The first Cleartec model is the gasoline-fueled Colt. It's got Stop & Start technology, as well as low-rolling resistance tires (somewhat over inflated) and low-viscosity engine oil. When applied to existing engines like the 1.1 liter 75hp engine, Cleartec reduces CO2 emissions to 115 g/km and consumes fuel at a rate of 4.3 l/100km (55 mpg U.S.). The 1.3-liter 95hp unit gets emissions of 119 g/km and also burns 4.3 l/100km. When flex-fuel capabilities are used, the latter engine increases its fuel consumption to 5 l/100 (47 mpg U.S.) and emissions go up to 143 g/km. Mitsubishi is not applying Cleartec to diesel engines.
