Aston Martin signs Letter of Intent for technical partnership with AMG

A little over two months ago came reports that Daimler and Aston Martin were in talks, again, about "supply and technical-cooperation agreements." The next step has been taken with Aston Martin announcing that it has signed a Letter of Intent that looks "towards a technical partnership" with Mercedes-AMG GmbH, and the two companies aiming to have definitive agreements done by year's end.
While it will get to use certain electric and electronic components from AMG, the true golden egg for the maker of the Vanquish will be the ability to develop a new line of "bespoke V8 powertrains" that will be fitted to "a new generation of models." In return for opening up the larder, Daimler will get a non-voting stake of up to five percent of Aston Martin.
Nothing else is being said about the tie-up for the moment, but there's a press release below with a few more details.

Singer Porsche, Koenigsegg, NSX: Leno's life doesn't suck

Jay Leno had quite a productive trip this year during Monterey Car Week. Not only did he get to pal around with Ian Callum and check out the Pebble Beach Concours d'Elegance, but the denim-clad comedian also headed to The Quail to talk to some prominent figures in the modern sports car scene. Capping off the fun, he got to take a drive in a Mercedes-AMG GT S, too Perhaps the highlight of this show is a nearly 10-minute interview with Christian von Koenigsegg. The founder of the Swedish hypercar company digs deep into the Agera One:1's engineering details, relating interesting facts about the aerodynamics and transmission. In addition, Leno chats with Rob Dickenson of Singer about its newly reimagined Porsche 911 Targa, and he gets the latest scoop on the Acura NSX's progress from newly promoted Acura Vice President and General Manager Jon Ikeda. If you like hearing about the nuts and bolts of sports car development, then this video can't be missed. Of course, we were there at Monterey, too, and we pointed our own cameras at some of the amazing machinery, both vintage and modern, at all the various car-focused events of the week. Take a look back at some of our own cool footage in the videos below. Related Video:

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.
