Mercedes-AMG could use electric turbos

Mercedes-Benz is joining Audi in analyzing electric turbochargers for its production cars. But while Ingolstadt will roll out its first e-turbo in its A8 luxury sedan, Stuttgart is studying the technology for use in small performance cars, like the A45, CLA45, and GLA45 AMG models. Auto Express spoke to Mercedes-AMG compact car boss Steffen Jastrow about the cutting-edge tech, which reduces turbo lag, improves fuel economy, and occupies less space under the hood than a standard turbo. "Of course we need more power for the next-generation of cars, but electrification does not mean we have to use an electric drivetrain." Jastrow said. "They have to be faster and e-turbos are an option. We use them in motorsport, but the technology has to be payable for the customer." As AE tells it, bringing the price of e-turbos down from the A8's luxury car level to the relatively affordable sums demanded by compact AMG models will still take some time. So don't count on seeing a Mercedes with an electric turbocharger until the new A-Class arrives in 2017, at the earliest. Related Video:

Mercedes-Benz releases US-spec 2014 Sprinter details

Last week, Mercedes-Benz released the details for the updated 2013 Sprinter intended for global markets, but this week it has announced what changes are being made to the US-spec version of the van for the 2014 model year, including the Freightliner model. As expected, most of the changes made to the European model will be present on the 2014 Mercedes-Benz Sprinter when it goes on sale in the US, which is expected to be this fall.
The biggest difference between the Sprinter announced last week and the one headed to our shores is what is found under the hood. While European Sprinters will come with diesel engines and offer the availability of a supercharged four-cylinder gasoline or CNG engine, US Sprinters will still offer the 3.0-liter V6 BlueTEC diesel. This year's Sprinter now comes standard with a new base engine, the 2.1-liter four-cylinder BlueTEC diesel. This smaller engine will produce 161 horsepower and 265 pound-feet of torque, and will be paired to a seven-speed automatic transmission; the optional 3.0 V6 puts out 188 hp and 325 lb-ft of torque, and will be mated to a six-speed auto.
Fuel economy for the new Sprinter has not been announced, but Mercedes-Benz has made numerous changes with the goal of improving efficiency. To this end you'll find a new, low-friction rear axle and the optimization for the generator, fuel pump and power steering pump.

F1's Sebastian Vettel, Lewis Hamilton face off again in Austria

SPIELBERG, Austria - Sebastian Vettel celebrated his 30th birthday on Monday, but it can be safely assumed that Lewis Hamilton will not be bringing any gifts to Austria this weekend. After the "road rage" of Azerbaijan two weeks ago, the Formula One title rivals head to the bucolic surroundings of the scenic Red Bull Ring and its backdrop of hills and forests, with controversy still simmering. Vettel, Ferrari's championship leader, had risked a heavy penalty for his moment of madness in driving into Hamilton's Mercedes behind the safety car in Baku but instead the German arrives in Austria with no further sanction and the matter officially closed. Vettel has had to accept full responsibility, and apologize to Hamilton, and will have to stay on best behavior with a race ban looming if he collects any more penalty points on his license this weekend. The FIA said Monday's meeting was attended by top officials including race director Charlie Whiting and safety director Laurent Mekies. "Following detailed discussion and further examination of video and data evidence related to the incident, Sebastian Vettel admitted full responsibility," the FIA said. "In the heat of the action I then overreacted, and therefore I want to apologize to Lewis directly, as well as to all the people who were watching the race. I realize that I was not setting a good example." A formal apology was published on Vettel's personal website. "During the re-start lap, I got surprised by Lewis and ran into the back of his car. With hindsight, I don't believe he had any bad intentions," he said. "In the heat of the action I then overreacted, and therefore I want to apologize to Lewis directly, as well as to all the people who were watching the race. I realize that I was not setting a good example. "I love this sport and I am determined to represent it in a way that can be an example for future generations." But the incident, the sport's major talking point post-Baku, is unlikely to die down immediately even if Mercedes say they have moved on. Hamilton, for one, has said nothing. But he has kept social media buzzing with news he had "liked" a fan's supportive post on Instagram that said the Paris decision had sent the message that "you can do whatever you want on track, smash into each other but if you suck up and just apologize and you get away with it." Hamilton is now 14 points behind Vettel after eight of 20 races, with a loose headrest costing the Briton victory in Azerbaijan.
