Renault-owned budget brand Dacia is launching a new factory-fitted dual-fuel option across its Sander, Sandero Stepway, Logan MCV and Logan MCV Stepway models and says it is the only manufacturer in the UK to do so. The 1.0-litre turbo Bi-Fuel 100 engine combines petrol and LPG fuel to deliver reduced fuel costs, lower emissions and improved performance without compromising on quality, Dacia claims.
