The National Highway Transportation Safety Administration announced Thursday that it is opening an investigation into the self-driving technology behind General Motors' robotaxi fleet. This announcement follows three reported accidents allegedly caused by Cruise vehicles braking hard or otherwise becoming immobilized in traffic, creating unannounced obstacles for other vehicles and resulting in rear-end collisions with other motorists.

"With respect to the incidents of hard braking, NHTSA has received three reports of the ADS initiating a hard braking maneuver in response to another road user that was quickly approaching from the rear," the agency reports, noting that human supervisors were aboard for each incident. "In each case, the other road user subsequently struck the rear of the ADS-equipped vehicle."

"With respect to the incidents of vehicle immobilization, NHTSA has been notified of multiple reports involving Cruise ADS equipped vehicles, operating without onboard human supervision, becoming immobilized," the report continues. "When this occurs, the vehicle may strand vehicle passengers in unsafe locations, such as lanes of travel or intersections, and become an unexpected obstacle to other road users."

In response the company touted its technology's history of safe operations. “Cruise’s safety record is publicly reported and includes having driven nearly 700,000 fully autonomous miles in an extremely complex urban environment with zero life-threatening injuries or fatalities," Hannah Lindow, Cruise spokesperson, told Engadget via email. "This is against the backdrop of over 40,000 deaths each year on American roads. There’s always a balance between healthy regulatory scrutiny and the innovation we desperately need to save lives, which is why we’ll continue to fully cooperate with NHTSA or any regulator in achieving that shared goal.”

The company goes on to argue that in the cases of hard braking, the vehicles were reacting to the actions of other drivers, had a human operator onboard (though the ADS was in control at the time), and has already met with the NHTSA regarding each incident. Cruise frames the immobilization events as equivalent to a flat tire, wherein the ADS encounters an unexpected and potentially dangerous situation, turns on the vehicle's hazards and pulls off to the side of the road.

Cruise LLC is headquartered in San Francisco and was founded in 2013 by Kyle Vogt and Dan Kan. GM acquired the autonomous driving technology company three years later. Since then, General Motors has lavished its subsidiary with funding, facilities and staffing, even going so far as to develop its own processor chips for the Origin autonomous shuttle bus. The company began testing ADS rides in San Francisco in June, 2021 and earlier this year earned regulatory approval to charge for driverless taxi services within the city. 

The company has also suffered setbacks in its pursuit of self-driving taxis. Division CEO Dan Ammann stepped down from his position in June, replaced for the interim by CTO and founder Kyle Vogt. Cruise made headlines in April when a police officer tried and failed to pull one over during a traffic stop and again in June when seemingly all of them decided that the corner of Gough and Fulton would make for a perfect impromptu parking lot.   

As the NHTSA is sure it's aware of every braking/immobilization incident to date, the agency is opening a preliminary evaluation,"to determine the scope and severity of the potential problem and fully assess the potential safety-related issues posed by these two types of incidents." It has not announced a timeline for publication of the PE's findings.

Ford F-150 Lightning prices are going up again. The US automaker is raising the electric pickup’s starting cost by $4,000, bringing the new entry price to $55,974. That’s a 40 percent increase over the electric vehicle’s initial starting price in May 2021.

Ford toldCNBC today that it is changing pricing “as a normal course of business due to rising material costs, market factors, and ongoing supply chain constraints.” Raw material costs of nickel, cobalt and lithium — crucial to electric car batteries — have soared alongside EV demand.

Through the end of November, Ford has only sold 13,258 F-150 Lightning units, but that number is a reflection of supply constraints rather than low demand (on the contrary, the truck is still a hot commodity). The company plans to boost production to 150,000 units by next fall — and it said earlier this week that it’s still on track to meet that goal. It recently added a third shift of workers to a Michigan production plant to help meet that goal.

Ford is the second-biggest American seller of electric vehicles (behind Tesla), and the F-150 Lightning is the top-selling electric truck. Considering Ford F-series trucks have been the best-selling vehicles in the US for three decades, that customer loyalty appears to be carrying over to EVs. Earlier this year, Engadget's Roberto Baldwin rode along for a test drive and commented on how much it felt like a standard F-150.

Starting today, human-averse travelers in Phoenix can book a fully autonomous Waymo ride between the Phoenix Sky Harbor International Airport and downtown. The Alphabet-owned company, which is also doubling its fully automated coverage area in the city, says the new route is the world’s only fully autonomous airport robotaxi service.

Waymo has accelerated its public rollout lately. In March, it received permission to charge for rides with a human safety driver in San Francisco. It also got approval last month to offer fully driverless cars there before rolling out service to the public earlier in December. San Francisco riders can now book a Waymo robotaxi across “a large portion of the city, including every neighborhood along the 17-mile Crosstown Trail.”

However, the company is still waiting for approval to charge for rider-only cars in San Francisco. It currently only offers service to Waymo employees, their guests and select members of the public. Waymo was the second fully autonomous service operating in San Francisco, behind GM-owned rival Cruise (although it only offers fully automated rides at night).

Waymo’s expansion means more Americans can book a driverless car, but it’s still modest compared to what you’ll see in China. Baidu's robotaxi service is available to the public in larger Chinese cities, although with limitations on cars without a safety driver.

Back in February, Tesla chief Elon Musk revealed on Twitter that the automaker is working to bring Steam to its vehicles. Now, the company is officially rolling out Steam integration for the latest versions of its Model S and X cars as part of its holiday update. In its promo video of the feature, you'll see Tesla's infotainment system running Steam Beta and even graphically demanding games like Cyberpunk 2077. 

By "new" Model S and X vehicles, Tesla likely means their "Plaid" versions, which started deliveries last year. Both models' infotainment systems use AMD's RDNA 2 GPUs, which are also the technology behind PlayStation 5, and AMD's Ryzen chips. Tesla has been building its library of in-vehicle games over the past few years and has added titles such as Cuphead, PUBG Mobile and Fallout Shelter to its offerings. By bringing Steam to its vehicles, though, Tesla is adding more than just a game or two to the growing list. The automaker said in its announcement that the integration will bring thousands of games to the aforementioned cars. 

Tesla previously got into trouble with the US National Highway Traffic Safety Administration (NHTSA) for allowing people to play games even while driving. It disabled the capability following the agency's investigation, however, so people most likely can't play Steam games while the vehicles are in motion. 

In addition to Steam integration, Tesla's holiday update also gives owners access to Apple Music integration for their infotainment systems. It gives them the ability to schedule Light Shows on multiple vehicles simultaneously, as well, and to view their cabin camera from the Tesla app while in Dog Mode or Sentry Mode. 

Honda is joining the ranks of automakers embracing Google's services. As teased last year, the company has announced that the 2023 Accord sedan's high-end Touring trim will be the brand's first car with Google built-in as standard. You'll have out-of-the-dealership access to Google Assistant, Google Maps and the Play Store on the vehicle's 12.3-inch infotainment display. You can tweak the climate control, navigate or download a favorite music app without relying on your phone.

There's no mention of pricing for the Google features. GM offers three free years of Google built-in access for vehicles like the GMC Yukon, but requires a $15 monthly subscription after that. You won't lose all functionality after that, though. The Accord Touring will also support Android Auto and Apple CarPlay, with a 15W wireless charger to keep your phone running.

Honda hasn't said which other cars will adopt the functionality. It won't be surprising if the Prologue EV and other future models use the technology, however. A handful of rivals already use some form of Google built-in, including Volvo, its Polestar offshoot, GM's brands and Renault. Ford will also use the platform starting in 2023.

Google has strong incentives to bring its apps to as many cars as possible — to an extent, it's racing against time. Amazon Alexa is already available in some cars, and manufacturers are gaining more control over it thanks to Custom Assistant. Apple doesn't (currently) have a standalone platform for cars, but its new generation of CarPlay can effectively take over your dash. If Google doesn't win enough partners, it risks losing influence in the automotive world.

Not everyone is happy about expansions like these. Senator Elizabeth Warren has called on the Federal Trade Commission and Justice Department to investigate Big Tech's expansion to cars. She's concerned Google and others might stifle competition by requiring service bundles and otherwise discouraging the use of third-party apps. Honda won't be affected by this political pressure in the near term, but it may get more control over app selection if regulators decide to act.

Boom has revealed more details about Symphony, the engine for the Overture jet with which it aims to bring back commercial supersonic air travel after the retirement of Concorde. Most importantly, the company has secured a new partner to develop the engine after it parted ways with Rolls-Royce in September. 

FTT, a division of Kratos Defense & Security Solutions, will help design Symphony. Some of FTT's engineers were behind the F-22 and F-35 fighter jet engines, so they have experience in powering supersonic aircraft.

Symphony is a medium-bypass turbofan engine that will have the same basic architecture as current commercial aircraft engines. However, Boom says its new propulsion system is designed to help Symphony achieve 35,000 pounds of thrust and speeds of Mach 1.7. Boom claims that Overture will be able to fly between Newark and London in under four hours and San Francisco to Tokyo in around six hours.

Boom expects Symphony to deliver a 25 percent increase in time on wing (i.e. in-flight time) and claims it will have significantly lower maintenance costs than other engines. The engine will be the first that's optimized for fully sustainable aviation fuel, Boom says, and it will operate at net zero carbon. Symphony will also have a single-stage fan that's designed for quiet operation.

Despite the switch in engine partners, Boom says the jet is still on track for certification in 2029. Production is set to start in 2024 at a factory in North Carolina with the first jet scheduled to leave the factory in 2026. Boom now expects test flights to start in 2027, a year later than previously planned. 

The company already has customers lined up. American Airlines placed an order earlier this year for 20 jets, with an option for another 40. United Airlines, meanwhile, has ordered 15 Overture planes with an option for another 35.

Juul has agreed to pay $1.2 billion to settle thousands of lawsuits – including 8,500 personal injury cases. If you think that’s a huge amount for a relatively young company, it’s got substantial financial backing: Marlboro owner, Altria, invested $12.8 billion in Juul back in 2018.

In 2018, Juul was the leader in the US e-cigarette market, but after a string of controversies, it slipped to second place behind Vuse. The US Food and Drug Administration ordered e-cigarette brands to stop selling flavored pods if they can't prove they can keep them out of minors' hands, and it attempted to ban the sale of Juul items.

Still, California sued Juul in 2019, accusing the company of targeting minors in the state, failing to verify the age of its customers and failing to warn users of their exposure to chemicals linked to cancer and birth defects.

Chevy's first hybrid Corvette leaks ahead of summer 2023 arrival

The E-Ray could pair a V8 with an electric motor to offer all-wheel drive.

Chevy

Fans on CorvetteBlogger and Corvette Forum discovered GM briefly made the 2024 Corvette E-Ray hybrid available through Chevy's online visualizer tool. The design combines the wide body of the C8 Z06 with the regular model's exhaust pipes. There are some new colors (Cacti green, anyone?) and model-specific wheels. The biggest changes, as you might guess, are in the engine. Images of the engine bay suggest the E-Ray will use the regular C8 Corvette's LT2 V8 engine. The absence of a charging port suggests this is a conventional hybrid rather than a plug-in.

Jeep parent company Stellantis on Friday said it would indefinitely shut down a manufacturing plant in Illinois and lay off approximately 1,350 employees early next year. The facility – located in Belvidere, a city 75 miles northwest of downtown Chicago – is responsible for producing the internal combustion engine Jeep Cherokee crossover. In a statement the automaker shared with Reuters, Stellantis blamed the cost of electrifying its cars for the move.

“[The automotive industry] has been adversely affected by a multitude of factors like the ongoing COVID-19 pandemic and the global microchip shortage, but the most impactful challenge is the increasing cost related to the electrification of the automotive market," the company said, adding that it may shutter the facility permanently as it considers what to do next.

United Auto Workers Local 1268 shop chairman Tim Ferguson told Reuters that company documents show Stellantis plans to move Cherokee production to a facility in Toluca, Mexico. "To me, there is no question about it," he said. "Their plan is to close this plant." Stellantis declined to comment on Ferguson’s allegations. “We are not commenting on the future of the Cherokee,” the company said.

As The Verge points out, Stellantis isn’t the first automaker to blame EVs for a recent set of layoffs. In August, Ford cut about 3,000 employees. “We have an opportunity to lead this exciting new era of connected and electric vehicles,” the automaker said at the time. “Building this future requires changing and reshaping virtually all aspects of the way we have operated for more than a century.”

It’s also worth noting Friday’s announcement came on the same day that workers at a General Motors-LG battery cell facility in Ohio voted overwhelmingly in favor of unionization. Unions in France, Italy, Canada and other parts of the world recently asked Stellantis to raise worker wages by as much as 8.5 percent following a year of record global inflation. In the third quarter of the year, Stellantis said revenue grew to €42.1 billion (approximately $44 billion), a 29 percent from the same period last year.

Chevrolet has inadvertently offered a peek at its first electrified Corvette. Fans on CorvetteBlogger, Corvette Forum and elsewhere discovered that GM briefly made the 2024 Corvette E-Ray hybrid available through Chevy's online visualizer tool. The design mates the wide body of the C8 Z06 with the regular model's exhaust pipes, and introduces minor cosmetic tweaks like new colors (Cacti green, anyone?) and model-specific wheels. The biggest changes, as you might guess, sit inside.

Images of the engine bay suggest the E-Ray will use the regular C8 Corvette's LT2 V8 engine. As Jalopnikexplains, past reports have suggested this Vette will use an electric motor on the front axle to provide all-wheel drive. It might offer a combined 605HP. The absence of a charging port suggests this is a conventional hybrid rather than a plug-in, although a glimpse of the interior shows a button to control regenerative braking. You'd also see adaptive cruise control in the lineup for the first time.

The slip-up hasn't revealed much about options. A ZER Performance Package will add Michelin Pilot Sport 4S tires, underside strakes and possibly carbon-ceramic brakes. You'll have your choices of aluminum and carbon fiber wheels, at least.

Chevy briefly confirmed the E-Ray's existence to CorvetteBlogger, noting in a statement that "the holidays came early" and asking enthusiasts to stay tuned. There's no mention of pricing, but the visualizer said the hybrid would arrive in summer 2023. The brand previously said to expect the semi-electric Corvette next year, but didn't narrow the timeframe.

This is just the start of Chevy's plans to electrify its iconic sports car. A full Corvette EV is in development, and future hybrids are rumored to include the 800HP ZR1 in 2024 and 1,000HP Zora in 2025. Like it or not, the American status symbol won't be exclusively piston-powered for much longer — not that GM has much choice when numerous states plan to ban gas car sales by 2035.

Fisker has offered a new look at the upcoming Ronin, which it claims will have the longest range of any production electric vehicle. A render of the four-door convertible has popped up on the company's website.

The image shows the Ronin from a front corner view. It has a light strip that wraps around the front. As Autoblog points out, there's no grille, but it appears as though the front bumper has some air intakes. The Ronin has a low profile and large wheels, along with dihedral front doors that are open in the render, but there's no indication as to how the rear doors open just yet.

Henrik Fisker, the founder of the automaker, said earlier this year that the Ronin will have a 660-mile range under the WLTP testing standard used in Europe. The EPA range is likely to be lower, but all going to plan, Ronin drivers should be able to travel quite a distance before needing to recharge the EV.

As things stand, Fisker plans to show off a near-production-ready Ronin concept in August, with production slated to get underway in 2024. Fisker is said to be keeping the starting price under $200,000.

At the other end of the scale, Fisker started taking reservations earlier this year for the five-passenger Pear, which starts at $29,900 before incentives. The company expects to start building that EV in 2024 as well. Last month, Fisker began production of the Ocean SUV. It will ramp up production slowly, but it expects to build approximately 42,400 units next year.
