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.

Is Audi getting complacent and suffering from brain drain?

The argument is made in a Reuters article: Audi is falling behind other luxury brands, such as Mercedes-Benz and BMW, due to a lack of research-and-development spending and "brain drain," or the migration of top executives and R&D chiefs to other parts of the Volkswagen Group. Reuters notes that Audi's current R&D chief is the third in 16 months.
Audi, which contributed to 40 percent of VW Group's $11.6 billion in profit the first nine months of the year, is delivering cars at a record pace: 1.31 million were delivered from January to October 2013 versus BMW's 1.35 million. Yet Audi, Reuters reports, doesn't have a halo car akin to BMW's new electrified i3 and i8 or an answer to Mercedes' plug-in-hybrid S-Class, and the R&D spending at Audi is less than BMW and Mercedes by a fair margin. It's noted in the article, however, that Audi benefits from other R&D spending within VW Group.
Reuters mentions that BMW "trumpets its new 'i' series" and the new Mercedes CLA and GLA ranges are winning "rave reviews" as part of its argument that Audi's recent lack of technological innovation could hurt future sales. Those cars do pack tons of new technology, some of which are firsts for mainstream production cars. But last time we checked, the i3 could be causing BMW's stock to slide, the CLA isn't receiving the rave reviews that Reuters would have you believe and the GLA hasn't been reviewed yet.

Red Bull may seek engines from Ferrari after Mercedes snub

Red Bull and Renault's fractured relationship is pushing the Austrian F1 team to find a new engine provider. But after a trip across the German border to chat with Mercedes-Benz proved fruitless, the team is apparently set to head across its home country's southern border, and into Italy. Yep, Red Bull Ferrari could be a thing next season. According to RBR boss Christian Horner, the company is just doing "necessary due diligence" in contacting other engine suppliers, although he's willfully admitted to Germany's Bild newspaper that the "idea of Mercedes is finished," BBC Sport reports. It wasn't so much that Mercedes and Red Bull couldn't come to financial agreement – Red Bull owner Dietrich Mateschitz views throwing money into F1 in much the same way you or I toss pennies into the mall fountain – but rather that the Germans had no interest in supplying the best engines on the grid to the factory team's perennial rival. BBC Sport seems to think that fact, along with what the outlet calls Red Bull's "antagonistic" relationship with engine suppliers, killed the Mercedes deal. Honda and RBR aren't likely to happen either, thanks to McLaren (not that we think Red Bull would approach the Japanese, which have struggled mightily all season long). By process of elimination, that just leaves Ferrari. Scuderia Ferrari Team Principal Maurizio Arrivabene confirmed that his team can accommodate Red Bull's engine needs, and that he wasn't concerned with the idea of a Ferrari engine in an Adrian Newey-designed body. "In theory they have big names, with Newey as chief designer and it is easy to think that if you give them the engine they will build a scary chassis, which means they will be really competitive," Arrivabene told BBC Sport. "Concerning my team, my engineers and aerodynamicists know their own jobs. For that reason I don't have a problem, and competition is nice when you have a stronger competitor." "This doesn't mean tomorrow morning we will give our engines to Red Bull or Toro Rosso," Arrivabene added. And it's that statement we'd suggest remembering. There are, after all, still seven races left in the 2015 season, which is quite a lot of time for new and different developments within the sport's notoriously gruesome political process. In other words, don't count on an announcement from any team or manufacturer for at least a few more races. Related Video:
