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

2015 BMW 3-Series Gran Turismo Seat Room and Comfort: Pros
YearComment
2014 Though the latest 3-Series has a much roomier back seat than its predecessors, many people still find it insufficient for their needs, and step up to a midsize sedan or wagon such as the 5-Series or E-Class. Well, most of the 3-Series Gran Turismo's wheelbase stretch was put towards rear seat legroom, bumping it from 35.0 to 37.9 inches. Though a larger car, the E-Class has nearly four inches less total legroom--barely more than the 3 wagon, in fact. (But with a more comfortably positioned rear seat than the 3 wagon.) What the specs don't tell you is that the 3 GT's rear seat cushion, since it is positioned much higher than that in the wagons, provides better thigh support and a much more open view forward. To top it off, the 3 GT's rear seat back reclines. Here again, though, the E-Class wagon has a trick bonus: a rear-facing third-row seat. Though there's not enough headroom back there for anyone over 5-4, the seat is well-padded. If you want to seat seven in a pinch, the E-Class wagon is your only option with a sedan-like driving position (aside from the Tesla Model S). Update: this review originally stated that the 3GT has much more shoulder room than the regular 3-Series, and about as much as the E-Class. But it seems that the initial specs were inaccurate. The latest specs suggest shoulder room in the 3GT is about the same as that in the regular 3-Series. Its interior does feel significantly roomier, though, so the initial specs could yet provide the more accurate set. see full BMW 3-Series Gran Turismo review
