Suzuki unveiled the Waku SPO concept at the Tokyo motor show, where it instantly stood out for its retro, compact design and having a touch of the Honda e about it.

But it had a far more interesting feature: the ability to morph into different body shapes. The Waku has a boxy estate style, yet while chatting to the car’s designer on stage, someone pressed a button somewhere, and it changed into a coupé.

Designer Takafumi Ogisu explained: “At first, it is a wagon model, but then it changes to a coupé model. If it is a coupé model, you can enjoy driving. If it is a wagon, then rear seat space is much bigger for the family.”

It’s a novel idea, if perhaps a little flawed in execution. There wasn’t enough time to ask about the storage solution, but the way the estate’s roofline drops down into the boot space suggests that storage for the family may be non-existent.

Still, this is just a concept and there are no plans for production – although Ogisu said he’d like to see details such as the side-view cameras, headlights and front grille make it onto other Suzukis.

The front of the car and the digital screens inside are two more elements that can change on the Waku concept. For example, Ogisu said the headlights can be swapped depending on a driver’s preference. Such changes seem far more feasible than the coupé/estate idea since they involve software rather than hardware.
