Nissan Navara turbo-diesel
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 98kW at 3600rpm and 304Nm of torque from just 2000rpm.
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 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.
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 improved with the 4x2 single cab returning 7.3L/100km, while the 4x4 single cab achieves a combined cycle of 9.1L/100 km and the 4x4 dual cab ST-R 9.2L/100km. With plenty of torque on hand, the 4x2 Navara can tow up to 1500kg (braked), while the 4x4 variants are rated to 2800kg (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.
