Volkswagen has adjusted carbon dioxide emissions ratings for many of its cars following on from the emissions scandal, but one leading academic has defended the move saying it’s a “normal process for car companies to refine CO2 numbers” .
Models such as the Polo, Golf, Passat and Touareg are included in the changes, which come in the wake of the the recent record settlement of $14.7 billion (£12 billion) in the USA for vehicles affected by the 2015 emissions scandal.
A company spokesman said: “In the interests of providing our customers with stated fuel consumption figures that are even closer to real-world driving, Volkswagen has voluntarily made slight adjustments within internal parameters for the NEDC homologation test. As a result of this, minor modifications have been made to the brochure data for some model variants going forwards.
“These changes have no impact on customers’ actual real-world consumption figures.”
The biggest alteration noted by Autocar’s data experts is the Golf 1.6 TDI with manual gearbox. It’s been updated from 99g/km to 103g/km. A Polo 1.0 MPI 60’s CO2 emissions are now rated at 108g/km where they were previously 106g/km.
