Modus 1.5 dCi 105 Features All-New Six-Speed Manual Gearbox
Renault has launched a new powertrain for Modus. The 1.5 dCi diesel engine now develops 106hp (78kW) and is teamed with an all-new six-speed manual gearbox. The third Alliance powertrain, the gearbox was jointly developed by Renault and Nissan engineers. It features all the latest technological innovations: piezo-electric injectors, multi-injection, special piston geometry and a twin-mass damping flywheel.
Boasting excellent driveability, the engine meets Euro 4 emission standards. The new powertrain is available with the Confort Pack Clim (Expression and Dynamique trim), Luxe (Dynamique and Privilège trim) and Initiale equipment levels. Modus is now powered by a 1.5 dCi 105 diesel engine coupled with a new six-speed manual gearbox developed jointly by Renault and Nissan.
The new engine brings further improvements to the 100hp 1.5 dCi diesel from which it is derived, with power up from 100hp (74kW) to 106hp (78kW) at 4000rpm, and torque up by 20%, from 200Nm to 240Nm at 2000rpm.
Performance rises accordingly, with a racetrack top speed of 186kph and acceleration from standstill to 100kph in 11.2 seconds. This version of the 1.5 dCi engine carries over all the technologies that made the 100hp version so successful (second-generation common rail, multi-vane variable-nozzle turbocharger, 1600 bar injection pressure) and adds a few more. The solenoid injectors on the 100hp version give way to six-hole piezo-electric injectors on the new unit.
Siemens piezo-electric technologymakes multi-injection a viable proposition: with the tuning adopted, the response of the new injectors (four times quicker than a solenoid injector) is fast enough for three injections per cycle: pilot, main and post. With dosing even more precise than before, the pilot injection stage improves acoustics by minimizing the diesel clatter effect, especially at idle speed. The post-injection stage helps cut down on pollutant emissions by burning off the soot produced during combustion. The new engine thus achieves benchmark fuel consumption and pollutant emission performance for this vehicle category: 124g of CO2/km in a combined cycle on Modus.
Another major upgrade concerns piston geometry, which also contributes to compliance with the Euro 4 emission standards. Vehicle acoustics are further improved by using a twin-mass damping flywheel, which cuts out booming noise at low engine speeds. Noise is further reduced by the specially developed wide-faced cylinder block and fourth powertrain mounting point. And multi-injection technology (with the pilot injection stage in particular) cuts down combustion noise.
The 1.5 dCi 105 engine is assembled at the Renault plant in Valladolid, Spain.
