Honda, Mazda, Mitsubishi, Mercedes also under diesel emissions scrutiny

The controversy over Volkswagen's diesel emissions scandal isn't limited to the US. In Europe, where diesel engines are far more popular, the issue is shining a harsh light on the NEDC emissions test. As already known, the evaluation does a poor job of reflecting real-world production of NOx, and it appears a significant number of automakers are affected. The Guardian in the UK has been reporting on real-world test results from a company called Emissions Analytics. After the latest round of checks, vehicles from Mercedes-Benz, Honda, Mazda and Mitsubishi were found to generate far more NOx than they should. The newspaper also published similar results for Renault, Nissan, Hyundai, Fiat, Volvo, Jeep, Citroen, VW, and Audi. On average, the figures are about four times over the limit of producing the pollutant. Unlike VW and its defeat device, these automakers aren't actually breaking the rules. The vehicles perform up to the NEDC lab test for emissions, but those results simply aren't translated to the street. "The VW issue in the US was purely the trigger which threw light on a slightly different problem in the EU - widespread legal over-emissions," Nick Molden from Emissions Analytics said to The Guardian. A big fight to decide the future of this issue appears to be on the horizon. Automakers claim that they can't meet the next round of tightening emissions regulations and are asking for compromises. Although, spokespeople for Mercedes and Honda told The Guardian that the brands would be in favor of the stricter rules. Meanwhile, some European governments began backtracking their support of diesels well before this scandal came to light. The added scrutiny certain hasn't helped the future of the oil-burner.

2016 Canadian Grand Prix: A tale of 3 starts and 2 stops

The first curve in the Canadian Formula 1 Grand Prix happened before Turn 1. Lewis Hamilton sat on pole in the Mercedes-AMG Petronas, Sebastian Vettel in a Ferrari behind. That order changed as soon as the lights went out. Hamilton and teammate Nico Rosberg started well enough, but Vettel flew off the line, passing Hamilton in just a few meters. Vettel led through Turn 1 while Hamilton defended against Rosberg trying to pass on the outside by using the entire track. Hamilton bumped his teammate, sending Rosberg into the concrete runoff with an " infuriating but fair" maneuver Hamilton blamed on understeer. The Brit stayed second, his teammate fell to ninth by the time he rejoined the circuit and got back on the gas. The Ferrari finally looked an even match for the Mercedes, Vettel slowly building a gap out front. On Lap 11 the Honda in Jenson Button's McLaren self-ignited just after the hairpin, forcing Button to pull over on the Casino Straight. A Virtual Safety Car slowed the field, convincing Ferrari to pit its drivers. Vettel came in, handing the lead to Hamilton. The marshals cleared Button's car more quickly than expected, so the scuderia didn't get the full time advantage it expected, sending Vettel back on track seven seconds behind the Mercedes. Button's and Ferrari's unplanned stops decided the race. Ferrari had always planned to run a two-stopper, but the early pit didn't give the team a chance to gauge the ultra-soft Pirelli. The ultra-softs lasted longer than anyone expected. Hamilton only pitted once, Vettel had to pit again, and the Ferrari simply couldn't close the gap to the Mercedes even with newer tires. Post-race commentary accused Ferrari of two blunders: giving up track position, and not taking advantage of Mercedes' only known weakness of not being nearly as good in dirty air. If the ultra-softs had fallen off a performance cliff, however, Ferrari's play would have been considered daring and brilliant. Hamilton took his second win of the season, followed by a hard-driving Vettel five seconds later. Valtteri Bottas and Williams got everything right, the Finn taking advantage of a one-stop strategy, a perfectly-timed pit stop, and more unusual Red Bull issues to finish third. It's Williams' first podium of the year. Max Verstappen claimed fourth after two pit stops, holding off a frustrated Rosberg who had to make an unscheduled stop to remedy a slow puncture.

2014 Mercedes B-Class ED battery much bigger than previously stated

There was something unexpected hiding in the new configurator for the 2014 Mercedes-Benz B-Class Electric Drive: a $600 "Temporary range extender." Since we've never heard of such a thing, we had to click through for more. The official explanation runs like this: A suite of options to further increase your driving range includes added insulation of the doors and roof for to increase climate-control efficiency, along with an electrically heated windshield and a range-extending charge function. By pressing a button on the console prior to charging, the maximum charge level for battery will increased for the next charge cycle. The higher-capacity charge can provide up to 17 additional miles of range. The passive features that increase range should be standard in all models, we think. But we were more curious about the battery charge situation. How do you increase a maximum? And is it a good idea to do so? The configurator includes this disclaimer, after all: Range extender should only be used on a limited basis, and could shorten battery life if used excessively. How much is excessive? We investigate below. The B-Class ED has, according to the specs, a 28-kWh battery. First, let's understand what this "temporary range extender" is all about. The B-Class ED has, according to the specs, a 28-kWh battery. But Terry Wei, from the Mercedes-Benz USA product and technology communications department, confirmed to AutoblogGreen that the B-Class ED is actually hiding a 36-kWh battery, but the automaker is calling it a 28-kWh battery because that's how much energy capacity is used in day-to-day use. Most automakers publicly claim the actual capacity and then admit they use a percentage of it. The Chevy Volt, for example, has a 16.5-kWh battery pack, but a "full charge" only fills up around 65 percent of that. In the B-Class ED, the 28 kWh of useable energy provides an EPA-certified 87 miles of range. But, since there are eight kWh of reserve, the temporary range extender (we think of it as a software update accessed by a button) can access some of that and offer the aforementioned 17 miles. Now that we know what we're dealing with, this reminds us of an evolved version of the "remote wireless charging" feature that was touted in the Reva EV. Wei said that the reason the feature is optional is because Mercedes doesn't think most people will need it. Eighty-seven miles is plenty for your average EV driver, but when you want to have 100+ in the tank, you can.
