    Is There Any Way to Lighten a G8?

    I like the G8 a lot, but it's such a porky. Other than removing the interior (which I won't do) and the spare tire (obviously), are there any other ways to bring the thing's weight down? Something I didn't understand about the G8 and my GTO are that they weigh more than an Avalon, which is a much bigger car.

    Removing the spare tire wont help - they don't have one. Just an inflation kit.

    Why do you want to bring the weight down ? Are you worried about fuel consumption or performance ?

    Ummm... is your sentence correct? I don't get it... you're surpised that the larger Avalon is heavier than the smaller G8 and GTO? Isn't that logical?

    He probably meant "...more than an Avalon" but the Avalon is a FWD non-performance car so it isn't comparable. I think a better comparison would be the 550i.

    Re: Is There Any Way to Lighten a G8?

    Yes, I messed up on my grammar. I have corrected it. I guess since it's FWD it saves weight, but it's still a much bigger car and I don't think a driveshaft weighs 400 lbs.

    I want to bring the weight down, because of both reasons listed: fuel consumption and performance. I don't know why, but I like the G8 a lot. It's just that it's so heavy that keeps me away. I wish they used more lightweight materials... but then it wouldn't be the "most powerful sedan under $30,000." *Sighs.*

    Is Avalon really "a much bigger car"

    G8 / Avalon
    196.1 .. 197.2 (length)
    74.8 .. 72.8 (width)
    57.7 .. 58.5 (height)

    A much closer comparison might be G8 vs. Charger and 300C ......also RWD V8's.

    Back in the early 60's Pontiac modified the Catalinas for racing by adding aluminum bumpers and drilling holes in the frames to lighten them up. They were known as the Swiss Cheese Catalinas, so start cutting that car up....lol

    have you even driven a G8? with the power and handling that they have, it doesnt feel like a 4000 lbs. car in any way. but if you are looking to lighten it up, you could start with the insulation under the hood and in the door panels, as well as in the trunk. from there you could look at light weight wheels, and carbon fiber if such a thing exists for this car yet. but IMO, you just gonna waste your time for the gain that you 'might' get. interior noise will also be a problem as well.

    I hear pulling the engine will shave some poundage off the G8.

    Yeah, but that brings up a whole different problem. . . you're nose will be to high since you took all the weight off the front. The solution is simple, and kills two birds with one stone: cut some coils. Now it's lower and lighter!

    I've driven a G8 GT... didn't feel so light to me. It felt heavier than my mom's CR-V (probably because it is). Anyway, I'll wait for the GXP and see how that does.
