Sono Sion series design '03.2019

The Sion boasts up to 250 km (155 mi) of "normal" range per plug-in charge of the 35 kWh battery pack, with fast charging and regen braking supported. Its 120 kW motor produces 290 Nm (214 lb.ft) of torque, and can go from standstill to 100 km/h (62 mph) in under 9 seconds, on its way up to a top speed of 140 km/h (87 mph). It's also expected to be able to comfortably tow up to 750 kg (1,653 lb).

The five-door Sion has grown bigger than the prototype before it too, and has been treated to a more emphasized rear end. The 4,290 × 1,830 × 1,670 mm (168.9 × 72 × 65.7 in) dimensions make room for a larger footwell and extra interior space.
