LPG or Liquefied Petroleum Gas is almost half the price of gas and petrol per liter and should reduce emissions by up to 12 percent compared to petrol. Europe already has more than 32,000 LPG stations spread across its territory. LPG fitted vehicles are dual-mode petrol and gas powered. Switching between petrol and gas modes is simply done by pressing a switch.
The fuel tank is made out of steel and composite materials and the vehicles are equipped with five safety accessories: a non-return valve, an 80 percent tank-fill limiter, fuel flow limiter, a solenoid and a shut off valve. When in LPG mode, studies have shown vehicles are 60 percent quieter than diesel-powered vehicles.
E85 bioethanol is a renewable form of energy, with up to 70 percent lower well-to-wheel CO2 emissions, compared to petrol engines. It has a competitive pump price and it is subject to tax incentives in France, Sweden and the Czech Republic. The fuel will only be available for the 1.6l engine, which is said to have the same performances as the regular petrol powered 1.6 engines.
The 1.2l 16 valve engine will equip both Sandero and Logan models. CO2 emissions for this 75 horsepower engine are 139g of CO2 per kilometer. The 5.9l/100 km fuel consumption is due to the lowered idle speed of the engine. With only 650 rpm, the 1.2l is the first Renault engine to run at such low idle speed.
The Dacia Eco signature can be found an all 5 Dacia models (Logan Sedan, Logan MCV, Logan Pickup, Logan Van and Sandero). CO2 emissions for Logan Sedan and Sandero range from 120g CO2/km for the dCI 70 and dCi 85 engines to 140g CO2/km for 1.2l and 1.4l engine. The E85 CO2 emissions stand at 130g CO2/km.
All three other models (Logan Van, Pickup and MCV) have 140g CO2/km emissions for the dCI 70 engine and 137g CO2/km for the dCI 85 one. The 1.2l and 1.4l GPL-gas engines are still in the process of being homologated.
