From the Floor of CES: Supernal’s Newest Passenger eVTOL

Supernal Unveils SA-2 at CES – “Kinetic Purism”

By: Dawn Zoldi

CES®, the most powerful tech event in the world, provides the world a stage for the breakthrough technologies and global innovators that will change the world. Yesterday, to kick off the first day of this unparalleled tradeshow, Supernal, a part of the Hyundai Motor Group, unveiled a physical prototype of its latest release, the SA-2 electric vertical takeoff and landing (eVTOL) aircraft. The company hopes to reshape how people see mobility and to redefine transportation with this stunning new vehicle.

Jaiwon Shin, President of Hyundai and CEO of Supernal, a seasoned engineer with over 30 years of experience leading NASA’s aeronautical research and development, explained the problems Supernal is trying to solve with its SA-2 aircraft. “Urban Areas are denser, roads more congested and the planet in desperate need of more sustainable solutions,” he said. “A 20 mile urban journey by car can take an hour in traffic. With advanced air mobility (AAM), the same journey can take just minutes,” he continued.

The hope is that commuters will routinely choose to fly safely and comfortably at 1500 feet AGL in a comfortable and quiet cabin, enjoying panoramic views of the city below, in Supernal’s SA-2 by 2028.

This reveal follows the company’s 2022 CES release of their vision for an AAM vehicle, the SA-1 eVTOL concept. Supernal engineers evolved that original concept into the current design to address the ever-expanding mobility needs of today. To get to this point, the design team narrowed down over 100 different vehicle shapes during its creative ideation phase to just one.

In describing his aircraft, Shin noted, “This is what happens when auto meets aero.”

This initially-piloted electric battery-powered, v-tailed aircraft can accommodate up to 4 passengers, in modular seats which can be reconfigured or even removed in between flight legs. It will be able to cruise at 120 mph at 1500 feet AGL across average trips of 25 to 40 miles. It has 8 rotors, 4 in front and 4 in back, which work together at all times and in all phases of flight. Importantly, during flight, they will remain as quiet as a modern dishwasher, registering only 45 decibels during cruise and 65 decibels during take off and landing.

CTO Ben Diachun elaborated that his team harnessed the full advantage of electric powertrain advancements to define this next gen aircraft. “Getting to this point took a lot of planning, studying and refinement.” That process, he explained, centered around 4 key principles: safety, sustainability, scalability and consumer-focus.

From a safety standpoint, “AAM must be safe with no compromises,” according to Diachun. His team iterated that primary focus on the safety of passengers and the public into a robust airframe architecture with redundant systems. They partnered with top tier aviation companies. They put the aircraft through rigorous design assurance testing. As a result, the SA-2 is equipped to fly in all weather, during both day and night. The company also continues working with government regulators on airspace management policy in furtherance of its safety mission.

This kind of forward-thinking ties into Supernal’s third goal, scalability. The aircraft had to be cost effective while maintaining the highest quality. “We will have to deliver 10s of 1000s of these to meet demands,” according to Diachun. “We will do this by leveraging Hyundai’s mass production capability,” he said. “This will bring down the barrier to entry for operators and everyone, who will benefit from this tech.”

Finally, the design had to be customer-centric. Supernal aims to bring the best in-car passenger experience to the sky. To make the inside of the vehicle as elegant as the vehicle behind it, Chief Creative Officer, Luc Donckerwolke, who has spent his entire career designing cars (including “Italian super sports cars”), closed the circle by purposely designing the aircraft’s interior around the passenger-user experience, from ergonomics, to performance and aesthetics. Donckerwolke describes the final outcome as “kinetic purism.”

Internally, the aircraft has 2 sections, a passenger cabin and flight deck, differentiated by different colors. The ergonomic seats were deliberately engineered to absorb vertical energy. Its storage areas contain all the modern conveniences in a premium cabin, such as cup and eyeglass holders. Supernal aims to win hearts and minds over to AAM through this level of human-centric design.

“We are moving AAM out of sci fi movies and into the real world,” Shin said in closing. “We are working to change the world of mobility for the progress of humanity.”

Keep an eye on the skies for Supernal’s SA-2 in the coming years, as they reach beyond and reach further to provide boundary-breaking aircraft to help create a future where the skies above us become the roads of tomorrow.
