Mercedes testing C-Class plug-in hybrid modes in Germany

Testing appears to be underway for what would be the first Mercedes-Benz C-Class with a hybrid powertrain. We can see a pair of the prototypes undergoing testing in Germany, with one, a C-Class Wagon, still heavily clad in camouflage and featuring a more noticeable outlet on the passenger side of its rear bumper.
There's also a more production-looking sedan, which features a not-so-discreet flap over its rear-bumper outlet. It's difficult to speculate on power outputs for this fuel-sipping C-Class, although our spies seem to think that this car will feature some combination of a four-cylinder gas engine with an electric motor, although just which four is unclear (note, we wouldn't mind if MB fit its 2.0-liter turbo with some batteries and motors). Regardless, the four-pot/electric motor seems like a pretty reasonable combo, although it probably means that Mercedes won't be challenging the six-cylinder-powered system of the BMW ActiveHybrid3 any time soon.
When the plug-in C-Class arrives later this year as a 2015 model, it will likely offer a full range of driving modes, including both gas or electric, only, as well as a more traditional hybrid mode.

Lewis Hamilton wins British GP, slashes Vettel's lead to 1 point

SILVERSTONE, England - Lewis Hamilton won his home British Grand Prix for the fourth year in a row on Sunday, while a penultimate-lap puncture slashed Sebastian Vettel's championship lead to a single point. The Briton's drive from pole to flag on an overcast afternoon was lonely, uneventful and dominant - in complete contrast to his Ferrari rival's afternoon - with Mercedes teammate Valtteri Bottas finishing 14 seconds behind to secure the one-two. "The support has been incredible this weekend. I am so proud I could do this for you all," said Hamilton, who threw himself into the fans for some crowd surfing after the podium celebrations. "The team were faultless this weekend, Valtteri did an incredible job as well, so it's the perfect weekend for us." Far behind in his wake, as Hamilton cruised to a 57th career win and soaked up the applause from an army of flag-waving fans, came sudden drama. Vettel, who had battled on worn tires but looked like securing the final podium position until the blowout, finished seventh after an emergency pit stop with a shower of sparks from the wheel rim. "There was no sign of that happening," said Vettel over the team radio. "There were vibrations but I had it for 20 laps and it didn't get massively worse. The tires didn't look great but they never look great." The German's Finnish teammate Kimi Raikkonen, who had been second before also being hit with a late puncture that sent Bottas and Vettel ahead of him, took third. At the halfway stage of the 20-race season, Vettel has 177 points to Hamilton's 176 with Bottas on 154. Hungary, a circuit where the Briton has won five times before, is next up. Hamilton became only the third driver, after his late compatriot Jim Clark and Frenchman Alain Prost, to win the British Grand Prix five times and the first to take four successive victories at Silverstone. Clark won four in a row in the 1960s, but one was at Aintree and another at Brands Hatch. Red Bull's Max Verstappen finished fourth, ending a run of retirements, with Australian teammate Daniel Ricciardo fifth after fighting through the field. Germany's Nico Hulkenberg was sixth for Renault and Force India pairing Esteban Ocon and Sergio Perez were eighth and ninth with Brazilian Felipe Massa securing the final point for Williams. Jolyon Palmer's miserable run continued, with Britain's only other driver on the grid failing to make the start after his Renault broke down on the formation lap with a brake failure.

Next Aston Vantage will be the only way to get an AMG V8 with a stick

With only a few exceptions, most of them factory customs, AMG hasn't built cars with manual transmissions. It just isn't the way things are done in Affalterbach. But now that Mercedes's in-house speed shop will be supplying engines to Aston Martin, the world will be treated to cars with three pedals and overengineered German V8s wrapped in a pretty British package. We're into it. The news comes from Car and Driver, which spoke to Aston Martin CEO Andy Palmer about the new Vantage among other things. Palmer confirms to C/D that the Vantage will continue to offer manual and automatic transmissions when the next-gen car arrives featuring the AMG 4.0-liter twin-turbo V8. In its most potent form, the eight-cylinder makes 503 horsepower and 479 lb-ft of torque in the AMG GT S. Figure on a little more from the Aston-ized version, just for fun. The current V8 Vantage GT makes 430 hp and 361 lb-ft from its naturally aspirated 4.7-liter. While some may lament the new engine's forced induction, that added power and the thoroughly modern behavior of the AMG engine should be welcome. While the AMG V8 is currently only planned to go into Aston's entry-level car, C/D does mention a possibility of it (and perhaps its three-pedal transmission) making its way into other cars as an economy option for certain markets. If a V8 DB11 were to be offered, don't expect it to show up here, though. There's also no word on who will supply the manual for the AMG-Aston mashup, but it likely will be a transaxle like the current Vantage. Ex-factory manual AMGs aren't totally unprecedented. Pagani has built some three-pedal cars with its massaged AMG V12s. Compared to those, however, these manual Vantages can be considered mass-production cars. And really, any increase in the number of sticks mated to AMG engines can only be a good thing.
