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.

Gordon Murray, F1-driven production and .. the Pontiac Fiero

Gordon Murray's design and engineering chops are unquestionable. But does his carmaking approach owe something to the short-lived Pontiac Fiero, a scrappy little car program that emerged from GM against serious resistance? Murray had a Formula One career that ran from 1969 to 1991, with stints at Brabham ('69 to '86) and McLaren ('87-'91), that resulted in several shelves' worth of trophies for the cars he was instrumental in designing. He moved on to McLaren Cars, the consumer side of things, where, during his tenure from 1991 to 2004, he helped design the McLaren F1 and the Mercedes-Benz SLR McLaren, two cars that took learnings from his two decades in Formula One. What do all of these cars have in common? Three things: They are light. They were built in limited numbers. And they were (and are) exceedingly expensive—when the McLaren F1 debuted in 1994, it stickered at $815,000. Murray went on to establish Gordon Murray Design in 2007. GMD has created some interesting concept vehicles, such as the diminutive T.25 city car (94.5 inches long, 51.1 inches wide and 55.1 inches high), and the OX, a lightweight truck for the developing world that packs like an IKEA shelf and is working toward realization through a worthy crowdfunding campaign established by the Global Vehicle Trust. Now he has created a vehicle manufacturing company, Gordon Murray Automotive, that will use manufacturing methods that he developed under the moniker "iStream." Unlike a unibody, there are the "iFrame," a cage-like construction made with metallic components, and the "iPanels," which are composite. The panels aren't simply a decorative skin; they actually provide structure to the vehicle. Presumably this has something of the F1 monocoque about it. Going back to the three elements, (1) this arrangement results in a vehicle that can be comparatively light; (2) Murray has indicated that his manufacturing company will be doing limited-run production; and (3) to launch Gordon Murray Automotive they are going to be building a flagship model, about which Murray said, "With our first new car, we will demonstrate a return to the design and engineering principles that have made the McLaren F1 such an icon." Which seems to imply that it will be on the pricey side. According to the company's verbiage, "iStream forges an entirely new production method that defies conventionality with its Formula One-derived construction and materials technologies." It also sounds a whole lot like ...

NHTSA, IIHS, and 20 automakers to make auto braking standard by 2022

The National Highway Traffic Safety Administration, the Insurance Institute for Highway Safety and virtually every automaker in the US domestic market have announced a pact to make automatic emergency braking standard by 2022. Here's the full rundown of companies involved: BMW, Fiat Chrysler Automobiles, Ford, General Motors, Honda, Hyundai, Jaguar Land Rover, Kia, Mazda, Mercedes-Benz, Mitsubishi, Nissan, Subaru, Tesla, Toyota, Volkswagen, and Volvo (not to mention the brands that fall under each automaker's respective umbrella). Like we reported yesterday, AEB will be as ubiquitous in the future as traction and stability control are today. But the thing to note here is that this is not a governmental mandate. It's truly an agreement between automakers and the government, a fact that NHTSA claims will lead to widespread adoption three years sooner than a formal rule. That fact in itself should prevent up to 28,000 crashes and 12,000 injuries. The agreement will come into effect in two waves. For the majority of vehicles on the road – those with gross vehicle weights below 8,500 pounds – AEB will need to be standard equipment by September 1, 2022. Vehicles between 8,501 and 10,000 pounds will have an extra three years to offer AEB. "It's an exciting time for vehicle safety. By proactively making emergency braking systems standard equipment on their vehicles, these 20 automakers will help prevent thousands of crashes and save lives," said Secretary of Transportation Anthony Foxx said in an official statement. "It's a win for safety and a win for consumers." Read on for the official press release from NHTSA.

Automakers making the commitment are Audi, BMW, FCA US LLC, Ford, General Motors, Honda, Hyundai, Jaguar Land Rover, Kia, Maserati, Mazda, Mercedes-Benz, Mitsubishi Motors, Nissan, Porsche, Subaru, Tesla Motors Inc., Toyota, Volkswagen and Volvo Car USA.
