The event at the NEC will provide the platform for a new diesel engine, which develops 75hp but brings CO2 emissions down to 109g/km.
The van will also make better use of fuel than the current engine line-up. It will offer combined cycle fuel economy figure of 68.9mpg.
The engine has been designed for the Citroen Nemo to improve efficiency and comply with new European emissions regulations.
This means the van is now ‘Euro 5’-compliant thanks to its use of fuel-saving technology such as a Stop & Start system.
The Citroen Nemo van is fitted with an EGS transmission, which boosts fuel economy over a standard five-speed transmission by almost five per cent.
Other measures taken to improve the environmental performance of the Citroen Nemo include a self-regenerating Diesel Particulate Filter System (DPFS) to reduce the amount of harmful diesel particulates emitted from the tailpipe.
Despite the extra green measures, the Citroen Nemo HDi 75 is capable of carrying 660kg – an increase of 50kg over the older models.
The van also gains more space in the rear thanks to a new folding passenger seat and the level of equipment has been expanded to include air conditioning and rear parking sensors as standard as well as Bluetooth and USB connectivity.
Scott Michael, Citroën’s Commercial Vehicle Operations Manager, said the Nemo ‘offers even better fuel economy, low emissions from just 109g/km, more power and a higher payload.’
It will be unveiled alongside a range of Citroen vans, including a 75hp Berlingo and variations of the Dispatch and Relay vans under Citroen’s ‘Business Class’ tagline.
Michael added: "The ‘Citroën Vans – Business Class’ display at this year’s CV Show highlights the strength and depth of our award-winning LCV range."
