Bentley must have really enjoyed issuing teasers of the Continental Supersports this winter, because it's doing it again this summer. The second partial image of the latest sedan from the U.K. company was released this week, along with word that the car will debut at the Pebble Beach Concours d'Elegance in August.

In honor of the company's 90th anniversary, Bentley will be the featured marque at the prestigious concours this year. The car will be revealed -- along with its name -- at the golf course where the event is held each year in Monterey, California.

As if Sir Stirling Moss tearing it up in a vintage racer all weekend weren't enough, there's the Sunday Times Supercar Run at the annual Goodwood Festival of Speed in the U.K. Some supercar manufacturers, like Pagani, bring new editions for a high-speed debut, while others, like Mercedes-Benz, bring whatever supercars they happen to have on hand. An SLR here, an SL65 Black Series there. You know how it is.

Here's a list of some of the supercars that took to the track at the 2009 Supercar Run over the Goodwood weekend, July 3-5:

• Aston Martin V12 Vantage
• Audi R8 V10
• Bugatti Veyron Pur Sang and Grand Sport
• Citroen GT concept
• Ferrari Scuderia Spider 16M
• Koenigsegg CCX-R
• Lotus Evora
• Mercedes-Benz SL65 AMG Black Series
• Mercedes-Benz McLaren SLR and SLR Roadster
• Mercedes-Benz McLaren SLR Stirling Moss
• Mercedes-Benz McLaren 722 and 722S
• Pagani Zonda R
• Porsche Panamera S

Aston Martin announced that it had a concept commuter car based on the teensy Toyota iQ. They call the concept the "Cygnet," which in case you don't know is a baby swan. The company seems to be acknowledging that this is an ugly duckling-type situation, with the other Astons in the barn serving as the graceful swans.

The Brits are collaborating with the Toyota team to come up with an ultra-luxury, environmentally conscious commuter car that could be sold along with the less-fuel-efficient DBS, DB9, and Vantage. Kind of like a prize in your cereal box.

Aston Matrin head Dr. Ulrich Bez said in a press release that "this project could become reality in the not too distant future." Stay tuned.

Longtime Lambo test driver Valentino Balboni is being honored for more than 40 years with the Sant'Agata supercar company with the limited-edition Lamborghini Gallardo 550-2 Valentino Balboni. Following the marque's recent naming convention, the 550 stands for horsepower, and the 2 for the number of wheels receiving power -- in this case, the rear two. Balboni was hired as a test driver in 1967 by Ferruccio Lamborghini, and his work testing Lamborghinis over the years influenced the final designs of cars from the curvy Miura of the Swinging Sixties to the hard-edged Gallardo and Murcielago of the New Millenium. The car named for the bull's favorite rider will be limited to 250 examples and set you back $219,800.

Brazilian-born artist Romero Britto has worked his pop-art magic on a Bentley Continental GT as part of his "Come to My World" exhibition in Berlin, July 10 through September 6. No photographs of the Continental-as-canvas were available, but the Bentley press release describes it thusly: "a large, happy flower, little stars, squiggles and signs dance on the elegant hood and colourful, comic-like figures adorn the doors." After the exhibit, the car will be auctioned off to benefit charity. Britto apparently has a bit of a history with Bentley, not all of it so flattering. In March 2009, the artist was arrested for driving drunk in his 2001 Bentley in Miami Beach. He also has a history of painting cars -- he did an Audi RS4 for Art Chicago in 2007.

The Citroen GT, previously seen on the small screen as part of the Gran Turismo 5 video game lineup, made its off-screen debut at the 2009 Geneva Motor Show. Now, Citroen says the supercar will take its next leap, from concept to production car. The UK magazine Autocar reports that Citroen plans on building a total of six GTs, at a cool $1.8 million apiece. Several major aspects of the concept will be kept for the real-world car, like the mid-engine layout and carbon fiber body, but the powerplant will have to change. The concept had a series of electric motors that added up to more than 700 hp; the production version will likely use a gasoline engine from Ford or GM and top 500 hp. No word yet on when the Citroen GT might be ready for delivery, so you've got some time to save up your pennies. All 18,000,000 of them. You're going to need a bigger change jar.

The "Volante" in the 2009 Aston Martin DB9 Volante means "convertible." And what better way to spend a sunny summer weekend than test driving a top-down 12-cylinder? Check out the image gallery for pictures of the DB9 Volante -- top up, top down, inside and out.

I had a 2009 BMW 750i to test drive this past weekend, and it was absolutely lovely -- except, of course, for the cracked rim I suffered on the first day. Read all about it in the review, plus the much improved iDrive system, the smooth ride, and the six-figure price tag. Also, I took some pictures of my Titanium Silver Metallic tester with black nappa leather interior. Slick as city streets in a thunderstorm -- another area where the 750i performed well for me.

The Straightline blog at Edmunds.com has confirmed that the new, and as-yet-unrevealed, Audi R8 convertible will be featured in the next Iron Man movie. If you'll recall, Tony Stark (played by Robert Downey, Jr.) drove a silver hardtop R8 in the first Iron Man flick, an adaptation of a Marvel comic.

Straightline also has images of the car taken by crafty car spies at the Nurburgring in Germany. Apparently, in order to make the soft top work, the distinctive carbon or silver strips behind the doors have been deleted. I like the look of those intake covers, but others find them distracting.

What do you think? Is an Audi R8 without its carbon-fiber intake covers a little less special, or a little more refined? Does it matter when you've got a 0-60 time likely under 5 seconds and a clear view of the sky above? Leave your opinions in the comments.

Chrysler reported that it only had one, low, lonely offer for its Dodge Viper business prior to being brought under Fiat's umbrella earlier this month. Since they didn't accept the offer, the Viper went along for the ride and is currently part of Fiat's assets.

Immediately post-sale, the first factory Chrysler fired up was the one that builds Vipers. The plant only has a little over 100 employees, though, so it was probably the easiest one to restart. But according to an article in the Wall Street Journal, the Viper is still headed for the chopping block by the end of the year. If you've got $100,000 or so and a need for 600 hp from 10 American-made cylinders, better get it while the gettin's good.
