An economic assessment conducted by the International Council on Clean Transportation found that, due to recent improvements in technology, the Environmental Protection Agency’s rationale for its 2025 fuel efficiency standards may have overestimated the cost for automakers to comply. The ICCT’s study shows average per-car investments 34 to 40 percent lower than the previous EPA appraisal.

While this information, had it come out sooner, may not have kept automotive executives from bending the president’s ear to reevaluate EPA guidelines, it certainly reframes their reasons for doing so. The ICCT, famous for turning researchers loose on Volkswagen diesels, makes a good case that manufacturers have the tools to meet current standards without spending a lot of money.

A German environmental group said Tuesday that its testing has revealed Renault’s Espace, when equipped with a 1.6-liter diesel engine, could emit up to 25 times the allowable limit of nitrogen oxides with a warm engine running on roads — or you know, the real world.

According to the New York Times, the Deutsche Umwelthilfe (DUH) didn’t directly accuse Renault of including cheating software in its cars — a la Volkswagen — but said the van polluted significantly less when the engine was cold. The results could show the schism between European testing standards — where tires can be over-inflated, doors taped up, batteries disconnected, seats removed — and real-world conditions.

Renault said in a statement Tuesday that its van complied with regulations and that tests done by researchers at the University of Bern “are not all compliant with European regulations.”

Is clean diesel the cleanest diesel in the tub? Not as previously hoped, according to a new report.
