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 Mexican Grand Prix is a lot like old times

The last time Formula One visited Mexico, in 1992, 26 cars powered by eight engine manufacturers (counting Honda and Mugen-Honda separately) lined up on the grid; it would have been nine engine makers but the Brabham-Judd cars failed to qualify. In 1992 Lewis Hamilton was seven years old, Sebastian Vettel was five, Max Verstappen was still five years away from being born. Two of the current Sky Sports F1 commentary team, Martin Brundle and Johnny Herbert, were drivers. The starting three were Nigel Mansell on pole – 39 years old, this the year he'd win his only World Championship – and Riccardo Patrese both driving Williams-Renault cars, followed by Michael Schumacher in a Benetton-Ford. Only 13 of the 26 starters would finish. The circuit is has been reworked to today's safer standards, the track surface is brand new and slippery, but the atmosphere and packed grandstands haven't changed. Nico Rosberg was another point of consistency, scoring pole position for the fourth race in a row to beat his now-World-Champion teammate Hamilton by almost two-tenths of a second. The last time Rosberg turned pole position into a victory? The Spanish Grand Prix back in May. Vettel locked up third for Ferrari, followed by the Infiniti Red Bull Racing duo of Daniil Kvyat and Daniel Ricciardo. Williams went two-up as well, Valtteri Bottas in sixth ahead of Felipe Massa in seventh. Max Verstappen turned in a great late lap to reserve eighth place, Sergio Perez did all he could in front of his home crowd to get ninth, teammate Nico Hulkenberg the caboose in the top ten. In that 1992 race the first three on the grid finished the race in the same order after Mansell dominated, and it was almost the same in 2015. If Rosberg had driven the whole season like he drove today the Driver's World Championship would still be up for grabs. He got a great start and held his line through the first corner, coming out ahead of Hamilton through the initial kinks, pulling away as soon as he got to the straight. Hamilton was never more than a few seconds behind, but every time the Brit inched closer the German found a few more tenths to keep his distance. The field got bunched up when the Safety Car came out on Lap 53 after Vettel spun and got stuck in the barriers, but Rosberg handled the restart perfectly. Both drivers made small mistakes in the last few laps while driving on the edge, but Rosberg earned a strong victory, crossing the line two seconds ahead of his teammate.

2016 Japanese Grand Prix | Hamilton faces the beginning of the end

We're told the Japanese mamushi viper haunts the undergrowth around Suzuka. If the pit viper attended the weekend's Japanese Grand Prix, it avoided human visitors but it put a nasty bite on Lewis Hamilton's championship hopes. The Briton, lined up second on the grid next to Mercedes-AMG Petronas teammate Nico Rosberg, flubbed his start. By the end of Turn 1 Hamilton was in eighth. Hamilton didn't suffer alone. The beginning of the race was a melee; many of the leaders got caught out either by the damp track or by having to swerve around slow starters. Only Mercedes' Nico Rosberg and Red Bull's Max Verstappen took off clean. The German rolled up another lights-to-flag victory despite the pass-happy race happening behind him. Rosberg was as unbothered by the Dutchman in second place as he was by the official Formula 1 camera feed. Verstappen didn't have much work to do until the final ten laps of the race. Thanks to the Mercedes team's strategy – or Ferrari waiting too long to pit – Hamilton got up to third on Lap 36 of 53. Unable to make a DRS-enabled pass on Verstappen down the front straight toward the end of the race, the Mercedes driver took a creative line through Spoon corner. Closing in down the back straight, Hamilton jinked inside to try a pass through the final chicane. Verstappen moved over in the braking zone while Hamilton was still behind him, closing the door on the move. Hamilton protested over his team radio, but seemed resigned to a third place finish after the incident – he didn't try any more passes in the final laps. The Ferrari duo of Sebastian Vettel and Kimi Raikkonen crossed the line fourth and fifth, respectively, in recovery drives after penalties. The scuderia tried an aggressive final stint after Hamilton successfully undercut Vettel in the pits. Ferrari put Vettel on the soft-compound Pirellis so he could hunt the Mercedes, but after a few laps of close pursuit the tires gave up and Vettel fell back. Daniel Ricciardo couldn't get comfortable in his Red Bull the entire weekend. The Aussie finished where he started, in sixth place. Sergio Perez and Nico Hulkenberg followed the Red Bull home in two-up formation for Force India, Williams doing the same in the final two points-paying positions with Felipe Massa and Valtteri Bottas. Rosberg's 23rd career victory – his ninth of the season and first ever in Japan – puts him 33 points ahead of Hamilton in the Driver's Championship with four races left.
