Renault Laguna Diesels Become Cleaner and More Frugal

It’s not exactly the coolest car on the road, but the Renault Laguna could prove to be an excellent choice for both the family man and the business owner looking to stock up on a fleet of eco-minded vehicles. This is especially true since the CO2 emissions and fuel consumption of the diesel range have been slashed.

With 85 percent of the cars sold being diesel-powered, Renault looks set to become a green carmaker without having to focus on hybrid tech.

The Laguna powered by the dCi 110 engine is the base case in point, with CO2 emissions of 109g CO2/km, thanks notably to the incorporation of deceleration/braking energy recovery. In addition, the Energy range of engines has been extended with the 2.0 dCi units borrowing tech from the new Energy dCi 130: Stop&Start, deceleration/braking energy recovery, thermal management technology and variable displacement oil pump. Thus, Laguna models equipped with those engines reduce their CO2 emissions by approximately 15 percent, claiming a record of 118g/km.

It’s the same picture when you take a look at the fuel economy battle:

• Lagunas powered by the 2.0 Energy 130 or 150 diesel engines: 4.5 liters/100km
• Lagunas powered by the dCi 110 diesel engine: 4.2 liters/100 km (equivalent to a range of more than 1,500km!)

That might not sound all that impressive, but it means that you can complete the journey from Paris to Marseille on just one full tank of diesel. 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 which will notably incorporate deceleration/braking energy recovery (ESM).
