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.

Chris Harris falls in love with Mercedes-AMG GT at Laguna Seca

It's not every day that an automaker goes down a market segment and still comes off as even more ambitious, but that's exactly what Mercedes has done with the new AMG GT. While the SLS was bigger and more expensive, with the new GT, Mercedes has set its sights on one of the most iconic sports cars of all time. That, of course, would be the Porsche 911, and the big question is whether Benz has achieved its target. For the answer, we turn to none other than the Monkey himself – the inimitable Chris Harris, who recently went solo with his own YouTube channel. And for his latest segment, he took the latest German sports car around no less suitable a track than Mazda Raceway Laguna Seca.

Valtteri Bottas on pole for Formula One's 1,000th race

Valtteri Bottas will start Formula One's 1,000th world championship race from pole position after leading Mercedes team mate Lewis Hamilton in a front row lockout at the Chinese Grand Prix on Saturday. Ferrari's Sebastian Vettel qualified third, ahead of 21-year-old Monegasque team mate Charles Leclerc who was unable to repeat his Bahrain Grand Prix pole of two weeks ago. Bottas, who won the season opener in Australia and leads defending champion Hamilton by one point in the standings, was the third different driver to take pole this season in three races. "The lap was OK, not completely how I wanted. Luckily it was good enough for pole," smiled the Finn, who pipped Hamilton by 0.023 seconds after setting a best time of one minute 31.547. "Lewis also managed to improve a lot during the qualifying and it was super-close." The pole was a first for Bottas since Russia last September and the seventh of his career. It was also his first in China where Mercedes have won five of the last seven races. Hamilton sounded happy just to be on the front row, despite six previous poles in Shanghai, after looking out of sorts in practice. "I didn't give up, I kept pushing right to the end. Big congratulations to Valtteri, he's been stellar all weekend and I've been struggling and fighting the car," said the Briton. "To be as close as we are at the end is fantastic. An incredible result for the team. There was a little bit more time left on the table there but that's cool, I'll try and get it tomorrow," added Hamilton. UNHAPPY VERSTAPPEN Ferrari had arrived in China as favorites after showing their speed in Bahrain, particularly on the straights, with Leclerc on pole and leading until a loss of engine power in the closing laps. While unable to match the quick-cornering Mercedes cars for overall pace in Shanghai, Vettel hoped to be closer on Sunday thanks to the track's main straight being more than a kilometer long. "I think there was maybe a little bit more but overall not enough to beat these guys today," said the 31-year-old German, a four times world champion. "If we get close we could have an advantage in a straight line." The top 10 positions went two-by-two in team order, with Red Bull's Max Verstappen and Pierre Gasly fifth and sixth and ahead of the Renault pair of Daniel Ricciardo and Nico Hulkenberg – the Australian just 0.004 ahead of the German.
