Aston Martin and Mercedes-AMG bicycles: Luxury branding has no bounds

Luxury automobile companies are never quite satisfied with building high-end cars. They often stray into other types of branded merchandise that can have little to do with cars, such as the BMW Active line of clothing and accessories. Splitting the difference between branded merchandise and actual vehicles are these two limited-production bicycles from Mercedes and Aston Martin. The bike above is a collaboration between Mercedes-AMG and German bicycle brand Rotwild, a builder that has been around since 1996, according to the company's website. The bicycle in question is the R.S2 "Beast of the Green Hell." It's inspired by the Mercedes-AMG GT R sports car that was promoted with the same nickname. It uses a carbon frame and wheels, as well as disc brakes. It's also painted in green and black to match the Green Hell Magno color available on the GT R. Only 50 of them will be built, and each will carry a pricetag of over ˆ7,000, or nearly $8,300 at current exchange rates, including tax.

The bike is called the Fascenario.3 Aston Martin Edition, and it will be a bit less rare than the Mercedes bicycle, with 107 total units. It's still a cool vehicle, though, featuring a carbon frame and wireless shifters. In total it weighs 13 pounds. It does lack the disc brakes of the Mercedes bicycle, though. Pricing hasn't been announced for the Aston Martin bike, but don't expect it to be cheap.

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 to roll out C63 AMG late in 2014 with 4.0L V8

The new 2014 Mercedes-Benz C-Class is upon us, launching initially in North America with turbocharged four-cylinder C300 4Matic and six-cylinder C400 4Matic flavors. But that's only the tip of the proverbial iceberg when it comes to the vast array of powertrain configurations that will be offered in the new C-Class in markets around the world. Orders will soon be rolling in for gasoline, hybrid and diesel engines with four, six or eight cylinders, driving the rear wheels or all four, with the seven-speed automatic transmission soon to be replaced by a new nine-speed unit. But what enthusiasts are really looking forward to is the next C63 AMG.
As BMW has done with the M3 (and new M4), Mercedes has gradually ratcheted up the cylinder count in its AMG C-Class, graduating from the 3.6-liter V6 in the original C36 AMG to the 4.3-liter V8 in the C43 AMG, then the 5.5-liter V8 in the C55 AMG before going the distance with the sublime 6.2-liter V8 in the C63 AMG. Like its rivals, Mercedes is expected to use turbochargers as a replacement for displacement in the next model, but unlike its Bavarian rival, it won't be losing any cylinders in the process.
Skipping the 5.5-liter twin-turbo V8 that has gone on to power other AMG models, the next C63 AMG is still expected to introduce a new 4.0-liter twin-turbo V8 producing between 450 and 500 horsepower. It'll also reportedly keep the same seven-speed automatic transmission (instead of switching to the new nine-speed), but the jury's still out on whether it'll come with rear- or all-wheel drive (or offer buyers the choice). The downsized V8 - codenamed M177 - is then expected to find its way into other models, but the C-Class will be the first to get it when it arrives before the end of the new year ahead.
