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.

NHTSA releases updated Takata airbag recalled cars list, but it still has errors

Unfortunately, the government's list still contains errors.
The National Highway Traffic Safety Administration has issued an updated list of vehicle models that it's urging owners to repair under the mushrooming Takata airbag inflator recall. The latest version adds vehicles from new automakers like Subaru and Ford that are missing from the original announcement, and it also removes erroneous entries from General Motors, leaving only the 2005 Saab 9-2X (a reskinned Subaru WRX), and the 2003-2005 Pontiac Vibe, a joint project with Toyota.

Nissan presents NV200 is the brave new face of London taxis [w/video]

In most cities, just about any vehicle can serve as a taxi - so long as it meets the owner/operator's requirements for reliability, comfort and utility. But certain cities have their own unique taxis, and Nissan has been working hard to corner those markets. It has already designed specific taxis for such locations as New York, Barcelona and Tokyo, but its latest effort will bring a new Hackney Carriage to the streets of London.
A year and a half ago, Nissan displayed its NV200 on the streets of London in traditional black livery. But this new design takes the customization for the British capital one step further. Working closely with the mayor's office and with cab drivers across the city, Nissan's European design center in the Paddington district has reskinned the NV200 specifically to serve as the new black cab in London. The new face features round headlights, a new grille, LED lighting and a restyled front bumper. The steering has also been reconfigured to meet the 25-foot turning circle requirements for Hackney Carriages, as the black cabs are known on the streets of London.
The result is a distinctly British take on the NV200 taxi - one that we're guessing won't go without its fair share of controversy. Nissan will begin offering the black cab at the end of the year with a 1.6-liter gasoline engine mated to an automatic transmission, a powertrain said to be cleaner than the diesels used in existing taxis. And Nissan should know, having supplied many of those 2.7-liter turbodiesels in the '80s and '90s. But if that's not clean enough, the Japanese automaker will also begin selling an electric version, the e-NV200, starting next year.
