NHTSA looks to add new advanced driver assistance tech to testing regimen

The U.S. Department of Transportation's National Highway Traffic Safety Administration (NHTSA) has made public a list of proposed upgrades to the New Car Assessment Program (NCAP). NCAP testing addresses the crashworthiness of a vehicle as well as the vehicle's headlight functionality. These new proposed measures go even further, putting driver assistance and safety technology to the test.

Automakers often strive to achieve the highest score possible in NCAP testing, wearing their five-start safety ratings and Top Pick designations as badges of honor in marketing campaigns.

"Thanks in part to NCAP, new vehicles today are much safer than a generation ago," said NHTSA Deputy Administrator James Owens. "Even so, there are still too many fatalities and serious injuries in crashes every year, so it is critical that vehicles keep getting safer in the future, and a modernized NCAP will better enable American families to select vehicles with the safety features they want."

The immediate planned update to NCAP testing includes four advanced driver assistance systems (ADAS): lane keeping support, pedestrian automatic emergency braking, blind spot warning, and blind spot intervention. Engineers have designed these four specific technologies to mitigate high-frequency and high-risk crash types.

NHTSA is currently seeking public input on how best to develop a rating system for ADAS technologies.

"These upgrades will make NCAP more dynamic," Deputy Administrator Owens said. "American car buyers want safety, and NHTSA wants to empower them with comparative safety information about vehicles in the market. This information creates powerful market-based incentives for automakers to invest in advanced safety technologies that will save lives and prevent injuries."

The NHTSA began testing vehicles in 1978. The first tests examined frontal impact protection and used data from crash test dummies. The five-star safety rating system was established in 1993 and have been steadily increasing the scope of the testing over the last two decades.

The Ascent got updated styling and fresh tech.

Subaru

Subaru's lineup is full of useful, adventure-ready vehicles, but most are not accommodating for full-size families. The Ascent solved that issue for the automaker a few years ago, and has been a popular family option since. It got a mild update for 2023 with a facelift and new tech. The Ascent comes in five trims: Base, Premium, Onyx Edition, Limited, and Touring. It's expected to go on sale in fall 2022.

The Subaru comes with a new front fascia design that adds a new grille and aggressive styling up front. Lower air ducts help improve aerodynamics, and in higher trims the components come with chrome trim. The SUV's C-shaped taillights got a refresh as well, and now feature a sharper shape to better match the vehicle's overall styling.

The Ascent's powertrain remains in place, which is a turbocharged 2.54-liter four-cylinder making 260 horsepower. It sends power to all four wheels through a continuously variable transmission that offers a simulated eight-speed manual shifting mode. Subaru's X-Mode driving mode comes standard, which alters throttle response and other vehicle behavior to maintain traction in slippery conditions. Torque vectoring, which allows the vehicle to shift torque between wheels that need it most, also comes standard.

A new Onyx Edition trim joins the Ascent line for 2022. It brings a standard 11.6-inch touchscreen with navigation, a Harman Kardon sound system, power seats, and a panoramic sunroof. The base Ascent comes with features such as 18-inch wheels, USB inputs, tri-zone automatic climate controls, three rows of seating, and a whopping 19 cupholders. Subaru also offers an optional Cabin Connect system, which allows the driver or front passenger to communicate to people behind them through the stereo using a front-cabin-mounted microphone.

Subaru EyeSight safety equipment comes standard with every Ascent. The system is improved for 2023 with a wider field of vision and new software. A new wide-angle camera joins EyeSight's existing two-camera setup to provide better pedestrian and cyclist detection when approaching intersections. Blind spot monitoring, rear cross-traffic alerts, and lane change assist are available.

The IIHS may increase the speeds it uses to test advanced driver aids.

Insurance Institute for Highway Safety

The Insurance Institute for Highway Safety (IIHS) recently announced that it is considering changing the speeds it uses to test vehicle-to-vehicle front crash prevention systems. The agency currently tests the systems at 12 and 25 mph, but says that the speeds don't accurately represent the types of crashes the safety tech is meant to prevent.

Automatic emergency braking (AEB) is designed to notify of a possible collision and help respond with automatic application of braking. Just like a human using the brake pedal, it can stop the car, but higher speeds make it difficult to stop in time. The new tests would be conducted at 35 to 45 mph, which is the range where a large number of rear-end crashes occur. As Automotive News noted, an IIHS study showed 43 percent of rear-end crashes occur at speeds of 45 mph or less, so it's important to have a test that shows how well the tech performs at those levels.

A whopping 85 percent of 2022 vehicles earned a "Superior" rating in the current testing regime, so the IIHS will remove it from 2023 testing and Top Safety Pick award evaluations. Their view is that, since the majority of vehicles meet the criteria, it's no longer an accurate way of evaluating performance. In its place, the agency introduced a night test for automatic emergency braking systems that will begin next year.
