Chevrolet's Uplander minivan receives some significant equipment revisions for 2007. The Uplander's previously optional 240-horsepower, 3.9-liter V-6 is now standard — a much-needed provision, considering most competitors outgunned the Uplander's previous 200-hp V-6. An electronic stability system is now also standard, but the Uplander's previous all-wheel-drive option has been discontinued.
