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.

2014 Mercedes-Benz B-Class ED has 87-mile range, 84 MPGe

Well, that extra weight had to be felt somewhere. With Mercedes-Benz getting ready to start US sales of its B-Class Electric drive this summer, the big question was how well its range would stack up against other electric vehicles sold in the States. Turns out, the Benz is a bit of a juice hog. Let's say up front that the 87-mile single-charge range of the Mercedes-Benz actually stacks up nicely against its competition, since that distance puts the new model right in line with the Nissan Leaf and BMW i3 (we'll ignore the Tesla Model S for a second, here). You can find the numbers at the US Department of Energy's FuelEconomy website. As far as miles per gallon equivalent ratings, though, the Benz's steel frame makes it come up short, as it's about 1,300 pounds heavier than the carbon-fiber-body i3 and about 600 pounds heavier than the Leaf. The B-Class EV has a bigger battery than the i3 or the Leaf (36 kWh compared to 22 kWh for the i3 and 24 kWh for the Leaf) and that's one reason the car gets an 84 MPGe rating, which is about 26 percent less than the Leaf's and 32 percent less than the i3's. But at least the local utility companies will be happy. Mercedes-Benz priced the 177-horsepower B-Class ED in April at $41,450, or $100 more than the i3.

Race Recap: 2016 Austrian GP is mishaps from start to finish

At the 2015 US Formula 1 Grand Prix, rain mixed up the grid and a first-lap incident cast the die for the race. The Austin, Texas event made highlight reels for those reasons and because it decided the Driver's Championship. At the 2016 Austrian F1 Grand Prix, rain mixed up the grid and a last-lap incident cast the die for the race. The Spielbergring race will feature in this year's highlight reel because it might force Mercedes-AMG Petronas to make some hard decisions about the rest of the season. For the first time this season, Lewis Hamilton converted pole position into a lead through Turn 1, and began slowly pulling away from the field. Teammate Nico Rosberg started from sixth because of a gearbox penalty, but was up to third when he pitted on Lap 11. Mercedes normally pits the lead driver first, in this case being Hamilton, but Mercedes wanted to get Rosberg ahead of the two Ferraris. Hamilton pitted on Lap 22, emerging behind Rosberg because of a slow stop. Sebastian Vettel led the race for Ferrari on Lap 27 when his right rear tire exploded coming down the start-finish straight – an eerie reminder of the 2015 Belgian Grand Prix. The Safety Car rolled out, yet when racing resumed Rosberg stayed ahead. After the two Mercs came in for second stops everyone expected Hamilton to lead, but Hamilton had messed up his in-lap and lost a cumulative 3.3 seconds during his actual stops compared to Rosberg's pit-stop times. The Brit remained second. Hamilton chased his teammate for the final 15 laps. At the beginning of the last lap Rosberg messed up Turn 1 and Hamilton closed in. Rosberg took the inside line into Turn 2 as Hamilton pulled up on the outside, then Rosberg appeared to drive straight on as if he simply wasn't going to turn. Hamilton turned in, colliding with Rosberg and driving over the German's front wing. By the end of Turn 2, Hamilton had the lead and Rosberg had a broken car. The Brit won, the German puttered home to finish fourth. The incident promoted Max Verstappen to second and Kimi Raikkonen to third. Verstappen scored his second podium for Red Bull after his victory in Spain. Conversely, Raikkonen's third place for Ferrari was more gifted scraps for the scuderia. Daniel Ricciardo came fifth in the second Red Bull, Jenson Button delivered a terrific sixth for McLaren- Honda, Romain Grosjean got Haas back in the points, Carlos Sainz, Jr. secured eighth for Toro Rosso, and Valtteri Bottas in ninth for Williams.
