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.

Highlights from the Goodwood Festival of Speed, including the McLaren P1 and a Ford Transit running the hill

The sole purpose of this post is as a time-waster, and since you shouldn't have to work to waste time, we've done it for you. In the numerous videos below you'll find cars that have lately been in the news tramping all over the grounds of Lord March's estate in Goodwood, England.
There's the McLaren P1 heading up the hill, the Jaguar Project 7, then a casually-driven Porsche 917 followed by an even-more-casually-driven Porsche 956, topped off by a Porsche 936 that is anything but casually driven. The next round is the flame-spitting Peugeot 405 T16 Pikes Peak from Climb Dance, a camera mounted on the Peugeot RCZ R after it showing you what the whole, uninterrupted run up the hill looks like. For a real head-turner, we couldn't embed it but there's Andy Reid blasting up the hill in a Ford Transit Supervan with a Cosworth 3000 V6 engine.
The modern racing contingent has Allan McNish doing the hill in the Audi R18 e-tron quattro he used to win Le Mans and Lewis Hamilton making lots of tire smoke in the Mercedes-AMG Petronas MGP-W02. For comparison, that's followed by Nick Heidfeld's record-setting run up the hill in 1999 in the McLaren MP4/14 . The classic racing contingent is headlined by 71-year-old Giacomo Agostini on an MV Agusta.

Mercedes-AMG considering turbo fours, hybrid sixes for future performance sedans

Think of the letters AMG and you'll probably end up picturing a performance sedan with a big V8. Such has become, after all, the Mercedes turning division's calling card. But with the introduction of its 2.0-liter turbo four, AMG is working at turning that notion on its head.
The highly potent engine produces 355 horsepower and is presently installed in the A45 AMG hatchback, CLA45 AMG sedan and GLA45 AMG crossover, giving Benz's smallest family a full range of performance models. But that might not be the full extent of the high-strung four-pot's use.
Speaking with AMG boss Tobias Moers, Britain's What Car? magazine reports that Affalterbach is considering slotting the same engine into larger models, particularly performance sedans like the C-Class. As we recently reported, Mercedes is already preparing to up the power from the turbo V6 in the C400 to slot a C450 Sport in below the C63 AMG. The C450 is expected to offer around 367 horsepower where the CLA45 AMG et al pack 355, but the lighter weight of the four-cylinder engine would likely offset the truancy of those extra dozen horses. Of course such a prospect would be much further down the pipeline than the C450 Sport which is expected to arrive much sooner.
