The Civic Si Sedan's trunk is big and fully lined, including the trunk lid itself. It's not unusual for cars with short rear decks like the Civic to have ridiculously small trunk openings – the Chevy Cobalt is particularly egregious – but the Civic somehow manages to be big enough that even a large suitcase will slide in without difficulty. Longer loads can be accommodated with the 60/40 split rear seat, which has release handles located conveniently at the inside edge of the top of the trunk opening. We were surprised by the old-school cargo-crunching hinges, though.
