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.

Nissan-Renault and game developer plan driverless ride-hailing

TOKYO - The Nissan and Renault alliance plans to launch driverless ride-hailing and ride-sharing services in coming years, as the automakers look beyond making and selling cars to survive an industry being quickly transformed by new services. Automakers are leveraging expertise in automated driving functions for mass-market cars to develop mobility services, as they compete with tech firms such as Alphabet Inc and Uber in the fast-growing "pay-per-ride" market which threatens to hit demand for car ownership. Ogi Redzic, head of Nissan-Renault's Connected Vehicles and Mobility Services division, said the alliance would begin self-driving services based on its electric cars "certainly within 10 years," though not likely before 2020. "We think that the big opportunity for us is in automation, electric vehicles and ride-sharing and hailing together," Redzic said in an interview on Thursday. Nissan and Renault join a small group of automakers aiming to enter the ride-hailing market, which Goldman Sachs last month estimated would grow eightfold by 2030 to be five times the size of the taxi market. Redzic said the Japanese and French partners were testing self-driving vehicles, and that any service would run on pre-mapped courses with predetermined pick-up and drop-off points. The two automakers are developing the system with Japanese game software maker DeNA Co Ltd and French public transport operator Transdev SA. German rival BMW AG is also testing autonomous vehicles for use in ride-hailing services, while Uber has been developing self-driving technology. U.S. tech firm nuTonomy Inc and ride services company Lyft Inc, which counts General Motors Co as a major shareholder, this month announced they would begin piloting an autonomous vehicle ride-hailing service in Boston. Redzic said to market a self-driving service, regulations need to change to allow driverless cars on roads. At the moment, most global jurisdictions do not expressly authorise vehicles to operate on regular roads without a driver. "It doesn't just depend on us," he said. "To become fully driverless you need laws to change." Reporting by Naomi TajitsuRelated Video:

GT-R driver walks away from terrifying dragstrip accident

With all-wheel drive, launch control and a dual-clutch transmission, the Nissan GT-R may be easier to manage than most supercars. But that doesn't mean that dragging one on a wet strip is a good idea.
Filmed at the Unlimited 500+ drag race in Moscow, Russia, this video depicts a pair of GT-Rs going head to head. But things didn't go quite as planned when the driver of one lost control of her twin-turbo supercar. We'll let the video below speak for itself, but thankfully it appears no one was hurt - an outcome that seems particularly remarkable in light of the fact that it appears that the driver was not wearing a fire suit or helmet.
