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

Now Even Sharper Than The Razor's Edge
There have been five Black Series models since the Mercedes-Benz SLK55 AMG Black Series introduced itself to European audiences in 2006. Following that, the Black Series club has hosted appearances by the 2008 CLK63 AMG Black Series, the 2009 SL65 AMG Black Series and last year's 2013 C63 AMG Black Series. The sixth member of the group is one we would have thought already was a Black Series car in its standard guise. Right out of the box, the SLS AMG is loud, frenetic, cozy, boisterous and frightfully easy to oversteer. How much more Black did it need to get?
Quite a bit so, apparently. The SLS AMG Black Series has lost weight, gained power and been refitted with upgrades and aero bits from front to rear. If you liked the way it looked before, you'll probably be an even bigger fan of this one. If you thought it looked ungainly, well, this one should stay even further away from pageants. Regardless of where you come down this is the best SLS AMG variant we've driven.

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.

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.
