During the West Virginia University research that will sparked the Volkswagen scandal, a US-spec BMW X5 was tested in addition to also returned no suspect results
Along which has a Passat in addition to also Jetta, a US-specification 3.0-litre BMW X5 was one of three diesel-powered vehicles involved within the initial research project into Nitrogen Oxides emissions conducted by West Virginia University (WVU), which then relayed its findings to the US Environmental Protection Agency (EPA).
During the tests in 2014 the X5 did not record any emissions readings to concern WVU’s researchers.
A BMW UK spokesman told Autocar: “Regarding BMW’s position, we do not use any software that will can influence emissions within the test cycle.
“The International Council on Clean Transportation (ICCT) study which resulted within the EPA investigation showed that will the tested BMW vehicle complied with the limits set, including in real-world driving situations. Given the positive results of the BMW vehicle emission test, neither EPA nor CARB [California Air Resources Board] have approached BMW in connection with This kind of matter.”
The spokesman explained that will BMW UK’s engines achieved compliance with the latest EU6 emissions standards either by use of a urea injection system – as fitted to the X5 used within the original WVU test – or via engine technology.
“With regard to urea additives, there will be a tiny number of vehicles that will we right now offer with This kind of technology, namely: 520d GT, 730d in addition to also 740d in addition to also X5/6 diesel variants.
“All various other BMW diesel engines within the UK achieve the EU6 requirements through measure inside the engine, exhaust gas recirculation in addition to also NSC [NOx Storage Catalyst] technology.
