When you factor in cars, trucks, planes, trains and shipping, the transportation sector is the largest source of greenhouse gases in the US. If we’re going to have any chance of addressing climate change, we’ll need to move away from burning fossil fuels in our cars. There’s just one problem with most electric vehicles: they depend on lithium-ion batteries made with heavy metals like cobalt. Not only is the material in short supply, but it’s mined in a way that involves child labor and the destruction of the environment. For those reasons, companies like IBM, Panasonic and Tesla have tried to make electric batteries without heavy metals.

So far, many of those efforts have yet to make it out of the lab, but a Chinese company called SVOLT claims it’s ready to start producing a cobalt-free battery at scale. At the Chengdu Motor Show, the firm showed off an 82.5KWh capacity power pack inside a vehicle from Chinese automaker Great Wall Motors. Under normal temperatures, SVOLT says its battery can deliver approximately 373 miles of range on a single charge and allow a car to accelerate from zero to 60 miles per hour in under five seconds.

SVOLT said the battery is “expected” to make its way to cars that go on sale in the Chinese market but didn’t offer a timeline of when that might happen, nor did it say just how many cobalt-free power packs it can manufacture at the moment. It's also worth pointing out other companies are making cobalt-free batteries at scale. As Electrek points out, most of the Model 3 units Tesla sells in China feature a lithium iron phosphate battery made by Contemporary Amperex Technology.

Back in November 2020, GM recalled over 68,000 Chevrolet Bolt EVs after five of the vehicles caught fire between 2017 and 2019. Now, the automaker has expanded the recall to cover all Bolt EVs and Bolt EUVs sold worldwide, starting from the first model up until the latest ones. This recall covers 73,000 additional vehicles, 60,000 of which are in the US, on top of the first batch of recalled Bolts. 

Upon investigating the initial incidents, GM found a manufacturing defect in the Bolt's batteries manufactured at an LG Chemical Solution plant in South Korea. That became the basis for the models the automaker included in the first recall. AP reports that GM started investigating the newer Bolts after a 2019 model that wasn't included in the recall last year caught fire in Chandler, Arizona a few weeks ago, bringing the total number of battery-related fire incidents to 10. The company found that batteries made in LG's other sites could also suffer from defects, hence the recall expansion.

GM will replace all five battery modules for models 2017 to 2019, while only defective modules will be replaced in newer vehicles. All fresh modules installed will come with a new eight year, 100,000 mile warranty. Until owners can get their cars in for module replacement, GM is advising them to limit charging to 90 percent of the battery capacity and to park outdoors. (The company previously determined that the vehicles that went up in flames were almost fully charged.) An email sent to owners contained a link to instructions on how to do just that by using the Target Charge Level mode. The automaker is also advising owners to charge their vehicle more frequently to avoid depleting their battery until there's less than 70 miles of remaining range.

This second batch of recalls will cost the company $1 billion in addition to the $800 million it's had to spend for the first one. Further, it remains to be seen how it would affect GM's EV push. In June, the automaker increased its combined EV and self-driving investment from 2020 through 2025 to $35 billion, in hopes that it can have 30 electric vehicles on the market by the end of 2025 and that it can exclusively sell EVs by 2035. For now, the company said it will stop producing and selling Bolts until it determines that there are no longer problems with LG's batteries.

Although other companies that are working on autonomous driving might get more attention, Waymo is still hard at work on the technology. The Alphabet subsidiary just provided an update on its Waymo Driver AI as well as more details about its self-driving tests.

An array of LiDAR, radar and cameras can track what's going on all around the vehicle in a variety of weather conditions, Waymo says. The system generates a 3D view of the vehicle's surroundings that humans would be able to understand. Along with other cars, the system can render pedestrians in addition to cyclists who narrowly pass by the vehicle.

The company says Waymo Driver can detect small objects and movements at a distance, such as a truck door in the middle of traffic and someone jumping out to deliver a package. It claims the AI can recognize steam emanating from utility holes and drive the vehicle through it, and understand the difference between a stop sign and its reflection.

Waymo has been testing its vehicles in San Francisco since 2009 and it ramped up its efforts in the city earlier this year. Its vehicles now clock north of 100,000 miles on SF's roads every week. Between narrow streets, drastic changes in elevation and intersections right at the top of hills, San Francisco isn't an easy city to drive in, which makes it an effective testing ground for AVs.

The company's vehicles have autonomously driven more than 20 million miles on public roads as well as 20 billion miles in simulations. That's a significant bank of data to draw from. Waymo says the AI can recognize and adapt to local driving behaviors, such as what lane to turn in at each intersection. According to the company, Waymo Driver can also mimic other vehicles' behavior, such as in SF, where people tend to drive a little slower while going up steep slopes.

Fully autonomous driving is likely several years away from going mainstream, but it seems Waymo is making significant strides toward that goal. Hopefully, Waymo Driver is getting more comfortable around safety cones.

Elsewhere, Waymo is beefing up its autonomous truck ambitions. On Wednesday, the company announced that it's building a trucking hub in Dallas-Fort Worth and partnering with Ryder to manage its fleet.

Meanwhile, Tesla's AI Day event takes place today. According to an invitation, the company will provide attendees with "an inside look at what’s next for AI at Tesla beyond our vehicle fleet." CEO Elon Musk said there'll be a live stream of the event.

General Motors and AT&T are expanding their partnership with plans to bring 5G to cars within the next few years. Some model year 2024 vehicles, which should start arriving in 2023, will be the first GM models equipped with 5G. Among GM's 2024 models is the electric Hummer SUV. GM vehicles from model year 2019 and later with 4G LTE capabilities will have faster connection speeds via the 5G network too.

The companies are building out a "high-performance 5G core network" with upgraded coverage centered on roadways. GM and AT&T claim the network will enable faster software updates and music and video downloads, as well as more responsive navigation and voice services.

Improved connectivity should benefit autonomous vehicles as well. GM says the 5G network will "provide a strong foundation" for its semi-autonomous Super Cruise tech along with its Vehicle Intelligence Platform. 

Bringing 5G connectivity to cars at a broad level was always on the cards. It'll be a while yet before there's widespread network coverage on highways and in rural areas, so adding 5G to vehicles starting in model year 2024 seems a reasonable timeline. AT&T says its 5G network is currently available in 14,000 cities and towns across the US.

Tesla could face further federal scrutiny over its Autopilot feature. Senators Ed Markey and Richard Blumenthal have called on the Federal Trade Commission to investigate the company over "misleading advertising and marketing" of the Autopilot and Full Self-Driving (FSD) systems.

"Tesla and [CEO Elon] Musk’s repeated overstatements of their vehicle’s capabilities — despite clear and frequent warnings — demonstrate a deeply concerning disregard for the safety of those on the road and require real accountability," the senators wrote in their letter to FTC chair Lina Khan. "Their claims put Tesla drivers — and all of the travelling public — at risk of serious injury or death." It's not yet clear whether the FTC will heed the senators' call and investigate the company.

Along with several examples of Tesla and Musk seemingly overselling Autopilot and FSD functions, Markey and Blumenthal cited an investigation that the National Highway Traffic Safety Administration opened this week. The agency is looking into a string of collisions between Tesla vehicles and parked emergency vehicles, one of which resulted in someone's death. The NHTSA said the Tesla vehicles in question all had Autopilot or Traffic Aware Cruise Control switched on when the crashes occurred.

Despite the name, FSD (for which Tesla charges $10,000 when a car is purchased) doesn't yet make vehicles fully autonomous. FSD, which is in beta, is currently an advanced driver assistance feature that handles maneuvers such as automatic parking, lane changing and summoning the vehicle to a nearby location. It's a Level 2 autonomous driving system, whereas full self-driving capability with no human supervision required is Level 5. Tesla notes on its website that "Autopilot does not turn a Tesla into a self-driving car nor does it make a car autonomous."

Musk has made many claims over the years about Tesla being close to offering fully autonomous capabilities. In a January earnings call, Musk said he was "highly confident the car will be able to drive itself with reliability in excess of human this year." However, a Tesla engineer later suggested the company was a long way off from rolling out Level 5 functionality.

The National Transportation Safety Board previously accused Tesla of overselling Autopilot's capabilities. In May, reports suggested the California Department of Motor Vehicles was looking into Musk's FSD claims. The names of the Autopilot and FSD features have been criticized for potentially leading drivers to overestimate their capabilities. Markey is among those who called on Tesla to change the name of Autopilot.

After all the leaks and teases, Lamborghini has finally announced its new hybrid-engine Countach. Thankfully, almost everything you need to know about the car is in its model designation: LPI 800-4. The first part is short for Longitudinale Posteriore Ibrido, referencing how the powertrain is mounted lengthwise toward the back of the supercar and the fact that it's a hybrid. Meanwhile, the two numbers point to the approximately 802 horsepower the Countach's V12 6.5-liter engine and 48-volt electric motor can output together, as well as the fact that it has four-wheel drive.        

Lamborghini

All of that makes for one powerful car. The Countach can accelerate from zero to 60 miles per hour in less than three seconds and zero to 124 miles per hour in just under nine seconds. As for a top speed, you can push it to 221 miles per hour, and it has a maximum torque of 531 lb-ft.  

Lamborghini

Powering the Countach's electric motor is a supercapacitor Lamborghini claims delivers three times more power compared to a lithium-ion battery of the same weight. The automaker says it mounted the electric motor directly to the gearbox to preserve the feeling of power transfer you get from a V12 engine.   

Carbon fiber makes up most of the chassis and exterior of the Countach LPI 800-4. "It imagines how the iconic Countach of the 70s and 80s might have evolved into an elite super sports model of this decade," Lamborghini says of the design, which is more reminiscent of the Aventador than its original namesake. Inside, you'll find an 8.4-inch touchscreen display that includes CarPlay integration and a button labeled "Stile." Pressing it "explains the Countach design philosophy to its privileged audience."  

Lamborghini

Speaking of a privileged audience, Lamborghini will only make 112 units of the Countach LPI 800-4. The press release the automaker sent over doesn't even mention a price tag. It seems Lamborghini is keen on looking forward, but the Countach was too important not to acknowledge with a limited run. 

Ford is delaying shipments of Mach-E electric vehicles due to the global chip shortage that’s causing problems across all manner of industries. The company told affected owners their deliveries will be delayed by at least six weeks.

In an effort to make up for the delay, Ford is offering an additional 250kWh worth of charging on the house, which should be good for around 700 miles of driving. That doubles the complimentary charging Mach E owners receive with their EV. According to Elektrek, the delay affects EVs that were scheduled for production between July 5th and October 1st.

“We’d like you to know that while we’re working nonstop to deliver your very own Mustang Mach-E vehicle, we project your vehicle delivery will be delayed by a minimum of six weeks," Ford wrote in an email to customers. “Once your vehicle receives the required chip, your vehicle status will be updated, and you’ll receive an email with an estimated week of delivery.”

The semiconductor shortage has impacted production of a broad range of products in recent months. Along with EVs and other vehicles, gameconsoles, graphics cards, smartphones, Apple products and other goods have been affected. Ford cut vehicle production earlier this year due to the problem.

Audi has just come out with a pretty wild EV concept: A convertible roadster that extends its wheelbase to transform into a grand tourer (GT). With the touch of a button, the Audi Skysphere's entire front end can extend or retract 9.8-inches (and drop 0.4 inches). 

The Skysphere is meant to show Audi's design chops as well as its technical prowess. It took inspiration from the company's 1931 Horch 853, a long, low roadster with a pushed-back cabin and rear-wheel drive. The modern concept retains those primary features, in spades, with the long snout and low, laid-back cockpit giving it a mild resemblance to rear-drive GTs like the Ferrari 812 Superfast. 

Audi

In place of the straight-8 gas guzzler on the Horch, the concept car has a 623-horsepower electric motor and an 80-kWh battery, with much of it behind the rear bulkhead. That makes for a Porsche 911-like rear weight bias of 60-40, meaning it would be easy to get the Skysphere sideways if it was ever built. It also delivers 553 foot-pounds of torque, enough to take it to 60 MPH in around 4 seconds. At the same time, it will go around 310 miles on the Euro WLPT cycle, or less in EPA terms. 

The interior is meant to evoke 1930s Art Deco architecture (matching the period of the Horch), with modern electronic conveniences. It has a full dashboard screen like the Honda E, along with large touchscreens at the armrest locations. The sharply angled, minimalist interior is designed for a Level 4 autonomous operation, so you can relax in GT mode and take control when you want to have some roadster-powered fun.

The most unique (though perhaps highly unrealistic) feature of the Skysphere is the variable wheelbase (above). Electric motors drive a telescoping structure that takes it from a long-wheelbase grand touring EV to a considerably shorter and lower roadster. It also uses active aerodynamics that are closed in GT mode and open in roadster form. When activated, they would duct air under the car for extra downforce.

The interior also transforms, pushing the steering wheel and pedals forward and the passenger seat rearward in roadster mode, while the dash moves forward to become a more driver-centric instrument panel. Despite the sporty nature of the EV, it has space for custom luggage and two golf club sets.  

All told, the Skysphere concept is a fun take on an EV that could be two cars at once, offering both driver fun and some autonomy if you wanted to relax. Don't expect to see one on a road near you, but some of the ideas may one day come to Audi EVs. The automaker also announced that it will unveil two other concepts, the Grandsphere and Urbansphere, in the coming months. 

Renault is looking to revive flagging sales in China. It has agreed to set up a joint venture with a major auto manufacturer in the country. Renault will share tech and resources with Geely (which owns Volvo and Polestar) to bring Renault-branded hybrid vehicles to China.

The companies plan to take advantage of Geely's supply chain and manufacturing capabilities. Renault will focus on sales and marketing.

Along with China, the companies are eyeing South Korea as a key market for their joint venture. They plan to sell localized versions of hybrids from Geely's Lynk & Co brand.

The joint venture will likely expand to other Asian markets in the future, according to Reuters, which reported that Renault and Geely are considering making fully electric vehicles as well. Renault recently announced an ambitious timeline for electrifying its vehicles. It forecasts that 65 percent of its lineup will be electric by 2025.

Having a partnership in China seems important for Renault, which has struggled to sell cars under its own name in the country. It sold just 2,324 Renault-branded cars there in 2020, a drop of 89 percent from the previous year, amid the COVID-19 pandemic and the global semiconductor shortage. In comparison, Jinbei and Huasong, brands owned by a joint venture between Renault and Brilliance Auto, sold 154,049 vehicles in China last year.

You'll have to temper your expectations if you were hoping to drive a Cybertruck before 2021 was over. Electreknotes that Tesla has quietly pushed the release of the electric pickup to next year on its configuration page, telling you that you'll get to customize your truck when "production nears in 2022." This applies regardless of model — Tesla had already warned that single-motor trucks would arrive later, but that now applies to the dual- and tri-motor machines.

Tesla had already hinted the 2021 target might not be realistic. Elon Musk said in January that there would only be a "few deliveries" of Cybertrucks in 2021, and that volume production was set for 2022. While the company stuck to that claim in its July quarterly report, the company only recently finished the engineering design for the EV — it would have just a few months to finish development and ship those initial trucks.

That could pose a competitive challenge for Tesla. GMC's Hummer EV is now poised to beat the Cybertruck to market barring delays. Even with setbacks, Rivian is still due to release its R1T truck in September. And while Ford's F-150 Lightning isn't due until spring 2022, the Cybertruck may have lost its first-mover advantage.

The delay wouldn't be surprising, though. The Cybertruck's cold-rolled steel body requires unique manufacturing techniques, and that's not including broader technical hurdles like the tri-motor system. Tesla is also known for optimistic timetables that clash with the realities of production. The automaker can at least count on pent-up demand, though. With over 1 million Cybertruck reservations, Tesla could have plenty of demand even if many of those would-be buyers have second thoughts.
