YD25 2.5 litre turbocharged diesel engine, shown during Navara unveil in Thailand, will be taken to markets with fuel grades below Euro 4, including Malaysia. YD25 engine is the replacement for engine in current model of Nisan Navara, with enhancement in cylinder head, thereby improving fuel economy by about 11% (as claimed by Nissan).
Said engine will be offered in two tunes, a 160 hp, 403 Nm low end version and 188 hp, 450 Nm high end model. This will be available in aforementioned sub Euro 4 fuel grade markets. But, new 2.3 litre YS23 engine will not reach Malaysian shores. Latter engine is derived from 2.3 dCi mill seen in Renault Master van, reserved for markets with Euro 5 fuel.
New 2.3 litre YS23 motor will also be offered in two power specs, a 158 hp, 403 Nm lower tune variant with single turbocharger and 188 hp, 450 Nm (similar to YD25) high tune model with twin turbo. Though YS23 has less displacement compared to YD25, the two stage turbocharger helps peak torque kick in earlier between 1,500 – 2,000, as opposed to single peak point at 2,000 rpm in YD25 engine.
Mileage of YS23 engine is claimed to be improved by 19% compared to outgoing YD25 engine. This is achieved through electrical variable oil pump, thermo management system and reduced engine friction in new YS23 engine.
Jatco seven speed auto transmission would be standard in all markets where Nissan Navara NP300 will be sold. Six speed manual transmission will also be available, featuring wider gear ratios than in existing Navara pickup.
Further, Nissan Navara NP300 will feature five-link rear suspension with coil springs in place of leaf springs usually seen in pickups. This ensures better handling and ride quality than those with conventional suspension setup. The move suggests a Navara based SUV would be considered in future, rivalling Toyota Fortuner, Mitsubishi Pajero Sport and such. As far as Malaysia is concerned, new Nissan Navara pickup will better compete with Ssangyong Actyon, which also sports multi link rear suspension.
