The 1.5-litre dCi diesel engine in the Nissan Juke has been revised to offer lower emissions, greater fuel economy, more torque and reduced noise. It’s on sale now for the same price as the old model.
The revisions see maximum torque increase from 240Nm to 260Nm at 1,750rpm, with 80 percent of maximum torque available from 1,500rpm.
CO2 emissions drop from 124 g/km to 109 g/km, which allows the Nissan Juke 1.5 dCi to drop from VED Band D (£105 pa) to Band B (£20 pa).
Economy is also improved, with 67.3 mpg recorded on the combined cycle, up from 58.9 mpg.
These changes have been achieved by revisions to the piezo-electric fuel injection nozzles to allow a more precise spray pattern, and a new low-inertia variable geometry turbocharger with a more direct air intake path.
A closed-loop low-pressure exhaust gas recycling (EGR) system helps the new engine comply with the forthcoming Euro6 emissions standard.
To reduce internal friction, the engine uses diamond-like carbon (DLC) coatings for the tappets, as well as a thermostatically controlled variable displacement oil pump.
There are also revisions to the gear ratios: 1st and 2nd gears are now a little shorter to sharpen low-speed response, while 3rd gear and above are now slightly longer.
The Juke now also features Nissan’s Start/Stop system – which turns off the engine when the vehicle is waiting in traffic and restarts it within 0.5 sec of the clutch pedal being depressed – as standard.
Nissan’s Dynamic Control system, which allows the driver to select from three throttle response settings – Eco, Normal and Sport – is now also standard. In Eco mode, engine torque is limited to 220Nm.
Despite these changes, the engine’s peak power remains at 110PS, and the 109mph top speed and 11.2 sec 0-62mph time are also unchanged.
The new Nissan Juke 1.5 dCi is on sale now, priced from £14,895.
