On the last day I had this car, I got another chance to drive a Hyundai Sonata, this time a 2013. I rented a Sonata last year and
wrote about it here. They are similar in terms of features. Both have the manual-auto six speed gear box. But on balance, although I wish I could say differently, the Sonata is the better car. The Sonata transmission shifts better, and it stays in the selected gear better and is therefore more amenable to the upshifting hypermile strategy with these automatics. The Chevy felt like the tranny could fall off when shifting from neutral to drive; not so with the Sonata.
