The Navara D22 range is aimed to appeal to customers looking for an efficient yet powerful work vehicle designed to handle a rugged working week on the farm or building site.

The new line-up includes both dual cab and single cab variants, all powered by a new 2.5-litre turbo-diesel engine matched to a five-speed manual transmission.

In addition to the four-wheel drive dual cab and single cab models, the Navara D22 will also be available as a two-wheel drive single cab for those customers who don't require the additional off-road capability.

Under the bonnet, the inter-cooled YD25 turbo diesel engine produces a maximum power output of 98 kW at 3,600 rpm and 304 Nm of torque from just 2,000 rpm.

The 16-valve, double overhead cam YD diesel features second-generation common rail technology for lower emissions and excellent economy, a variable nozzle turbocharger which delivers lower emissions as well as more power, and a new balancer system for greater refinement.

The common rail system fuel injection system used in the 2.5-litre diesel has a electronically-controlled high pressure fuel injection pump for greater efficiency. This helps provide more power, low emissions and lower levels of noise, vibration and harshness (NVH). Emissions are further improved by the adoption of an oxidation catalyst.

A new turbocharger with a variable nozzle turbine (VNT) sharpens the engine's responses and also helps lower emissions, while the addition of an intercooler, mounted ahead of the radiator, increases power. The compression ratio is now 16.5 to 1.

The adoption of twin counter rotating balancer shafts within the engine to reduce vibrations and the use of a single, rather than double, chain camshaft drive help ensure high levels of refinement.

Fuel consumption on all models is impressive with the 4x2 single cab returning a healthy 7.3L/100km, while the 4x4 single cab achieves a combined cycle of 9.1L/100km and the 4x4 dual cab ST-R just 9.2L/100km.

With plenty of torque on hand, the 4x2 Navara can tow up to 1,500 kg (braked), while the 4x4 variants are rated to 2,800 kg (braked).

All models across the range feature double-wishbone front suspension with an anti-roll bar and solid rear axle with leaf springs and a limited slip differential.

Externally, the Navara D22 carries over the styling of the previous model with the addition of a bonnet scoop for the new inter-cooled turbo diesel engine.

On the single 4x2 variant, the equipment list reflects the customer's needs with power steering, single in-dash CD player, air conditioning, dual front airbags and anti-lock brakes as standard.

The 4x4 line-up starts with a base single cab DX with standard power steering, air conditioning, single in-dash CD player and 16-inch steel wheels. Dual front airbags and front seatbelt pretensioners are available as a $500 option.

On top of the 4x4 DX single cab's equipment, the dual cab ST-R adds standard dual front airbags with anti-lock brakes, an alloy sports bar, side steps, front bucket seats and 16-inch alloy wheels.

Pricing across the range is sharp, with the 4x2 single cab DX starting at just $22,490*, while the 4x4 single cab DX starts at $30,690*. The popular ST-R dual cab 4x4 is priced from $38,490*.

Nissan's general manager of marketing, Ross Booth, said: "The Navara D22 is a tough as nails work ute which offers outstanding value in this segment".

"Navara D22 is a very popular model in this market and from our experience with the superseded 3.0-litre model we are sure this one will continue to build on its sales success," said Mr Booth.
