CO2 emissions and fuel economy will be measured in real driving conditions, with segments to include urban, extra-urban and highway driving. As well as devising the testing methodology, T&E may also supervise the tests, which will be carried out by PSA. The results will be independently audited with T&E’s participation and the organisation will withdraw from the project if it is not satisfied with the methodology, testing or validation of results.
T&E director Jos Dings said: ‘Real-world measurements of CO2 emissions and fuel economy will help drivers choose the most efficient models benefiting consumers, public health and the environment. We are confident that the work we plan to undertake with PSA can generate transparent robust results that everyone can rely on.’
The test will take account of higher emissions when the engine is cold and will be performed with lights and air conditioning on. The cars being tested will use standard tyres and lubricants and be prepared as detailed in the owner’s manual. T&E says it will not endorse the cars or the company – only the CO2 data that will be published. It will not receive any payment for its participation.
