Volvo specs new 450-hp triple-charged four-cylinder engine

When Volvo lifted the veil on the new XC90 a little over a month ago, it announced that all versions would be powered by one engine design: a new 2.0-liter four-cylinder to be offered in various states of tune. That would range, Volvo said, all the way up to a high-output version with "around 400 horsepower," but while it wouldn't specify exact output, now it has.
The new High Performance Drive-E Powertrain incorporates two parallel turbochargers fed by a third electric turbo-compressor. Instead of feeding the cylinders directly, that third unit spools up the twin turbochargers, working together with a dual fuel pump pressurized to 250 bar.
The result is an output of 450 horsepower - far more than the existing 320-hp version and even more than expected. That also works out to 225 hp/liter, far more than the 177 hp/liter boasted by Mercedes-AMG's high-output turbo four and the 139 hp/liter in the Alfa Romeo 4C. Short of a rotary engine (whose actual displacement is the subject of great debate), you'd have to go up to something like the Koenigsegg One:1 (268 hp/liter) to find a higher specific output than what Volvo's boasting here.

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.

Recharge Wrap-up: Formula E car swap video, Lyft adds carpooling, new Tesla book

Curious to see how the Formula E car swap goes down? During each hour-long race (or ePrix, as the series calls them), drivers have to make a pit stop to switch cars as the battery runs down. Of course, they want to do it as quickly as possible. It's kind of a tricky dance extricating oneself from the cockpit of one car and slipping into the seat of another facing the opposite direction. See the maneuver in the video below and read more at Jalopnik. A new report forecasts that the CNG and LPG vehicle market will be worth nearly $5.2 billion by 2019. The report cites fluctuating gasoline and diesel prices, and the relatively low prices of these alternative fuels, for their growing popularity. The report also breaks down the popularity of natural gas and propane vehicles in different parts up the world. In the Asia-Pacific region, China is the largest consumer. In Europe, CNG thrives in Italy, while LPG is most popular in Turkey and Poland. Meanwhile, CNG remains a tough sell in America, while South America has a healthy market.

The Ports of Los Angeles and Long Beach are testing trucks connected to overhead electric wires to reduce emissions and improve air quality. The eHighway, as the project is called, will cost $13.5 million and will use battery electric and hybrid trucks to move cargo around the ports along a one-mile stretch of wires. The trucks, made by Siemens and Volvo, also have the ability to disconnect from the wires and drive under their own power. See more in the video below or read more at ABC7. Lyft is introducing its own carpooling feature to its car-hailing app. Yesterday, we reported that its competitor Uber is testing UberPool, and Lyft is now doing something similar to encourage people to share rides. Lyft Line offers discounted rides, and matches passengers who are going to nearby destinations around the same time. Lyft Line offers passengers a guaranteed price before they accept the ride. Lyft is launching the carpooling service in San Francisco, and hopes to expand it from there. Read the in-depth article at The New York Times. A new book is available called Tesla Motors: How Elon Musk and Company Made Electric Cars Cool, and Sparked the Next Tech Revolution. Written by Charles Morris, senior editor of Charged, it chronicles the history of the famed electric automaker, its achievements in business and technology and the people responsible for Tesla's success.
