NISSAN, has announced engine, chassis and technical upgrades for the NV400 van at the recent Hannover show.
Introduced to great acclaim in 2011, the NV400 has proven to be a front-runner in the heavy van and chassis cab segment of the market – thanks to its versatility, the wide choice of models and the strength and standing of the Nissan dealer network.
The 2015 NV400 builds on this reputation to create a formidable range of highly efficient vehicles perfectly in tune with today’s demands for a practical working van with a low cost of ownership.
Some the most significant changes can be found underneath the familiar body, where the range of dCi engines has grown to five, offering more performance and greater refinement. But despite the power increases, fuel economy is actually better than before.
All have a common base – a state-of-the art 2.3-litre common rail/direct injection, four-cylinder, 16-valve turbo diesel developed by Alliance partner Renault.
A pair of single turbo units produce 110hp/285Nm (previously 100hp) and 125hp/310Nm and these are joined by a pair of newly developed Twin Turbo units, developing 135hp/340Nm and 165hp/360Nm. Also available is a 150hp/350Nm version of the engine that has a variable geometry single turbo and is available only with a robotised semi-automatic gearbox.
The new Twin Turbo models are seen as ideal for vans and chassis cabs needed for heavy-duty work or for longer journeys. The technology uses a small turbocharger to generate increased torque at low revs (up to 1,500 rpm) for more rapid acceleration at city speeds or when fully laden.
At higher engine speeds, the larger turbo takes over to provide more power and a usefully wider torque band that is especially appreciated at motorway speeds. Thanks to this increased flexibility, there is less need to change gear to maintain momentum. This not only reduces driver fatigue but also enhances fuel economy.
The Twin Turbo models also benefit from Stop & Start technology and regenerative braking via a new Energy Smart Management (ESM) system that together enables the 165hp version, for example, to return an impressive economy figure of 6.9litres/100km over the combined cycle.
It is estimated that the new 165hp NV400 will consume up to 1.5 litres/100km less than its 150hp predecessor, a significant saving of up to £1,200 over three years.
Drivers can contribute to improved fuel economy as well: the new NV400 has a number of on-board eco-driving aids including driving style and gear shift indicators and an ECO mode switch which limits harsh acceleration by limiting available engine torque as well as optimising the climate control system settings.
