Daimler and Volvo could jointly develop internal combustion engines

BERLIN — Luxury German carmaker Daimler and Volvo, owned by China's Geely, are considering cooperating to cut the costs of developing combustion engines, a magazine reported on Sunday, citing unnamed company sources. The Automobilwoche weekly cited a Volvo manager as saying there were initial talks with Daimler, but no concrete plans, while a company spokesman said it was too early to talk about firm projects, although it was not excluding anybody. A Daimler spokesman said the company's cooperation with Geely, which owns a 10% stake in the German carmaker, was developing in a positive way, but declined to comment further. Global tariffs, accelerated by a trade war between China and the United States, as well as higher investment requirements for electric and autonomous vehicles, are forcing carmakers to seek new ways to cut and share costs. In October, Volvo said it would merge its engine development and manufacturing assets with those of Geely, creating a division to supply in-house brands and also potentially others with next-generation combustion and hybrid engines. Automobilwoche said this new division would start operating by the end of March, which could be a possible starting point for cooperation with Daimler, while a further step could be a partnership to develop electric power trains. Geely and Daimler have said they plan to build the next generation of Smart electric cars in China through a joint venture and the two companies are also cooperating on a premium ride-hailing service in China. Geely bought Volvo Cars in 2010 from Ford, allowing the Swedish brand to operate on an arms-length basis. But in recent years, it has deepened cooperation between the two brands. Volvo already supplies engines to some Geely-branded vehicles, sharing technology through Geely's Lynk brand. Both companies share and develop common vehicle platforms.

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.

2013 Mercedes-Benz SLS AMG GT Coupe

Mercedes-Benz upgraded its SLS flagship Coupe and Roadster for the 2013 model year, and the changes are marked with them new "GT" nomenclature. Both SLS models arrive with a retuned naturally aspired 6.2-liter V8 delivering 583 horsepower and 479 pound-feet of torque (the horses are up from 563, but the torque remains the same) mated to a revised seven-speed AMG Speedshift dual-clutch gearbox. Rounding out the mechanical upgrades is a redeveloped AMG two-mode adaptive suspension. Physically, the revised models are differentiated by their new "GT" badging, darkened headlight/taillight buckets, red brake calipers, unique wheel colors and high gloss finish on the front grille, exterior mirrors and hood/fender fins. Inside the cabin are new red seatbelts, Alcantara upholstery and contrasting red stitching.
As it is nearly impossible to experience the aluminum gullwing beast on public roads, Mercedes invited out to Southern California's Willow Springs to wring out the 2013 SLS GT Coupe on a racing circuit.
