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.

2015 Chinese Grand Prix shines bright sun on the dark days of racing

Yes, we tuned into the Formula One Grand Prix in Shanghai China to see a race. But we all know we really tuned in to see if Ferrari, or any other team, could make it a competitive race with Mercedes-AMG Petronas. Based on qualifying, things didn't get off the best of starts: Lewis Hamilton made it four-out-of-four at the front, leading all three Free Practice sessions and then taking pole position in his Mercedes. Nico Rosberg is making the most of his time in the simulator, getting closer to Hamilton as the months go by. This time he lined up in second, just 0.042 in arrears. Ferrari did its best to temper expectations after Malaysia. Even though Sebastian Vettel qualified in third, almost a second behind Hamilton, the Scuderia's race pace is still considered a danger. Kimi Raikkonen's final hot lap went sour in Turn 3 and dropped the Finn to sixth place on the grid. In between the Ferraris, Williams is another team desperately working to maintain its advantage, and both of its drivers capitalized on Raikkonen's misfortune. Felipe Massa took fourth, Valtteri Bottas was in fifth. Daniel Ricciardo led the Infiniti Red Bull Racing charge in seventh, ahead of Romain Grosjean in the Lotus earning a spirits-lifting eighth. The two Saubers continue to show how good the Ferrari engine is, with Felipe Nasr taking ninth position and teammate Marcus Ericsson in tenth. Yet when the lights went out, so did the racing, for the most part. At the end of the first lap, because of some excellent moves by Raikkonen on both Williams' and a terrible start by Ricciardo that dropped him to seventeenth, the order was Hamilton, Rosberg, Vettel, Raikkonen, Massa, Bottas, Grosjean, Nasr, Ericsson, and Pastor Maldonado in the Lotus rounding out the top ten. At the end of the race, the only positions that had changed were the final two: Ricciardo had a laps-long battle with Ericsson, passing, getting repassed, then passing again to take ninth for good, with Ericsson finishing tenth. Maldonado suffered the worst in a battle with Jenson Button in the McLaren, when Button misjudged the entry into Turn 1 for a pass and clouted the back of the Lotus. Button was able to finish but Maldonado had to retire. Yes, there were some decent moments in between, like Bottas getting by Massa at the start, then Raikkonen getting past Massa in the first few corners and the Finn's move on Bottas also letting Massa through.

Mercedes spent ˆ250 million to win Formula One titles last year

Success in Formula One requires skill, diligence, commitment and ingenuity. It also takes truckloads of money. In the case of Mercedes in last year's world championship, in which it took both the drivers' and constructors' titles in dominant style, those truckloads came to ˆ250 million last season alone – equivalent to over $285m in dead presidents. A report from Germany's own Auto Motor und Sport details the staggering investment that Mercedes made in order to get to the winner's circle last season. After 15 seasons with McLaren netting one constructors' and three drivers' titles, Mercedes motorsport chief Norbert Haug convinced the Daimler board late in 2009 to take over the Brawn GP team that had just won the championship. Because the team would be getting a large payout from Bernie Ecclestone as the returning champions the following year, and with sponsors lined up, Daimler only had to pony up a small portion of a smaller budget: in 2010 (its first season under the Mercedes banner), the team ran on a budget of "only" ˆ153 million ($175m). Over the course of the following seasons, though, the team's share of the TV revenues from Formula One Management went down as Mercedes struggled to climb back up the standings, but successive advocates (including Haug, Ross Brawn and Niki Lauda) successfully convinced the bean-counters in Stuttgart to ratchet up the payments. By 2012, the budget was expanded to ˆ200 million, and further climbed to ˆ250 million in 2013 and 2014. Fortunately for Daimler, the investment was starting to pay off by then as the team finished second in the constructors' standings in 2013, bringing ˆ74 million in from Ecclestone's coffers to cover roughly a third of the budget. With Malaysian oil giant Petronas alone kicking in upwards of another ˆ30 million per season as title sponsor (as of 2009 when it signed on), and untold millions more coming in from other partners, it looks like the actual cost to Daimler for securing both world titles and a winning reputation was actually more like hundred million or so.
