Nissan has unveiled two new van concepts ahead of the upcoming Tokyo motor show – the Paramedic Concept and the all-electric e-NV200 Fridge Concept.

The new NV350 Caravan-based Paramedic Concept is Nissan's fifth-generation ambulance and builds on the success of previous versions of the Japan-only vehicle. The ambulance carries a lithium-ion auxiliary battery that supports life-saving medical equipment, uses Nissan's industry-leading Intelligent Around View monitor to help the driver and other technology to reduce the spread of germs.

Nissan plans to begin sales next year.

Nissan will also launch the modified all-electric Nissan e-NV200 Fridge Concept, which is equipped with an additional battery pack in the cargo space to power a refrigeration unit.

'Our fifth-generation ambulance will offer enhanced features that will make a real difference to people's lives,' said Ashwani Gupta, senior VP of Renault-Nissan's van division. 'The new Paramedic Concept contains vital life-saving equipment to respond to emergencies, often in remote areas.

'Meanwhile, the e-NV200 Fridge Concept will create huge value for commercial users – generating more business, as well as reducing the cost of ownership. With zero emissions, it'll be perfect for busy urban environments where larger vehicles are often prohibited.'
