Move over hybrids -- the Transition is here. Half car, half plane, this "roadable aircraft" is 19 feet long and 6 feet 9 inches high, with an expandable wingspan of 27 feet. It runs on regular unleaded gas for both on-ground and in-air travel, cruising at highway speeds on land and upwards of 115 miles per hour in the air. The two-seater car-slash-plane had its maiden voyage March 5 at the Plattsburgh International Airport in New York, with a retired US Air Force Reserve colonel in the pilot's seat.

The auto industry is getting a nice punch in the nads with recent slowdowns in car rentals. The current economy doesn't really make people feel like traveling so much, so sales to rental cars fleets are in steep decline. This dropoff is then passed directly to automakers because the rental car companies are not restocking their lots as much. "Fleet sales" -- large-scale sales from the automakers to rental car companies -- are no longer so popular, and they're cutting into what used to be a reliable 20% of all sales for companies like Chrysler, General Motors, and Ford.

President-elect Barack Obama's 2005 Chrysler silver-blue 300c is back on eBay and can be yours for a mere million dollars. According to the website hyping the auction, the opening eBay bid starts at $100,000 with a "buy it now" price of $1,000,000. The 300c is loaded with leather, sunroof, navigation, chrome wheels, a HEMI, and with only 20,801 miles, it's still under warranty.

Paul Newman took his final laps at Lime Rock racetrack just weeks before he died. It was his home track. Like Newman, the 1.5-mile track is a little rough around the edges but has tons of charm. And with "blind crests and fast corners," it's a lot of fun to drive -- especially for those wanting top out at 185 mph. Located in Lakeville, Connecticut -- a snappy two hours from Manhattan -- the track is tucked in the foothills of the Berkshire Mountains and has been hosting racing since 1957, most notably the Grand-Am GT Classic and the Le Mans Series.

It doesn’t take a kilo of coke in your trunk to be caught ridin’ dirty. Car emissions kill 30,000 Americans each year. Carbon monoxide, nitrogen dioxide and formaldehyde are just a few of the poisons released every time drivers peddle the metal. But, fear not (too much). Bosch, the world’s largest automotive supplier, has unveiled Clean Diesel engines that run on fuel so pristine, each one reduces greenhouse gas emissions by 25 percent. A 30 percent better fuel economy means less refills (luckily, since only 42 percent of stations are equipped with the fuel). The initial fleet of Clean Diesel cars includes models from Audi, BMW, Mercedes-Benz and Volkswagen. Bosch claims the exhaust fumes are even cleaner than the air out there, but don’t take their word for it -- unless you’re in Los Angeles.

Singapore is hosting the first-ever Formula 1 night race, and the 3.15-mile Grand Prix is a crash course in Singapore architecture. The Singapore River and the Singapore Flyer (like the London Eye on steroids) will serve as the blurry landscape zipping past the million-dollar racing machines. The whole Speed Raceresque shebang -- track, cars and landscape -- will take place under 2,000-watt floodlamps, making the whole “night” part of the race a metaphor at best. Play along for a chance to see the action in real time by racing virtual cars on the Singapore Racer site. The virtual winner will be gifted an all-expense-paid trip to the Singapore Grand Prix on September 28. In case you don’t win, book a package to make the race.

Here’s Ian Cook, a British artist who paints pictures by dipping the wheels of a remote controlled car in paint, then driving it all over the canvas. Inspired or gimmicky? I can’t decide.

Here's a wonderful thing you can't have! (Yet.) Only 40 of these custom-leather iPhone pouches were handed out as comp gifts during Berlin's fashion week by Mercedes-Benz, celebrating the launch of their GLK-Class line of wunderbar autos. The glittery "GLK" logo is made of Swarovski crystals that actually transmit the comforting glow of your iPhone's display when safely pouched. If you want a black variation, you'll have to wait till October.

If Indian car manufacturer Tata Motors designs a super-small car on the cheap and calls it the Nano, can Apple sue? We'll find out soon enough. According to the website, the car's name denotes "high technology and small size," the same reasons we're guessing Team Jobs christened their pint-sized iPod the exact same thing, several years before. The Tata Nano is dubbed "The People's Car," probably because it'll sell for $2,500 a pop, making it the cheapest car (relatively speaking) ever sold. Since "Mini" is already taken, and since the word "Nano" already denotes a tiny iPod, perhaps Tata should've gone with "Micro," or better yet, the "Zune."

Versace seems to own Milan this year. First politics, now cars. But not just any car -- Lamborghinis. The fashion house is teaming up with venerable automakers to roll out the new Murciélago LP 640 Roadster, which promises to be a truly stylish ride. During Fashion Week in Milan, the Italian rapscallions agreed to design the interior of a limited-edition Lamborghini car and its accompanying accessories like gloves, bags, suitcases, and trolleys in the latest collaboration between the two luxe brands. Accessories go on sale in November.
