2014 Mercedes-Benz C63 AMG Edition 507 still lights our fire

The current Mercedes-Benz C63 AMG may be in the autumn of its years, but it's still one of our very favorite sport sedans. Ever. Yes, its paddle-shift transmission may not always follow orders, but with stupendous levels of thrust from its charismatic naturally aspirated 6.2-liter V8, ebullient rear-wheel-drive dynamics and that noise, we frankly don't care that it's getting on a bit.
As a sendoff of sorts for the current generation, Mercedes-Benz has just introduced a new Edition 507 model at the Geneva Motor Show, with 507 horsepower and 450 pound-feet of torque - an increase of 56 horses over the standard car. Mercedes credits the substitution of low-mass internals from the SLS AMG gullwing for the power bump, a tactic shared with the AMG Development Package upgrade that has been subsumed by this Edition 507. 0-60 is quoted at 4.1 seconds and top speed at 174 mph.
The Edition 507 borrows its aluminum hood from the C63 AMG Black Series Coupe, along with spidery new 19-inch wheels in either titanium gray finish or matte black with shiny rim flanges. As seen on our gallery car above, a sports striping package is also featured, as are glossy black grille, daytime running lamps, spoiler and mirror caps.

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 Concept GLA45 AMG is ready to run

This is the Mercedes-Benz Concept GLA45 AMG, and what we mean by that is, "This is the Mercedes-Benz GLA45 AMG." Mercedes has just unveiled the liveried 'concept' at the 2013 Los Angeles Auto Show, giving potential customers a very good look at the newest lunatic in the AMG asylum - a 355-horsepower, 332-pound-foot crossover that uses the same 2.0-liter, turbocharged four-cylinder engine found in the CLA45 AMG and Europe's A45 AMG.
Joined with a seven-speed, AMG Speedshift dual-clutch transmission and an AMG Performance 4Matic all-wheel-drive system, Mercedes promises a sub-five-second run to 60 miles per hour. That's not just quick for a crossover, that's quick full stop.
That sleek, lifted body has also been tweaked by the minds at AMG's Affalterbach facility. A new rear spoiler, side sills and front clip are the primary aerodynamic tweaks. Aesthetically, AMG has fitted the requisite "Turbo" badges, gloss-black accents (including exhaust tips and roof rails) and a set of 21-inch, AMG-spec alloy wheels to round out the overall package. Based on the spy shots we've seen, expect slightly toned down aerodynamics when the GLA45 AMG arrives in showrooms.
