So, I've had my GXP since 09. Love the car. She only gets maybe a couple thousand miles a year. Anyways...I couldn't find any info comparing the GXP and the non GXP. I know the engine is different, GXP is turbo, and the few cosmetic differences. Anything I'm missing? I've heard some say that the rear end in the GXP has lsd, where as the non GXP's don't. What about suspension? Anything else I'm missing?

I am new to the solstice, but have been doing a lot of reading. If you buy a non GXP newer than '06 and loaded with every available option the only difference is the engine.

I read a lot of good information on edmunds.com as well as this forum.

 

[kwtoxman]

There are some differences besides engine. I'm sure someone with more time will post...

Here is an ok thread

And post #4 in this thread, I'm not sure how accurate it is but here it is anyway.

Yup, that's about right.

The GXP suspension (springs,shocks,sways) and the motor (and supporting control modules) are the big differences.

GXP Z0k suspension is also different than the NA Z0k suspension which are both different than the non-Z0k versions.

LSD was available on both.

edit: ****, and obviously the front/rear fascia and associated ducting.

 

[King-Oka]

Actually the N/A ZOK suspension is the same as the GXP non-ZOK suspension.

Biggest thing about the engine is the 2.0 turbo is also direct injected, where the 2.4 n/a is direct port injected. This ( in addition to the Turbo) contributes to the added nearly 100 HP in the 2.0.

:agree: :thumbs:

 

[rob the elder]

The GXP has front brake cooling ducts so the fascia and the inner fenders are different.

The 06 all NAs, have the type 1 top, GXPs I believe have type 2 or 3 depending on build date

The engine, cat, exhaust, intake, radiator, slave/throw out bearing, muffler, rear fascia are all different.

The the cooling fan assembly is not interchangeable.

The rear ends are different.

The ECM and software are different

The wiring harness is different.

 

[chickenwire]

100 hp and 3 speeding tickets are the biggest differences. lol

 

[TX08manualGXP]

well, I know I can slide around turns with the throttle pinned on the NA and it slides around and takes off like mad. The GXP however doesn't seem to like it nor wants you to do it do it and activates traction control, esc and pretty much spoils the fun. It's not nearly as fun in the rain either. I'm gonna have to figure out how to disable all that crap so I can drive it my way. they both handle and feel about the same and those with Non GXP's should be just as proud.

Press the Traction Control button.

From the manual:

The traction control system can be turned off or back
on by pressing the ESC/TCS button. To disable
both traction control and ESC, press and hold the
button from five to ten seconds.
When the ESC system is turned off, the TRACTION
OFF and ESC OFF messages appear, and the ESC/TCS
light comes on to warn the driver that both traction control
and ESC are disabled.

Competitive Driving Mode
The driver can select this optional handling mode by
pressing the ESC/TCS button on the console two times
within a five second time period. COMPETITIVE MODE
displays in the DIC. SeeDIC Warnings and Messages
on page 3-40for more information. Competitive Driving
Mode allows the driver to have full control of the rear
wheels while the ESC system helps maintain directional
control of the vehicle by selective brake application. The
ESC/TCS light will be on and the traction control system
will not be operating. Adjust your driving accordingly. This
electronic stability control mode is recommended only for
use during closed track events and competitive driving
venues.
When the ESC/TCS button is pressed again, or the
vehicle is restarted, the ESC and TCS turn back on.
Notice: When traction control is turned off, or
Competitive Driving Mode is active, it is possible
to lose traction. If you attempt to shift with the rear
wheels spinning with a loss of traction, it is possible
to cause damage to the transmission. Do not attempt
to shift when the rear wheels do not have traction.
Damage caused by misuse of the vehicle is not
covered. See your warranty book for additional
information.

For regular driving....Not worth the cost of the GXP, IMO. The only other difference I see, at least in the club I belonged to, was the insufferable arrogance of the turbo owners!

 

[TX08manualGXP]

Ha, no, I have both and was hooked on turbos the second I stepped on the gas. I drive mine to work every day and only drive 2.4 miles and I use the hell out of the turbo. it;s night and day.

Thanks Soup. I didn't try holding the button down and turning both off. I still think the auto braking happens though. I'll test it out this weekend. I wish I could turn off all that stuff and not have to have the idiot light come on though. Too bad you can't have that stuff disabled with a tune. Oh well.

 

[kwtoxman]

It can be turned off completely. Read the manual TX08. There are more options than TS posted.

Oh really? What would they be then?

TIE. Multitasking got me again. The big ones are there. I missed the 5s sentence option in the first paragraph and thought it only discussed the first press stopping TCS. The sonata on the competition mode made me glaze over. I find the manual quote is a little backwards, which got me too. It was giving the biggest change right after TCS, and then the intermediate option after.

I know your usually spot on and should have reread when I thought I saw some missing info.

Frenchy, the rear end ratios are different between the two. N/A has 3.91s and turbos have 3.73s.

 

[King-Oka]

NA folks can always do as I did and Supercharge, and add ZOK suspension. Then the differences are that the NA sounds much cooler, and has better throttle response, therefore is more fun to drive.

I was waiting for that one.

+

shorter third gear
fog/signal light differences
different clutch
different lower control arms
different axle shafts

And the early NA's had different transmission ratios too! :brentil:
