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:

Watch the incredibly complicated operation of Porsche's new targa roof

Despite Porsche having claimed the name, targa tops are nothing new. In addition to the semi-roofless version of the 911, plenty of cars in the past have used removable roof panels - the new Corvette Stingray has one (as have prior generations), and this type of open-air experience has been available on past vehicles like the Pontiac Solstice Coupe and Honda Civic del Sol.
But when Porsche took the top off its brand new 911 Targa here at the Detroit Auto Show, it was indeed cause for pause. Simply put, this is one of the most complicated and intricate electronic roof panel removal techniques we've ever seen, save perhaps, for the setup found on the Japanese-market Civic del Sol from the 1990s.
We won't spoil the video for you, but basically, rather than just the roof panel coming off, the entire rear glass area lifts away the body in order for the small section over the passenger compartment to slide back. This has to be incredibly expensive to repair once it inevitably breaks. And we highly doubt you'll be able to operate this mechanism at any speed.

Porsche Cayman S and Caterham 7 go head to head on the drag strip

We recently saw the standard Porsche Cayman go up against a Subaru WRX STI in a one-mile drag race with surprising results. Apparently, Evo had a similar idea of evaluating the Cayman's quickness. However, it opted for the more powerful S model and chose a flyweight Caterham Roadsport 140 as the challenger. Will the results of this battle be as close at the end of the kilometer-long (0.62-mile) drag?
Neither of these are cars you'd usually associate with drag racing, but they are nearly evenly matched. Evo selected them based on power-to-weight ratio, with the Caterham offering a scant 140 horsepower in a lithe 1,213-pound package. The Porsche is a quite svelte 2,910 pounds but has 325 hp to haul it around.
Of course, power-to-weight ratio isn't everything. There are a ton of other variables like aerodynamics and gearing that play a huge role, as well. Can the little Caterham's weight advantage overcome the better aero and additional power of the Porsche? Scroll down watch the video and find out.
