@chevtothemax Here are some interesting interior metrics that you can use to see the difference between a midsizer like a Malibu/Regal and a compact (Cruze):

That said, the Regal and Malibu are on the smaller side of the midsize segment… but their larger size is still felt in the dimensions of the vehicle (length and width) as well as the width of the cabin. I expect the next-gen midsizers from GM to add an inch or two to the wheelbase and grow interior volume accordingly, if not more — since space efficiency is paramout nowadays.
