Sur le site Edmunds.com.on reconnaît le p'tit quelque chose de spécial de la GXP, mais ils se demandent si la différence entre les performances de la GXP et celle de la G8 V8 en valent vraiment la peine, considérant l'écart de prix...

Selon leur évaluation. la G8 donne une sensation de conduite très semblable et performe tout aussi bien sur une route vallonneuse. Freinage 60-0 quasi-identique (113 pi. vs 110)
On our standard handling loop through the canyons, the GXP acquitted itself well despite its prodigious 196.1-inch length (5 inches longer than a BMW 5 Series). Body roll is kept in check by the sport-biased FE3 suspension, and the light steering is quick and responsive. Tire-smoking power oversteer is a cinch out of 2nd-gear corners, yet the GXP always feels stable and predictable, even when you're going sideways. However, we feel the G8 GT with its FE2 setup is equally competent — its slalom speed at our test track was virtually identical to the GXP's, and there are few if any discernible handling differences from behind the wheel.
Braking performance was excellent at 110 feet from 60 mph, though the GT once again nips at the GXP's heels with its 113-foot panic stop. As for fuel economy, EPA estimates stand at 13 mpg city and 20 mpg highway for the GXP, which is considerably worse than both the GT (15/24) and the LS3-powered Corvette (16/26). We averaged a woeful 15.4 mpg in our GXP — but if you're interested in this car, that's probably not cause for concern.
D'autre part, Si GM a mis un prix de lancement alléchant, il a rapidement augmenté celui-ci... Le prix de base pour une G8 V6 est maintenant de 32,500$, ce qui la place dans un segment très compétitif.. La V8 elle, débute à 37,500$... Territoire encore plus compétitif...
Sort de ma liste de sélection... à près de 40,000$ j'irai sur une G37 bien avant...
