Why it's difficult to accurately test the efficiency of a plug-in car

When it comes to electric vehicles and plug-ins in general, the Environmental Protection Agency-certified range is a hugely important number. While actual range anxiety is largely psychological, the magic number does provide a point of comparison of buyers considering one EV over another. The driving distance is also often touted by automakers when marketing their models. Unfortunately, as Green Car Reports finds in a recent deep dive, the way the EPA calculates the figure is a convoluted mess, and discovering the reasons why is definitely worth the read. The issue isn't about bad science but instead comes down to vague wording. The EPA's accepted range test is sourced from an evaluation called J-1634 from the Society of Automotive Engineers, and it seems to provide balanced results for vehicles that automatically reach a single state of charge when plugged in. However for models with multiple charge settings, the situation gets complicated very quickly. Of course, these modes are often created in the software, meaning that a car's certified driving distance can change with just a few taps of the keyboard without the real world results owners might experience actually changing. By showing the test's effects on the certified range for the Tesla Model S, Nissan Leaf and Mercedes-Benz B-Class Electric Drive over the last few years, Green Car Reports makes a compelling argument that it's the evaluation that needs to change. Thankfully, it appears that the solution is a very simple one. Get the details here.

VW, Fiat, Mercedes could be CNG winners in Europe

Fiat ads in the US try to play up the exotic, sexy side of Italian culture. On the home front in Italy, however, passenger-vehicle sales are marked by something less edgy and quite a bit more practical: the growth of compressed-natural-gas (CNG) powered car sales. In fact, Italy is leading a group of European countries where CNG sales are on the upswing and may be benefiting automakers like VW, Fiat and Mercedes-Benz, according to Automotive News. VW started sales of its Golf TGI natural-gas vehicle this year – the company's fourth in Europe – while Mercedes-Benz added a natural-gas B-class model. Fiat accounts for about 50 percent of CNG vehicles sold on the continent. In all, Europe's CNG sales through September totaled about 67,000, up seven percent from a year earlier, Automotive News Europe says, citing research firm JATO Dynamics. And the number of CNG vehicles on Europe's roads could jump tenfold within the next decade. The draw is a combination of lower refueling prices and a CNG drivetrain that typically emits less CO2 than diesel vehicles. As for Italy, about five percent of new-vehicle sales are CNG. To put that into perspective, hybrids, battery-electric vehicles, plug-in hybrids and diesels combined to account for about 4.2 percent of US vehicle sales last year.
