2014 Mercedes-Benz B-Class ED has 87-mile range, 84 MPGe

Well, that extra weight had to be felt somewhere. With Mercedes-Benz getting ready to start US sales of its B-Class Electric drive this summer, the big question was how well its range would stack up against other electric vehicles sold in the States. Turns out, the Benz is a bit of a juice hog. Let's say up front that the 87-mile single-charge range of the Mercedes-Benz actually stacks up nicely against its competition, since that distance puts the new model right in line with the Nissan Leaf and BMW i3 (we'll ignore the Tesla Model S for a second, here). You can find the numbers at the US Department of Energy's FuelEconomy website. As far as miles per gallon equivalent ratings, though, the Benz's steel frame makes it come up short, as it's about 1,300 pounds heavier than the carbon-fiber-body i3 and about 600 pounds heavier than the Leaf. The B-Class EV has a bigger battery than the i3 or the Leaf (36 kWh compared to 22 kWh for the i3 and 24 kWh for the Leaf) and that's one reason the car gets an 84 MPGe rating, which is about 26 percent less than the Leaf's and 32 percent less than the i3's. But at least the local utility companies will be happy. Mercedes-Benz priced the 177-horsepower B-Class ED in April at $41,450, or $100 more than the i3.

Aston Martin tipped for F1 return with Red Bull, Mercedes

Aston Martin could be plotting a return to Formula One for the first time in over half a century. And not as a backmarker, either. That is, at least, if the latest rumors materialize. While most automakers that participate in F1 do so as either a team owner (like Ferrari and Mercedes) or as an engine supplier (think Renault or Honda), the rumored Aston Martin deal would take a different approach. According to Autosport, the proposal would have the Red Bull Racing team run Aston Martin branding – but not its engines. Those would be provided by Mercedes, just like the engines in the British marque's upcoming slate of road cars. In that regard, the deal would not be unlike the one which Red Bull currently has with the Renault-Nissan Alliance, which sees the team running Renault engines and Infiniti branding. Andy Palmer was a pivotal figure in brokering that unusual arrangement when he was working for Carlos Ghosn, and is now tipped to be brokering a similar deal in his new capacity as Aston Martin's CEO. Though Aston has found glory in sports car racing (including Le Mans and its various associated series), it was never much of a contender in grand prix racing. It competed in a handful of races in 1959 and 1960, but never achieved results worth bragging about. Aston was rumored to be plotting a return when David Richards sat as chairman of the company, having run Aston's racing program as well as Honda's F1 team previously. Those rumors, however, never materialized. Whether this time 'round gains any traction remains to be seen - Aston Martin declined to either confirm or deny the reports when reached for comment by Autoblog. Red Bull has been growing increasingly dissatisfied (and increasingly vocal about its dissatisfaction) with Renault engines over the past couple of seasons. Though the two parties won four back-to-back world titles together, things took a noticeable step backward after the new turbo engine regulations took hold for the 2014 season. Nissan/Infiniti and Red Bull are contracted to continue collaborating until the end of next season. After that is when the new Aston deal could take hold, and Mercedes is reportedly keen on the idea so that it could add another customer to its F1 engine supply business and offset the costs of development. That could effectively prove the end of Renault in F1 (at least for the time being). Aside from Red Bull, the French automaker currently supplies only that outfit's sister team Toro Rosso.

Mercedes spotted testing hardcore AMG GT at the 'Ring

Mercedes has showcased its new AMG GT in both base and S trims, it's rolled out the GT3 racing version and the Formula One safety car. But we're only beginning to see the extent of the variants that the German automaker is expected to spin off of its new sportscar. And here is the latest. Spied undergoing testing at the Nurburgring is what appears to be an even more performance-focused version of the Mercedes-AMG GT. It seems to be packing an upgraded aero kit – complete with front splitter and rear wing – as well as larger rolling stock. You can bet there's an even more potent version underhood of the 4.0-liter twin-turbo V8 that's already producing over 500 hp in the existing model. Whether Affalterbach deems it worthy of the Black Series label or not is another question, but what's clear is that AMG is gunning for the Porsche 911 GT3 with the performance model you see here – however disguised it may be from our prying eyes.
