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.

Lewis Hamilton takes pole position at German GP as Ferrari falters

HOCKENHEIM, Germany — Lewis Hamilton took pole position for the German Grand Prix on Saturday, while Sebastian Vettel's miserable form continued for Ferrari as he was unable to even set a time and will start from the back. It got even worse for Ferrari as Vettel's teammate Charles Leclerc was unable to start the last part of qualifying, known as Q3, and is set to begin from 10th place on the grid on Sunday. "I don't know really how we did it today. I'm not quite sure what happened to the Ferraris," Hamilton said. "I think if Leclerc had done a lap at the end, it would have been close between us." Ferrari is winless in 10 races this season and that terrible run looks to continue, while Hamilton is aiming for a sixth win in seven. It was a record-extending 87th pole for the five-time world champion, who is 11 wins shy of Michael Schumacher's record of 91. Hamilton starts on the front row alongside Red Bull's Max Verstappen, who knocked Hamilton's Mercedes teammate Valtteri Bottas into third place. Red Bull's Pierre Gasly goes from fourth. "A bit disappointed with qualifying and I just struggled," said Bottas, who is level with Hamilton on four poles this season. "Ferrari (were) extremely quick and we knew it would be difficult to beat them ... We've been a bit lucky." Vettel, who crashed at last year's German GP despite leading from pole, looked visibly upset as he climbed out of his car in the team garage. The incident happened during the first part of qualifying, making him one of five drivers eliminated from Q1. The issue appeared to be related to a turbo problem, even more surprising given Ferrari had topped all three practice sessions heading into qualifying. Worried faces in the Ferrari garage turned to sheer horror as mechanics then detected a problem on Leclerc's car, ruling him out of the top-10 shootout in Q3. "Mine was a fuel system problem. It is a shame but we will be trying to understand what happened and not to reproduce it. The car felt great today so it's a shame it ended like this," Leclerc said. "I feel for the whole team. I will give absolutely everything to make everyone smile again tomorrow." Television footage showed a Ferrari fan in the stands sinking his face into his hands in disbelief. Mercedes head of motorsport Toto Wolff was sympathetic when commenting on Ferrari's latest setback. "It is a shame for Ferrari and for Sebastian at his home GP," Wolff told broadcaster Sky Sports, adding.

Lewis Hamilton accepts Vettel's apology, has 'utmost respect'

SPIELBERG, Austria - Triple world champion Lewis Hamilton said he still had "the utmost respect" for Formula One title rival Sebastian Vettel after accepting a public apology from the Ferrari driver on Thursday. Speaking to reporters at a crowded Austrian Grand Prix news conference, the two men addressed a "road rage" controversy that has dominated the headlines since the June 25 race in Azerbaijan. "I still have the utmost respect for him as a driver and will continue to race him hard through the rest of the season," declared Hamilton, who said at the time that Vettel had "disgraced himself" by driving into him in Baku. He said Vettel called him on the Monday after the race and then texted an apology, which he accepted. The championship leader had driven into the back of Hamilton's Mercedes while both were following the safety car in first and second places, waiting for it to return to the pits. Vettel then pulled alongside, gesticulating angrily, before banging wheels. The German, a four times world champion, later accused Hamilton of "brake-testing" him by slowing suddenly. The car's telemetry subsequently showed that was not the case and Hamilton said the accusation was one he particularly wanted correcting. Vettel was handed a 10-second stop-and-go penalty, and finished fourth. He was then summoned to a hearing in Paris last Monday where the governing body declared the matter closed. Initially reluctant to dwell on the matter, saying he did not want to "pump this up more than it is already", the Ferrari driver on Thursday repeated the written apology. "It was the wrong move to drive alongside him and hit his tyres," he said. "I don't think there was any bad intention (by Hamilton). I don't think he actually brake-tested me. I was upset and over-reacted. I am not proud of the moment." Hamilton, 14 points behind Vettel after eight races, missed out on victory in Baku after a headrest worked loose and he had to pit. He finished fifth. Before Baku, the two world champions had made much of their mutual respect and the budding "bromance" seemed to be back on. "It's nice to hear that we are able to move forward," Vettel said. "I think the respect we have for each other on and off track helps us in this regard." Reporting by Alan Baldwin Related Video:
