General Motors Europe’s Opel/Vauxhall Corsa is now offered with an updated diesel 95PS 1.3CDTI ecoFLEX start/stop engine which now achieves 85.6mpg while emitting just 88g/km of CO2, a 2.4mpg and a 6g/km improvement over the 2011 model.
“In just five years, from the first Corsa ecoFLEX to today, we have been able to reduce consumption and CO2 emissions by 26%,while at the same time increasing performance by over 26%,” said engineering chief Mike Ableson.
A number of enhancements have been made to reduce consumption and emissions. The turbodiesel is equipped with a variable displacement oil pump that delivers only the necessary oil pressure. It varies oil volume depending on the load in order to reduce the energy needed for oil circulation. The use of special low-viscosity transmission oil also contributes to efficient fuel consumption. These measures are rounded off by an adjustment of engine mapping in the engine control module.
From November 2012 the Corsa will also have a new generation of Opel/Vauxhall-designed manual transmissions with a more precise and smooth gear change action. The base transmission was comprehensively reworked with new gears and modified parts, including the shift rods and fork shaft. The end result is high shift comfort and optimised operation in cold and warm conditions. New 185/65 R15 low rolling resistance tyres also add to efficiency.
Maximum torque of 190Nm is available between 1,750 and 3,250rpm.
