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.

Infiniti went out of its way to make the QX30 not a Mercedes

You can complain all you want about perceived badge engineering when a company (like Mercedes-Benz) sells a platform to another brand (such as Infiniti). The reality is that most buyers won't know the difference, and they won't even realize their Infiniti is really a Mercedes underneath or that their neighbor's GLA has the same basic parts as the QX30 they just bought. What's weird to me isn't that sameness, but the places where the two cute little utes differ. These two vehicles, which are more like tall hatchbacks, use the same Mercedes 2.0-liter turbo four and seven-speed dual-clutch transmission. Infiniti adds its own throttle and transmission calibrations. The suspension design is the same, although there are tuning differences. Both come standard with front-wheel drive, with all-wheel drive an option. Fuel economy matches for the FWD models, while the AWD Infiniti lags behind the Mercedes for some reason. So they're very similar despite their different looks. And design makes sense as a point of differentiation. Frankly, they go further than a lot of vehicles on shared platforms do – further, in fact, than the upcoming Nissan Navara-based Mercedes X-Class pickup does. The QX30 has its own sheetmetal and glass to separate it from the GLA-class. You probably think one looks better than the other. If you know where to look, the signs of sameness are obvious. Most major systems and pieces are shared, like the steering wheels (with different center covers), most switchgear, and things like interior and exterior door handles. Shared parts are fine as long as the parts are good ones. On that note, how many Tesla buyers realize their steering column and stalks, plus the window switches, come from Mercedes? And does that actually matter? We'd argue no. About those differences. Many are functional, like the fact the Infiniti does not carry over the Benz's Brake Hold feature – when you roll to a stop in the GLA (or any other Benz), pressing the brake pedal firmly applies the electric parking brake until you hit the gas to move again. The QX30 has an electric parking brake, but no Brake Hold feature. Someone used to driving Mercedes models will look a bit silly standing on the brake pedal to no effect. Ask us how we know. The Mercedes gauge package is carried over, but with the Infiniti font. Makes sense, although it's off-putting at first if you've seen the original, prompting a weird deja vu. Circular dash vents are replaced by rhomboid ones.

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.
