suzu Australia Limited has introduced a comprehensive
upgrade for its all-important N Series, bringing fresh looks,
increased performance on NPR variants and a new electric
stability control system to the light-duty truck range.
The 2015 update also heralds a change in nomenclature for
the massive 50-plus model range, with the familiar three-letter
model codes remaining – NLR, NLS, NNR, NPR, NQR and NPS
– but then followed by two numbers that reflect GVM rating
(from 4.5t to 8.7t, expressed 45, 87, etc) and a separate number
indicating power rating in PS (or metric horsepower).
By way of example, and an illustration of the improved
performance, the NPR 65-190 and NPR 75-190 – with 6.5t
and 7.5t GVM respectively – now benefit from the high-output
190PS (or 140kW) powertrain previously restricted to the
higher-series NQR line.
This is the ‘4HK1’ SiTEC Series III 185 engine – a 5.2L turbo-
diesel that develops its maximum power at 2,600rpm and
carries 510Nm of torque available from 1,600-2,600rpm. This
equates to a 23% increase in power and 22% torque boost
compared to the previous SiTEC 155.
It combines with a six-speed manual gearbox, complete
with full synchromesh on all forward gears, while a six-
speed automated manual transmission (AMT) with both fully
automatic and clutch-less manual modes is available.
The 190PS engine is also now offered in the driver’s licence
category NPR 45-190, the strong performance combining with
a 2t payload when fitted with an aluminium tray – a package
especially designed to appeal to tradespeople who might
otherwise be looking for a diesel utility.
The 2015 N Series is identified by fresh new looks, including
revised grille design in paint colour for NLR, NLS, NNR and
NPS, and chrome on NPR and NQR variants. The latter also
benefit from the ‘premium’ specification level, picking up fog
lamps and automatic climate-control air conditioning (except
for Tipper variants).
New seat trim and a smaller steering wheel are now included,
and the driver’s seat comes with a vibration-absorbing support
pad, torsion bar and optimised weight ratio for up to 130kg.
Among other changes to the range, all N Series models bar
the NQR have a new 90A alternator (up 10A) that broadens
its ability to handle aftermarket accessories, while greater
data capacity comes with more information from CAN BUS
stored onboard. Isuzu says the latter is important in enabling
technicians to “readily access more operational data to
diagnose and rectify any issues that may occur”.
NNR and NPR 45 and 55 models now have the ‘MYY6’
transmission with revised ratio set. Third and fourth gear
ratios have been revised, effectively narrowing the gap from
second to third gear.
A new Isuzu Electronic Stability Control (IESC) system applies
to all NLR, NNR and NPR models, constantly monitoring data
from a range of sensors to detect and, if required, help correct
an unexpected loss of vehicle control. It works in conjunction
with a raft of other safety equipment including traction control,
hill-start assist and ABS brakes with EBD.
