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.

All 2021 model year BMWs will come with a free year of SiriusXM  All-Access

BMW infotainment systems recently received a major upgrade.

All 2021 model year BMW automobiles will come standard with a free one-year SiriusXM All-Access subscription. The move is part of a larger deal that extends the relationship between BMW and SiriusXM through 2026.

The news comes just weeks after BMW divulged that a long list of its 2021 models will come with SiriusXM with 360L, an audio platform that combines satellite and streaming content delivery into the existing SiriusXM platform. SiriusXM with 360L made its debut in the redesigned 2019 Ram 1500 and after a year of exclusivity is moving into more vehicles throughout the market space.

BMW delivers their customers a premium experience every time out on the road. We're very proud that SiriusXM has been a popular feature of that in-vehicle experience dating back to the earliest days of satellite radio in 2002," said Rodney Pickett, SVP, Automotive Partnerships, for SiriusXM. "Today we are truly excited that our relationship continues to grow, as we announce that SiriusXM will be standard on all BMW Group vehicles, ensuring all of their customers can enjoy our premium programming content for many years to come."

Earlier this year, BMW announced five big updates to its infotainment system. You can find out more about that here.

BMW vehicles with SiriusXM with 360L will be able to receive software updates allowing customers to have accesss to the latest features without having to visit a dealership. The latest offering, Personalized Stations Powered by Pandora, will be part of a future software update. With Personalized Stations Powered by Pandora, drivers can create their own ad-free music stations based on the artist they are listening to, then give songs a thumbs up or thumbs down within the SiriusXM service, or even skip songs, to create their own personal channel that plays more of what they want.

BMW has offered SiriusXM in its vehicles since 2002. It is now standard across the BMW lineup.

"In-vehicle technology and entertainment have become as important to BMW drivers as the performance and handling of their new automobiles." said Monika D. Reimel, Head of BMW Aftersales Business Development. "BMW was one of the first manufacturers to offer SiriusXM in our automobiles and today we are excited to not only include SiriusXM as a standard feature in all of our 2021 models but also combine it with one of the longest initial subscription periods in the industry. This new agreement with SiriusXM offers immediate benefits to our enthusiastic customers."

Chevrolet's IMSA, NASCAR wins today are thanks to 3D-printed parts

Chase Elliott drives the No. 9 Chevrolet Camaro ZL1 1LE for Hendrick Motorsports. Antonio Garcia and Jordan Taylor drive Chevrolet Corvette C8.Rs in the IMSA WeatherTech SportsCar Championship. Their wins this weekend at Charlotte Motor Speedway were, at least in part, to the 3D printing technology that General Motors has been innovating over the last few years.

This season, the Corvette C8.R, IndyCar, NASCAR Camaro and Silverado race teams have accumulated more than 80,000 miles of competition in vehicles built with 3D-printed parts.

"Chevrolet has a long history of technology transfer between our motorsports and production teams, and this is a perfect example of our approach," said Jim Campbell, GM U.S. vice president of Performance and Motorsports. "GM's 3D-printing capability speeds up our learning cycles and, in turn, these racetrack experiences help our additive manufacturing team move one step closer to using 3D-printed parts in production vehicles."

Earlier this year, two Corvette race cars, both C8.Rs, debuted at the Rolex 24 at Daytona, each equipped with 75 3D-printed parts. Among those parts are an oil tank, tank inlet and cap, air conditioning driver cooling box and integrated hydration system, power steering pump bracket and headlight assemblies. Since then, the C8.Rs have accumulated nearly 8,000 miles of competition in seven races.

The Chevrolet IndyCar V6 exhaust system is 3D printed, which has allowed the company to eliminate failure points and increase design freedom while reducing costs. Chevrolet IndyCar engines have run over 60,000 miles since the season kicked off at Genesys 300 at Texas Motor Speedway in June.

The Silverado off-road race truck debuted at the Best in the Desert Method Race Wheels Laughlin Desert Classic in October 2019. The Silverado competes in the 1200 Stock class, which limits changes to suspension, underbody and installation of race-safety equipment. The truck's rear damper shield is made of carbon-fiber reinforced plastic protects the rear dampers. It's made in-house by General Motors. Since its debut, the Silverado race truck has accumulated 900 miles of competition in six races.

Chevrolet engineers have optimized the aerodynamic performance of their NASCAR model using full-scale wind-tunnel testing. Oover 500 3D-printed prototype parts were used in testing to develop the ZL1 1LE body, which is new for this year. The Camaro ZL1 1LE is equipped with a 3D-printed gear cooling duct, which has accumulated nearly 18,500 miles of competition in 27 races.

"By utilizing 3D-printed parts, Chevrolet Motorsports is demonstrating the many benefits of additive manufacturing, including manufacturing efficiencies, mass reduction, parts consolidation, creativity and cost savings," said Audley Brown, GM director, Materials Engineering, Additive Design and Manufacturing. "3D-printed parts can offer equal strength and durability to cast or milled components, which is critical for product development and design."
