On sale this month, the updated Navara ST-R will come with chrome power mirrors, revised interior colours, including new black seat trim, revised suspension and wider 265/70R16 all-terrain tyres.

Nissan has also fitted a standard driver’s side airbag and front seatbelt pretensioners to the Navara ST-R. An optional passenger’s side airbag is also available for $450.

The changes are available on both the petrol and diesel variants, which are equipped with either a 125kW 3.3-litre V6 or a 110kW ZD30 3.0-litre turbo diesel engine respectively.

The ZD30 diesel is Nissan’s most popular Navara variant, thanks to its effortless performance, refinement and economy.

Both engines are available with a five-speed manual transmission on the 4x4 models.

The Navara 4x2 range offers two models, the DX single and dual cabs. Both come with a 2.4-litre DOHC four-cylinder engine and are available with either a five-speed manual or four-speed automatic.

Prices start at $19,990 for the DX single cab and $25,490 for the DX dual cab. For $2000 extra both models get an optional automatic transmission.

The Navara 4x4 range includes one single cab model, the DX 3.0-litre turbo-diesel, which comes with a five-speed manual transmission. Pricing starts at $33,340.

Both DX and ST-R variants are available in the 4x4 dual cab range with the choice of either diesel or petrol engine. The DX 3.3-litre petrol is priced from $36,340 and the DX 3.0-litre diesel is priced from $38,840.

Pricing of the updated Navara ST-R models has increased by just $500, with the Navara ST-R 3.3-litre petrol now starting at $40,990 and the ST-R 3.0-litre turbo-diesel starting at $43,490.

Since its launch in 2002, the Navara ST-R has been a runaway success for Nissan. The ST-R accounts for over 60 per cent of total Navara sales and at the end of calendar year 2003 total sales were 40 per cent up on the same period in 2002.

Nissan Australia’s commercial vehicle product manager, Andrew Dimsey, said the revisions to the Navara ST-R will be well received as many of the changes were requested by customers.

“ST-R is the best selling model in the Navara range and the additional features and modifications should prove very popular with our customers.”
