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.

Trailering

GM shortens trailer stopping time with new, innovative eBoost technology

A new technology developed by General Motors may change the trailering experience as we know it, making it safer for everyone involved.

For some folks, towing a trailer is second nature. It's like riding a bicycle or going for a swim. But for a vast majority of others, towing can be intimidating, scary and even downright dangerous. No matter what category you fall into, truck makers have been working feverishly to come up with new and exciting technologies to make towing easier and safer for you.

One of the biggest challenges of towing, at least at speed, is the abrupt need to come to a stop. Whether it be someone pull out in front of you or the traffic light turned red sooner than you'd expect. Towing down a grade in high winds can create even more issues.

To help with towing and stopping, electronic trailer brake controllers are common on rigs that tow. They help control the trailer by apply the brakes in the trailer. Setting up a trailer brake control is often described as an art, not a science.

That's where new General Motors tech comes in. Using their electronic brake system from their heavy-duty pickup, the company has fitted it to a trailer for the purpose of improving braking. Their goal was to equip a trailer with the company's eBoost braking system and see how well they could stop with it.

Their goal was to take a 2020 Silverado HD without a trailer and see how far it took to stop. Then they attached a trailer with 9,000 pounds and set a target of stopping in the same distance. They were within three feet.

That means in a full-on, emergency stop scenario a truck towing a 9,000-pound trailer can stop as short as a truck without a trailer. Not to overwhelm you with hyperbole, but that is a game changer.

Why? There's no complicated setup of the trailer brake controller. The equipment already exists, and GM managed to do it with around $1,000 worth of hardware that's already available. It would require a trailer manufacturer to integrate it with their trailers, but the safety benefits are huge.

Unlike some aftermarket anti-lock braking systems, primarily from Bosch, this system communicates with the truck, and can even use electronic stability control to reduce trailer sway.

It's a prototype at this point. GM is hoping to find a trailer maker to help develop the technology. The marketing department is still figuring out all of the details, but in addition to offering it on a brand-new trailer, it might even be possible for certain dealerships or installers to add it to existing trailers after the fact.

While there is a truck war going on with how can tow and haul the most, the efforts that GM is making right now for improving towing safety, such as their invisible trailering system and this prototype trailer brake system, makes the roads safer for everyone – even if they don't drive a GM.

Everything you want to know about the 2020 Hyundai Venue

The Hyundai Venue is new to the U.S. for the 2020 model year.

If you thought it didn't get any smaller than the subcompact Hyundai Kona, you were wrong. Hyundai's new, smaller SUV, the 2020 Hyundai Venue, has made its way to the U.S. market. Here's a quick look at everything you need to know.

Hyundai developed the model to be budget-friendly.

Research indicated that people often pass up buying new cars because they are too expensive, but then they miss out on the latest safety and infotainment tech. Hyundai wanted to create a vehicle that would cost as much as a used car but have all new equipment.

The Venue comes in three trim levels.

Buyers get to choose between the base SE, SEL, or top-tier Denim model. All the models come with the same engine but the base model has a six-speed manual transmission as opposed to the Venue SEL and Denim's intelligent variable transmission. SEL and Denim models of the front-wheel drive SUV have three drive modes: normal, sport, and snow.

The Nissan Kicks isn't very quick. What is the engine like in the Venue?

The Venue is powered by a 1.6-liter four-cylinder. It's peppier than the Kicks but nothing too exciting. Still, you'll feel like you have plenty of power at speed.

Hyundai has loaded the Venue with a solid list of safety features.

Standard and available safety features include:

  • Forward Collision-Avoidance Assist (FCA) uses the car's front-facing camera to help detect an imminent collision and avoid impact or minimize damage by braking
  • Lane Keeping Assist (LKA) helps prevent accidental lane departure by sensing road markings automatically steering the car if necessary.
  • Blind-Spot Collision Warning (BCW) helps detect approaching vehicles that may be obscured from view during highway
  • Driver Attention Warning (DAW) system monitors a spectrum of driver-related characteristics to help detect driver fatigue or careless
  • Rear Collision Cross-Traffic Warning (RCCW) helps detect when a vehicle may have entered a car's rearward path providing a driver

It's supposed to cost as much as a used car. What's the MSRP?

Hyundai sells the Venue SE for $17,350. The SEL is $19,250 and the Venue Denim is $22,050. That MSRP does not include the destination charge. Remember, most dealers are willing to negotiate on prices.

So it's a cheap car. Does it look cheap inside?

The short answer is no. The Venue Denim has nicer appointments than many mid-grade trucks on the market that cost a fair amount more. The designer of the HVAC system controls should be proud that they're both easy to use and attractive while looking like little else currently on the market.

The seats are comfortable.

Most low-cost SUVs and cars have seats that aren't comfortable for any length of time. The Venue is the exception to this rule.

When does it go on sale.

The Hyundai Venue is currently for sale at dealerships nationwide.
