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

2014 BMW i8 Seat Room and Comfort: Cons
Year	Comment
	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

2007	4dr SUV 268-horsepower 3.5L V6 7-speed shiftable automatic AWD	3rd row seats are big enough and comfortable enough for an adult. 2nd row seats are the best captain chairs I have ever sat in in a car. Glass roof gives additional room appearance. see full Mercedes-Benz R-Class review

2006	4dr SUV 268-horsepower 3.5L V6 7-speed shiftable automatic AWD	The STANDARD leather seating surfaces on the 2006 front seats - way better feel than artico leather. The adjustment range to get things just right and the head rest. Very cozy. see full Mercedes-Benz R-Class review
