Aston Martin Vantage vs. Mercedes-AMG GT C Review | Translating German into English

GROssBRITANNIEN — No car matches the new Aston Martin Vantage as closely as the Mercedes-AMG GT, the two sharing both their 4.0-liter twin-turbocharged V8 and electrical architecture while competing for the same market niche. So, of the many challenges Aston Martin faced when developing it, ensuring that the Vantage had a unique identity must have weighed more heavily than any other. The added spice to this confrontation is the GT's status as halo model for AMG. Meanwhile, Aston Martin's brand identity, built on the sharp-suited machismo embodied by a certain big-screen spy, is a make-or-break issue for the company. The identity problem has fascinated me since the AMG deal was first announce in 2013. So exploring the Vantage on British roads with the GT literally filling the mirrors is a big deal. Now, finally, we have directly competing products with which to explore the theory. And there's much to like in both, not least of which is that common powerhouse of an engine. While they don't share a platform, both use the classic front-engine, rear-drive, transaxle layout, with traditional driving manners to match. Some quick number-crunching as an appetizer: The AMG GT C you see here has the dry-sumped M178 derivative of the V8, with 550 horsepower and 501 pound-feet of torque, driving the rear wheels through a transaxle-mounted, seven-speed dual-clutch transmission and fully active electronic locking differential. It's 179 inches long, weighs 3,748 pounds and will clear 0-60 mph in 3.6 seconds en route to 197 mph. The Vantage has the wet-sumped M177 version of the same engine, as featured in countless AMGs and shared with the DB11 V8. It makes 503 hp, 505 lb-ft and drives the rear wheels through a transaxle-mounted, eight-speed automatic gearbox and fully active electronic locking differential. Sounding familiar? It's comparable in overall length but a couple of inches longer in wheelbase, and weighs pretty much the same as the GT C, give or take a few pounds. It hits 60 in 3.5 seconds and tops out at 195 mph. Both have adaptive dampers and a variety of driver modes, both are built from aluminum and both are at the sportier end of the GT spectrum. The two U.K.-market cars you see here cost just more than $180,000 with options. Pretty darned close, then. Numbers are one thing.

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.

Mercedes previews new S-Class convertible

Mercedes keeps on expanding its flagship S-Class with more models, and will soon add one more to the roster. But before it does, it's giving us this teaser of what's to come with an advanced look at the upcoming new S-Class Cabriolet. The convertible model will be based closely on the S-Class Coupe we already know, only with a folding roof. Expect that dropping top to be constructed of several layers of fabric (as opposed to a folding metal top) with a glass rear window (instead of plastic) to keep it luxuriously isolated and insulated from the outside world when it's up, and let the wind and sunshine in when down. The Cabrio will bring the array of body-styles in the S-Class range up to six, with the convertible joining the existing coupe and four wheelbase lengths of sedan. Expect powertrain options to closely mirror those of the coupe, including S550, S63, and eventual S65 AMG models driving the rear wheels or all four. Slotting in above the E-Class Cabriolet, the new convertible S-Class will be Daimler's "first luxury four seater cabriolet since 1971." It'll compete in rather rare company against the likes of the Bentley Continental GTC, Aston Martin DB9 Volante, Maserati GranTurismo Convertible, and even the upcoming new Rolls-Royce Dawn when it arrives. And judging from the timing of this preview rendering's release, we anticipate it'll arrive soon. Related Video:
