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.

Daimler exec hypothetically discusses 3-cylinder engines for small hybrids

Is three the magic number of cylinders for Mercedes-Benz parent Daimler and its efforts to build smaller powertrains for its compact hybrids? Potentially, yes, the German automaker could see the need for three-cylinder mills, Automotive News reports. The company doesn't have any plans for them as of yet, though. Daimler executive Bernhard Heil talked with Automotive News about the challenges of using four-cylinder engines in a front-wheel-drive setup and said that three-cylinder engines could work in transverse-mounted powertrains for hybrid cars. For now, though, the company doesn't actually have any plans to go in that direction, Mercedes-Benz spokesman Christoph Horn said in an e-mail to AutoblogGreen. Horn wrote that Heil "actually said that if ever MB would use a three-cylinder engine than [it would be] in a configuration where space is restricted, such as when using a hybrid power train in a compact car." Of course, the only compact "hybrid" that Mercedes-Benz has is the 2015 C-Class, but that refers to the "hybrid" body is made of 48-percent aluminum, up from the current nine percent, as well as steel. It has nothing to do with the powertrain. Beyond that, there's always the Mercedes-Benz S500 Plug-in Hybrid that the company unveiled at the Frankfurt Motor Show last fall, but that model, which will debut in Europe later this year and arrive stateside next year, has a 3.0-liter turbocharged V6 and an 80-kilowatt electric motor that propels the plug-in from 0 to 62 miles per hour in 5.5 seconds. Not exactly three-cylinder territory, that.

Race recap: 2016 Hungarian Grand Prix was the pits

The Hungarian Grand Prix hasn't seen a race this calculated since 2012, when Lewis Hamilton – driving for McLaren – led from pole position to the checkered flag. We don't expect massive action from the Hungaroring, but Hamilton's first win for Mercedes in 2013, the thrilling wet mess in 2014, and Ferrari's surprising dominance in 2015 made us hope for more on-track commotion this year. Hungary denied us that. Hamilton parked his Mercedes-AMG Petronas in second on the grid but stole the lead through Turn 1 and never looked back. Teammate Nico Rosberg yo-yoed behind him in second place, getting into DRS range on a few occasions but never close enough to pass. Red Bull's Daniel Ricciardo kept the leading duo honest, but the Aussie couldn't put genuine fear into the German team and finished third. This is the third year in a row for Ricciardo on the Hungary podium. The pits provided our few scraps of excitement. During a stretch when Ricciardo managed to close on Rosberg, Mercedes told Hamilton to speed up. When Hamilton said he couldn't go faster, Mercedes said they'd pit second-place Rosberg first instead. Suddenly, Hamilton found the extra pace. Ricciardo pitted in early, hoping that fresh tires and fast laps could allow him to pass one or both Mercedes drivers when they pitted, but once Hamilton hit the throttle the Red Bull couldn't respond. Further down the lineup, Jenson Button came in on Lap 5 so McLaren could fix his brake pedal problem. The radio exchange before the stop included one forbidden instruction to Button, though, so the Englishman had to return to the pits for a drive-through penalty. Renault's Jolyon Palmer beat Force India's Nico Hulkenberg in a straight-up pit stop battle on Lap 40, but threw the good work away on Lap 49 with a spin on track that cost him three places. A pit wall miscommunication meant the Force India pit crew wasn't ready for Sergio Perez when the Mexican arrived for his second stop on Lap 43. And Daniel Kvyat's regrettable run at Toro Rosso continued, first with car issues, then a drive-through penalty for speeding in the pit lane. Sebastian Vettel brought his Ferrari home fourth, sniffing Ricciardo's gearbox at the flag but unable to get around the Red Bull. Max Verstappen enacted a replay of the final stages of the Spanish Grand Prix, finishing fifth by holding Ferrari's Kimi Raikkonen behind for 19 laps.
