This wheel arrangement allows entry and exit at four points around the vehicle's perimeter. The CityCar was designed for front entry, which is feasible because there is no engine in the way. Baggage and emergency entry and exit are at the rear, and there is no side entry and exit. This configuration allows nose-in parking to the curb, and passenger embarkation from the sidewalk rather than from the road, which allows the elimination of the need for side clearance between parked vehicles. It also simplifies the vehicle, which does not need to accommodate door openings. The CityCar was designed with a collapsible frame through a four-bar linkage that enables the vehicle to fold up for more compact parking, making possible to stack three or four CityCars in the length of a traditional parking bay, a particularly efficient feature in crowded urban settings. Safety systems operate at multiple levels. The car's folding mechanism also provides space for crash-deceleration systems. Its electronic sensing and wireless communications contribute to reduce the likelihood of crashes. And if a crash occurs, the low mass and relatively low speed reduce the energy involved in a crash with a similar vehicle. Seat belts and airbags will still be needed. The CityCar was controlled with a joystick or optionally an electronic steering wheel. The prototype was long and folds to when parked, and weighs less than . The top speed is and to which it can accelerate from rest in 3 seconds. The all-electric range is . The lithium-ion battery pack is located in the floor and can be recharged in 12 minutes. The electric car will be capable of climbing grades up to 20 percent. The CityCar was 60% the size of a Smart Car, and its lithium-ion battery pack delivered the equivalent of 150 to 200 mpg-us (1.2 to 1.6 L/100 km; 180 to 240 mpg-imp) with no tailpipe emissions. The Spanish consortium Hiriko Driving Mobility licensed the design to build a commercial model called Hiriko based on the concept of the CityCar for testing in several European cities. Production of 20 test pre-production cars began in 2012 in Vitoria-Gasteiz. The first demonstration trial was scheduled to begin In Vitoria-Gasteiz by late July 2012. The trial was to begin with 6 Hirikos as part of a carsharing program run by the city, with two pick up/drop off points, and the service will be available to all citizens at a cost of () per hour.
