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.

XCAR marks 20-year anniversary of Senna's passing with Mercedes 190E Cosworth

While the automotive world is focusing on the twentieth anniversary of Ayrton Senna's death, there was much, much more to the legendary driver than his untimely passing at the 1994 San Marino Grand Prix.
XCAR has the story of a younger Senna, who, by a stroke of luck, found himself matched up against a veritable dream team of nine Formula One champions, not to mention a cadre of German touring car aces. A "probably still pissed (drunk)" James Hunt, hard-driving Niki Lauda and future champion and rival Alain Prost, were in attendance for the one-off, spec race, which was put on by Mercedes-Benz, in honor of the opening of the Nürburgring's Grand Prix circuit. And Senna was on hand with the explicit goal of besting them all.
Each driver was handed a lightly modified, but brand-new 190E 2.3-16 Cosworth, a car that can best be though of as the distant ancestor of the lovable C63 AMG. As for the race itself, well, it was sort of like an introduction of what the sport could come to expect from the Brazilian.

Brabus 800 Roadster is a power-mad aristocrat

If we're being completely honest, we haven't exactly been in love with the aesthetics of the sixth-generation Mercedes-Benz SL-Class. It's mostly a front-end issue, with its glowering eagle-eye headlamps and upright, dinner-plate-sized Three-Pointed Star coming across to us as overwrought. That's particularly troublesome for a roadster whose history has of the most elegant designs of all time in its back catalog. Somehow, the new R231 generation's brash visuals seem more at home on this Brabus 800 Roadster to us.
That's probably because the high-dollar German tuner has turned up the wick on the SL's visuals even further, with carbon fiber bodywork, a more aggressive aero kit, matte hood scoop and complex two-finish wheels. It's all-the-way committed to its brashness, in other words - and justifiably so. Anything with 800 horsepower and 1,047 pound-feet of torque has earned the right to look however it wants, right?
Brabus started with the SL65 and its not-exactly-underpowered 6.0-liter twin-turbo V12, and went to town, fitting their own turbocharger and intercooler system, along with a less-restrictive exhaust system with driver-selectable sound levels and new engine electronics. The result is a 3.7-second 0-62 mph time, an electronically limited top whack of 217 mph... and one seriously compromised toupée.
