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.

Mercedes testing C-Class plug-in hybrid modes in Germany

Testing appears to be underway for what would be the first Mercedes-Benz C-Class with a hybrid powertrain. We can see a pair of the prototypes undergoing testing in Germany, with one, a C-Class Wagon, still heavily clad in camouflage and featuring a more noticeable outlet on the passenger side of its rear bumper.
There's also a more production-looking sedan, which features a not-so-discreet flap over its rear-bumper outlet. It's difficult to speculate on power outputs for this fuel-sipping C-Class, although our spies seem to think that this car will feature some combination of a four-cylinder gas engine with an electric motor, although just which four is unclear (note, we wouldn't mind if MB fit its 2.0-liter turbo with some batteries and motors). Regardless, the four-pot/electric motor seems like a pretty reasonable combo, although it probably means that Mercedes won't be challenging the six-cylinder-powered system of the BMW ActiveHybrid3 any time soon.
When the plug-in C-Class arrives later this year as a 2015 model, it will likely offer a full range of driving modes, including both gas or electric, only, as well as a more traditional hybrid mode.

How long will the 'golden age' of performance last?

High-powered sports and luxury cars were everywhere at the New York Auto Show, prompting the obvious question for enthusiasts: How long will this golden age of performance last? Industry leaders have some time before regulations elevate the Corporate Average Fuel Economy level in 2025. Even then, they expect cars rippling with power to survive in some form. "Is it the end of an era," I don't think so," said Ola Kallenius, Daimler AG board member for Mercedes-Benz cars marketing and sales. "That performance element of individual mobility I don't think will ever go away." Kallenius, who oversaw the company's AMG division from 2010-2013, expects it to continue to grow. Last year, AMG sold a record 68,875 units around the world, an increase of 44.6 percent over 2014, with strong growth in the US, China, and Germany. Still, there's always the potential for gas to spike, and pending fuel economy regulations are looming. That could lead AMG to add electrification to its products, Kallenius said, pointing to the electric SLS as a test case. Chevy is also thinking ahead, said Al Oppenheiser, chief engineer of the Camaro. He wouldn't bite when asked about electrification for the Camaro (he did say "never say never"), but admitted in 2025 "it's going to be pretty tough to sell V8s." For now, things are rosy for muscle cars, and Chevy confidently showcased the 640-hp Camaro ZL1 in coupe and convertible form in New York. "I think that this is truly the golden age of performance," Oppenheiser said. It's hard to disagree. News & Analysis News: The 2017 Mazda MX-5 Miata RF was a show-stopper in New York. Analysis: There was a palpable energy when this RF — for Retractable Fastback — was revealed the night before the show at a trendy off-site venue near the Hudson River. Even as a parade of SUVs and flashy luxury cars rolled out the rest of the week, the Miata remained a hot topic. The Retractable Fastback is really a clever targa top, with part of the roof stowing behind the seats, adding about 100 pounds compared to the standard convertible. It makes the car more practical and arguably more attractive. The RF continues Mazda's tradition of selling the Miata with a hardtop variant. The first and second generations offered a detachable one, and a power retractable hardtop (a $1,700 option) was available on third-gen models. Judging by its reception in New York, the RF could prove to be even more popular than its predecessors.
