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:

First Mercedes B-Class Electric Drive rolls off line, coming to US soon

Mercedes-Benz is about to give Americans another choice of battery-powered vehicle. Offering more all-electric range than the Nissan Leaf or BMW i3, and with a smaller price tag than the Tesla Model S, the B-Class Electric Drive is officially set to arrive in the US this summer. Indeed, the first examples have begun rolling off the production line in Rastatt, Germany. Featuring drivetrain parts from Tesla Motors, the luxury compact hits all the performance parameters mentioned during its debut at last year's New York Auto Show. For a refresher, that's a single-charge range of 200 kilometers (124 miles) along with a 0-to-100 kilometer-per-hour (62 mile-per-hour) sprint in a respectable 7.9 seconds. These achievements comes courtesy of a 28-kWh lithium battery located in the floor of the passenger compartment and a 132-kW (177-horsepower) motor powering the front wheels. Torque specs for the unit seemed to have increased somewhat and are now given as 340 Newton meters (250.77 pound-feet). It boasts an 11-kW charger and can add as much as 62 miles of range to a deleted battery in an hour and a half. Sadly, it is not Supercharger compatible. The B-Class Electric Drive, which is built on the same production line as the gasoline-powered version, is going to go on sale in Europe around the end of the year and will also come in a right-hand drive version for other markets in 2015. Although pricing has not yet been announced, Mercedes execs expect it to be quite competitive with the BMW i3. Scroll below for the press release (Google translated from German). Model offensive: Mercedes-Benz launches first major series for electric cars - the start of production at Mercedes-Benz in Rastatt: B-Class Electric Drive begins For the first time large-scale production of Mercedes-Benz models with internal combustion engine and electric drive on the same line Stefan Abraham: "With the B-Class Electric Drive we are expanding our production portfolio at the Rastatt plant is a highly innovative drive variant." In the Mercedes-Benz plant in Rastatt today through the first B-Class Electric Drive off the line. This makes Mercedes-Benz models are produced with internal combustion engine and electric drive on the same line at the site for the first time. The B-Class Electric Drive is based on the Mercedes-Benz front-wheel drive architecture of the new Mercedes-Benz compact car generation and uses the modular component kit.

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.
