Rinspeed, the company that created the Squba, a car that works underwater, has unveiled its latest concept vehicle; the UC? Making its debut at Geneva, the UC? is all-electric, has two seats and a unique ‘train loading’ system that allows the car to easily fix into a train carriage for longer, inter-city journeys. It’s more than that, though – Rinspeed calls it a ‘new mobility concept’. The idea of the tiny car is to make emissions-free journeying as easy as possible, regardless of distance. The car itself only has a 65-mile range, which is enough for day-to-day commuting but not much else, so there’s an internet connection that allows drivers to book the car onto a train to cover city-to-city distances.
