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.

Strains between France and Italy risk Renault-FCA merger

PARIS/ROME — Fiat Chrysler's proposed $35 billion merger with Renault has cheered investors, won conditional support from Paris and Rome and even earned cautious backing from trade unions. Beneath this veneer, however, the bold attempt to create the world's third-largest carmaker risks becoming rapidly embroiled in the fraught relationship between France's europhile President Emmanuel Macron and Italy's euroskeptic leaders. For while Deputy Prime Minister Matteo Salvini hailed the proposal as a "brilliant operation," Italy's creaking, state-subsidized Fiat factories are likely to bear the brunt of any production-related cost savings. FCA and Renault said this week that more than 5 billion euros ($5.6 billion) of annual savings would come mainly from combining platforms, consolidating powertrain and electrification investments and the benefits of increased scale. Salvini and France's Finance Minister Bruno Le Maire, who called the deal a "good opportunity" to build a European industrial champion able to compete with China and the United States, have both said they want guarantees on local jobs. "It's not every day that I agree with Salvini," said Le Maire, whose government appears to hold the trump cards. When it comes to where any job cuts fall, France will be helped by its existing 15 percent holding in Renault, whose superior efficiency at its five French plants makes it better placed to handle a supply glut, the demise of the petrol engine and the investments needed for electric and autonomous vehicles. "It will take many, many years to find real savings, and ugly political and operational realities can often swamp the potential of such new entities," Bernstein analyst Max Warburton said of the FCA-Renault plan to rival Japan's Toyota and Germany's Volkswagen. Advantage France? As well as Italy's government having to cope with the aftermath of European elections, which coincided with news of the FCA-Renault plans, political leaders in Rome were only informed shortly before the deal was made public, an FCA source said. This contrasted with the way the French government was treated, with Fiat Chrysler Chairman John Elkann, a fluent French speaker, letting it know of his merger proposal to Renault weeks ago, a French government official said.

Nismo GT-R poised to be fastest Nissan ever

For almost every year since the Nissan GT-R first debuted, Nissan has been figuring out how to cram more power under the hood or give it 911-like quickness around the Nürburgring. Looking to create a brand image for its performance arm, we already knew that a hotter, Nismo-branded GT-R was in the works, but it seems some details may have leaked regarding this new Nismo GT-R.
While little has been spoken of this Super GT-R since February, Top Gear is reporting that Nismo is planning to make improvements to the coupe's power, handing and styling - three things that we're sure few have complained about since 2009. What could this mean for the GT-R? According to the article, Nismo could be looking to raise horsepower from the current 545-hp mark to more than 570 hp, and handling upgrades could give the car a 'Ring lap time of seven minutes and 22 seconds, which as Top Gear points out, is four seconds quicker than the new 911 GT3.
