| 2015 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 | ||

Rear seats are narrow and hard. The centre seat is only usable for very small people on very short trips. see full Mercedes-Benz C-Class review |
