As its name implies, the Toyota Prius+ is basically a bigger version of the Prius – a hybrid seven-seat MPV. That makes it an alternative to models such as the Ford S-Max or Vauxhall Zafira, although both of them come only with conventional petrol and diesel engines and don’t offer a hybrid model. Even from the outside, it’s clear that the Toyota Prius+ is very much a part of the Prius range, and that family look continues inside. Drivers of the regular Prius hatchback will feel right at home in a Prius+, as the design is virtually the same. However, that also means that the Toyota Prius+’s cabin is dominated by swathes of grey plastic. On the other hand, there’s no criticising the amount of space on offer. As you’d expect from a people carrier, it has loads of space inside. There’s plenty of room in the front, and reasonably tall passengers will be comfortable in the middle row. Even the third row of seats is reasonably spacious, although they’re more suitable for children than adults. Fold down all the rear seats and you have 1,750 litres of space to play with – which is far more than in a standard Prius. In five-seat mode, the boot will take almost 800 litres – which is impressive – and although it shrinks to only just over 200 litres with all seven seats upright, that’s not significantly worse than you would find in any of the alternatives. It’s a shame that the wheelarches intrude into the available space, but the rear seats do sit flush with the floor and the boot lip when they’re folded down, which makes the Prius+ easy to load and unload.
