However, some researchers have also begun calling the technologies focused on cutting emissions and saving fuel into question. We already know that lab tests can be gamed through clever engineering. But we don’t drive vehicles on a rolling road and the differences between the lab and the street are immense. Emissions Analytics, an independent company based in the United Kingdom, has tested more than 500 vehicles in the United States since 2013 and believes a change in testing venue can make all the difference.

The firm conducts real-world analyses under normal on-road driving conditions using portable testing gear. Its says its goal is to suss out which trends in the automotive space actually have a meaningful impact on economy — and which are bunk.  (Read More…)
