2014 Mercedes-Benz SLS AMG Black Series [w/video]

The biggest misconception about the Mercedes-Benz SLS AMG Black Series is that it's simply a higher-performing version of the SLS GT - a closer look, or better yet, a few hot laps on a high-speed racing circuit, reveals that is anything but the case.
Launched in the States in mid-2011, the standard SLS GT is a 583-horsepower, all-aluminum, gull-wing coupe with performance that positions it near the top of the exotic segment. While the AMG team at Mercedes-Benz could have left it alone, their experience with the SLS AMG GT3 race car said there was room for improvement, so they devised the SLS Black Series. The transformation from SLS GT to SLS Black Series is extensive, with no fewer than 17 different significant enhancements.
The engine mapping, crankshaft, connecting rods, valve-train, intake, exhaust and cooling are all modified and the engine's redline bumps up from 7,200 to 8,000 rpm, which pushes output of the hand-built 6.3-liter V8 to 622 horsepower. The power steering receives a new ratio, a coil-over AMG Adaptive Performance suspension is installed along with underbody braces, the track is widened, two-piece carbon-ceramic brakes replace iron rotors at each corner and a lightweight titanium exhaust is fitted beneath. The AMG Speedshift seven-speed dual-clutch gearbox is modified and an electronically controlled AMG rear differential lock ensures the power goes to the pavement. Last on the mechanical upgrades are new lightweight forged wheels (10x19 inches front and 12x20 inches rear) wrapped in special R-compound Michelin Pilot Sport Cup tires.

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.

Volvo S60 Polestar concept plays in the snow with Mercedes C63 AMG

Chris Harris took to a snowy stretch of tarmac to get a fingertips-on-the-wheel feel of the Volvo S60 Polestar concept. Harris says the turbocharged sedan with 508 horsepower and 424 pound-feet of torque - and a manual transmission - is "a study to see if Volvo can get back into the fast-car market." The Polestar S60 concept, one of which was already purchased for $300,000 by a private buyer, is still making the publicity rounds because even Volvo's Chinese owners realize that, as Harris says, "Volvo sold more cars because it made fast cars" like the old 850 T5 Wagon that stormed the British Touring Car Championship in the 1990s.
For reference, Harris compares the blue wonder to the Mercedes-Benz C63 AMG and its 487 hp and 442 lb-ft. The question is, were Volvo to get the price of a production version of the S60 Polestar to climb way down from its 200,000-pound sticker, could it be worthy competition to the established giants?
You can watch Harris divine the answer via a lot of drifting through the snow and a drag race in the video below.
