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.

Chris Harris and David Coulthard wring out a Mercedes Fintail at the N"urburgring

If there's one thing we've learned from the latest video from Drive, it's that the combination of Chris Harris and David Coulthard will produce some very quotable moments. Take this exchange, for example.
DC: "We are by some way the slowest."
CH: "But we're in a class of three cars, apparently."

Is Audi getting complacent and suffering from brain drain?

The argument is made in a Reuters article: Audi is falling behind other luxury brands, such as Mercedes-Benz and BMW, due to a lack of research-and-development spending and "brain drain," or the migration of top executives and R&D chiefs to other parts of the Volkswagen Group. Reuters notes that Audi's current R&D chief is the third in 16 months.
Audi, which contributed to 40 percent of VW Group's $11.6 billion in profit the first nine months of the year, is delivering cars at a record pace: 1.31 million were delivered from January to October 2013 versus BMW's 1.35 million. Yet Audi, Reuters reports, doesn't have a halo car akin to BMW's new electrified i3 and i8 or an answer to Mercedes' plug-in-hybrid S-Class, and the R&D spending at Audi is less than BMW and Mercedes by a fair margin. It's noted in the article, however, that Audi benefits from other R&D spending within VW Group.
Reuters mentions that BMW "trumpets its new 'i' series" and the new Mercedes CLA and GLA ranges are winning "rave reviews" as part of its argument that Audi's recent lack of technological innovation could hurt future sales. Those cars do pack tons of new technology, some of which are firsts for mainstream production cars. But last time we checked, the i3 could be causing BMW's stock to slide, the CLA isn't receiving the rave reviews that Reuters would have you believe and the GLA hasn't been reviewed yet.
