Next Mercedes-AMG E63 to produce around 600 hp

"Sources" have told Autocar that the coming Mercedes-AMG E63 will get "something in the range of" 600 horsepower from a "next step" development of the 4.0-liter, twin-turbo V8 currently in the C63 sedan. Since the standard E-Class isn't due for introduction until the 2016 Detroit Motor show, we're probably a year away from finding out if "something in the range of" actually means a square 600 hp when the car the AMG E63 is revealed. Right now the E63 S is powered by a 5.5-liter twin-turbo V8 it shares that engine with the CLS63, S63, SL63, and G63, and all but the G63 get 577 hp from that engine. The 4.0-liter V8 in the C63 S is rated at 503 hp in the S model, the same as the dry-sump version of that engine that gets 503 hp in the AMG GT. Point being the jump to 600 hp isn't outrageous, and would keep up with the numbers rumored for the next BMW M5. New turbos will likely be responsible for much of that power, with AMG's powertrain chief having told Road & Track that the present turbos are doing all the work they were designed for. Depending on where the much lighter AMG GT3 road car comes in, the next AMG E63 should be the most powerful V8 model in the range. There'll be plenty of other doodads besides, like a new nine-speed automatic, 84-LED adaptive headlights, remote controlled parking, smartphone-activated NFC-based unlock and vehicle start, Vehicle-to-X communication, adaptive cruise control that recognizes speed limit signs, and a massive advance in the suite of Mercedes Intelligent Driving features.

Mercedes releases first shot of AMG GT3

A week ago we got a rendering of the upcoming race-only Mercedes-AMG GT3, to be shown to the public for the first time at the Geneva Motor Show. Now, Mercedes has let loose a photo of the front of the car and it looks very serious, a trait undoubtedly helped by its link to the past: that grille motif goes straight back to the W154 Silver Arrows pre-war racer driven to the 1938 European Championship by Rudolf Caracciola. Those angry, angled and sunken headlights don't hurt, either. It will be ready in time for the 2016 GT3 season and come loaded with expectations, since the SLS AMG GT3 it replaces has been a victory machine around the world. Unlike that SLS, though, this car will spawn a hardcore road-going version - not to be called GT3 - with less weight and more power, armed to do battle with the coupe that comes first to mind when that alphanumeric is mentioned. With the way the AMG GT S already gobbles up circuits, we're prepared to be impressed by what comes next.

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.
