About the 2008 Pontiac G8

The Pontiac G8 represents GM's final attempt at importing Australian muscle, arriving as a rebadged Holden Commodore just before the brand's demise. Built on GM's Zeta platform in Elizabeth, Australia, the G8 Base packed a 3.6L V6 producing 256 horsepower, while the GXP variant delivered 415 hp from its 6.2L LS3 V8. Only produced for three model years, total G8 production barely exceeded 38,000 units, making these increasingly rare finds. The sedan's rear-wheel-drive layout, near-perfect weight distribution, and European-tuned suspension delivered genuine sports sedan dynamics that American buyers hadn't seen from GM in decades. Today, clean examples command strong prices among collectors who recognize the G8 as both Pontiac's swan song and proof of what GM could achieve when it imported the right platform. The GXP variants are particularly sought after for their LS3 powerplant and manual transmission availability.
