Recharge Wrap-up: NASA's EV plane, GM and Navy partner on fuel cell drone sub

NASA is building an all-electric test aircraft called the X-57. The lightweight plane's design balances speed with efficiency. The wings house two main propellers at their tips, with twelve smaller motors with retractable prop blades dotting the wing's lead edge. This helps it get the lift it needs to take off while reducing drag in the air, a delicate balance rooted in wing design. The X-57 is part of NASA's 10-year New Aviation Horizons program to make aircraft quieter, more efficient, and less polluting. Fans of The Right Stuff are sure to be pleased to see X-designated planes back in action. Read more at Wired. Suzuki has made its Baleno hatchback more efficient with a mild hybrid system. The European model has a lithium-ion battery pack under the front passenger seat that stores energy from a regenerative braking system to supplement power from the 1.2-liter engine during acceleration. Suzuki says the system improves the Baleno's fuel economy and reduces CO2 emissions by about five percent. Read more from Automotive News Europe. The Borgward BX7 plug-in hybrid SUV has won several Plus X Awards. The revived German automaker's PHEV received awards in the categories of Design, High Quality, Ergonomics, and Functionality. Any Plus X Award winner must display added value, which the panel of judges call the "Plus X Factor." The BX7 launched in China earlier this year, with plans to go on sale in India later this year and Europe soon after that. Read more at Green Car Congress. General Motors and the US Navy are teaming up to power underwater drones with hydrogen fuel cells. The Navy's goal is to provide its large displacement unmanned undersea vehicles (UUVs) with 60 days of operation between refueling. "Our in-water experiments with an integrated prototype show that fuel cells can be game changers for autonomous underwater systems," says Frank Herr, head of Ocean Battlespace Sensing at the Office of Naval Research. "Reliability, high energy, and cost effectiveness – all brought to us via GM's partnering – are particularly important as Navy looks to use UUVs as force multipliers." GM says that just as on-road experience gained through its Project Driveway fuel cell test fleet is valuable, automotive customers stand to benefit from lessons learned from this naval project.

Man chases down truck thief and steams it all on Facebook

A Washington man chased down a truck stolen from his family's dealership last Saturday and livestreamed the event on Facebook. According to KOMO, a 2005 Ford F-250 was stolen from Sunrise Auto Sales in Eatonville, Washington on the morning of October 8. Aaron Babcock, who co-owns the small dealership with his father David, told reporters that after reviewing surveillance footage, he later spotted the truck while riding his motorcycle on Webster Road East. "I watched my cameras and found the video of a man lurking around and ending up taking off with my truck," Babcock told KOMO. "Cops came and made a case. Three hours later I was on my motorcycle in Graham, and they drove by me oncoming. It still had dealer stickers on it. It said diesel on the window and it had our dealer plate on it. It stuck out like a sore thumb. It was really easy to see." Once he spotted the stolen Super Duty, he wheeled his bike around and gave chase. He attempted to call 911, but was unsure if the dispatcher heard him due to noise from the wind and the bike's engine. So he fired up Facebook live and started streaming his chase, giving running commentary and updating his location as he chased the slow-moving truck. "I wasn't going to let him get away. I was going to try follow him down. I had no idea what to do," Babcock said. "Nobody could hear me on the phone so I just figured the first thing to do is pull up Facebook live." Babcock's Facebook friends pitched in by calling 911 to report the chase and even jumping in their own cars to follow the truck. At one point, he pulled alongside the truck and recognized both men in the cab. The driver was the man seen lurking around the dealer lot in the surveillance video, and the passenger was an old friend of Babcock's. "I know who you are!" he shouted at them, but the hunkered down and kept driving. Eventually, Babcock lost cell phone signal and the livestream ended. Eatonville police, who by this point were well aware of the incident, caught up with the truck in the 8400 block of 356th Street South in Eatonville. The driver was arrested and the passenger was questioned and released. Both denied stealing the vehicle or knowing it was stolen. Two sets of keys from Sunrise Auto Sales and a stolen credit card were also recovered from the truck. Related Video

Pentagram aims to cut through the noise of EV sound design

What does an electric vehicle sound like when it goes from 0 to 60, when it signals a turn, when it’s powered down for the night? EV motors have fewer parts and are therefore incredibly silent, which presents safety concerns for drivers who recognize speed by sound and pedestrians who canÂ’t hear an approaching vehicle.  In 2019, regulators in Europe and the U.S. began requiring EVs to have warning sounds, but they left it up to the car manufacturers to choose those sounds. Many have taken the new legislation as an opportunity to not only create a branded sound, but also to stir up some marketing hype by enlisting famous musicians to compose the noise of an electric engine. Hans Zimmer created the Blade Runner-esque sound concept for BMWÂ’s i4 electric sedan, and, strangely, Linkin Park is creating EV sounds for BMW.  Sound designer Yuri Suzuki, a partner at design consultancy firm Pentagram, recently conducted a research project into the crucial role electric car sound has on a userÂ’s safety, enjoyability, communication and brand recognition, out of which he developed a range of car sounds. Suzuki says that while some automakers have chosen beautiful and interesting car sound designs, chasing celebrity clout is not the way to go when designing the sound behind serious machines.  “We really have to design carefully based on the psychological effects on a human,” Suzuki told TechCrunch. “ItÂ’s all about the relation between the human being and the machine itself.” Suzuki says smart sound design can help ease the difference between human and car by providing a shared language. Based on surveys he conducted, Suzuki came up with two new skeuomorphic electric engine sounds as well as adaptive sounds that reflect the time of day and the location of the drive.  His engine sounds are reminiscent of internal combustion engine revs, providing both drivers and pedestrians with a recognizable indication of speed increasing and decreasing. The sounds are placed at different pitches: one quite low, like a spaceship taking off; the other a bit higher, like a hovercraft vertically ascending. Audi, Ford and Jaguar Land Rover have also chosen to make futuristic copies of gasoline engines for some of their new electric vehicles.  SuzukiÂ’s sound design also includes in-car sounds, like powering on, turn signals or horn honking, that use AI to adapt to the time of day.
