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:

Aston Martin tipped for F1 return with Red Bull, Mercedes

Aston Martin could be plotting a return to Formula One for the first time in over half a century. And not as a backmarker, either. That is, at least, if the latest rumors materialize. While most automakers that participate in F1 do so as either a team owner (like Ferrari and Mercedes) or as an engine supplier (think Renault or Honda), the rumored Aston Martin deal would take a different approach. According to Autosport, the proposal would have the Red Bull Racing team run Aston Martin branding – but not its engines. Those would be provided by Mercedes, just like the engines in the British marque's upcoming slate of road cars. In that regard, the deal would not be unlike the one which Red Bull currently has with the Renault-Nissan Alliance, which sees the team running Renault engines and Infiniti branding. Andy Palmer was a pivotal figure in brokering that unusual arrangement when he was working for Carlos Ghosn, and is now tipped to be brokering a similar deal in his new capacity as Aston Martin's CEO. Though Aston has found glory in sports car racing (including Le Mans and its various associated series), it was never much of a contender in grand prix racing. It competed in a handful of races in 1959 and 1960, but never achieved results worth bragging about. Aston was rumored to be plotting a return when David Richards sat as chairman of the company, having run Aston's racing program as well as Honda's F1 team previously. Those rumors, however, never materialized. Whether this time 'round gains any traction remains to be seen - Aston Martin declined to either confirm or deny the reports when reached for comment by Autoblog. Red Bull has been growing increasingly dissatisfied (and increasingly vocal about its dissatisfaction) with Renault engines over the past couple of seasons. Though the two parties won four back-to-back world titles together, things took a noticeable step backward after the new turbo engine regulations took hold for the 2014 season. Nissan/Infiniti and Red Bull are contracted to continue collaborating until the end of next season. After that is when the new Aston deal could take hold, and Mercedes is reportedly keen on the idea so that it could add another customer to its F1 engine supply business and offset the costs of development. That could effectively prove the end of Renault in F1 (at least for the time being). Aside from Red Bull, the French automaker currently supplies only that outfit's sister team Toro Rosso.

New Mercedes Unimog debuts to the cheers of little boys everywhere [w/video]

The Mercedes Unimog, the superhero villain of the off-road world that's just waiting to make the jump to Transformer, has been completely upgraded for its new generation. There are ten models, expanding the range and getting new designations across the traditional all-terrain series and the implement-carrier series. Panoramic cabins get more visibility, multifunction steering wheels and better dash clusters, improved HVAC and a three-mode central tire inflation system. Outside, there are new items like LED headlights and daytime running lamps in the bumper, roof-mounted windshield wipers and a front-camera monitor for the implement carrier.
The new engine lineup is compliant with Euro VI, featuring four- and six-cylinder BlueEfficiency engines putting out anywhere from 156 horsepower to 354 hp. Powerplant placement has also been tweaked, the chassis members getting a revised curve to place the engine a bit further back and lower, maintaining off-road clearance and lowering the Unimog's center of gravity. The new location of the engine means the cabin has more room, and the wheelbase is shorter. Combined with a higher turning angle, the Unimog has a smaller turning radius than before.
The implement carrier gets what's called a "synergistic traveling drive," the bonus being that drivers don't need to stop in order to use an attachment - a hydrostatic transmission works with the regular manual transmission at up to 31 kilometers per hour for seamless switching.
