Aston Martin and Mercedes-AMG formalize technical partnership

The development of a partnership between Mercedes-Benz and Aston Martin has been a long time coming. The news dates back to 2008, and over the five years since was supposed to lead to a rejuvenation of both the Maybach and Lagonda brands. That program ultimately fell apart, but the tie-in was forged afresh in July when the two automakers signed a letter of intent over a renewed partnership. And now that partnership has been formalized.
In a deal just announced, Mercedes-AMG will build a new V8 engine for Aston Martin that will power a new generation of luxury GTs for the British marque, presumably to replace the 4.7-liter V8 in the Vantage. The relationship appears to be similar to the one already in place between AMG and Pagani, only in this case, will involve Daimler taking as much as a five-percent stake in Aston Martin and an observer seat on Aston's board.
The technical partnership is also set to lead to the supply of electric and electronic systems, and could incorporate "additional areas of cooperation in the future." Whether that will include a fresh attempt at reviving Lagonda remains to be seen, as does the future of Aston's long-serving, Ford-based 6.0-liter V12 engine. But for now you can read the full announcement below.

Brabus to storm Geneva with 800-hp version of Mercedes SL65 AMG

At no point during our recent drive of the 2013 Mercedes-Benz SL65 AMG did we ever think, "You know, this thing sure is slow." After all, Merc's range-topping SL comes fitted with a twin-turbocharged 6.0-liter V12 capable of sending 621 horsepower and 738 pound-feet of torque to the rear wheels. But just in case you're still all "meh" about what the SL65 throws down, Brabus will gladly come to your rescue with this, the 800 Roadster.
As its name suggests, the 800 Roadster ups the V12's power figures to 800 horsepower and - wait for it - 1,047 pound-feet of torque. Don't get too excited, though - that torque number has been electronically limited to a measly 811 lb-ft since, you know, the transmission would probably explode if you tried to put the full force through it. Nevertheless, these represent increases of 79 hp and 73 lb-ft over the standard SL65, and that means the 800 Roadster can shoot to 62 miles per hour in just 3.7 seconds - two-tenths of a second quicker than the Merc its based on. More impressively, hitting 124 mph takes just under 10 seconds, and the droptop will finally top out at an electronically limited - limited! - 217 mph. Holy smokes.
To manage all of that speed, Brabus has engineered a special carbon fiber aero kit that reduces lift, and a unique control module for the SL65's active body control suspension lowers the ride height by one full inch. The 800 Roadster rides on new 20-inch wheels, and a unique limited-slip rear differential was added, featuring a 40 percent locking rate that further enhances performance when you're attempting to control the beast at its limits. Interior upgrades include new leather and alcantara surfaces throughout the cabin, including a leather-clad trunk.

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.
