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.

2019 Autoblog Technology of the Year finalists revealed

Every fall, we line up a range of new models with the latest and most compelling automotive technology from the past year. We test everything from semi-autonomous systems like Tesla's Autopilot to trick suspension setups like the Multimatic spool-valve shocks on the Chevy Colorado ZR2. We spend months paring down the list to a small group of contenders. After testing, dinner and healthy debate, we tally up the votes and name our winner. For Autoblog's 2019 Technology of the Year Award, our three finalists are the Cadillac CT6 with Super Cruise, the Infiniti QX50 with Variable Compression Turbo and the Mercedes-AMG E 53 with EQ Boost. Super Cruise is an advanced SAE Level 2 semi-autonomous system, though Cadillac (unlike some of its rivals) is reluctant to push that point. Cadillac would like you to think of this as an advanced driver assistance feature rather than a semi-autonomous system. Super Cruise allows completely hands-free highway driving. Thanks to a driver-facing camera, the system forces the driver to keep his or her eyes on the road even if hands are off the wheel. Although the CT6 is being discontinued, look for Super Cruise to make its way to other Cadillacs soon. VC Turbo is a little more complicated. Basically, Infiniti's 2.0-liter turbocharged inline-four can vary the compression ratio on the fly. In general, turbocharged engines are more efficient than naturally-aspirated engines when on boost, but can perform worse at low revs. VC Turbo allows for a best-of-both-worlds situation, increasing the compression at low revs and backing it off once the turbo spools up. The best part is that it does so seamlessly, with only a dash readout letting you know what's going on under the hood. Our third finalist is the EQ Boost 48-volt system in the Mercedes-AMG E 53. Like VC Turbo, EQ Boost does a lot just beneath the surface. Mercedes has developed a new turbocharged 3.0-liter inline-six and paired it with a small electric motor. While the car can't run on electricity alone, the motor helps improve both efficiency and performance, smoothing shifts and filling in low-end torque before the turbos spool up. Think torque fill, similar to a McLaren P1. Who can complain about better fuel economy and more torque? Look for the 48-volt system to make its way into most of the Mercedes-Benz lineup. The winner will be revealed next week on Autoblog, and we'll present the award Jan. 15 at the Detroit Auto Show. Related Video:

Weekly Recap: Ferrari looks to reclaim old success with new manager

Clearly, Ferrari doesn't race for fourth place, and this week, major changes continued at the Scuderia. It was a rough year for Ferrari, and the Scuderia conducted its season-ending tests in Abu Dhabi this week with a view toward a fresh start in 2015 with new leaders and a new ace driver. Though plenty of other Formula One teams were disappointed with their finishes in 2014, Ferrari was perhaps the most eager to put this season in its rear-view mirror. The Scuderia finished a distant fourth in the Constructors standings with 216 points, well behind No. 1 Mercedes (701 points), and Ferrari failed to win a single race as the Silver Arrows dominated the grid. It was an especially bitter pill for a team that claims 16 Constructors championships and 15 Drivers titles – the most in history – and is the only surviving team from F1's first season, 1950. Clearly, Ferrari doesn't race for fourth place, and this week, major changes continued at the Scuderia. Ferrari named Philip Morris executive Maurizio Arrivabene as team principal. He replaced Marco Mattiacci, who held the job for only seven months after taking over for Stefano Domenicali, who resigned in April amid the Scuderia's early-season struggles. Phillip Morris (through its Marlboro brand) is a key Ferrari sponsor, and that played a role in Arrivabene's ascension. Still, he's no stranger to F1, and has been intimately involved in the Ferrari-Marlboro partnership. He also has served as the sponsors' representative on the FIA's F1 Commission since 2010. In a statement, new Ferrari chairman Sergio Marchionne said: "We decided to appoint Maurizio Arrivabene because, at this historic moment in time for the Scuderia and for Formula One, we need a person with a thorough understanding not just of Ferrari, but also of the governance mechanisms and requirements of the sport." Arrivabene's background is primarily in marketing and communication, and most recently he held the title of vice president of consumer channel strategy and event marketing for Philip Morris. He has been with the company since 1997. Arrivabene now leads a team that's rife with change. Marchionne took over in October when longtime boss Luca di Montezemolo quit in a disagreement about Ferrari's future, and the company itself will be spun off from parent Fiat Chrysler Automobiles in 2015.
