Tesla's lousy week continues. On Tuesday, the electric car maker posted its quarterly results showing precipitous falls in sales and profitability. Today, we've learned that the National Highway Traffic Safety Administration is concerned that Tesla's massive recall to fix its Autopilot driver assist—which was pushed out to more than 2 million cars last December—has not actually made the system that much safer.

NHTSA's Office of Defects Investigation has been scrutinizing Tesla Autopilot since August 2021, when it opened a preliminary investigation in response to a spate of Teslas crashing into parked emergency responder vehicles while operating under Autopilot.

In June 2022, the ODI upgraded that investigation into an engineering analysis, and in December 2023, Tesla was forced to recall more than 2 million cars after the analysis found that the car company had inadequate driver-monitoring systems and had designed a system with the potential for "foreseeable misuse."

US electric vehicle manufacturing got a bit of a boost today. Toyota has revealed that it is spending $1.4 billion to upgrade its factory in Princeton, Indiana, in order to assemble a new three-row electric SUV. That will add an extra 340 jobs to the factory, which currently employs more than 7,500 workers who assemble the Toyota Sienna minivan and the Toyota Highlander, Grand Highlander, and Lexus TX SUVs.

"Indiana and Toyota share a nearly 30-year partnership that has cultivated job stability and economic opportunity in Princeton and the surrounding southwest Indiana region for decades," said Governor Eric Holcomb.

"Toyota's investment in the state began with an $800 million commitment and has grown to over $8 billion. Today's incredible announcement shows yet again just how important our state’s business-friendly environment, focus on long-term success, and access to a skilled workforce is to companies seeking to expand and be profitable far into the future. Indiana proudly looks forward to continuing to be at the center of the future of mobility,” Holcomb said.

Honda announced today that it will spend $11 billion to expand its electric vehicle manufacturing presence in North America. The Japanese automaker already has a number of factories in the US, Mexico, and Canada, and it's this last one that will benefit from the expansion, with four EV-related plants planned for Ontario.

Honda says it has begun evaluating requirements for what it's calling an "innovative and environmentally responsible" EV factory and a standalone EV battery plant in Alliston, Ontario, which is already home to Honda's two existing Canadian manufacturing facilities.

Additionally, the automaker wants to set up another two sites as joint ventures. One will be a plant that processes cathode active materials and their precursors—the various elements like nickel and manganese that are combined with lithium in lithium-ion batteries—set up in a partnership with POSCO Future M, a South Korean battery material and chemical company. (POSCO is already working with General Motors on another joint venture battery precursor material facility in Betancour, Quebec, that is supposed to become operational in 2026.)

California's electric grid, with its massive solar production and booming battery installations, is already on the cutting edge of the US' energy transition. And it's likely to stay there, as the state will require that all passenger vehicles be electric by 2035. Obviously, that will require a grid that's able to send a lot more electrons down its wiring and a likely shift in the time of day that demand peaks.

Is the grid ready? And if not, how much will it cost to get it there? Two researchers at the University of California, Davis—Yanning Li and Alan Jenn—have determined that nearly two-thirds of its feeder lines don't have the capacity that will likely be needed for car charging. Updating to handle the rising demand might set its utilities back as much as 40 percent of the existing grid's capital cost.

The lithium state

Li and Jenn aren't the first to look at how well existing grids can handle growing electric vehicle sales; other research has found various ways that different grids fall short. But they have access to uniquely detailed data relevant to California's ability to distribute electricity (they do not concern themselves with generation). They have information on every substation, feeder line, and transformer that delivers electrons to customers of the state's three largest utilities, which collectively cover nearly 90 percent of the state's population. In total, they know the capacity that can be delivered through over 1,600 substations and 5,000 feeders.

The Mercedes G-Wagon, a very capable off-roader typically purchased by people who never intend to take it anywhere near dirt, is getting an electric upgrade.

Unveiled in Beverly Hills—the most fitting of locations—the 2025 G 580 with EQ Technology spun its way onto the scene. The all-electric G-Wagon sports a 116 kWh capacity battery pack, four motors (one for each wheel), and a new sound system to replace the gas motor, called the G-Roar. Sadly, there's no word on price, delivery date, or range. But on paper, its impressive specs make it better than the ICE version off-road.

For serious off-roaders likely not residing in Beverly Hills, the luxury off-roader's four independent motors offer true torque vectoring and electronic differential locks. Each motor is coupled with a two-speed transmission for a reduced gear low range. The ideal use for this is rock crawling. In fact, there's an actual "Rock" crawling mode in the G 580. Mercedes is not playing.

Tesla had a terrible first quarter of 2024, according to its financial results, posted yesterday . We already knew that it was a bad three months in terms of delivering cars—the automaker built tens of thousands of cars it couldn't sell as deliveries dropped by 8.5 percent, year on year. If anything, the quarterly results paint an even worse picture.

The company has been engaged in a series of heavy price cuts, and that's showing up on the balance sheet. For all of Tesla CEO Elon Musk's statements about artificial intelligence being the future of the company, the vast majority of its income is still derived from automotive sales. These amounted to $16.5 billion in Q1, nearly $2.5 billion less than for Q1 2023. (Regulatory credits remain pretty steady at $442 million for the quarter.)

Total revenues were down by 9 percent, year on year, with gross profits down 18 percent. But the net profit, once generally accepted accounting measures were applied, fell by 55 percent to $1.1 billion. (Non-GAAP net profit was down 48 percent.)

There's a new Linux distro on the scene today, and it's a bit specialized. Its development was led by the automotive electronics supplier Elektrobit, and it's the first open source OS that complies with the automotive industry's functional safety requirements .

One of the more interesting paradigm shifts underway in the automotive industry is the move to software-defined vehicles. Cars have increasingly been controlled by electronic systems during the past few decades, but it's been piecemeal. Each added new function, like traction control, antilock braking, or a screen instead of physical gauges, required its own little black box added to the wiring loom.

There can now be more than 200 discrete controllers in a modern vehicle, all talking to each other through a CAN bus network. The idea behind the software-defined vehicle is to take a clean-sheet approach. Instead, you'll find a small number of domain controllers—what the automotive industry is choosing to call "high performance compute" platforms— each responsible for a different set of activities .

Porsche's Taycan has been a nice electric vehicle for the German brand, and the recently updated model is supposed to offer more of the good stuff and less of the bad. The sedan is on the expensive side, and it doesn't scream "family lugger," which is where the new electric Macan comes in. Porsche's volume-selling entry-level SUV is now electric, and it might be just the car to convince skeptics and non-Porsche people alike that EV is the way to go. Maybe.

At launch, you'll be able to pick up a Macan 4 or Macan Turbo. Peak power sits at 402 hp (300 k) and 630 hp (470 kW) respectively, but that's just when you use the car's overboost. Most of the time, you'll have to make do with an adequate 382 hp (285 kW) and 576 hp (430 kW). Torque for both is a healthy 479 lb-ft (650 Nm) and 833 lb-ft (1,130 Nm). With all that grunt on board, Porsche reckons you'll be able to hit 62 mph from rest in 4.9 and 3.1 seconds, respectively (0–100 km/h takes 5.2 and 3.3 seconds, respectively), as well as topping out at 137 mph (220 km/h) and 162 mph (260 km/h). Not having a gas motor under the hood isn't a penalty when it comes to performance.

The electric Macan sits on the all-new PPE (Premium Platform Electric) architecture. Shared with Audi and its upcoming Q6 e-tron , PPE was built with electricity in mind. Its party piece is a hefty 100 kWh battery (95 kWh usable) that sits under the cabin, giving the Macan 4 381 miles (613 km) of range and the Turbo 367 miles (590 km), although that's according to the less-accurate WLTP testing scheme used in Europe—EPA range estimates will be available closer to the Macan's arrival in the US in the second half of this year.

Tesla has dropped the price of its controversial "Full Self Driving" partially automated driver assist. Last week, getting access to FSD would cost you $12,000—today, it's a third cheaper at $8,000. Alternatively, customers can subscribe to the feature for $99 a month.

Tesla has bet heavily on FSD for the future of the company. It's one of two partially automated driving systems offered by Tesla—Autopilot is the older and less-capable system. FSD includes features such as auto lane changes, auto parking, the ability to summon the car from its parking space, and lane keeping (Autosteer in Tesla-speak) on surface streets.

Tesla claims that "[y]our car will be able to drive itself almost anywhere with minimal driver intervention and will continuously improve," but then also notes that "[t]he currently enabled features require active driver supervision and do not make the vehicle autonomous."
