Researcher Claims Real-World Economy and Lab Testing Are Miles Apart

One of my guiltiest of pleasures is telling anyone trapped with me in a confined space for more than thirty seconds that practical fuel economy hasn’t improved in a meaningful way since 2014. While the EPA has raised corporate economy estimates, consumer spending has skewed toward larger and less economical models — invalidating the technological gains made in a vehicular catch-22.

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.

Quote Of The Day: The Politics Of Limitless Speed Edition

Deutsche Straßen sind nicht der Nürburgring.

But there I go, quoting German Minister of Transportation Peter Ramsauer out of context, and in the original. Herr Ramsauer’s rebuke comes on news of a late-night crash involving a future Mercedes ML Class prototype, that resulted in the death of a 26-year old man over the weekend. The crash took place on a stretch of non-speed-limited autobahn between Singen and Stuttgart, favored by Mercedes and Porsche for high-speed testing. Apparently the victim had been involved in a minor accident and was trying to exit his vehicle (stalled in the left lane, according to Der Spiegel) when the Mercedes test mule slammed into his car, killing him instantly. The 52-year old test driver is under investigation for negligent homicide.

The Problem With Start-Stop Systems

For an industry under ever-increasing pressure from government emissions standards, start-stop technology (which shuts off engines under idling conditions) seems like an easy route to improved fuel efficiency. Cheaper and less complicated than a true hybrid system, a number of automakers from BMW to Kia are proliferating start-stop technology across their product lines without hybrid-like price premium. Since this technology represents a relatively easy, incremental efficiency upgrade, we’ve wondered why it hasn’t been made available stateside, where hybrids are making up a growing proportion of sales. Detroit’s executives seem to think it’s a good idea, and Mazda has even gone so far as to complain that EPA test results refusing to show the Japanese test-cycle’s 7-9 percent improvement is the main factor preventing it from bringing more stop-start equipped vehicles to the US. But there’s another issue preventing stop-start from becoming standard issue industry-wide, and it’s actually remarkably obvious.

  • Ajla When the Gladiator was introduced FCA said engine cooling is why they didn't use offer the 2.0T and why the Ecodiesel had a lower tow rating than the 3.6L. I'm interested if they actually solved that here or if we'll see the 4xe given a considerably lower tow rating.
