The Renault Captur fits the bill. It's only slightly longer but offers anything up to 616 litres of boot space. Admittedly, that's with the sliding rear bench positioned all the way forward, leaving rear seat occupants with minimal legroom, but even if you don't do this, there's an impressive 484 litres on offer. Just bear in mind that E-Tech models lose quite a bit of space, so they are worth avoiding if boot volume is of importance to you.
