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.

Lewis Hamilton wins in Hungary to stretch F1 title lead over Sebastian Vettel

BUDAPEST (Reuters) - Formula One world champion Lewis Hamilton won the Hungarian Grand Prix from pole position for Mercedes on Sunday to go into the August break with a 24-point lead over Ferrari rival Sebastian Vettel. Vettel was runner-up in Hungary, 17.1 seconds behind, and survived a late collision with Hamilton's team mate Valtteri Bottas who also banged bodywork with Red Bull's Australian Daniel Ricciardo. The victory was Hamilton's record sixth in Hungary, fifth of the season and 67th of his career. Ferrari, mourning the death of former chairman Sergio Marchionne, had Kimi Raikkonen finish third to complete a podium of champions on a dry and sweltering afternoon at the Hungaroring outside Budapest. In a race effectively decided by Saturday's wet qualifying, when Mercedes locked out the front row of the grid against expectation, Hamilton was never challenged. "We came here knowing Ferrari would be really quick this weekend so to come out with these points, we'll definitely take it as a bonus," said Hamilton in a pitlane interview after embracing team members. "I'm really happy with how strong it's come in the last couple of races. We've got to come strong in the next half," added the 33-year-old, who won in Germany from 14th place on the grid a weekend earlier. After 12 races, Hamilton has 213 points to Vettel's 189. Tire strategies were also crucial at a relatively slow and twisty circuit where overtaking is always difficult, with track temperatures hovering around 50 degrees Celsius. Vettel started on the softs and went for a longer first stint than Mercedes, worried by Ferrari's quick getaways, who opted for ultrasofts that were quicker at the start but faded more rapidly. Lining up in fourth place on the grid, Vettel grabbed third from Raikkonen immediately but could not find a way past Bottas who slotted in behind Hamilton as a defense against the red threat. "We were out of position. I think we could have gone with Lewis today with the race pace," said Vettel. "P2 is not really what we wanted this weekend but I think it was the maximum today." ANGRY VERSTAPPEN Raikkonen, without water during the race after Ferrari forgot to connect the bottle, made two stops and agreed third – his fifth successive podium finish – was the best he could have hoped for in the circumstances. "We caught up with Bottas after the first stop but there was no chance to overtake. So our option was to stop again and try again.

2015 Brazilian Grand Prix is the same as it ever was

At this point, we hope Nico Rosberg is planning to carry his current qualifying form into the 2016 season and back it up with the same kind of race-day cojones he showed winning the race in Mexico City two weeks ago. The Mercedes-AMG Petronas driver got it right enough again on Saturday afternoon to take his fifth consecutive pole position ahead of teammate Lewis Hamilton by almost a tenth of a second. It's the same one-two from Brazil last year. The bad news for the rest of the field is that the winner in Brazil the last seven years has been one of the two drivers on the front row. Last year it was the Williams duo that lined up behind Mercedes, this year it's Ferrari. Sebastian Vettel plays the stalking horse, securing third in his Ferrari ahead of teammate Kimi Raikkonen in fourth. Williams driver Valtteri Bottas actually qualified in fourth, but he had to serve a three-spot grid penalty for passing under red flags in Free Practice 2, so he started sixth. That promoted Sahara Force India driver Nico Hulkenberg up to fifth. Daniil Kvyat was the quickest representative from Infiniti Red Bull Racing, getting into seventh even with a Renault power unit that's weak on some of the key stretches at the Interlagos track. Felipe Massa had the second Williams in eighth, in front of the second Red Bull driven by Daniel Ricciardo in ninth. Toro Rosso hasn't confirmed its drivers for next year but Max Verstappen keeps making it hard to look elsewhere, taking 10th. Rosberg is working nearly the same trick he pulled last year: drive like a second driver for most of the year, drive like a world champion for the last quarter of a season. He pulled away at the start and covered Hamilton just enough on the run to the first corner to keep Hamilton on the outside. By the end of Turn 1 the German had the lead and didn't give it up for the rest of the race outside of pit stops. Without overwhelming pace to pass and unable to follow closely, Hamilton could do nothing except ask his team for a different strategy to go for the win. When Mercedes told him "No," trying to protect Rosberg's second place in the championship ahead of Vettel, that was the race. Just like last year, Rosberg and Hamilton finished one-two. Vettel, Raikkonen, Bottas, Hulkenberg, and Kvyat drove lonely races to finish in positions three through seven.
