The Pontiac G8 has plenty of interior space, and fit and finish are first-rate. “Obvious cheap-outs are absent,” notes Car and Driver. “The G8's overall refinement puts past Pontiacs to shame,” agrees Edmunds.com
The lack of a pass-through to the trunk is an issue many publications, including Car and Driver, brought up, but according to Jalopnik, “the back seat has ample room for any number of Kama Sutra positions.” Being a family-oriented car site, we can neither confirm nor deny that statement.
Cars.com adds that the G8 “holds its own” on rear-seat comfort and roominess compared to the Charger and Ford Taurus.
In terms of cargo room, the G8’s 17.5-cubic-foot trunk sits midway between the 16.2-cubic-foot trunk in the Charger and the 21.2-cubic-foot trunk in the Taurus.
Besides the use of some questionable interior plastics, only a few objections arise, and they regard the placement of certain controls. Due to Australia’s affinity with right-side-drive cars and because the Pontiac G8 is sold as a Holden in Australia, some controls are located universally to make manufacturing different versions easier. Cars.com glares at the placement of the window controls “dead center below the shifter on the center console.” They also gripe that the front-seat-adjusting knobs are “quite hard to rotate.” Kelley Blue Book notes the controls issue, while Edmunds.com just doesn't like the “'80s-style digital readouts for battery life and oil pressure, the cryptic control icons, and the lack of a redline indicator for the tachometer.”
