‘Test gaming will continue to undermine CO2 cuts after 2020’

While new cars sold in 2014 averaged CO2 emissions of 123g/km, according to the How Cleans are Europe's cars 2015? report, real-world emissions are much higher and reductions in CO2 are happening considerably slower than depicted. Now T&E is warning that the cheating will continue to undermine progress even after a new test, the Worldwide harmonized Light vehicles Test Procedures (WLTP), is introduced.

First real-world car CO2 results show gap of up to 56%

The very first tests of cars’ ‘real-world’ CO2 emissions have revealed gaps between official and actual emissions of 36-56% – very similar to those of other on-road fuel efficiency databases. Three models were tested by PSA Peugeot Citroën, under a protocol devised with T&E, on public roads near Paris with passengers, luggage loads, use of air conditioning and other real-life driving conditions.

Electric car ‘hatchet job’ debunked

A study claiming that electric vehicle produce more carbon emissions than a diesel car has been promptly debunked by academics and experts in Germany, where it was published last month. The Institute for Economic Research (Ifo) was roundly criticised over its findings which were founded on a relatively high weighting of coal generation in Germany’s power mix.

Watch out for fake EVs, national regulators told

Carmakers can exploit loopholes in the EU’s new CO2 emissions targets to push sales of fake plug-in hybrid cars over EVs with no tailpipe emissions, T&E has warned. The law credits manufacturers for selling EVs but leaves room for gaming. This could allow carmakers to supply half of all the ´zero and low-emission’ cars needed to comply with stricter CO2 limits with fake ‘electric’ cars.

Court to test allegations of a new VW diesel scandal

A German television company has unearthed documentation that suggests Volkswagen is involved in a new ‘Dieselgate’ scandal. The documents allegedly show that VW has put software in the Euro 6 engine series which replaced the Dieselgate Euro 5 engine series found to have manipulated emissions. VW denies the claim. The allegations came as T&E published data on the fourth anniversary of Dieselgate which shows the number of dirty diesels is reaching record levels on Europe’s roads.

Evidence of carmakers manipulating new test to cheat CO2 targets – Commission

Carmakers are manipulating the results of a new test for CO2 emissions, evidence uncovered by the European Commission indicates. The new lab-based WLTP test was supposed to fix the testing problems that in the past allowed manufacturers to cheat EU emissions targets. But Commission documents indicate the industry is manipulating the new test results to inflate the CO2/fuel economy results of its vehicles. This will reduce the stringency of the EU’s proposed 2025 CO2 targets by more than half.

Collusion to weaken fuel economy regulations

The current system for testing car CO2 emissions and fuel economy, the NEDC, is obsolete. Thankfully, a new test, the WLTP, is scheduled to replace the NEDC in 2017. To do this, the average CO2 emissions target for cars (95 g/km for 2020/1) needs to be revised in a way that maintains “equivalent stringency” between the tests.
