If you’ve heard it once, you’ve heard it 12 times now: The 2011 Jeep Grand Cherokee is our most popular review of the week, and it’s been that way for almost the whole summer. New this week and at No. 2 is MotherProof.com’s review of the 2011 Subaru WRX STi. The 2011 Chevrolet Cruze inches up again this week to No. 4, as the vehicle officially goes on sale. The 2011 Ford Mustang rejoins our list, which together with the WRX, bumps off the 2010 Hyundai Santa Fe and 2011 Scion tC off the list for now.
