Recharge Wrap-up: Mercedes B-Class Electric Drive is a rock star, FedEx tests electric trucks

The Mercedes-Benz B-Class Electric Drive is in a new music video for I Lived by OneRepublic. The band's singer, Ryan Tedder, has also been brought on as a brand ambassador for the German automaker. OneRepublic will also be performing the song at the Mercedes-Benz Media Night on the eve of the Paris Motor Show. No word if Mercedes plans to offer hordes of screaming teenage fans as an option package with the B-Class Electric Drive. See the video (the car shows up around the four-minute mark) or read more in the press release below. FedEx is testing converted electric delivery trucks with diesel range extenders. Looking to shrink its carbon footprint, the company has converted a handful of trucks as part of a pilot program. In addition to battery packs, each truck is equipped with diesel turbine generators (supplied by Ian Wright's company, Wrightspeed) to provide electricity when the battery is depleted. Because the diesel motors aren't powering the vehicle directly, they can continuously run at their most efficient speed, making the trucks about twice as efficient as those powered by traditional means.

The fuel economy gains depend on the particular version of the truck, but the biggest improvement will likely come from the 3.5-liter V6 and the 2.7-liter EcoBoost V-6. Automotive News predicts the F-150 SFE to be rated at 21 mpg city/28 highway/23 combined, which are identical figures to the Ram 1500 EcoDiesel. The result could be a noteworthy fuel economy battle between Ford and Ram trucks. Learn more at Automotive News. The US Department of Energy is providing $25 million in funding toward reducing the price of algal biofuels. The goal is to get the price of these renewable fuels below $5 per gasoline gallon equivalent (gge) by 2019, and less than $3 per gge by 2030. The money will fund projects to develop better algal cultures that produce biofuel and other useful bioproducts, and projects to boost biomass productivity. The DOE says it wants to help develop a "bioeconomy" that provides jobs, helps the environment and ensures energy security. Read more at Energy.gov. This content is hosted by a third party.

VW joins Daimler's protest of new A/C refrigerant as EU deadline for compliance passes

The case of Dupont and Honeywell's refrigerant R-1234yf is doing the exact opposite of keeping things cool. The two chemical companies have spent years and hundreds of millions of dollars developing R-1234yf to replace R-134a, the new refrigerant shown to be 99.7-percent kinder to the environment than the one it is meant to succeed. Part of that development has been years of testing by governments, outside safety agencies and automakers to approve the chemical for use in cars. It passed the protocols necessary for the European Union to declare that new and significantly revised cars from 2013 onward needed to use R-1234yf, and mandated that every car as of 2017 must use it.
Enter Daimler AG. The automaker created a head-on collision test with a B-Class at their Sindelfingen test track that would lead to the pressurized refrigerant being sprayed on the engine. The result in 20 out of 20 test was that the refrigerant burst into flames as soon as it hit the hot engine, while Daimler says that R-134a does not catch fire in the same test. Another unexpected result of the R-1234yf test was the release of hydrogen flouride, a chemical far more deadly to humans than hydrogen cyanide, emitted in such amounts that it that turned the windshield white as it began to eat into the glass.
Said a Daimler engineer in a Reuters piece, "It was scarcely believable. The most complicated lab tests conducted using the most sensitive measuring instruments around found nothing and all we do is drive a car around a couple of times, open a tiny hole in the refrigerant line and the next thing you know the car is on fire." So Daimler said it wouldn't use the refrigerant, and it recalled the cars it had already shipped with R-1234yf.

Aston Martin's deal with Mercedes-AMG more than skin-deep

Aston Martin is working on a raft of new models. But it's not going it alone: it has a technical partnership with Mercedes-AMG, the details of which have only been revealed in bits and pieces. If these latest spy shots are anything to go by, however, the arrangement could run deeper than anyone initially let on. Spied undergoing testing at the Nurburgring, this prototype for the upcoming successor to the Aston Martin DB9 is widely expected to be called the DB11 (10 is being used by James Bond's new ride). From the outside it doesn't look different than the previous versions we've seen running around, but this time we can also peer into the cabin, and that's where things start to get interesting. Despite the best arm-waving efforts by the development engineers, our spy photographers managed to snap a couple of shots of the interior. And though it looks far from being ready for production, the components we see appear to have been lifted from the Mercedes S-Class Coupe – particularly the steering wheel, digital instrument cluster, and almost the entire center console. This speaks to a deeper collaboration between the British and German automakers. The 4.0-liter twin-turbo V8 from the Mercedes-AMG GT, C63, and G500 4x42 is already being adapted for use in the next generation of Astons. Related Video:
