Everybody's doing flying cars, so why aren't we soaring over traffic already?

"Where's my flying car?" has been the meme for impending technology that never materializes since before there were memes. And the trough of disillusionment for vehicles that can take to sky continues to nosedive, despite a nonstop fascination with flying cars and a recent rash of announcements about the technology, particularly from traditional automakers. Earlier this month, Toyota applied for an eye-popping patent for a flying car that has wheels with spring-loaded pop-out helicopter rotors. The patent filing says the wheels/rotors would be electrically powered, while in on-land mode the vehicle would have differential steering like tracked vehicles such as tanks and bulldozers. At an airshow in July, Aston Martin unveiled its Volante Vision Concept, an autonomous hybrid-electric vertical takeoff and landing (VTOL) vehicle it developed with Rolls-Royce. Aston says the Volante can fly at top speeds of around 200 mph and bills it as a luxury car for the skies. Audi used the Geneva Motor Show in March to unveil a flying car concept called the Pop.Up Next it developed with Airbus and Italdesign. If the Pop.Up Next, an electric and autonomous quadcopter/city car combo, gets stuck in traffic, an app can be used to summon an Airbus-developed drone to pick up the passenger compartment pod, leaving the chassis behind. Audi said that the Pop.Up Next is a "flexible on-demand concept that could open up mobility in the third dimension to people in cities." But Audi also acknowledged that at this point it has no plans to develop it. The cash-stoked, skies-the-limit Silicon Valley tech crowd is also bullish on flying cars. The startup Kitty Hawk that's backed by Google co-founder Larry Page announced in June that it's taking pre-orders for its single-seat electric Flyer that's powered by 10 propellers and is capable of vertical takeoffs and landings. The current version can only fly up to 20 mph and 10 feet in the air and has a flight time of just 12 to 20 minutes on a full charge. The Flyer is considered a recreational vehicle, so doesn't require a pilot's license. Uber says it plans to launch its more ambitious Elevate program and UberAIR service in 2023. "Uber customers will be able to push a button and get a flight on-demand with uberAIR in Dallas, Los Angeles and a third international market," Uber Elevate promises on its website.

Audi A3 G-Tron offers big range, few emissions

Audi is exploring a variety of sustainable transportation technologies beyond the traditional diesel, hybrid, plug-in and electric options, including the compressed natural gas A3 Sportback G-Tron that debuted today at the Geneva Motor Show.
The most interesting thing about this rather innocuous-looking A3 Sportback is that when run on Audi e-gas, the car becomes completely carbon neutral, emitting no more CO2 than was chemically input in this special fuel's production. Audi has already broken ground on a new plant - powered by renewable energy, of course - that uses electrolysis to produce e-gas, which could then be made available through any natural gas distribution network.

Next-gen Audi R8 E-Tron could have 280-mile range

Will the next hypermiling contest take place between the latest iteration of the Audi R8 E-Tron and a Tesla Model S. On paper, the single-charge range between the high- and higher-end EVs are nearly identical, so it's possible. But what fun would that be, using light pedal foot and all? Audi has released the latest specs for the R8 E-Tron, and they are just beastly. The EV will deliver 456 horsepower, have 679 pound-feet of torque and will be able to jet from 0 to 60 miles per hour in less than four seconds. More stunningly, the car will have a single-charge range of 280 miles, which is about 15 miles longer than the Model S's range. Audi says the new, long-distance pack is due to " new battery cells," but declined to go into detail. Despite the excellent numbers, not everyone thinks a new R8 E-Tron poses any threat to Tesla. Prices for the "base" version of the R8 with a gas-powered V10 engine start at 165,000 euros ($185,000), and there's no guessing yet what an EV version will cost. Whatever it is, the car's been markedly improved compared to the earlier iterations. We reported on progress of the new R8 E-Tron about a year ago that the single-charge range would climb to about 250 miles, and that the mill would deliver about 376 horsepower. Audi first showed off a concept version of the car at 2009's Frankfurt Auto Show, saying at the time that the model had a single-charge range of about 150 miles. So this is good progress. Check out Audi's rather lengthy press release below. Audi presents the new R8: The sporty spearhead just got even sharper The second generation of the high-performance sports car makes its debut in Geneva 5.2 FSI engine with up to 449 kW (610 hp), 0 to 100 km/h (62.1 mph) in 3.2 seconds New multimaterial Audi Space Frame with high proportions of aluminum and CFRP No model with the four rings is closer to motorsport, none is more striking and more dynamic: at the Geneva Motor Show, Audi is presenting the second generation of its high-performance R8 sports car. The V10 mid-engine and a newly developed quattro drive ensure breathtaking driving performance, especially in the top-of-the-range version with 449 kW (610 hp): achieving 0 to 100 km/h (62.1 mph) in just 3.2 seconds, its top speed is 330 km/h (205.1 mph).
