The new Opel/Vauxhall Corsa 1.3 CDTI ecoFLEX is even more efficient than the outgoing version and is now officially the “most economical and fuel efficient diesel model Opel has ever built.” The new 1.3 CDTI ecoFLEX uses a 1.3-litre diesel engine with output of 95 hp and 190 Nm of torque (between 1,750 and 3,250 rev / min), which has been subject to some essential improvements to reduce its thirst for fuel. The four-cylinder engine now consumes 3.3 litres of diesel per 100 km and emits 88 grams of CO2 per kilometer (3.4 l/100 and 89 g / km, for the five-door model), which is 0.2 l/100 km and 6 g / km CO2 less than the previous variant.
Opel/Vauxhall engineers have introduced a variable displacement oil pump, so that the oil is delivered at the required pressure only and varies oil volume according to the load. The oil itself is of a low viscosity type. The engine mapping has to be adjusted accordingly in the engine control unit.
From November 2012, Corsa ecoFLEX will also be equipped with a new manual transmission, revised to ensure a more precise and smooth shifting: fork shaft and shift rods have been modified to reduce friction. The Opel Corsa 1.3 ecoFLEX uses low rolling resistance tyres, measuring 185/65 R15, while suspension and dampen system improve comfort and provide maximum efficiency on the roughest road surfaces. The new version allows accelerating from 0 to 100 km / h in 12.3 seconds and reaching a top speed of 177 km / h.
