Artist imagines eerie world where cars have no wheels

The wheel ranks right up there with the telescope and four-slice toaster in the pantheon of inventions that have moved humankind forward. But what if a circle in three dimensions had never occurred to anyone, and we all had just moved on without it? Perhaps we'd be driving around in Lucas Motors Landspeeders with anti-gravity engines. Or maybe we'd have the same cars we do today, just without wheels.
That's the thought experiment that seems to have led French photographer Renaud Marion to create his six-image series called Air Drive. The shots depict cars throughout many eras of motoring that look normal except for one thing: they have no wheels. The models used include a Jaguar XK120, Cadillac DeVille (shown above), Chevrolet El Camino and Camaro, and Mercedes-Benz SL and 300 roadsters.
Perhaps one day when our future becomes our past, you'll be able to walk the street and see with your own eyes the rust and patina of age on our nation's fleet of floating cars. Until then, Monsieur Marion's photographs will have to do.

How GM's grueling 24-hour test gets the kinks out of its performance cars

One of the biggest challenges automakers face when designing a high-performance car is making sure that it is both fast and reliable. For General Motors, any car that might be taken to the track by its owner - like the Corvette, Camaro Z/28 (shown above) and the Cadillac CTS-V, for example - undergoes a rigorous and strenuous 24-hour test by engineers at the Milford Proving Grounds, as pointed out by Car and Driver.
We've posted on this topic in the past - on a video showing the Camaro ZL1 being brutalized, for instance - but this article gives a more in-depth look at what actually happens behind the scenes... including what that poor ZL1 went through. Though the test isn't for 24 hours straight, the cars are pushed as hard as possible by some of GM's best drivers with only the brakes and tires replaced frequently.
We don't want to ruin the fun for you, but it is an interesting article that tells just some of what GM does to develop its sports cars. Check out the full article over at Car and Driver for the rest of the story.

Cadillac bids farewell to CTS-V Coupe with special edition

With the introduction of the latest Cadillac CTS, we knew it would only be a matter of time before a new CTS-V would come along. Now General Motors has revealed that the next CTS-V will arrive sometime next year, but before it does, the company is sending off the outgoing coupe with a special edition.
For 2015, the Cadillac CTS-V Coupe will come in a limited edition of 500 units decked out with a dark grille treatment, satin-finish wheels, red brake calipers and an upgraded cabin. The interior is decked out Recaro seats trimmed in black with red stitching, Midnight Sapele wood trim, metal pedals and a microsuede-trimmed steering wheel and shifter.
Buyers will be able to opt for white, gray or optional black exterior paint, an available sunroof and a six-speed transmission in either manual or automatic configuration. Of course, the 6.2-liter supercharged V8 comes standard with 556 horsepower, as does Magnetic Ride Control and brakes by Brembo. Pricing will be announced closer to launch, but in the mean time, you can read all there is to know by checking out the official release below.
