More and more people are interested in the convenience and economy of small car ownership – but many are put off by the small carrying capacity that goes with it.

This handy German gadget operates as an aerodynamically efficient and better-looking alternative to the roof rack – the Auto Rucksack is exactly that – a backpack for your small car that clips on to give you extra storage, and clips off to become a suitcase or sports bag on wheels.

The Auto Rucksack is simple to use – see this video (5.6mb, mp4) for a demonstration – and a very quick and convenient way to add 120 litres of waterproof storage to your compact car at a maximum 20kg loading. When it’s off the car, it operates as a luggage trolley, and when not in use, it folds up to a compact size for storage.
