Renault R-Type engine

The Renault R-Type is a straight-4 diesel engine produced from 2011. It replaces the 1.9 dCi engine in Renault's range and replaces the 2.0 dCi in the Nissan Qashqai. When launched, the engine produced 130 PS (96 kW; 128 hp) however a higher-powered twin-turbocharged variant producing 160 PS (118 kW; 158 hp) will be introduced later.

R9M 130PS

R9M 130PS was introduced in 2011.

Developed within the framework of the Alliance, the newcomer's performance credentials are similar to those of its predecessor, the 1.9 dCi 130 engine. This 1.6-litre powerplant delivers peak power of 130 PS (96 kW; 128 hp) and generous torque of 320 N⋅m (236 lb⋅ft) available across a broad rev-band.

This new block marks the beginning of a new phase in Renault's engine downsizing policy. The downsizing was obtained thanks to the shortening of the stroke of the pistons and a redesign of the reciprocating parts. The cylinder's swept volume is reduced and thereby diminishes the amount of fuel being burned during each cycle. Performance levels have been maintained, however, by improving turbocharging efficiency.

Applications:

R9M 160PS

R9M 160PS was launched in February 2011.[4] It is twin-turbocharged, derived from the new Energy dCi 130. It produces 160 PS (118 kW; 158 hp) from a capacity of 1.6 L (1,598 cc) – that’s a specific power output of 100.1 PS (73.6 kW; 98.7 hp) per litre. Peak torque 380 N⋅m (280 lb⋅ft) is available from 1,750 rpm. Paired with a dual clutch EDC gearbox, this driveline outputs CO
2 emissions of 99 g (3.5 oz) per kilometre.

Applications:

R9N 120PS

R9N 120PS was launched in 2018

Developed within the framework of the Alliance, the newcomer's performance credentials are similar to those of its predecessor, the 1.9 dCi 130 engine. This 1.7-litre powerplant delivers peak power of 120 PS (88 kW; 118 hp) and generous torque of 300 N⋅m (221 lb⋅ft) available across a broad rev-band.

Applications:

R9N 150PS

R9N 150PS was launched in 2019

This 1.7-litre powerplant delivers peak power of 150 PS (110 kW; 148 hp) and generous torque of 340 N⋅m (251 lb⋅ft) available across a broad rev-band.
