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 needs to step up in his 200th F1 race

LONDON — Lewis Hamilton will start the 200th grand prix of his Formula One career in Belgium this weekend, but the triple world champion has smaller but more significant numbers on his mind. Refreshed from an August break in the Caribbean, including a trip to Cuba in his role as UNICEF ambassador, the Mercedes driver is 14 points behind championship leader Sebastian Vettel as he revs up for the second half of the season. A fifth victory of 2017 for the Briton would put the pressure back on Ferrari's Vettel, and Hamilton can celebrate another milestone by bagging pole position on Saturday at the long and fast Spa-Francorchamps circuit. That would see Hamilton, who sportingly relinquished third place to team mate Valtteri Bottas in Hungary before the summer shutdown, match the record of 68 poles set by Michael Schumacher with Ferrari in 2006. Mercedes has won the last two Belgian Grands Prix, with now-retired 2016 world champion Nico Rosberg triumphant from pole last year after Hamilton won in 2015. Nobody will be taking anything for granted, however, after Ferrari's one-two win in Budapest at the end of July. "On paper, people will assume that Spa should suit our car because it is a circuit where aerodynamic efficiency is extremely important," Mercedes team boss Toto Wolff said. "But assumptions are dangerous — we have seen too many times already this season that the form book can be rewritten from one weekend to the next. So we will be making no assumptions." Hamilton has won twice before at Spa, as has Vettel, but the track — a classic blast from the past — has not been particularly kind to him. In 2008, when he won his first title, the Briton was demoted from first to third after the race for cutting a chicane, with then Ferrari rival Felipe Massa savoring victory instead. Spa can often be a lottery, with its capricious weather, and rain could be a boon for Red Bull's Belgian-born Dutch teenager Max Verstappen, who can count on plenty of local support in what amounts to a home race. "I just love the track and it'll be nice seeing so many orange (Dutch) fans in the grandstands," he said. "Spa is my favorite track of the year. You have to get everything right but when you get a good lap it's very rewarding." Belgium could also be good for Ferrari's Kimi Raikkonen, who arrives with a new contract for 2018 in his pocket.
