 It is responsive from low revs, flexible and has power in reserve while displaying the lowest fuel consumption figures for a petrol engine.It emits only 137 g/Km of CO2 on Clio 3 and 140 g/km of CO2 on Modus and the Twingo GT.These unique qualities are obtained thanks to the combination of a 1.2L capacity engine with a low inertia low boost pressure turbocharger whose response time is reduced to the minimum, through the use of a turbine and a small diameter compressor.
