New CO2 figures for the updated Toyota Prius have pushed the car out of the London Congestion Charge exemption zone, which dictates that cars must produce less than an average of 75g/km CO2 in order to enter the area free of charge.

A Transport for London (TfL) spokesman confirmed to Autocar that it won"t be re-evaluating existing cars, however, so the Prius, which is now listed as producing 78g/km of CO2 according to Europe"s latest emissions testing procedure, will keep its free pass into the capital"s Congestion Charge zone even in its latest form.

The adjusted numbers are a result of changes to the New European Driving Cycle (NEDC) test. European regulators are now using this evolved process that adopts some parts of the Worldwide Harmonised Light Vehicle Test Procedure (WLTP), which will come fully into force next year.

New WLTP and RDE fuel economy and emissions tests explained

It"s a tougher test, therefore it has edged the Prius range"s official CO2 output to 78g/km for the most efficient variant on 15in wheels, representing an increase of 5g/km. Models equipped with 17in wheels now have CO2 emissions of 82g/km, up from 76g/km.
