Renault’s engineers took full advantage of the new threecylinder engine architecture (see box below) to achieve an optimum air-fuel ratio on the Energy TCe 90 unit, even at peak power (from 2,000 to 4,000rpm), in order to bring down fuel consumption in all driving conditions.
The result is a 25 per cent reduction in NEDC combined cycle fuel consumption and CO2 emissions compared to the engine it replaces.
User cost is reduced : between -20% to -50%, depending on countries' tax incentives. With the Energy TCe 90 engine, the driver is spending less on petrol and pays less taxes linked to CO2 emissions (depending on countries) : -1l /100km, -30g of CO2/km * compared to the previous engine. In some cases, he will pay less taxes linked to the engine's cylinders (Germany, Portugal, Romania…)
* : Homologated consumption and CO2 emissions.
