    Will the added power make this Grand Prix a hit?

    We'll see, but as I understand it, at least the initial run of the GXP will be a 2005, not 2006, though the Chevy 'versions' will be a 2006.

    Thinking 40+ more HP and 40+ more TQ than the GTP at the same curb weight makes it interesting, at least . . .

    Maybe - having owned both the 3800's (normally aspirated & supercharged); even though the GTP had 40 more hp & 50 ft-lbs than the GT. With the enhanced TC, the GTP had less torque steer and wheel spin. I expect Pontiac has played with the TC, it will also have Stabilitrak and the GXP will have larger(wider) front tires. The aluminum V8 doesn't appear to have affected the weight balance much, so the GXP will be fun. I can't wait to drive one.

    I wonder what the average selling price will be. I configured one on Edmunds, and got a tmv of a Shade under 36K. That seems pretty Steep.

    They shouls have given the GXP more standard equipment. I was surprised by the loaded price of $35K+. I cant believe they didnt make leather and the uplevel sound system standard.

    The GXP will have most of the upgrades of the GTP + Comp G package (HUD,Stabilitrak,TAP shift...) I've read that Pontiac will price the GXP at ~$29k. with some options $32k-$33k will load one up nicely. It could go to $35k but they will be pushing their luck.
    The GXP is only 17 lbs heavier than the GTP so HP to weight ration improves.
    Check out this link for the equipment and options:

    Obviously they are pricing it in anticipation of rebates. I dont think $30K is too much considering the power of this car, but $35K loaded isnt going to work. They made the performance hardware standard, but not the luxury features.

    I have to disagree with the GTP having LESS torque steer and wheel spin then a GT, having owned a 1997 and now 2002 GTP coupe and driven many renta car GT sedans.. my GTP has DEFINITELY MUCH MORE Wheelspin and a little more torque steer then the GT did. That was stock. Of course now with 300+ modified hp, it really has wheelspin, LOL!

    One easy change I have done to all my GTP is get rid of the avg P225 60 16 tire size and PUT P245 50 16, fit perfectly fine and doesn't mess up your ABS/traction at all. That way you get more traction and better handling, works for me. It also slightly lowers the car with that tire size, looks nice!

    My GTP had the enhanced TC and my GT the std. TC. The ETC got the spin and torque steer under control much better. I could spin both very well, but the ETC was less erratic.
  • gunitgunit Posts: 469
    The ETC and ABS control systems on the GTP is by Bosch, GM/Delphi or whoever used to do the TC/ABS on the GT. Not sure today about the GT. Regardless it is still too much power for a front drive car. Should have been rear drive. Oh well.
  • rayainswrayainsw Posts: 2,964
    My understanding is that the new GXP V8 GP will have the same EPA rating as the CompG (18 / 27) but with 43 more HP an increase in TQ also by 43, and essentially the same vehicle weight . . .

    Not too shabby.

    When I went to the autoshow in January the Ponitac info on hand said teh GXP would be out in April. I dont know if that's true or not because they have not updated the website with any info regarding the GXP.
  • ocmike3ocmike3 Posts: 232
    From articles I have seen production was supposed to start this month (March) which usually means deliveries 6 - 8 weeks out minimum. Pontiac has been very quiet about the launch and not putting out any updates that I have seen.
    I can't wait to take one out for a test drive and see how it compares to the current GTP. The suspension modifications should improve control and handling.

    LS4 link:

    http://media.gm.com/division/2005_prodinfo/powertrain/2005%20HPT%20Library/Gen%20IV/2005i_- - - 5300_LS4_Grand_Prix_GXP.pdf

    Looking at the Graphs for 3 motors (the LS4 5.3L V8, the Northstar 4.6 and the ‘old’ L67) I find the following of interest:

    = = = = = = 5.3L . . . . 4.6 . . . . L67

    HP @ 2000 . 115 . . . . 100 . . . . 100
    TQ @ 2000 . 300 . . . . 265 . . . . 250

    HP @ 3000 . 180 . . . . 150 . . . . 160
    TQ @ 3000 . 310 . . . . 275 . . . . 270

    HP @ 4000 . 245 . . . . 225 . . . . 220
    TQ @ 4000 . 320 . . . . 295 . . . . 280 (past peak)

    [these numbers are approximate, from these dyno curves - trying to line this data up as a chart . . .]

    Point being, compared to the L67 (a known and appreciated torque generator) and the Northstar (I have driven the new STS with this version of the motor – it is technically sophisticated, expensive to produce and I certainly respect it), this new 5.3L V8 quoted output is quite impressive. At least on paper.

    I end up spending a LOT of my drive time with the motor turning between 2000 and 4000 rpm. The torque available in this range is more important to me (most of the time) than peak horsepower.

    The 5.3L LS4 generates more torque and more horsepower at every point from 2000 to 4000 rpm than either of these other motors.

    I am looking forward to driving this car.

    The rep at the NY Auto Show said the GP GXP pricing will start at around $30,000 - Which is around $4000-$5000 less than the Bonneville GXP and you sacrifice nothing - Bonneville is not nearly as ergonomic as GP and both appear to be almost the same size. The GP GXP HP is rated higher than Bonnevilles (290 Vs. 275). I will still want to test drive this thing first - I am a big heavy guy and I need a big heavy car to combat the NYC highways. I'm not sure how durable anything smaller than an Impala SS or Lexus 330 will be. As it stands right now the GP GXP is the most perfect balance of performance & luxury I saw at the auto show for the $30000 - $36000 MSRP Price range.
  • gunitgunit Posts: 469
    The GP GXP will be a much better buy then GXP BOnny was. Actually the GP GXP is rated at 303hp, not 290. Even better! I would have to go with the GTO as one of best blends of luxury performance for under $35k. Interior is MUCH nicer then Grand prix, many magainzes call GTO one of GM's BEST interiors, better then Vettes. Seats are much nicer esp backseat then grand prix as well. As for a heavy car, the GTO is 250 lbs heavier then GP GXP. 3750 vs 3500
  • 14871487 Posts: 2,407
    The GXP is no smaller than an ES330 but it is smaller than the Bonneville. The pricing for this car is already on edmunds. Fully loaded it would cost about $35K which is too steep if you ask me. If you could get it loaded for $31K-$32K than I would be happy.
  • cfazzaricfazzari Posts: 77
    32K or 33K is my absolute maximum. Whatever I end up gettting will cost that and no more. So if the Pontiac Guy wants the business that's what they will get from me. If they don't want to deal I can probably convince the Chevy Impala SS Guy or the Chrysler 300 Guy or even the Mazda Speed 6 Guy to deal (The Lexus ES300 Guy may not be as willing to bend)... And if I have to wait until the end of the 2006 (yes 2006) model year I will. My dad used to say buy a car when you DON'T need one....smart guy he was too.

    I am amazed the GTO is heavier than the GP GXP. The GTO looks like a sculptured Grand Am.
  • The GTO is much larger then a Grand AM and has the additional weight of the independent rear axle assembly. Even heavier the GTO is MUCH quicker then a GP GXP.
  • gunitgunit Posts: 469
    Also not to mention that the GTO interior/seats is MUCH Nicer then the GP GXP. Sit in both and compare. One of GM's best interiors from what I read in Consumer Reports and Car & Driver and experienced. For GM I was quite suprised.
