Volkswagen Commercial Vehicles presented the e-Co-Motion concept electric city delivery van at the Geneva Motor Show. (Earlier post.) The van offers a three-stage modular battery concept to accommodate the different range requirements of customers.
A battery with a capacity of 20 kWh could be installed for driving ranges of around 100 km (62 miles), while a battery with 30 kWh would enable a 150 km (93 mile) driving range. Finally, a battery with 40 kWh storage capacity is planned for the top driving range of 200 km (124 miles). The crossmembers and rib structure of the battery box let it serve a secondary purpose as a load-bearing body element that also helps to reduce vehicle weight.
The electric drive unit is mounted to the rear axle together with a single-speed planetary gearbox to achieve large wheel turning angles at the front axle and thereby the maneuverability that is so important for city operation. As a result, its turning circle is 8.95 meters, which is unique in this vehicle class.
The continuous power output of the compact drive unit is 50 kW, with maximum power is 85 kW; maximum torque of 270 N·m (199 lb-ft) enables good acceleration even in heavily loaded vehicles. Although it was designed for city deliveries on city streets, the electronics of the e-Co-Motion concept do not limit its top speed until 120 km/h (75 mph). This permits driving on city motorways and short intercity routes.
The cabin of the e-Co-Motion focuses on the everyday needs of a transporter: step in, buckle up and drive off. Instead of a selector lever, a rotary gear selector switch is installed, and there is no conventional handbrake lever. In turn, this simplifies walking through via the passenger’s side door, which is also made easier by a folding seat on the passenger’s side.
The control panel addresses nearly all vehicle functions from a central point and displays the necessary information on an eight-inch color monitor. A movable, modular center console features computer, storage compartment, drink holders and 12 V and 230 V accessory outlets.
