2008 Pontiac G8

    MAP = ERMA...= GREED. Just like the oil Market. Not one segment, the entire market. ALl other prices follow.

    As I have said, when it is time for me to replace mt current ride, I do not pay Extra Money to the dealer. It ain't that good!

    According to the latest 2009 information
    I have seen - from GMFleet:

    • Bluetooth connectivity for cell phones available (late availability)

    I believe GM Supplier discount is up to the dealer to be honored...its not required.......remember dealers are independent franchises these days.....not corporate owned.....depends on how bad they want your business...

    So no manual trans for 09? Or will you have to buy the GXP for that? I haven't seen one in person but it does look nice.
  • paisanpaisan Posts: 21,181
    I believe that GXP is going to be the only way to get it in an MT.

    It's a 4,000lb car, so having a manual isn't going to really make a difference as the car is far from trackable at that weight.

  • dialm4speeddialm4speed Posts: 110
    Not really worried about track action. I don't care too much for those auto/manual trannies. I prefer one or the other.
  • paisanpaisan Posts: 21,181
    They are just automatics, that you can choose what gear you want. They aren't DSG style transmissions, there is a torque converter in there.

    The G8 is a great car for the money, without a doubt. I'd love to have one. But a BMW or Mecedes it ain't.

    "It's not supposed to.... many are not looking for an emblem to fulfill their ego or give therapy to their insecurities. Raw performance and decent comfort features that gives a Bimmer a good spanking and run for it's money."

    Not everyone buys a BMW for image/ego. Things like superior build quality/fit and finish, quality of materials (leather and walnut vs plastic), steering feel, sublime suspension tuning - and don't forget the ability to oder a MANUAL transmission - matter to some people more than the emblem. Albeit well-heeled people, which I'm not, but I can still apreciate the differences. The G8 comes up short in the area of comfort features as well. A hard to reach and turn knob to adjust seatback angle??? Come on, you can probably get Cobalts and Focuses (Focii?) with power seatbacks. No nav or Satellite radio option? They don't interest me, but they do seem to matter to a lot of folks. As for the ummm, "spanking", lets look at the "Raw performance" numbers, as tested by R&T:

    550i G8

    0-60 5.0 5.0 (5.3 Car & Driver)
    0-100 12.1 12.3
    1/4 mi 13.5@105 13.5@104.9 (13.8@104 Car & Driver)
    Top Speed 150 mph 140 mph
    Lat. Accel .92g .85g
    Slalom 65.3 mph 64.3 mph

    Like I said, well-heeled, I ain't. But if someone were to give me my choice, paid-for, it wouldn't even be close. Actually, I'd probably go for a 335i, 6 speed manual, no nav, etc. The price difference would be much smaller, and I'd have a lighter car with even better handling and performance numbers, and better fuel economy, too.
  • white6white6 Posts: 588
    I agree with everything you said... I currently drive a 335i.

    However, you say: "Actually, I'd probably go for a 335i, 6 speed manual, no nav, etc. The price difference would be much smaller, and I'd have a lighter car with even better handling and performance numbers, and better fuel economy, too."

    You would also have a much smaller vehicle. G8 is a full-sized car; 335i is a compact car.

    You would also have a much smaller vehicle. G8 is a full-sized car; 335i is a compact car.

    See the bit about handling and performance. And with gas already over $4/gallon for premium, and still heading north, the extra 4 or 5 mpg could make a difference as well.

    The performance figures I quoted didn't format well to the forum, so here's a second try, formatted differently:


    0-60 - 5.0
    0-100 - 12.1
    1/4 mi - 13.5 @ 105 mph
    Top Speed 150 mph
    Lat. Accel .92g
    Slalom 65.3 mph


    0-60 - 5.0 (5.3 Car & Driver)
    0-100 - 12.3 (12.7 Car & Driver)
    1/4 mi - 13.5 @ 104.9 (13.8 @ 104 Car & Driver)
    Top Speed - 140 mph
    Lat. Accel - .85g
    Slalom - 64.3 mph

    FWIW: 2008 EPA mileage rating comparison

    BMW 335i w/steptronic: 18 city/26 highway/21 composite

    Pontiac G8: 15 city/24 highway/18 composite

    Keep in mind, too, that the G8 will run fine on 87; BMW requires minimum 91 octane. I calculated a cost comparison and, using the composite numbers and regular/premium price difference, the G8 would be about 10% more per mile for gas. I usually get around 25 mpg in my 335i, but it's mostly rural/interstate highway driving. I doubt I could match that in a G8 GT. But the 335i is also much more cramped inside; you're obviously trading space for efficiency here (among other things).

    imo, the cache of the 3 series has long worn out...just too many around. now the g8 gt on the other hand...i have yet to see one on the road, and by most accounts, it's a damn fine car! with my limited resources...a g8 gt will work exceedingly well, even if it doesn't quite rate up there (objectively or subjectively) with a bmw.
  • paisanpaisan Posts: 21,181
    Are we forgetting the 1998-2005ish 3 and 5 series that had poor electronics and diodes in their dash panels?

    As we've all been saying the G8 is not a BMW, however, for $30k you can't get close in terms of SIZE + PERFORMANCE from anything from BMW.

  • wideglidewideglide Posts: 146
    imo, the cache of the 3 series has long worn out...just too many around.

    Cache, schmache. I would love to have one because they are the best performing and handling 4 seat car on Earth under $50k. Unfortunately, by budget is missing quite a few of those "K's".... :(
  • circlewcirclew Posts: 8,416
    The one I lease has me spoiled. The base G8 is a houseboat in the suspension department (and roominess) compared to the 330. I will test the GT when my dealer is allowed to get one again!

  • bigelmbigelm Posts: 995
    There are so many things wrong with your comparisons of the G8 vs. 330; it's not even the same size for cryin' out loud. Compare it where it should be, 535/550; the G8 already beats it in roominess - which I desperately need. Comparing it to the 330 is a waste of time. I have considered the CTS 3.6L 6MT, but if I can get more space and performance for my dollar, guess where I'm going? Under the radar is the Hyundai Genesis... I'm waiting for it to show up so I can make my decision!
  • circlewcirclew Posts: 8,416
    I know it's not an apples to apples but the difference in handling is huge. I compare what I consider for my next ride against old. The base G8 is out. On to the GT.

  • white6white6 Posts: 588
    You realize that the base and GT suspension is identical. Only difference is if you buy the sport package that upgrades to 19-inch rubber.

    BTW, if you check interior dimensions, the G8 is actually very close to 7-series BMW.
  • circlewcirclew Posts: 8,416
    The 19" rubber does nothing to help handling IMHO. GT interior looks bigger than the 7-series to me. This is a great performance family sedan but a curve-carver it ain't.

    There are just so many more opportunities to have fun with a serious sports suspension.

  • white6white6 Posts: 588
    I understand what you're saying. Based on everything I've read, they considered a "base" suspension that was softer and a optional "sport" suspension that would upgrade to what they, in the end, made the standard suspension, which I believe is the mid-level Holden-spec suspension. The Commodore SS-V, I believe, has stiffer suspension specs than what we got on the G8. Let's face it, everything's a compromise. I think that, based on my test drive, they did a pretty good job. You can't make all the people happy all the time...
  • rayainswrayainsw Posts: 2,608
    As stated, one can certainly compare anything to anything.

    But a comparison in handling between a G8 GT at near 4,000 lbs. and a BMW 330 ( or 335 ) really strikes me as grossly unfair. Would you think it fair to compare a BMW 335 to a 535 - or to a 750? To me, the size, weight & cost differences here make these comparisons ‘unfair’, at best.

    Comparing current to new ( potential ) ride makes perfect sense.

    I do the same.

    Yet, in my case as well, comparing my current C6 Corvette to a G8 GT is also exceedingly unfair to the G8. I need to incorporate a rather large accommodation in my comparisons - to account fo rthe G8 GT’s size, weight & cost.

    It looks like a 330 weighs something like 3500 pounds.

    My Corvette Coupe weighs barely over 3200. And cost me over $45K.

    Given such substantial weight disparity, my 2 test drives of G8 GTs ( both with Sport Package = 19” wheels & tires ) suggest strongly to me that the G8 GT offers a very competent package of handling & ride – for the weight & capacity ( in people & luggage \ ‘things’ ). And the various published reports also indicate that the G8 GT’s suspension is quite capable.

    The R&T test, in particular, might be of most interest here, as they tested a G8 GT without the Sport Package.

    “In normal or even fairly spirited driving, once again we had nothing but positive comments about the way the G8 GT's chassis performed, especially its silky, smooth ride with just the right touch of firmness. "The suspension is set up for an excellent balance of on-road comfort, smooth enough for pleasant daily driving yet firm enough for good grip in fast cornering," said Bryant. . . a solid handler up to around the 7/10ths mark”

    Personally, I do not exceed ( approx. ) 7 tenths in my street driving. For several reasons. And how it handles under those conditions is by far most important to me.

    Thus, I leave the establishment of the absolute handling limits to those with access to a “closed course” – and the opportunity to drive without a Sales Associate in the right front seat.

    My test drives are more designed to see how seats & control position suit ME. To see how handling, in enthusiastic driving - but well below the car’s limits, FEELS to ME. And what kind of visibility ( one issue I had with the Corvette ) in all directions I have with the seat adjusted FOR ME. How the automatic (mis)behaves in MY style of driving. Etc.

    [[ The 335i’s STEPTRONIC, for example, ( a wonderful device, in many ways ) does several things I do NOT like. ]]

    If you want & can afford & are happy with the size of a 335i, as I have posted multiple times, I certainly have no problem with you ( or anyone ) choosing that as their next car. If that is your ‘benchmark’ – and fits your budget, regarding handling, ride & acceleration, etc. – well, I’d be pretty amazed if what a G8 GT offers will really even interest you . . .

    But I could be wrong.

    - Ray

    G8 GT 4 ME – but I could probably also be happy with many aspects of a 335i – and a [ substantially ] lighter wallet . . .

    Note: Even a BMW 328 Sedan ( clearly, no match in acceleration for the G8 GT – as well as interior size ) with Sport Package, Premium Package & Automatic ( STEPTRONIC ) lists for over $39K.
  • circlewcirclew Posts: 8,416
    First, my 330xi weighs 3,800 lbs. and even a 5'er is around that weight. I can honestly say the handling with my stock non-sport suspension as well as steering feel vs. the G8 (considering that 200 lb variance in weight) goes to the 330 at the end of the day. The steering feel and precision is lacking in the G8.

    Fairness is in the eyes of the purchaser so for me, the cost savings vs. the differences will be my consideration. As you say, it costs for the additional performance.

    After 35K miles in the 3'er, the overall balance is hard to beat but I will still test the GT anyway. Benchmarks are used to consider the other factors in any trade-offs. The $$$$ difference does interest me in a GT option. My car listed at $42K in '06.

    The G8 is still the best I've driven in sedan cloths from GM in a long, long time. Add the V-8 and it is very tempting...without MAP, which I would not intend to spend.

  • rayainswrayainsw Posts: 2,608
    Edmunds ( and a couple of other sources ) say the 2006 330xi weighs 3483:

    Here's from Edmunds..3,627. I stand corrected. I also average 22mpg tank to tank.

    The 335xi is 3,814 lb. curb weight.

    So, at 3,995 lbs., the GT is 381 lbs. heavier than the 335xi and 367 lbs. more than my car. That'll make up for most of the handling differences outside of steering feel and precision.

  • rayainswrayainsw Posts: 2,608
    Looks like ( although there is '2006' in the link I posted )
    the link actually points to a 2005.
    Anyway - a 2006 330xi, w/the HP bump apparently also
    weighs a bit more...
  • circlewcirclew Posts: 8,416
    Yes, and the 335i gained weight in 2 years! Anyway, the point I was making was a personal preference after the short time I was with the G8 base. Price is a huge factor in the mix that I need to consider. The GT makes that issue a very clear factor in it's favor vs. another BMW 3. 6 months left for decision time.

  • I have the 535i as 3660lbs. So its still lighter than the G8.

    You could do a similar comparo of the G8 vs 535 as the G8 vs 335. The result is similar, but the 'compact' argument goes away. The 535 is not a small car, and it certainly has handling down.
  • rjlaerorjlaero Posts: 659
    I just saw a brilliant red G8 on the road today and it made my head, what a great looking car.

    I think it looks nicer than any current "bangleized" BMW from the past 1/2 decade.

    You're comparing wrong brands. But Pontiac is marketing this car as a poor mans 5 series, though, so they're stirring the pot. From the reviews I've read, it comes as close and they ever have before.

    Only down side is that it's the wrong time to be marketing gas guzzling 6.0 engines that get 15 mpg in the city.
  • circlewcirclew Posts: 8,416
    Even the 5'er gets better gas mileage....but that's not what it's about. It's about the performance/$ equation.

    BTW, the service at BPG vs. BMW is no comparison. If the car is in for repair, I get an equal or better ride every time. That is part of what you pay for.

  • rayainswrayainsw Posts: 2,608
    The 535i is EPA rated at 2 MPG better \ higher than a G8 GT.
    ( Again, the more comparable 550i is worse than the G8 GT. )

    By my calculations:
    In 15,000 miles per year
    At $4.00 per gallon
    That is a saving of less than $200 / year.
    Less than $5.00 per week.
    Less than $600 over 3 years . . .

    Is that really going to be deemed significant when looking at thousands difference in transaction price on the 2 vehicles?
    [[ Rhetorical question, that. ]]

    Regarding the caliber of service loaner – OK. But, assuming I have no more \ no longer “service visits” with a G8 GT than my last 2 GM vehicles, a G6 would be fine with me. I do not expect an equal or better loaner when I bring in my Corvette.
