TrueDelta Reviews the Seat Room and Comfort of the 2015 BMW 3-Series

2015 BMW 3-Series Seat Room and Comfort: Pros
YearComment
2014 The BMW 3-Series used to be tight inside, but it has grown with each redesign, especially the most recent one. The rear seat of the current sedan isn't nearly as roomy as that in the related 3-Series Gran Turismo hatchback. But it offers considerably more rear legroom than direct competitors like the Audi A4, Cadillac ATS, and Mercedes-Benz C-Class. In fact, combined front and rear legroom is the same as in the one size-class up, ten-inch-longer Mercedes E-Class. (You do get a half-inch more rear headroom and nearly two inches more rear shoulder room in the Benz.) Beyond the specs, the BMW's rear seat is comfortably high off the floor, a rarity in the age of sedans with plunging coupe-like roof lines. see full BMW 3-Series review
