The R-Type is a family of straight-4 turbocharged diesel engines developed by both Nissan and Renault, and also Daimler in regarding the R9M/OM626 engine. Released in 2011, it replaced the 1.9 dCi engine in Renault's range and the 2.0 dCi in the Nissan Qashqai, and in 2015, it also replaced the 2.0 dCi in the Renault Mégane as well. When launched, the engine produced 130 PS. Renault later introduced a higher-powered twin-turbocharged variant producing 160 PS.

R9M
{{anchor|R9M 130|R9M 130PS}}R9M 130
R9M 130PS was introduced in 2011.
Developed within the framework of the Alliance, the newcomer's performance credentials were made similar to those of its predecessor, the 1.9 dCi 130 engine. This 1.6-litre power plant delivered peak power of 130 PS and torque of 320 Nm available across a broad rev-band.
This new block came with a change in Renault's engine downsizing policy. More downsizing was to be obtained, thanks to the shortening of the stroke of the pistons and a redesign of the reciprocating parts. The cylinder's swept volume was reduced and thereby diminished the amount of fuel being burned during each cycle. Performance levels were maintained, however, by improving turbocharging efficiency.
Applications:
- 2011 - Renault Scénic
- 2011 - Nissan Qashqai
- 2012 - Renault Mégane
- 2013 - Renault Fluence
- 2014 - Mercedes Vito
- 2014 - Mercedes C Class
- 2015 - Renault Kadjar
- 2016 - Renault Talisman
{{anchor|R9M 160|R9M 160PS}}R9M 160
R9M 160 was launched in February 2011. It is twin-turbocharged, derived from the new Energy dCi 130. It produces 160 PS from a capacity of 1598 cc – a specific power output of {{#expr:160/1.598 round 1}} PS per liter. Peak torque 380 Nm is available from 1,750 rpm. Paired with a dual clutch EDC gearbox, this driveline outputs emissions of 99 g per kilometre.
Applications:
- 2011 - Renault Captur Concept Car
- 2015 - Renault Espace
- 2016 - Renault Scenic
- 2015 - Renault Talisman
R9N 120
R9N 120 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 and torque of 300 Nm available across a broad rev-band.
Applications:
- 2018 - Renault Scénic
- 2018 - Renault Talisman
R9N 150
R9N 150 was launched in 2019
This 1.75 L (commonly referred to as a 1.7 litre engine) 4-cylinder 16-valve Diesel engine delivers peak power of 150 PS and torque of 340 Nm available across a broad rev-band. This engine was discontinued in 2021 alongside all other diesel engines in the cars of the Renault-Nissan alliance as part of their plan to stop developing and selling new diesel engines in their cars by 2021 in favor of hybrids and EVs.
Applications:
- 2018–2021 Renault Mégane
- 2018–2021 Renault Kadjar
- 2018–2021 Renault Talisman
- 2019–2021 Nissan Qashqai
- 2019–2021 Nissan X-Trail (Europe)
