TrueDelta Reviews the Seat Room and Comfort of the 2014 BMW i8

2014 BMW i8 Seat Room and Comfort: Cons
YearComment
The Cadillac ELR's rear seat is very tight for the average adult, but a couple 5-9 or under can sit back there without outright discomfort. The BMW i8's rear seat is so tight and so vestigial that putting all but the shortest people back there borders on cruel and unusual punishment. I squeezed into the i8's back seat to photograph its instrument panel interior and almost couldn't get out. For those who want an adult-friendly rear seat, the Tesla Model S is far superior to either coupe. see full BMW i8 review

2014 Cadillac XTS Seat Room and Comfort: Pros
YearComment
2014 The generously sized front buckets inside the XTS are among the most comfortable and supportive you'll find, assuming you like your seating on the firm (if not quite Audi-firm) side. Those seeking a cushier seat with an optional massager (not offered in the XTS) will find one in the MKS. Both cars' front seats provide more lateral support than you might expect from America's remaining large luxury sedans, but still not a lot. After all, hardcore canyon carving isn't the primary objective. Despite their much larger number of adjustments, I found the Audi A8's front seats to be overly firm and less form-fitting than those in the Detroiters. The rear seat of the XTS is also quite comfortable--for two people. Basing the XTS on GM's Epsilon platform, originally created for much smaller cars, has a cost. It's much cheaper and easier to lengthen a platform than to widen one. So the XTS is essentially a stretched midsize sedan rather than a truly large one. Rear legroom is abundant despite insufficient space for feet beneath the front seats, but the cabin is decidedly midsize in breadth. The compact Dodge Dart (admittedly wide and heavy for its class) provides as much space for shoulders. Rear seat passengers sit much closer to the front seats in the MKS, which consequently doesn't feel nearly as roomy in back. But the Lincoln's rear seat cushion is higher off the floor, and so provides better thigh support for adults. The Audi easily provides the most space for three abreast. For XTS-matching legroom, though, you'll have to step up to the extended wheelbase version. see full Cadillac XTS review
