In the context of larger hot hatches such as the Honda Civic Type R, of course the Up GTI lacks space overall, but relative to its immediate rivals it’s good. In the front, there’s plenty of head and leg room for tall adults.
Thanks to the boxy exterior, it’s not too shabby in the rear, either; there's at least as much room as there is in a Renault Twingo GT, and much more than an Abarth 595 offers. That means two six-footers can just about get comfortable behind a couple of beefy occupants sat in the front.
Storage space is also impressive, with wide, deep door pockets and a single cupholder located centrally at the bottom of the dashboard. The glovebox isn’t much cop, though.
Where the Up GTI really scores over the Twingo GT or 595 is its boot. It’s a usefully square shape but, unlike the shallow boot of those rivals, the Up GTI’s is deeper – albeit with a sizeable load lip to lift heavy items over. Still, the fact that it’ll take three of carry-on suitcases more easily than those two cars makes up for that.
Need more room? Then simply drop the standard one-piece folding rear backrest and, hey presto, you have it. With the seat folded, there’s a sizeable step left in the extended boot floor, but simply lifting the standard dual-height boot floor to its higher setting helps level this out.
