There’s hope yet for the flying car. Really. The Jetsons-era dream of personal air vehicles (PAVs) has recently received a few gasps of fresh air (click here for an update from Resident Roboticist Daniel H. Wilson). An advocacy group, the CAFE Foundation, has launched a $250,000 PAV challenge for new and interesting flight concepts. Plus, companies from the aviation (Boeing) and automotive (Honda) industries are pursuing mainstream airborne-vehicle technology, though no designs or deadlines have been announced. In the meantime, several independent companies have been researching and developing fly/drive vehicles you might see flying – someday – toward a driveway near you.>MollerSkycar M400 “>With production versions promised by 2010, this four-passenger beauty is the latest in a line of Moller Skycars dating back to 1962. Using four pairs of Wankel engines, the vehicle is designed for vertical takeoff and landing, and may eventually be capable of fully automated flight.RANGE 750 miles ALTITUDE Below 36,000 feet TOP AIRSPEED 375 mph PRICE$995,000 A $100,000 deposit holds one of the first 100 cars, refundable if FAA certification does not occur by Dec. 31, 2010. PROGRESS Tethered full-scale prototypes have hovered several feet off the ground. POTENTIAL DRAWBACKS Frequent delays and misleading claims led to an SEC fine in 2003.>Labiche AerospaceFlying Sports Car FSC-1Media Platforms Design TeamThe four-passenger FSC-1 has been in development since the late 1980s, and reached preproduction in 2007. Like a Transformer toy, the FSC-1 turns from car to single-propeller airplane in 30 seconds. A true hybrid, it will operate via existing small airports and highways.RANGE 950 miles ALTITUDE Below 34,000 feet TOP AIRSPEED 275 mph PRICE$175,000 The FSC-1 is a kit, assembly required. The $20,000 deposit is refundable if performance benchmarks aren’t met. PROGRESS A prototype will be on display in Los Angeles this year; production is slated for 2008. POTENTIAL DRAWBACKS Plans to fly it to the 2007 Oshkosh air show were scrapped due to testing “conflicts.">Urban AeronauticsX-HawkMedia Platforms Design TeamConceived by a former Boeing engineer in 2001, the 11-seater X-Hawk is marketed as, among other things, an emergency vehicle (to go where choppers can’t). It uses enclosed turbine-powered, ducted fans for lift and a system of vanes for stability and maneuvering. RANGE 380 miles ALTITUDE Below 12,000 feet TOP AIRSPEED 161 mph PRICE$5 million to $6 million The X-Hawk’s price reflects its proposed emphasis: fewer civilian thrill rides, more military or medical response. PROGRESS Exists largely as a set of plastic moldings and a virtual computer simulation. POTENTIAL DRAWBACKS Based on 1960s “Air Jeep” technology, which has yet to prove itself in 50 years.
