As part of its goal to have zero-emission aircraft enter service by 2035, Airbus has announced the development of a hydrogen fuel-cell engine designed to for airplanes. Unlike Rolls-Royce's recently announced jet engine that burns hydrogen directly, it would use an electric motor just like fuel-cell cars, while emitting only H20. It could eventually be employed in commercial aircraft that could carry up to 100 passengers around 1,000 nautical miles (1,150 miles), the company said.

Airbus plans to test the engine by the middle of the decade on its A380 MSN1 aircraft, "currently being modified to carry liquid hydrogen tanks," it said. However, the technology appears to be designed for smaller, regional type aircraft that use more efficient propeller, rather than jet engines. 

"Fuel cells are a potential solution to help us achieve our zero-emission ambition and we are focused on developing and testing this technology to understand if it is feasible and viable for a 2035 entry-into-service of a zero-emission aircraft," said Airbus VP for zero-emission aircraft, Glenn Llewellyn. 

The company didn't provide any more details, but fuel-cells are a well-known technology for cars. They're far less efficient than battery electric vehicles (BEVs) if you count fuel production and conversion to electricity. However, they have more range, are faster to refuel and lighter — with the latter, of course, being essential for aircraft.  

As mentioned, Rolls-Royce just announced the successful test of a jet engine powered by burning hydrogen directly, another possible technology for future air transport. The company converted a Rolls-Royce AE 2100-A, a regional aircraft engine used in turboprop commuter planes, to work with the novel fuel source. However, the tech could theoretically be scaled up for larger planes.

There are still some major hurdles to overcome before hydrogen could ever be used to power airplanes. It takes four times as much hydrogen as regular fuel by weight for the same range, and the fuel must be kept under pressure. And of course, hydrogen is highly explosive, so aircraft systems for storage and distribution would need to be extremely reliable and durable — again adding weight. Still, it might be the only option available for aircraft in the near future, as battery technology is still much too heavy unless used for very short flights.

Tesla is working on a redesign of the Model 3 codenamed “Highland,” according to Reuters. The company’s goal is to reportedly reduce the complexity and number of components required to produce the sedan. The redesign could include changes to the car’s exterior and powertrain performance. The project is also said to build on the revamp of the 2021 Model S. However, it's unknown if the redesigned Model 3 will feature the controversial steering yoke found in its more expensive sibling.

Reuters reports Tesla’s Shanghai Gigafactory will begin producing the new Model 3 sometime during the third quarter of 2023. The company’s Fremont plant will also make the redesigned sedan. It’s unclear how much Tesla expects to save on the new Model 3, nor whether the company will pass on the cost savings to consumers. Tesla currently makes a profit of about $9,500 for every car it produces. Reuters also makes no mention of whether the refresh will feature the automaker’s next-generation 4680 battery cells. In 2020, Elon Musk said the new battery design would enable Tesla to produce a $25,000 electric car within three years.

It's safe to assume that even if the 2023 timeline is accurate, it could be subject to change. Reuters hasn’t had the best track record with its Tesla reporting recently, and it’s not like the company is great about sticking to deadlines either. When the automaker first announced the Cybertruck, for example, Elon Musk said volume production would start in 2021. That date first slipped to 2022 and then 2023.

Tesla is having a particularly lousy week. The Wall Street Journalreports the EV manufacturer has recalled a total of 80,561 cars in China over software and seat belt problems. Battery management glitches affecting 67,698 Model S and Model X vehicles could lead to unexpected stops, according to the country's State Administration for Market Regulation, while 12,863 Model 3 sedans have seat belt issues.

As with some recalls, Tesla is fixing the battery software with over-the-air updates. It's not known if the flaws have resulted in any collisions or injuries, or are directly related to past faults. In February, Tesla recalled 817,143 cars across its lineup over buggy seat belt chimes.

This is the third recall in one week for Elon Musk's outfit. Tesla recalled nearly 30,000 Model X SUVs over troublesome airbag behavior, and 321,000 Model 3 and Model Y EVs due to software-related rear light anomalies. This comes alongside numerous recalls throughout the rest of 2022, including over 1 million vehicles with pinching windows and a Full Self Driving beta oversight that let cars roll through stop signs. While Tesla has quickly released patches for software-linked bugs, the sheer number of recalls has clearly been a hassle for owners.

Recalls like these may be hurting Tesla's reputation. Consumer Reports recently placed Tesla near the bottom of its annual reliability survey. Although that's a slight improvement and reflective of teething troubles for EVs as a whole, it doesn't help Tesla's attempts to court newcomers used to a certain level of quality from conventional cars.

After gradually expanding access to its so-called full self-driving (FSD) beta for the last few years, Tesla is opening it up to anyone who has paid for it, Elon Musk announced in a tweet. "Tesla Full Self-Driving Beta is now available to anyone in North America who requests it from the car screen, assuming you have bought this option," he said. 

FSD is an extension of Tesla's "Autopilot" driver-assist feature, expanding on the latter with automated functions like automated steering in cities, automatic parking, smart vehicle summoning and traffic light/stop sign recognition. The feature is a paid upgrade priced at $15,000 following a price hike of $3,000 in September. 

Tesla first promised to launch full self-driving features in 2018, but they only finally appeared in July 2021 to a small number of "expert and careful drivers." It was released more widely in the version 9.0 beta, but testers were limited to an early access program. On the last FSD release, Tesla dropped the requirement for at least 100 Autopilot miles and an 80 safety score, and now anyone who wants it can have it. 

However, Tesla is rolling out FSD widely at a time when it's under scrutiny from regulators. The National Highway Traffic Safety Administration (NHTSA) recently expanded its investigation into a series of Tesla crashes involving first responders to most models. In a separate probe, it's also looking into more than 30 incidents involving Autopilot. 

Musk has promised full self-driving with no one behind the wheel for some time now. Most recently, he said he thought it could arrive this year, but backed off those claims in Tesla's latest earnings report. Tesla's stock has been on a steep decline of late, following Elon Musk's $44 billion purchase of Twitter. 

Tesla isn't the only car brand asking you to pay extra to unlock your car's existing capabilities. As The Vergeobserves, Mercedes has introduced a $1,200 per year "Acceleration Increase" subscription that improves the performance of the EQE and EQS in their standard sedan and SUV variants. Pay the annual fee and your 0-60MPH time will improve by 0.8 to 1 seconds thanks to a higher peak motor output and increased torque.

Mercedes is quick to explain that this is strictly a software change. In other words, you're paying to get performance your car could already handle. While you're still getting more value than BMW's $18 per month heated seats, it's an odd move when these cars are already expensive and have speedier models that only require a one-time outlay. Why buy an EQS 450 with the acceleration add-on when an EQS 580 will be faster and include more creature comforts in the bargain?

The German automaker isn't the first to charge extra for added performance. Tesla has long asked customers to shell out for its most advanced driver assists. For a while, it also charged entry Model S buyers a premium to unlock battery capacity. And if you're more inclined toward motorcycles, Zero asks nearly $1,800 to maximize the power of the 2022 SR. The difference, of course, is that those are still one-off purchases where Mercedes wants you to keep paying for the life of the car.

The business strategy is clear. As with the tech world's general shift toward subscription services, Mercedes is hoping for a steady stream of revenue from customers who might otherwise spend little beyond the initial purchase. Acceleration Increase is decidedly more lucrative than periodic navigation updates and maintenance. Unlike those, though, there's no recurring costs to help justify the power boost's existence.

Tesla is recalling more than 321,000 vehicles over a software issue that causes the tail lights on some cars not to work properly. The automaker announced the action on Saturday in a National Highway Traffic and Safety Administration filing (PDF) spotted by Reuters. The recall covers 2023 Model 3 and 2020 to 2023 Model Y vehicles manufactured for US customers.

“In rare instances, taillamps on one or both sides of affected vehicles may intermittently illuminate due to a firmware anomaly that may cause false fault detections during the vehicle wake up process,” the NHTSA notice states. “Brake lamps, backup lamps and turn signal lamps are not affected by this condition and continue to operate as designed.”

Tesla will release a software update to address the issue. The company hasn’t had reports of any crashes or injuries related to the bug. The automaker became aware of the problem in late October. In a separate announcement the day before, Tesla recalled about 30,000 due to an issue that can cause the front passenger airbag in Model X vehicles to deploy incorrectly in some situations.

As of this year, Tesla has so far issued 19 recalls in the US. Earlier this month, the company recalled 40,186 Model S and Model X vehicles over a software issue that could cut power steering assistance to vehicles going over potholes. Before that, the company recalled more than a million vehicles over windows that weren't working properly.

Tesla has issued a recall for 29,348 Model X vehicles, because their airbag might deploy incorrectly in some situations. This recall affects 2021 to 2023 Model X cars manufactured for customers in the US. According to the recall notice (PDF) published by the National Highway Traffic Safety Administration (NHTSA), the restraint control module calibration on those specific vehicles could cause the frontal passenger airbag to deploy "in an unintended configuration during certain low-speed collision events."

While the notice didn't illustrate the airbag's "unintended configuration," it said that it would result in noncompliance of the law when a child around three to six years old is seating in the front passenger seat without a seatbelt and out of position. Reuters notes Tesla's shares fell by 3 percent after the recall was published, leading to its lowest in nearly two years, but it's worth noting that the company says it's not aware of any "warranty claims, field reports, crashes, injuries, or deaths related to this condition."

Earlier this month, Tesla also recalled 40,168 Model S and Model X vehicles over a software defect that could potentially cut power steering assistance due to potholes and other bumps on the road. And in September, it issued a recall for over a million vehicles because their window automatic reversal system could malfunction and pinch the driver or passenger. 

Like those other recalls, though, owners don't have to turn their vehicles in or go anywhere for a fix at all. The issue can be fixed by an over-the-air firmware update, which the automaker will roll out to all affected vehicles. 

Waymo is one step closer to charging passengers for fully driverless rides in San Francisco. The California Public Utilities Commission (CPUC) has granted the company a Driverless Pilot permit, which allows it to pick up passengers in a test vehicle without a driver behind the wheel. It's only the second participant in the CPUC's Driverless Permit program, with Cruise being the first. 

By securing the permit, Waymo now has the authority to offer driverless rides throughout San Francisco, portions of Daly City, as well as in portions of Los Altos, Los Altos Hills, Mountain View, Palo Alto and Sunnyvale. Its vehicles are allowed to go as fast as 65 miles per hour and can operate 24/7, but the company can't charge for the rides just yet. Waymo told Engadget that it will begin offering free rides without a driver to select members of the public in the coming weeks. To note, the company has been offering free driverless rides to the public in Phoenix since 2020. 

The California Department of Motor Vehicles recently authorized Waymo to charge for fully autonomous rides. However, the company still has to secure a Driverless Deployment permit — the next step after this one — from the CPUC to be able to start doing so. The agency gave Cruise a deployment permit for robotaxis in June, almost a year after it was allowed to offer free rides to the public. 

Like Cruise, Waymo likely won't be allowed to operate its vehicles during times of heavy fog and rain when it gets its deployment permit. Robotaxi companies have to find a way to overcome autonomous vehicles' performance issues in bad weather, however, if they want to be able to service more places and more people. Waymo is taking steps to address the problem and recently announced that it's using its latest car sensor arrays to create real-time weather maps of Phoenix and San Francisco. The Alphabet-owned company will use the data it gathers to improve its Driver AI's ability to handle rough weather and to better understand the limits of its vehicles. 

After years of buildup, Fisker has finally started building its ambitious electric Ocean SUV in Austria. The company pledged to start production by the end of 2022, so it has met that target with around six weeks to spare.

If you didn't lock in a pre-order for the EV swiftly, you may still be in for quite a wait before you get your hands on the Ocean. Fisker will ramp up production gradually. It plans to build more than 300 units in the first quarter of 2023, increasing to more than 8,000 the following quarter. For Q3, the aim is to make more than 15,000 units. All told, Fisker expects to assemble around 42,400 units in 2023.

Two of the Ocean trims have sold out in the US for 2023 and the company has received more than 63,000 reservations in total. The limited-edition Ocean One trim, which is based on the high-end Ocean Extreme, required a $5,000 deposit and sold out within 30 days earlier this year. Fisker will crank out 5,000 units of the Ocean One before moving on to other variants.

The Ocean Extreme, which starts at $68,999, is capable of traveling 350 miles on a single charge, according to Fisker. The SUV boasts what the company claims is the first digital radar system as a safety feature. The Ocean Extreme has dual-motor, all-wheel-drive with 550 horsepower, which can accelerate the vehicle from 0 to 60 mph in 3.6 seconds. It also includes three driving modes, a 17.1-inch rotating screen you can play games on and a solar roof.

The base-level Ocean Sport is selling for $37,499, while the mid-tier Ocean Ultra will set you back $49,999. The Sport has one 275 hp engine that can take the car from 0 to 60 mph in 6.6 seconds. The dual-motor Ultra has 540 horsepower and a 0 to 60 mph time of 3.9 seconds.

Fisker claims the Ocean is the planet's "most sustainable vehicle." The SUV is being assembled in a carbon-neutral factory. The vehicle also includes more than 50 kg (110 pounds) of recycled, biodegradable and overall eco-conscious materials.

Toyota impressed many onlookers this week with a sleeker redesign for the Prius. It turns out that the 2023 Prius Prime, the plug-in hybrid model, is also getting the new look as well as some other upgrades. For one thing, Toyota says that a larger lithium-ion battery will improve on the previous model's EV range of 25 miles by over 50 percent (i.e. to at least 37.5 miles). As such, you'll be able to take longer trips before starting to use gas.

Another neat feature is the solar roof. These panels can recharge the battery when the Prius Prime is parked. When you're on the road, the solar roof can provide auxiliary power to functions like air conditioning to lessen the load on the lithium-ion battery. Toyota adds that the solar panels' electrodes are concealed to maintain the plug-in hybrid's sleek look. "A focus for Prius Prime is to allow it to have a similar ethos to the new Prius hybrid model, but with a little something extra — more performance, technology, safety and even a little attitude," the automaker said.

Toyota

The 2023 model is lighter and more rigid than previous ones, Toyota claims, while it has a low center of gravity and larger luggage capacity. The vehicle is two inches lower, an inch wider and an inch longer than the previous Prius Prime, with a hip point that's nearly an inch lower too.

In terms of performance, Toyota says the fifth-generation hybrid powertrain and 2.0-liter engine help deliver a horsepower increase of nearly 100 hp over the last-gen model to 220 hp. The vehicle can seemingly go from 0 to 60 mph in 6.6 seconds too.

As with the base Prius, the Prius Prime supports both Apple CarPlay and Android Auto. Toyota's own Intelligent Assistant enables you to search for directions, tweak audio settings, change cabin temperatures and more with voice commands. To help you figure out how to get to where you're going, the Cloud Navigation system uses the latest available map, traffic and routing information. Alternatively, you can get some help from a live agent via Destination Assist.

Other features include a JBL Premium Audio system with eight speakers and six USB-C ports. A digital key system is available on some trims as part of the Remote Connect service, enabling you to lock and unlock doors, start the engine and more with your phone.

Toyota

Elsewhere, the Prius Prime comes with Blind Spot Monitor with Rear Cross Traffic Alert as standard on all trims. Front and Rear Parking Assist with Automatic Braking is available as an option on SE variants and as standard on the XSE and XSE Premium grades. Those who opt for the XSE Premium trim will have the option to use a Panoramic View Monitor feature that allows for a live rotating 360-degree view around the vehicle, as well as a hands-free system that can help with parallel parking and reversing into a parking space.

Although Toyota will announce pricing and availability for the base Prius by the end of the year, you'll need to wait longer to find out that info for the Prius Prime. The company says it will reveal pricing and the on-sale date for the plug-in hybrid in the first half of 2023.
