Vehicle Testing

With the exception of California's longstanding ability to set its own tougher emission standards, any car legal to sell in one state of the U.S. is legal to sell in all of them. And aside from a handful of differences—daytime running lights, speedometers marked in km/h—Canadian-market...

Jaguar’s upcoming first entry into electric vehicles is undergoing final validation in Los Angeles, a year after the British brand revealed the I-Pace Concept at the 2016 Los Angeles Auto Show. Jaguar wrapped the new I-Pace in a pseudo-mule livery and plastered a hashtag on its side as...

Diesel-powered cars have enjoyed a comfortable market share in Europe for decades, but their decline in popularity continues following numerous diesel-emission cheating scandals and regulatory crackdowns. As if diesel cars hadn't already had enough negative press, a new study says "fuel-efficient"...

Fuel-economy ratings for cars sold in Europe have long been wildly unrealistic, sometimes more than 30 percent more optimistic than real-world consumption figures. Today, that will change. As of September 1, two new and more stringent testing regimes are to be used for certifying new vehicles going...

It's widely acknowledged that most, if not all, of the autonomous vehicles expected to reach our roads in volume will be electric cars. Without the complexity of a combustion engine and transmission that must be electromechanically controlled, the task of automating the driving of a vehicle is...

When a major lobbying group issues a statement replying to an academic study the same day that study first hits the media, you know it's major. On Monday, the Diesel Technology Forum responded to an article in Nature with a statement that supported "improved real-world testing" of diesel emissions...

The 436 scientists who spend their days testing new vehicles and enforcing environmental rules at the National Fuel Emissions Lab in Ann Arbor, Michigan, face a very uncertain future. The lab sits in the crosshairs of President Trump's proposed budget, which eliminates 99 percent of its funding, as...

It has become increasingly more evident that carmakers must take aggressive steps to ensure that diesel cars and light trucks meet current environmental regulations. Tests done by Emissions Analytics found that the majority of new diesel-powered cars sold in Europe do not meet the Euro 6 emission...

The prospect of ongoing operations as usual continues to darken for the Environmental Protection Agency. According to a detailed internal budget document published in the The Washington Post, the Trump administration wants to eliminate virtually all federal funding for the agency’s vehicle...

Your mileage may vary, as the saying goes. But it turns out that real-world fuel efficiency in European cars varies considerably more from official ratings than in the U.S. And some car brands are so far off from their ratings that a buyer may only get two-thirds of the published fuel efficiency...

Be honest: unless you’re a storm chaser, the chances are you don’t shop for a new car based on its capabilities in heavy storms. But as part of its latest advertising efforts to promote the 2012 Chevrolet Cruze, General Motors wants you to know that the compact sedan can take everything...

Think of plug-in hybrids and you’ll probably think of cars like the 2012 Chevrolet Volt or 2012 Toyota Prius Plug-in Hybrid. But plug-in hybrid army tanks? They might just be closer than you think. Enter the U.S. Army, and its latest prototype test vehicle, a fully-amored plug-in vehicle...
