The Renault-Nissan MR engine family consists of straight-four 16-valve all-aluminium and water cooled automobile engines with variable valve timing co-developed by Renault and Nissan. Renault calls it the M engine. Other noteworthy features of this engine family include acoustically equal runner lengths and a tumble control valve for the intake manifold, a "silent" timing chain, mirror finished crankshaft and camshaft journals, and offset cylinder placement in an attempt for increased efficiency.

The MR engine family features 'under stress' manufacture, meaning while the block is being bored, a torque plate puts the block under stress. The block becomes temporarily distorted until the head is torqued onto it, at which point the block is pulled into the correct shape.

MR16DDT (Renault M5Mt)

The MR16DDT is a {{convert|1618|cc|L|1|abbr=on|comma=5|order=flip}} DIG-T (Direct Injection Gasoline-Turbocharged) inline-four 16-valve engine, with a bore x stroke of {{convert|79.7x81.1|mm|2|abbr=on}}. It was first introduced in the Nissan Juke small SUV in the autumn of 2010. Output is {{cvt|190|PS|kW hp|0|disp=flip}} and {{cvt|240|Nm|lbft|0}} of torque. The 2014 Juke NISMO RS FWD produced {{cvt|215|PS|kW hp|0|disp=flip}} and {{cvt|285|Nm|lbft|0}}. In 2015, the Nissan Teana received this 1.6 Turbo as a replacement for the earlier 2.0-liter naturally aspirated engine. In 2013, it entered Renault's lineup in the Sport Clio as the M5Mt, where it generates {{cvt|200|PS|kW hp|0|disp=flip}} and {{cvt|177|lbft|Nm|0|disp=flip}}.

The MR20DE, a {{convert|1997|cc|L|1|abbr=on|comma=5|order=flip}} engine, was the first MR series engine developed by Nissan as a replacement for the QR20DE. It is an undersquare engine, its bore and stroke being {{convert|84x90.1|mm|in|2|abbr=on}}, respectively. It was first introduced in the Lafesta and Serena MPVs and Renault Samsung SM5 in early 2005. In November 2006, it entered Renault's lineup in the Clio III as the M4R, where it generates {{cvt|147|PS|kW hp|0|disp=flip}}.

This engine is available with Nissan's XTRONIC CVT continuously variable transmission in several applications.

A detuned version, with {{cvt|133|PS|kW hp|0|disp=flip}} instead of {{cvt|147|PS|kW hp|0|disp=flip}}, was added to the new Bluebird Sylphy in late 2006. In the new Nissan X-Trail, Qashqai and C-Platform Sentra, the MR20DE produces {{cvt|147|PS|kW hp|0|disp=flip}} at 5100 rpm and {{cvt|199|Nm|lbft|0}} of torque at 4800 rpm. Middle East version of the MR20DE engine that goes in the Nissan Qashqai produces {{cvt|150|PS|kW hp|0||disp=flip}} at 5200 rpm and {{cvt|200|Nm|lbft|0}} of torque at 4400 rpm.

M9 diesel

The M9R and M9T are a family of straight-four 16-valve turbocharged diesel engines co-developed by Nissan and Renault, and also Mercedes-Benz Group in the case of the M9T/OM699. Following Renault's designation plan, the last letter (M9R resp. M9T) is to indicate the swept volume of 2.0 L resp. 2.3 litres. Despite the similar names, the diesel engines are only loosely related to the MR gasoline engines. M9R is built at Renault's Cleon factory in Normandy.{{Cite web|url=https://www.renaultgroup.com/groupe/implantations/usine-cleon/|title=Usine de Cléon - Renault Group|website=www.renaultgroup.com|accessdate=6 January 2024}} As of late 2018, a new version of the M9R using adBlue and with slightly different internal dimensions replaced the original M9R.

Features of the diesel engines include a cast-iron block, aluminium alloy cylinder head with double overhead camshafts, 16-valve layout and a bushes timing chain. The M9T is directed to heavier vehicles like the Nissan Navara or the Renault Master. It features a bore and stroke of {{cvt|85x101.3|mm|2}} for a total displacement of {{convert|2299|cc|L|1|abbr=on}}, balancer shafts,[http://www.powertrain.renault.com/application/storage/upload/filemanager/brochure/brochure_engine_new/Brochure_2000_dCi_MAJ_2014.pdf Brochure] renault.com {{Dead link|date=March 2023 |bot=InternetArchiveBot |fix-attempted=yes }} typical speeds are 3500 rpm for maximum power and 1250 rpm for maximum torque.

Low output versions of the M9R for the Renault Trafic II at {{convert|66|and|85|kW|PS hp|0|abbr=on}} had been replaced by the Renault R engine with the introduction of the Trafic III, while versions starting from {{convert|96|kW|PS hp|0|abbr=on}} include VNT chargers. The top version of the Navara utilizes the M9T with twin-turbochargers and {{cvt|190|PS|kW hp|0}}. During production period engines had been updated up to Euro 6 (in early 2017).

The M9R is a {{convert|1995|cc|L|1|abbr=on|comma=5|order=flip}} 16-valve turbocharged diesel engine developed by the Renault–Nissan Alliance, and first installed in the Renault Laguna in 2006. It is available in the {{convert|150|PS|kW hp|0|abbr=on}} tune in Nissan Qashqai, Nissan X-Trail, Renault Mégane, Renault Koleos and Renault Laguna models. In this trim the engine achieves maximum power at 4000 rpm and maximum torque of {{convert|340|Nm|lbft|0|abbr=on}} at 2000 rpm. A {{convert|175|PS|kW hp|0|abbr=on}} form with particulate filter is available in Renault Laguna and Nissan X-Trail models. A {{convert|180|PS|kW hp|0|abbr=on}} variant is also available on the Laguna GT. In both engines maximum power is achieved at 3750 rpm and maximum torque is available from 1750 rpm.

In order to reduce vibrations, balance shafts are included in some versions of the engine.

The 2.0 dCi engine in all its versions complies with the Euro 4 and 5 standards for exhaust emissions. The {{convert|150|PS|kW hp|0|abbr=on}} New Mégane and New Laguna respectively emitted {{convert|144|g|abbr=on}}/km and {{convert|154|g|abbr=on}}/km of CO2 and the {{convert|129|kW|PS hp|0|abbr=on}} version of New Laguna 2.0 dCi emits {{convert|159|g|abbr=on}}/km of CO2; they all comply with the Euro 5 standards for exhaust emissions.

In 2011 the {{convert|96|and|110|kW|PS hp|0|abbr=on}} M9R engines has been updated with an optional package to lower exhaust emissions (Euro5) and fuel consumption. These engines are tagged "2.0 Energy dCi 130" resp. "2.0 Energy dCi 150", typically maximum power is available at 3750 rpm and maximum torque at a minimum of 1750 rpm. The package comprises:

  • Stop & Start
  • Active thermal management
  • Smart electrical management
  • Variable capacity oil pump

The CO2 values were thus reduced to 118 g/km for the Laguna both the 2.0 Energy dCi 130 and 2.0 Energy dCi 150.

Towards the end of 2018, the 2-liter M9R engine became the "M9R Gen 5" when it received a thorough redesign to comply with the increasingly stringent anti-pollution regulations: first of all the engine dimensions were changed, from {{cvt|84x90|mm|2}} to {{cvt|85x88|mm|2}} - using the same bore as the larger M9T but with nearly no change in displacement, which increases by 2 cc to 1997 cc. Another important innovation introduced with this update was the BluedCi technology, which involves the installation of a small tank of adBlue, a chemical additive that is injected upstream of the catalyst and which, when combined with the exhaust gas, causes a reaction chemistry within the catalyst itself. This reaction transforms most of the nitrogen oxides into harmless nitrogen and water vapor. This engine debuted in two power levels, {{cvt|160|and|200|PS|kW hp|0}}, in the Renault Talisman II 2.0 Blue dCi which was produced from December 2018. In December 2020 a single 190 PS version replaced both of the earlier versions.

The engine is fitted to the following vehicles:
