rely on the rapidly rotating needle for this info. It would feel quicker with a more visceral powerplant.

If only the six-speed automatic was a willing partner; it often resists downshifting. The best slushboxes smoothly select the optimal ratio before the driver is aware that he's called for a new gear. This isn't one of those cog swappers.

Aside from making a car larger, GM can also be counted on to make it cheaper. In this case, you get a 7-sized 5-handling 3-looking 361-horsepower sedan for the price of a 1, and a 128i at that.

x08pn_g8023.jpgWhile not clearly a Pontiac, the G8 is clearly a bargain for anyone who's been seeking a super-sized, pushrod-powered, two-ton 3-Series. Unless the 15/24 on the window sticker scares even this crowd, GM will sell all it cares to lose money on. (The Australian dollar near parity with the greenback? Gotta hurt.) With a clearer identity, less spartan interior and more compliant suspension, there'd be less need to rely– in traditional GM fashion–on a low price.

  • B.C. :


    Hell must be freezing over — I want one, and I’m a hardcore Honda fanboy. Make mine a 6-speed manual GXP in cop-magnet-red, please.

  • BlindOne :


    Too bad they aren’t bringing the car over with a manual this year. Still, the first GM I’ve seen in years that makes me go ‘Hmmmm’ Still think I’ll buy a G35S Sedan, 30 less horses, but Infiniti.

  • Detroit-X :


    I’m really glad to see this car from GM. Nice looks, great performance, low price, unique in a crowd. Too bad about the lack of profits, though.

  • Oldsmoboi :


    Why must every f-ing car be compared to the 3-series? What’s next, comparing the Lacrosse Super to the 3-series? They are completely different target markets. This is NOT a 3-series competitor in anything other than price. It’s a Bonneville replacement with real performance cred. It’s a replacement for the RWD Impala SS with actual handling built right in. But above all it is NOT a 3-series competitor any more than the Lacrosse Super, Bonneville GXP, or Mercury Marauder are.

  • thalter :


    You mention power window controls twice in the center console. I think you meant “power windows and power mirrors” instead.

    My bad. Text amended.

  • RayH :


    I’ll take your word on the balance being close to BMW… that was my biggest fear for this car. I think those who never let go of their pre-03 5 series because they still hate the look of the 5 might take this as a stopgap until the next 5 series. Not everyone buys a BMW for the badge, at least 5 series buyers. Lack of manual hurts.

  • John R :


    I’m going to have to agree with initially comparing this car to the 3-series. GM has clearly positioned this car against a BMW, the 5-series.

    Rightfully so, I think. I would have never considered spending my money on a Pontiac…until today.

  • SupaMan :


    The G8 is compared to the 3 Series because in many reviews and enthusiasts’ eyes, the BMW epitomize the essense of what a proper sports should act and perform. BMWs, even the uber 7 Series, are generally praised for their sportiness and fluid performance on the track. However, I don’t think people will be cross-shopping the G8 with the 3, or even the 5 Series…more with the Charger.

    Thanks for the review Michael. Very well done. Keep up the good work.
