In a rear crash, passengers will appreciate the large head restraints perched atop the back seat, but when they’re not in use they block visibility. Since the G6 Sedan’s rear window is steeply raked and the deck is tall, this can make relying on the giant side mirrors almost a necessity when backing up. Forward visibility is excellent, and blind spots are almost non-existent thanks to the large, triangular side mirrors. The rear roof pillars are not wide enough to make reversing from slanted parking spaces difficult.
