THAT tough guy of the Nisan range, the Navara pick-up has become more powerful and more eco-friendly.

Already the holder of the International Pick-up Award 2016, and renowned for its tough attitude and robust performance, the entire range has now switched to a more advanced and eco-friendly Euro 6 engine.

The upgrade covers both the 190ps twin-turbo and 160ps single turbo versions of the Navara's 2.3-litre dCi diesel engine.

It makes a significant difference to the pick-up's environmental performance - a vital consideration for buyers since it affects running costs. CO2 emissions now start from as low as 159g/km, a reduction of 8g/km on the predecessor Euro 5 engine.

It's an enhancement which makes the Nissan Navara the best in its class. Fuel consumption on the official combined cycle has improved to 46.3mpg, up by 1.4mpg.

The Nissan Navara Euro 6 also benefits from a reduction in oxides of nitrogen (NOx) thanks to the addition of a Selective Catalytic Reduction (SCR) system.

An AdBlue tank has been fitted to the Navara, with a filler flap on the opposite side of the vehicle to the diesel tank to avoid confusion. The tank can be filled from bottles or pumps, for maximum flexibility for the user. It will hold 17 litres of liquid, allowing up to 7,150 miles between refills.

Driver assistance messages relating to the AdBlue system have been integrated into the Navara's colour LCD combimeter, the central information screen set between the two main dials.

A number of other enhancements have been made to the Navara's specification including an Idle-Stop System (ISS) for reduced fuel consumption which is now standard on all manual models.

The Navara range now comes with cruise control with speed limiter, Bluetooth hands-free audio and multi-function controls on the steering wheel.

Available in Double Cab and King Cab body styles, the new Nissan Navara is a heavy duty one-tonne pick-up that's built to tackle all terrains.

Marking the Navara out from its rivals is the Double Cab's five-link coil-spring rear suspension system, which provides enhanced performance and comfort over all surfacess. The Navara also features Nissan's standard five year, 100,000 mile warranty which is fully transferrable to future owners.

The improvements to the Navara are part of Nissan's plans to fit eco-friendly systems and advanced technology to all of its models. The Navara is also available with Nissan's Around View Monitor (AVM) camera system, and with Forward Emergency Braking (FEB) - systems which have proved popular on Nissan's best-selling range of crossovers, the Juke, Qashqai and X-Trail.

Prices for the Navara line up range from £22,995 to £31,845 including VAT.
