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.

Hamilton wins in Singapore as Vettel crashes out from pole

SINGAPORE (Reuters) - Lewis Hamilton took a huge stride toward his fourth Formula One title on Sunday by winning an incident-packed Singapore Grand Prix after Ferrari title rival Sebastian Vettel crashed out at the start. The Mercedes driver now has a 28-point cushion over the German with six of the 20 races remaining. Red Bull's Daniel Ricciardo, who also emerged from the opening lap carnage unscathed, was second for the third year in a row with Finland's Valtteri Bottas completing the podium for Mercedes. "God blessed me today for sure," said Hamilton, who set a lap record on his way to a third win in a row, as he spoke from the podium on a night where everything fell into his lap. "I came here today really thinking it was about damage limitation, and we've come out ahead. So I'm very grateful," he said later. "To come to a track that was potentially our weakest circuit, and come away with a win like this and those points, it's really such a fortunate scenario... so I definitely have a skip in my step." The Briton cashed in after Vettel, Ferrari team mate Kimi Raikkonen and Red Bull's front row contender Max Verstappen smashed into each other as they raced off the wet starting grid and into the first corner. Raikkonen had made a storming start from fourth, Vettel a less impressive one from pole position while Verstappen went for the middle ground and was caught in a Ferrari sandwich as they converged. The stewards summoned all three and decided no driver was predominantly to blame. BITTER BLOW The first race to be hit by rain in the decade that Singapore has hosted Formula One had started in treacherous conditions, puddles gleaming in the floodlights, after a formation lap behind the safety car. With Hamilton starting fifth, everything looked set for Vettel to retake the overall lead that he had surrendered only two weeks earlier at Monza in Italy. And then it all went wrong, the collision with Raikkonen punching a hole in the side of Vettel's car before he spun into the wall at turn three. "It's bitter but it's done," said the German, a four times Singapore GP winner, whose retirement ended a run of 18 successive points finishes and left him with a mountain to climb. "Championship-wise it's a big step forward," recognized Mercedes team boss Toto Wolff. "The quickest car and the quickest driver were out within a minute into the race and that can happen all the time.

Infiniti Q50 Red Sport 400 priced at $48,855, AWD at $50,855

Infiniti's most powerful production model, the new Q50 Red Sport 400, now has a starting price. You'll need at least $48,855 for the rear-drive model or $50,855 for all-wheel drive. (Both figures include the $905 destination charge.) A fully loaded, rear-drive Q50 RS400 with Direct Adaptive Steering, navigation, adaptive cruise control, a heated steering wheel, and Infiniti's entire alphabet soup of safety equipment, tops out at $57,045. (Again, add $2,000 for AWD). When it comes to rear-drive competition, the closest base price to the Q50 is the 320-hp BMW 340i. This German undercuts the Infiniti by two grand, $46,795 to $48,855. But the BMW outprices the Q50 as soon as you start selecting options. A 340i with similar equipment to a loaded Q50 Red Sport 400 costs just under $60,000. All-wheel-drive German competitors also lose out in the price war. Like with the rear-drive models, the BMW 340i xDrive undercuts the Q50 RS400 by around $2,000. Add the options, and the Infiniti becomes a better value. The other two big German rivals, the Audi S4 and Mercedes-Benz C450 AMG start at a higher price and only get more expensive. Technically the S4 starts cheaper than the Q50, but only with the standard manual transmission. Selecting the S-Tronic dual-clutch model kicks the price from $50,125 to $51,125, and going for the top-end Prestige trim will bump potential Audi owners up to $57,025. Throw on must-have S4 options, including adaptive cruise control, adaptive dampers, and a sport differential and you'll be shell out $64,425 for the Audi. The Mercedes-Benz C450 AMG is the priciest choice in this group, starting at $51,725, or roughly $900 more than a base Q50 RS400 with AWD. Options, again, are the downfall here. Building a C450 to match a loaded Infiniti will drive the Mercedes' price up to $64,315. While it occupies something of a weird space relative to these vehicles, it's also worth mentioning the Cadillac CTS VSport. It's the only car in this impromptu pricing comparo that can outgun the Q50, with its 3.6-liter, twin-turbo V6 good for 420 hp and 430 lb-ft of torque. It also starts at $60,950, although that includes plenty of standard equipment. All this means that the Q50 Red Sport 400 represents a relative value. It packs more power than the Germans – 80 more than the 340i, 67 more than the S4, and 38 more than the C450 – and a more comprehensive list of options, too.
