Noise cancelling technology has been around for a while and is employed by nearly every automaker. Whether it's dense foam insulation, thick carpets, technological innovations, or recommending a certain tire compound, there are many ways automakers work to keep road and engine noise from permeating the cabin.

Hyundai is taking those traditional methods of sound-blocking even further with the world's first Road Noise Active Noise Control (RANC) system, which the company says "dramatically reduces" cabin noise.

RANC is the next step in active noise control technology and works by emitting sound waves that have been inverted to incoming noise. Think of it like two magnets repelling each other.

Previously, active noise control technology only allowed predicted noises to be able to be muted.

"RANC is a remarkable technology which takes existing noise, vibration, and harshness (NVH) technology to the next level," said Gangdeok Lee, a Research Fellow of NVH Research Lab, "We will continue to take the leading position of NVH highest level of quietness to customers."

The new RANC technology, which took six years to develop, analyzes road noise in real time, using an acceleration sensor, and calculates the vibration from the road to the car. A computer analyzes the results and the system optimizes the signal in less than 0.002 seconds, adjusting accordingly.

RANC is able to calculate the sound independently for the driver, passenger, and rear seats.

Hyundai testing revealed that RANC is able to reduce in-cabin noise by 3dB, roughly half of what is currently experienced in Hyundai vehicles.

This technology has further reaching implications. Because Hyundai will not have to rely on heavy, dense foams and carpet to help with cabin noise, they are able to lessen the amount of or remove those elements from vehicles, allowing for more passenger space and less weight. In turn, this could make vehicles more fuel efficient.

The system will be mass produced by Harman.

Hyundai Motor Group has completed domestic and American patent applications for the location of sensors and signal selection method, the core technology of RANC.

The technology will begin to be applied to an upcoming Genesis model.

Lexus Teammate advanced driver assist tech debuting on 2022 LS 500h

New Lexus Teammate driver assistance technology will debut on the 2022 Lexus LS 500h later this year. Its availability is constrained to all-wheel drive models.

The technology was developed based on the Mobility Teammate Concept. This automated driving concept is unique to Toyota sough to enhance communication between drivers and cars, "enabling them to reach out to each other for mutual assistance". The concept sees cars and humans interacting and partnering rather than having automation take over for drivers. This approach allows drivers to enjoy the experience of driving but allowing the vehicle to take over some functions of driver's duties at times. In this way, the tech works as both guardian and chauffeur.

On the 2022 Lexus 500h, Lexus Teammate will offer two functions: Advanced Drive and Advanced Park.

Advanced Drive is design to "accurately detect driving conditions to plan and execute acceleration, braking, and steering commands to maintain the vehicle within the lane, follow other vehicles, change lanes, navigate certain interchanges and traffic jams and overtake slower vehicles." It's a Level 2 functionality that "allows for driving on limited-access highways with partial hands-free, eyes-on-the-road operation".

This description makes it sound a lot like the suite of lane keeping, lane centering, and adaptive cruise control technology that Hyundai offers rather than true Level 3 technology that General Motors's Super Cruise delivers.

Advanced Park operates similar to how the Genesis GV80's hands-free parking assist technology works. The Lexus tech automatically controls steering, acceleration, braking, and gear changes with parallel parking or backing into a parking space. It uses a combination of 360-degree sensing technologies and a bird's eye view display to perform the task while allowing the driver to monitor progress.

"We are very proud of Lexus Teammate, which is the culmination of five years of close collaboration between our technical centers in Japan and the US. We conducted simultaneous development and rigorous testing in both markets with the goal of achieving industry-leading advanced driver assistance functionality," says Derek Caveney, executive engineer at Toyota Motor North America's Integrated Vehicle Systems team.

Hyundai gives hints about what to expect from Santa Cruz truck in new video

The Hyundai Santa Cruz will debut next week but ahead of that, the design department is giving a closer look at the truck in a new video.

We'll see the Hyundai Santa Cruz in full for the first time when it debuts on April 15 but ahead of time, Hyundai is setting the stage for expectations with the model. To help with that, the company released a video today featuring the truck's design manager discussing the inspiration for the utility vehicle.

The quick one-minute video is hosted by Brad Arnold, design manager at Hyundai North America. The Southern California native is the leader of the team that created the Santa Cruz, a project that began years ago. He's joined in the video by Senon Franco, the lead designer at Hyundai North America.

As Arnold explains in the video, the design of the Santa Cruz started with a simple premise: "this is not a typical truck". Based on how Arnold describes the capabilities of the truck, that sounds true. It is meant to "thrive in dense urban environments and the open outdoors". One could argue that no full-size truck on the market today does that. Neither do most of the midsize models, though their sizing is better for that landscape.

Arnold says that the Santa Cruz is "small in size", a call that serves to remind viewers that the Santa Cruz isn't a big truck. It's more similar in size to the forthcoming Ford Maverick, a small truck that slots below the Ranger in Ford's lineup.

However, the company isn't even calling it a truck. The new model is being referred to as the Santa Cruz Sport Adventure Vehicle. This sounds a lot like how Kia is referring to the new generation of its Carnival minivan as a multi-purpose vehicle (MPV).

Arnold says that the design is meant to make the Santa Cruz not look like a truck. Rather, it's supposed to look "like a Santa Cruz". Part of that includes the front end, which looks like a carryover from the fascia of the 2022 Hyundai Tucson.

Among the other secrets Hyundai is giving away ahead of the product's reveal is that there will be more than one "efficient" powertrain, a flexible bed, "cutting-edge" connectivity, and all-wheel drive.
