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.

Race recap: 2016 Monaco Grand Prix gets very wet, a little wild

More than at any other race, the Monaco Grand Prix question is: which combination of demolition derby, Safety Cars, and bad pit strategy will decide the podium? Last year Lewis Hamilton's late, confounding pit stop cost him victory. The year before, Nico Rosberg's qualifying "mistake" put him on pole and Mercedes-AMG Petronas' pit strategy sealed his win – good for Nico, bad for Hamilton and the rest of the field. In 2013 Hamilton dropped from second to fourth when he lollygagged in the pits. In all three years, Rosberg won. The new X factor for 2016: a Red Bull resurgence that helped Daniel Ricciardo clinch his first career pole. Nevertheless, bad pit strategy had its say in the results. Ricciardo built up a 13-second lead by Lap 15 in spite of heavy rains that forced the Safety Car to lead the first eight laps of the race. Ricciardo stopped on Lap 23 to switch to intermediate tires for the drying track, ceding the lead to Hamilton. Hamilton pitted from the lead on Lap 31 for softs, then Red Bull pulled Ricciardo in again on Lap 32 and made a snap decision to put him on ultra softs, but the tires weren't ready when Ricciardo reached his pit box. What should have been a three-second pit stop turned into a 13.6-second pit stop. Ricciardo left the pits as Hamilton came down the straight and the Aussie lost the lead into the first corner. Despite two attempts to pass later in the race, Hamilton finished first, the Aussie second. It's the second race in a row where pit strategy cost Ricciardo a near-certain win. Conversely, Force India nailed both tire strategy and pit timing with Sergio Perez. The Mexican started in eighth but got into third before half the race was done, passing four cars in the pits, and finished on the podium's final step. Otherwise the order barely changed from about half distance, with Ferrari driver Sebatian Vettel in fourth, followed by Fernando Alonso in the McLaren, Nico Hulkenberg in the second Force India, Rosberg in the second Mercedes, Carlos Sainz for Toro Rosso, Jenson Button in the second McLaren, and Felipe Massa taking the final point for tenth for Williams. Storms didn't only hover over the area, though – dark clouds hung around several teams and drivers. Mercedes' reliability is no longer so reliable. The Silver Arrows suffered engine issues on both cars in qualifying, and Hamilton's problem almost kept him from setting a time in Q3.

Hollywood stars drink hydrogen B-Class F-Cell emission water in Death Valley [UPDATE]

A plug-in electric vehicle can be used to power a house during a winter storm, but if you're more worried about the heat of, say, Death Valley, then maybe you'll want a Mercedes-Benz B-Class F-Cell along. That's the message of a new video from Daimler and starring Diane Kruger (Inglourious Basterds) and Joshua Jackson (Fringe) that promotes the company's hydrogen-powered car. The gist? You can drink the tailpipe emissions. The two Hollywood stars drove in Death Vally without any water in their F-Cell but had a special tank hooked up to the tailpipe to collect the H2O drips as they drove in 100+ degree temperatures. There's a reason these two actors were chosen, since they've been driving an F-Cell in their daily lives for two years, according to the Diamler press release. The text is, shall we say, a bit hyperbolic - "Their lives rely on the emissions of the B-Class F-CELL" it says, totally ignoring the film crew that is obviously along for the ride and more than likely had a few bottles with them. Also, when the California Fuel Cell Partnership promoted the same idea a few years ago, it clarified that, "A fuel cell doesn't produce enough water to fill your glass. ... If fact, fuel cells produce about the same amount of water as gasoline vehicle – about 1/3 cup for a full day of driving." Thus, this whole thing is a Hollywood stunt, but it's a visually effective one. See for yourself in the mini-movie below. UPDATE: Daimler has told AutoblogGreen that there was no "extra Hollywood magic" needed for the water collected in the video. Instead, Madeleine Herdlitschka, who works at global communications for Mercedes-Benz Cars, said, "Considering the technical characteristics, the Mercedes-Benz B-Class F-CELL emits about 9 kg of water vapor per kg of hydrogen while driving. The vehicle has a hydrogen capacity of about 3.7 kg, what is sufficient for a max. of about 400 km of range. A tailor-made construction, designed by the production company Markenfilm Crossing in cooperation with our fuel cell experts, made it possible to collect the water in a tank - previously cooling the vapor with a specially designed pipe system."
