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.

Five B-Class F-Cells go from SF-LA using public hydrogen stations

California's hydrogen islands in Los Angeles and San Francisco finally got the bridge they needed to become the "Hydrogen Highway." With the completion of a permanent public station in Coalinga built by FirstElement Fuel, 205 miles north of LA, 183 miles south of SF, fuel-cell-vehicle owners can complete the road trip without worry. Mercedes-Benz did just that with five B-Class F-Cell customers, spending three days covering 1,000 miles and filling up only at public permanent stations in Burbank, Coalinga, West Sacramento, and Emeryville. Mercedes says there are ten stations in California now, but more than 40 are scheduled to open in 2016, and about ten more every year after that through 2023, when there should be 123 open stations. The company's US fuel-cell fleet is 70 strong and has covered more than two million miles in the five years they've been on the roads here. On average that means each car has driven just 5,714 miles per year, but that number should go up now that they can stretch their hydrogen stacks. The press release below has more information. Nearly 1,000 fuel cell electric miles: Crossing California on Hydrogen - Five Mercedes-Benz B-Class F-CELL complete emission-free drive from Los Angeles to Northern California while only filling up at public hydrogen stations - "California Hydrogen Highway" is connecting the dots - U.S. F-CELL customers have accumulated over 2 million miles since 2010 Stuttgart, Oct 27, 2015 - Mercedes-Benz B-Class F-CELL customers ventured beyond Southern California last week for the very first time, while only filling up at existing public hydrogen stations along the route from Los Angeles to San Francisco. The opening of a new hydrogen station in Coalinga along the I-5 corridor made this opportunity possible. A team driving five B-Class F-CELL refilled at four permanent hydrogen fueling stations located in Burbank, Coalinga, West Sacramento and Emeryville, accumulating nearly 1,000 miles over the course of their three day trip. Three F-CELL customers were accompanied by a team from Mercedes-Benz Research and Development North America based in Long Beach. The purpose of this unique road trip was to highlight the growing hydrogen station network and to show that the vision of the California Hydrogen Highway is becoming reality. Early adopter Loki Efaw who has been an F-CELL driver since 2011 believes fuel cells are the future: "I don't want a car that only takes me to work and back before I have to plug it in.

The 10 car brands most expensive to maintain over 10 years

Car maintenance has got to be one of the least fun things you can do with your free time, right behind going to the dentist and filing your taxes. However, depending on the brand you buy, your time spent at the shop could be much more than you bargained for. Consumer Reports’ new study on the most- and least-expensive-to-maintain car brands found that European car companies are most likely to break your wallet with costs nearly five times that of the automakers at the other end of the spectrum. Land Rover had the highest ten-year maintenance costs, at an average of $19,250. Porsche was second worst with $14,090 in costs. 10 car brands most expensive to maintain over 10 years: Land Rover: $19,250 Porsche: $14,090 Mercedes-Benz: $10,525 Audi: $9,890 BMW: $9,500 Volvo: $9,285 Infiniti: $8,500 Acura: $7,800 Mini: $7,625 Subaru: $7,200 The Euro brands at the “top” of this list arenÂ’t all that surprising. Land Rover has consistently landed as one of the most expensive vehicle brands to maintain for years now, though Porsche is generally viewed as being one of the more solid performance brands. That could suggest that some models donÂ’t always require more repairs, but the fixes they do need are significantly more expensive. Tesla, Buick, and Toyota were the three cheapest to maintain car brands, with 10-year maintenance costs of $4,035, $4,900, and $4,900, respectively. Consumer Reports noted that these numbers could be slightly skewed due to the fact that some automakers offer free maintenance for the first few years of ownership, and all companies cover their new vehicles for at least a few years after the purchase. Routine maintenance is a great way to avoid costly repairs over time, as itÂ’s much cheaper to catch a problem before it starts causing other issues. Check your oil, rotate your tires, and avoid driving like a wild person, and youÂ’ll likely fare much better than others, even if you own one of the scarier-to-maintain brands.
