REDUCING FUEL CONSUMPTION

One of the main objectives for Renault engineers is reducing emissions of CO2, the main greenhouse gas, by reducing fuel consumption. The Group’s longstanding efforts in this area place it in today's top three carmakers on low fuel consumption and CO2 emissions.

Optimizing vehicle  

Because vehicle design influences fuel consumption, Renault seeks to optimize all its vehicle bodies for better fuel economy.  

 

Making a vehicle more aerodynamic reduces drag, which calls for less effort from the engine and thus cuts fuel consumption.

 

Lighter cars also consume less fuel. This is why Renault engineers strive to reduce vehicle mass.

 

Renault develops technologies to minimize friction and rolling resistance to improve the overall efficiency of its vehicles.

Optimizing engines  

Renault also works on engines and gearboxes to reduce the fuel consumption and CO2 emissions of its vehicles.

 

The engine management unit is used to optimize engine efficiency while bringing a significant reduction in greenhouse gas emissions.

 

The camshaft angle variator also limits fuel consumption and emissions, by optimizing engine performance according to speed.

 

In the longer term, the stratified-charge petrol engine will bring a near 40% reduction in fuel consumption by optimizing spray strategy.

Continue implementing alternative energies 

Fuel consumption and CO2 emissions will also be reduced by exploring alternative energy sources such as biofuels, electric motors and fuel cells. These energies are, or will be, gradually being rolled out across the Renault range according to geographical criteria and type of technologies.
