The problem with the G6 (and the previous Grand Am and Alero) isn’t that it can’t be quick, it’s that it doesn’t feel well doing it. Hopefully with the updated Epsilon chassis they can fix this. The Aura I drove was very good. Much better than the Malibu and 9-3, an improvement over the G6.
The G6 is a very heavy car too. It’s difficult to make a 3600lbs FWD car feel sporty. I wouldn’t be surprised if the next Accord tipped the scales at around 3500lbs either.
