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.

Genesis G70 vs sport sedan rivals: How it compares on paper

We got our first look at the Genesis G70 sport sedan today. We think it looks good, with enough ties to its fellow Genesises (Geneses?) to further establish the brand and just enough distinction to help it stand out from the crowd. But ah yes, the crowd. Although Genesis didn't release the G70's full spec sheet, it revealed just enough for us to start sizing it up to its future competition. There are certainly others with which to compare (Lexus IS, Cadillac ATS, Alfa Romeo Giulia, Jaguar XE just to name a few), but we decided to take a look at the best sellers and most competitive luxury sport sedans. (And hey, if you like this, we can always do a follow up) So, here we have the Genesis G70 vs BMW 3 Series vs Audi A4 / S4 vs Mercedes-Benz C-Class vs Infiniti Q50. Nothing like a good chart to dig your teeth into on a Friday. Note that we only compared those models that line up with the G70. So, we left out the BMW 320i and Audi A4 Ultra entry level models as well as the Q50 3.0t mid-grade model that's considerably cheaper than the German performance upgrade models we listed. All 0-60 figures are rough estimates based on several sources, models/drivetrains and OEM figures.

Maybach and Aston Martin alliance talks fall apart

If you have, like us, been salivating at the notion of a new generation of Maybach and Lagonda ultra-luxury crafts built by Aston Martin, we've got some bad news: According to reports emanating from Germany, talks between AML and Daimler have broken down.
The proposal under negotiation would have seen Daimler outsourcing production of the next family of Maybach models to Aston Martin, which in return would benefit from Mercedes-Benz platforms and engines - not only for its svelte GTs, but also for its own future Lagonda line of limousines and luxury SUVs. That, and a boatload of money - or at least that's what AML was reportedly seeking, an issue that served as the stumbling block over which the deal reportedly collapsed.
That's not to say the two parties couldn't still reach some sort of a compromise, but short of that, Daimler may opt to either shut down Maybach altogether, find another partner, or take another stab at building new models internally.
