Significantly reduced CO2 emissions for Renault Laguna


The CO2 emissions and fuel consumption of diesel versions of Renault Laguna have been slashed. These versions have so far accounted for 85 percent of the model’s sales in 2011.The diesel engines of the Laguna range (dCi 110, dCi 130 and dCi 150) are poised to evolve in September 2011 with the introduction of new technologies.

Versions of Laguna powered by the dCi 110 engine will feature world-best CO2 emissions of 109g CO2/km, thanks notably to the incorporation of deceleration/braking energy recovery.



The Energy line-up of engines gets wider with the 2.0 dCi engines (130 and 150hp), featuring the same technologies as the new Energy dCi 130: Stop&Start, deceleration/braking energy recovery, thermal management technology and variable displacement oil pump. Lagunas equipped with those engines reduce their CO2 emissions by approximately 15 percent, claiming a record of 118g/km.

· Fuel consumption follows the same downward trend:

- Lagunas powered by the 2.0 Energy 130 or 150 diesel engines: 4.5 litres/100km
- Lagunas powered by the dCi 110 diesel engine: 4.2 litres/100 km (equivalent to a range of more than 1,500km!). It will be possible to complete a return journey from Paris to Marseille on a full tank.

A new Energy powerplant for the Renault Laguna range

The M9R 2.0 dCi diesel engine available for Renault Laguna will feature Stop&Start technology and deceleration/braking energy recovery (Energy Smart Management, or ESM for short) from September 2011. The introduction of these technologies will enable it to be included in the Energy line-up of engines.

Renault Lagunas equipped with the 2.0 Energy dCi 130 or 2.0 Energy dCi 150 engines will claim CO2 emissions of just 118g/km (down 18g/km) or 120g/km (down 16g/km) for the saloon and estate versions respectively.

Those two engines (130hp and 150hp) will also see the fuel consumption of 2.0 Energy dCi saloon and estate versions fall to 4.5 litres/100km (a saving of 0.7 litres/100km) or 4.6 litres/100km (a saving of 0.6 litres/100km) respectively.

109g of CO2/km for Laguna’s dCi 110 engine

In addition to the 2.0 Energy dCi 130/150 engines, the Laguna range will also see the introduction of a new 1.5 dCi engine (Type K9K) which will notably incorporate deceleration/braking energy recovery (ESM).

With this new engine under the bonnet, Renault Laguna will return low CO2 emissions of just 109g/km or 110g/km for the saloon and estate versions respectively.

In France, in 2011, these two engines will permit customers to benefit from a state subsidy of €400 at the time of purchase.

Meanwhile, fuel consumption of 4.2 litres/100km equates to a range of more than 1,500km on a full tank and represents a saving of approximately 10 percent compared with the previous-generation engine.
