Automakers excoriated by Senators for fighting right-to-repair

Yesterday, US Senators Jeff Merkley (D-OR), Elizabeth Warren (D-MA), and Joshua Hawley (R-MO) sent letters to the heads of Ford, General Motors, and Tesla, as well as the US heads of Honda, Hyundai, Nissan, Stellantis, Subaru, Toyota, and Volkswagen, excoriating them over their opposition to the right-to-repair movement.

“We need to hit the brakes on automakers stealing your data and undermining your right-to-repair,” said Senator Merkley in a statement to Ars. “Time and again, these billionaire corporations have a double standard when it comes to your privacy and security: claiming that sharing vehicle data with repair shops poses cybersecurity risks while selling consumer data themselves. Oregon has one of the strongest right-to-repair laws in the nation, and that’s why I’m working across the aisle to advance efforts nationwide that protect consumer rights.”

Most repairs aren’t at dealerships

The Senators point out that 70 percent of car parts and services currently come from independent outlets, which are seen as trustworthy and providing good value for money, “while nearly all dealerships receive the worst possible rating for price.”

OEMs and their tier-one suppliers restricting the supply of car parts to within their franchised dealership networks also slows down the entire repair process for owners as well as increasing the cost of getting one’s car fixed, the letter states.

As Ars noted recently, more than one in five automotive recalls are now fixed with software patches, and increasingly the right-to-repair fight has centered on things digital—access to diagnostics, firmware, and connected services. The percentage of non-hardware recall fixes will surely grow in the coming years as more and more automakers replace older models with software-defined vehicles.

Here’s what we learned driving Audi’s new Q6 and SQ6 electric SUVs

HEALDSBURG, Calif.—Earlier this summer, Ars got its first drive of Audi’s new Q6 e-tron on some very wet roads in Spain. Then, we were driving pre-production Q6s in Euro-spec. Now, the electric SUV is on sale in the US, with more power in the base model and six months more refinement for its software. But the venue change did not bring a change of weather—heavy rain was the order of the day, making me wonder if Audi is building its new electric vehicle on the site of an ancient rain god’s temple?

Of all its rivals, Audi appears to have settled into a nomenclature for its vehicles that at least makes a little sense. Odd numbers are for internal combustion engines, even numbers for EVs, although it also appends “e-tron” on the end to make that entirely clear… and give francophones something to snicker about. (Yes, the e-tron GT does not fit into this schema, but nobody’s perfect.)

The Q6 e-tron is also the most advanced EV to wear Audi’s four rings. Built on a new architecture called PPE (premium platform electric), at its heart is an 800 V powertrain with a 100 kWh (94.4 kWh useable) lithium-ion battery pack that powers a permanently excited synchronous motor driving the rear wheels, and in the case of the quattro versions, an asynchronous motor. The electric motors have 30 percent less energy consumption than those used in the Q8 e-tron, and are smaller and lighter.

That makes it a lot more up to date than the Q8 e-tron, which uses a modified version of Audi’s venerable MLB Evo platform, or the smaller Q4 e-tron, a somewhat disappointing electric crossover that’s essentially a Volkswagen ID.4 with a glow-up. That goes for the Q6 e-tron’s electronics, which are also a generation newer than the Q4 e-tron, and also more capable.

Audi is starting off US Q6 e-tron sales with a pair of models, the $65,800 Q6 e-tron quattro and the $72,900 SQ6 e-tron quattro. A $63,800 single-motor (not-quattro) Q6 e-tron will be available in time, with 302 hp (225 kW) and an EPA range of 321 miles (517 km), but we’ll have to wait a while before we get behind the wheel of that one.

Here’s the new hybrid Honda Prelude, on sale late 2025

The fact that Honda was working on a new Prelude coupe was not entirely secret—not after the automaker unveiled a show car at this year’s Long Beach Grand Prix. This morning, the Japanese automaker confirmed that the new Prelude will go on sale here in the US late in 2025.

“The return of the Honda Prelude as a hybrid-electric sports model demonstrates our continued commitment to offer a variety of exhilarating products to meet the needs of our customers,” said Jessika Laudermilk, assistant vice president of Honda Auto Sales. “The first three products in the Honda lineup in the 1970s were Civic, Accord, and Prelude, and soon all three will be back together again in our passenger car lineup as hybrids.”

Honda has often used the two-door Prelude coupe as a testbed for new technologies, including torque vectoring and four-wheel steering, and was praised by the late automotive writer LJK Setright, who owned several Preludes across the years.

An innovation in the next Prelude will be a new drive mode, called Honda S+ Shift, which it says “advances linear shift control to deliver maximum levels of driver engagement.” But as the Prelude will use a hybrid powertrain, there won’t be an option for a manual transmission in this generation.

Beyond that, Honda is keeping quiet on Prelude details until closer to the car’s arrival on sale next year.

Trump to block the government and military from buying EVs

The incoming Trump administration has even more plans to delay electric vehicle adoption than previously thought. According to Reuters, which has seen transition team documents, the Trump team wants to abolish EV subsidies, claw back federal funding meant for EV charging infrastructure, block EV battery imports on national security grounds, and prevent the federal government and the US military from purchasing more EVs.

During the campaign, candidate Trump made repeated references to ending a supposed EV mandate. In fact, policies put in place by current US President Joe Biden only call for 50 percent of all new vehicles to be electrified by 2032 under EPA rules meant to cut emissions by 56 percent from 2026 levels.

More pollution

Instead, the new regime will be far more friendly to gas guzzling, as it intends to roll back EPA fuel efficiency standards to those in effect in 2019. This would increase the allowable level of emissions from cars by about 25 percent relative to the current rule set. US new vehicle efficiency stalled between 2008 and 2019, and it was only once the Biden administration began in 2021 that the EPA started instituting stricter rules on allowable limits of carbon dioxide and other pollutants from vehicle tailpipes.

About a third of the population looks to the California Air Resources Board, rather than the EPA, to get their emissions regulations.

The so-called ZEV states (for Zero Emissions Vehicles) do have something closer to an EV mandate, and from model-year 2026 in these states (California, Connecticut, Colorado, Delaware, Maine, Maryland, Massachusetts, Minnesota, Nevada, New Jersey, New York, Pennsylvania, Oregon, Rhode Island, Vermont, Virginia, Washington, and the District of Columbia) a third of all new cars sold by each automaker will have to be battery-electric—assuming the EPA grants California a waiver to allow this to happen.

As with the first Trump administration, we can expect a sustained attack on California’s ability to set its own vehicle emissions regulations and any attempts by other states to use those regs.

More tariffs

Trade tariffs will evidently be a major weapon of the next Trump administration, particularly when deployed to block EV manufacturing. Even the current administration has been wary enough of China dumping cheap EVs that it instituted singeing tariffs on Chinese-made EVs and batteries, with bipartisan support from Congress.

Amazon starts selling Hyundai cars, more brands next year

Fear not—there’s no one-click option, so no one should be in any danger of absent-mindedly buying a brand-new Palisade. Instead, there’s a “Begin Purchase” button, at which point you can choose to pay the entire amount or finance the purchase.

Here is a huge difference to the traditional dealership experience: There’s no negotiation, no browbeating or asking you how much of a monthly payment you want to make, and no upselling paint protection or the like. Everything can be done through amazon with a few clicks, ending with scheduling a pick-up time for the new car at the dealership. You can even trade in your existing car during the process. (I only tested it so far lest I accidentally end up with a brand-new Ioniq 5 N, which I still can’t charge at home.)

Amazon says it will add more brands next year, as well as leasing, and will also expand to more cities. For now, Amazon Autos is available in Atlanta, Austin, Baltimore, Beaumont-Port Arthur, Birmingham, Boston, Champaign/Springfield, Charlotte, Chicago, Cincinnati, Cleveland, Columbia, Columbus, Dallas, Denver, El Paso, Fond Du Lac, Ft. Myers/Naples, Harrisburg-Lancaster-Lebanon-York, Harrisonburg, Hartford, Houston, Indianapolis, Jacksonville, Los Angeles, Miami, Milwaukee, Minneapolis-St. Paul, Nashville, New York, Orlando, Philadelphia, Phoenix, Pittsburgh, Portland, Providence, Raleigh-Durham, Salt Lake City, San Antonio, San Diego, San Francisco, Seattle, Sheboygan, Springfield, St. Louis, Tampa, West Palm Beach, and Washington, DC.

ev-charging-infrastructure-isn’t-just-for-road-trippers

EV charging infrastructure isn’t just for road trippers

Although there’s been a whole lot of pessimism recently, electric vehicle sales continue to grow, even if it is less quickly than many hoped. That’s true in the commercial vehicle space as well—according to Cox Automotive, 87 percent of vehicle fleet operators expect to add EVs in the next five years, and more than half thought they were likely to buy EVs this year. And where and when to plug those EVs in to charge is a potential headache for fleet operators.

The good news is that charging infrastructure really is growing. It doesn’t always feel that way—the $7.5 billion allocated under the Inflation Reduction Act for charging infrastructure has to be disbursed via state departments of transportation, so the process there has been anything but rapid. But according to the Joint Office of Energy and Transportation, the total number of public charging plugs has doubled since 2020, to more than 144,000 level 2 plugs and closing in on 49,000 DC fast charger plugs.

There are ways to throw off a planned timeline when building out a station with multiple chargers. Obviously you need the funds to pay for it all—if these are to come from grants like the National Electric Vehicle Infrastructure program, that had to wait for the states to each develop their own funding plans, then open for submissions, and so on, before even approving a project, for example.

Permitting can add plenty more delays, and then there’s the need to run sufficient power to a site. “The challenge is getting the power to the points that it needs to be used. The good thing is that the rollout for EV is not happening overnight, and it’s staged. So that does give some opportunity,” said Amber Putignano, market development leader at ABB Electrification.

For example, ABB has been working with Greenlane, a $650 million joint venture between Daimler Truck North America, NextEra Energy Resources, and BlackRock, as it builds out a series of charging corridors along freight routes, starting with a 280-mile (450 km) stretch of I-15 between Los Angeles and Las Vegas.

2025 Lamborghini Urus SE first drive: The total taurean package


A 789-horsepower Goldilocks moment

Adding electric power and a battery turns the Urus from hit-or-miss to just right.

The original Urus was an SUV that nobody particularly wanted, even if the market was demanding it. With luxury manufacturers tripping over themselves to capitalize on a seemingly limitless demand for taller all-around machines, Lamborghini was a little late to the party.

The resulting SUV has done its job, boosting Lamborghini’s sales and making up more than half of the company’s volume last year. Even so, the first attempt was just a bit tame. That most aggressive of supercar manufacturers produced an SUV featuring the air of the company’s lower, more outrageous performance machines, but it didn’t quite deliver the level of prestige that its price demanded.

The Urus Performante changed that, adding enough visual and driving personality to make itself a legitimately exciting machine to drive or to look at. Along the way, though, it lost a bit of the most crucial aspect of an SUV: everyday livability. On paper, the Urus SE is just a plug-in version of the Urus, with a big battery adding some emissions-free range. In reality, it’s an SUV with more performance and more flexibility, too. This is the Urus’ Goldilocks moment.

The what

The Urus SE starts with the same basic platform as the other models in the line, including a 4.0 L turbocharged V8 that drives all four wheels through an eight-speed automatic and an all-wheel-drive system.

All that has received a strong dose of electrification, starting with a 25.9 kWh battery pack sitting far out back that helps to offset the otherwise nose-heavy SUV while also adding a playful bit of inertia to its tail. More on that in a moment.

That battery powers a 189 hp (141 kW) permanent-magnet synchronous electric motor fitted between the V8 and its transmission. The positioning means it has full access to all eight speeds and can drive the car at up to 81 mph (130 km/h). That, plus a Lamborghini-estimated 37 miles (60 km) of range, means this is a large SUV that could feasibly cover a lot of people’s commutes emissions-free.

But when that electric motor’s power is paired with the 4.0 V8, the result is 789 hp (588 kW) total system power delivered to all four wheels. And with the electric torque coming on strong and early, it not only adds shove but throttle response, too.

Other updates

At a glance, the Urus SE looks more or less the same as the earlier renditions of the same SUV. Look closer, though, and you’ll spot several subtle changes, including a hood that eases more gently into the front fenders and a new spoiler out back that Lamborghini says boosts rear downforce by 35 percent over the Urus S.

Far and away the most striking part of the car, though, are the 22-inch wheels wrapped around carbon-ceramic brakes. They give this thing the look of a rolling caricature of a sport SUV in the best way possible. On the body of the machine itself, you’ll want to choose a properly eye-catching color, like the Arancio Egon you see here. I’ve been lucky to drive some pretty special SUVs over the years, and none have turned heads like this one did when cruising silently through a series of small Italian towns.

Things are far more same-y on the inside. At first blush, nothing has changed inside the Urus SE, and that’s OK. You have a few new hues of Technicolor hides to choose from—the car you see here is outfitted in a similarly pungent orange to its exterior color, making it a citrus dream through and through. The sports seats aren’t overly aggressive, offering more comfort than squeeze, but I’d say that’s just perfect.

Buttons and touchscreens vie with less conventional controls inside the Urus. Tim Stevens

But that’s all much the same as prior Urus versions. The central infotainment screen is slightly larger at 12.3 inches, and the software is lightly refreshed, but it’s the same Audi-based system as before. A light skinning full of hexagons makes it look and feel a little more at home in a car with a golden bull on the nose.

Unfortunately, while the car is quicker than the original model, the software isn’t. The overall experience is somewhat sluggish, especially when moving through the navigation system. Even the regen meter on the digital gauge cluster doesn’t change until a good half-second after you’ve pressed the brake pedal, an unfortunate place for lag.

The Urus SE offers six drive modes: Strada (street), Sport, Corsa (track), Sabbia (sand), Terra (dirt), and Neve (snow). There’s also a seventh, customizable Ego mode. As on earlier Urus models, these modes must be selected in that sequence. So if you want to go from Sport back to Strada, you need to cycle the mode selector knob five times—or go digging two submenus deep on the touchscreen.

Those can be further customized via a few buttons added beneath the secondary drive mode lever on the right. The top button enables standard Hybrid mode, where the gasoline and electric powertrains work together as harmoniously as possible for normal driving. The second button enters Recharge mode, which instructs the car to prioritize battery charge. The third and lowest button enters Performance mode, which gives you maximum performance from the hybrid system at the expense of charge.

Finally, a quick tug on the mode selector on the right drops the Urus into EV Drive.

Silent running

I started my time in the Urus SE driving into the middle of town, which was full of narrow streets, pedestrian-friendly speed limits, and aggressively piloted Fiats. Slow and steady is the safest way in these situations, so I was happy to sample the Urus’ all-electric mode.

To put it simply, it delivers. There’s virtually no noise from the drivetrain, a near-silent experience at lower speeds that help assuage the stress such situations can cause. The experience was somewhat spoiled by some tire noise, but I’ll blame that on the Pirelli Scorpion Winter 2 tires outfitted here. I can’t, however, blame the tires for a few annoying creaks and rattles, which isn’t exactly what I’d expect from an SUV at this price point.

Though there isn’t much power at your disposal in this mode, the Urus can still scoot away from lights and stop signs quickly and easily, even ducking through small gaps in tiny roundabouts.

Dip more than three-quarters of the way into the throttle, though, and that V8 fires up and quickly joins the fun. The hand-off here can be a little less than subtle as power output surges quickly, but in a moment, the car goes from a wheezy EV to a roaring Lamborghini. And unlike a lot of plug-ins that stubbornly refuse to shut their engines off again when this happens, another quick pull of the EV lever silences the thing.

When I finally got out of town, I shifted over to Strada mode, the default mode for the Urus. I found this mode a little too lazy for my tastes, as it was reluctant to shift down unless I dipped far into the throttle, resulting in a bucking bull of acceleration when the eight-speed automatic finally complied.

The car only really came alive when I put it into Sport mode and above.

Shifting to Sport

Any hesitation or reluctance to shift is quickly obliterated as soon as you tug the drive mode lever into Sport. The SUV immediately forgets all about trying to be efficient, dropping a gear or two and making sure you’re never far from the power band, keeping the turbo lag from the V8 to a minimum.

The tachometer gets some red highlights in this mode, but you won’t need to look at it. There’s plenty of sound from the exhaust, augmented by some digital engine notes I found to be more distracting and unnecessary than anything. Most importantly, the overall feel of the car changes dramatically. It leaps forward with the slightest provocation of the right pedal, really challenging the grip of the tires.

In my first proper sampling of the full travel of that throttle pedal, I was surprised at how quickly this latest Urus got frisky, kicking its tail out with an eager wag on a slight bend to the right. It wasn’t scary, but it was just lively enough to make me smile and feel like I was something more than a passenger in a hyper-advanced, half-electric SUV.

Credit: Tim Stevens

In other words, it felt like a Lamborghini, an impression only reinforced as I dropped the SUV down to Corsa mode and really let it fly. The transmission is incredibly eager to drop gears on the slightest bit of deceleration, enough so that I rarely felt the need to reach for the column-mounted shift paddles.

But despite the eagerness, the suspension remained compliant and everyday-livable in every mode. I could certainly feel the (many) imperfections in the rural Italian roads more when the standard air suspension was dialed over to its stiffest, but even then, it was never punishing. And in the softest setting, the SUV was perfectly comfortable despite those 22-inch wheels and tires.

I didn’t get a chance to sample the SUV’s off-road prowess, but the SE carries a torque-vectoring rear differential like the Performante, which should mean it will be as eager to turn and drift on loose surfaces as that other, racier Urus.

Both the Urus Performante and the SE start at a bit over $260,000, which means choosing between the two isn’t a decision to be made on price alone. Personally, I’d much prefer the SE. It offers plenty of the charm and excitement of the Performante mixed with even better everyday capability than the Urus S. This one’s just right.

The 2025 BMW i5 M60 review: An EV that makes you want to drive and drive

In fact, I think the cheaper, less powerful i5 eDrive40 (or the all-wheel drive xDrive40) is the better i5, but BMW didn’t have one of those available in the press fleet, so a review of that version will have to wait for one to show up. As I often write, the most powerful version of any given EV is usually a worse deal, as they’re invariably fitted with big, range-sapping wheels, and it’s not like a 0–60 time of 5.7 seconds is particularly slow, even by 2024’s standards.

And those big wheels cause a range hit—the EPA rates the i5 M60 at 240 miles (386 km) on a full charge, although in Efficient mode that should be beatable—according to our test car, over 1,000 miles (1,609 km), it averaged 3.2 miles/kWh (19.4 kWh/100 km). Then again, if you stick it in Sport mode and hoof the throttle too often, it’s not hard to see that number plummet to 2.4 miles/kWh (25.9 kWh/100 km).

As the latest version of BMW’s fifth-gen EV powertrain, the i5 has its most up-to-date fast charging software, which uses a new control strategy to maintain higher levels of power for longer while plugged into a DC fast charger, even when starting at a state of charge as high as 50 percent. During our testing, we fast-charged the i5 from 19 to 91 percent, which took a couple of seconds more than 37 minutes, delivering 62 kWh and peaking at an impressive 209 kW, although before long power delivery dropped to 150 kW.

Software-defined emotions

Sport mode is fast and sounds good, accompanied as it is by Hans Zimmer-crafted powertrain sounds. And Efficient, which mostly just relies on the 335 hp (250 kW), 317 lb-ft (430 Nm) rear motor, is quiet and comfortable. But the i5 offers you some other choices, including Expressive, Relax, and Digital Art modes, which reconfigure the cabin lighting, the dynamic wallpaper on the curved display, and the powertrain sounds.

lower-cost-sodium-ion-batteries-are-finally-having-their-moment

Lower-cost sodium-ion batteries are finally having their moment

In contrast, a sodium-ion battery relies on an element—sodium—that you can find in table salt and ocean water.

Among the other benefits, sodium-ion batteries perform better than lithium-ion batteries in extreme cold. CATL has said its new battery works in temperatures as low as -40° Fahrenheit.

Also, a sodium-ion battery has much lower risk of fire. When lithium-ion batteries sustain damage, it can lead to “thermal runaway,” which triggers a dangerous and toxic fire.

The process of manufacturing sodium-ion batteries is similar to that of lithium-ion batteries, or at least similar enough that companies can shift existing assembly lines without having to spend heavily on retooling.

But sodium-ion batteries have some disadvantages. The big one is low energy density compared to lithium-ion. As a result, an EV running on a sodium-ion battery will go fewer miles per charge than a lithium-ion battery of the same size.

“That is just what nature has given us,” Srinivasan said. “From a physics perspective, sodium batteries inherently have lower energy density than lithium batteries.”

A typical sodium-ion battery has an energy density of about 150 watt-hours per kilogram at the cell level, he said. Lithium-ion batteries can range from about 180 to nearly 300 watt-hours per kilogram.

I asked Srinivasan what he makes of CATL’s claim of a sodium-ion battery with 200 watt-hours per kilogram.

“We tend to be skeptical of news releases from companies,” he said. He specified that his comment applies to all battery companies.

The national labs’ initiative has a five-year timeline, with a goal of developing sodium-ion batteries with energy densities that match or exceed those of today’s iron phosphate-based lithium-ion batteries. Researchers would do this by finding various efficiencies in design and materials.

The project is happening alongside the labs’ ongoing work to develop and improve other kinds of batteries.

Lithium-ion batteries dominate today’s market. This year, global production of lithium-ion batteries was about 1,500 gigawatt-hours, and production of sodium-ion batteries was 11 gigawatt-hours, or less than 1 percent, according to Benchmark Mineral Intelligence.

No more EV app folders: Universal plug-and-charge is due to launch in 2025

To fill a car with gas, you generally just need a credit card or cash. To charge an EV at a DC fast charging station, you need any number of things to work—a credit card reader, an app for that charger’s network, a touchscreen that’s working—and they’re all a little different.

That situation could change next year if a new “universal Plug and Charge” initiative from SAE International, backed by a number of EV carmakers and chargers, moves ahead and gains ground. Launching in early 2025, the network could make charging an EV actually easier than gassing up: plug in, let the car and charger figure out the payment details over a cloud connection, and go.

Some car and charging network combinations already offer such a system through a patchwork of individual deals, as listed at Inside EVs. Teslas have always offered a plug-and-charge experience, given the tight integration between their Superchargers and vehicles. Now Tesla will join the plug-and-charge movement proper, allowing Teslas to have a roughly similar experience at other stations.

The Electric Vehicle Public Key Infrastructure, or EVPKI, has a good number of the major players on board, and it builds on the ISO standard (15118) to make it faster and more secure for cars to be authenticated and authorized to charge at stations. A whole bunch of certificates are in place at every step of the charging process, as detailed in an EVPKI presentation, and the system includes a Certified Trust List. With an open standard and authentication system, there should be room for new charging networks and vehicle makers.

after-telling-cadillac-to-pound-sand,-f1-does-180,-grants-entry-for-2026

After telling Cadillac to pound sand, F1 does 180, grants entry for 2026

The United States will have a second team competing in Formula 1 from 2026, when Cadillac Formula 1 will join the sport as its 11th team. The result is a complete 180 for the sport’s owner, which was highly resistant to the initial bid, first announced at the beginning of 2023.

“As the pinnacle of motorsports, F1 demands boundary-pushing innovation and excellence. It’s an honor for General Motors and Cadillac to join the world’s premier racing series, and we’re committed to competing with passion and integrity to elevate the sport for race fans around the world,” said GM President Mark Reuss. “This is a global stage for us to demonstrate GM’s engineering expertise and technology leadership at an entirely new level.”

Team first, engines later

We will have to wait until 2028 to see that full engineering potential on display. Even with the incoming changes to the technical regulations, it’s far more than the work of a minute to develop a new F1 hybrid powertrain, let alone a competitive package. Audi has been working on its F1 powertrain since at least 2023, as has Red Bull, which decided to make its internal combustion engine in-house, like Ferrari or Mercedes, with partner Ford providing the electrification.

GM’s decision to throw Cadillac’s hat into the ring came with the caveat that its powertrain wouldn’t be ready until 2028—two years after it actually wants to enter the sport. That means for 2026 and 2027, Cadillac F1 will use customer engines from another manufacturer, in this case Ferrari. From 2028, we can expect a GM-designed V6 hybrid under Cadillac F1’s engine covers.

As McLaren has demonstrated this year, customer powertrains are no impediment to success, and Alpine (née Renault) is going so far as to give up its own in-house powertrain program in favor of customer engines (and most likely, a for sale sign as the French automaker looks set to walk away from the sport once again).

automatic-braking-systems-save-lives-now-they’ll-need-to-work-at-62-mph.

Automatic braking systems save lives. Now they’ll need to work at 62 mph.

Otherwise, drivers will get mad. “The mainstream manufacturers have to be a little careful because they don’t want to create customer dissatisfaction by making the system too twitchy,” says Brannon, at AAA. Tesla drivers, for example, have proven very tolerant of “beta testing” and quirks. Your average driver, maybe less so.

Based on its own research, IIHS has pushed automakers to install AEB systems able to operate at faster speeds on their cars. Kidd says IIHS research suggests there have been no systemic, industry-wide issues with safety and automatic emergency braking. Fewer and fewer drivers seem to be turning off their AEB systems out of annoyance. (The new rules make it so drivers can’t turn them off.) But US regulators have investigated a handful of automakers, including General Motors and Honda, for automatic emergency braking issues that have reportedly injured more than 100 people, though automakers have reportedly fixed the issue.

New complexities

Getting cars to fast-brake at even higher speeds will require a series of tech advances, experts say. AEB works by bringing in data from sensors. That information is then turned over to automakers’ custom-tuned classification systems, which are trained to recognize certain situations and road users—that’s a stopped car in the middle of the road up ahead or there’s a person walking across the road up there—and intervene.

So to get AEB to work in higher-speed situations, the tech will have to “see” further down the road. Most of today’s new cars come loaded up with sensors, including cameras and radar, which can collect vital data. But the auto industry trade group argues that the Feds have underestimated the amount of new hardware—including, possibly, more expensive lidar units—that will have to be added to cars.

Brake-makers will have to tinker with components to allow quicker stops, which will require the pressurized fluid that moves through a brake’s hydraulic lines to go even faster. Allowing cars to detect hazards at further distances could require different types of hardware, including sometimes-expensive sensors. “Some vehicles might just need a software update, and some might not have the right sensor suite,” says Bhavana Chakraborty, an engineering director at Bosch, an automotive supplier that builds safety systems. Those without the right hardware will need updates “across the board,” she says, to get to the levels of safety demanded by the federal government.
