The “modern ERGO seats,” which gained German civic group Aktion Gesunder Rucken’s accreditation for their comfort and back protection, embraced the back and shoulders perfectly. The moment I leaned back, it naturally hugged me so I wasn’t sure I’d ever want to get up, perfectly in line with the carmaker’s description of the “First Class VIP Seat.”

The smooth acceleration was thanks to Hyundai’s signature Lambda engine --the 3.3 turbo charger and the 5.0 engines -- which also helped comfort in the back even when driving at speeds in excess of 240 kilometers per hour. On the pebbly road, winding road or cemented, cracked roads, the 1-centimeter thick fender in the seat managed to reduce shock delivered to the body. 

Hyundai also took extreme care in ensuring silence.

“We have made a vacuum in between the layers of the wheels so that it could reduce the noise of the shock to the shock absorber. This has helped us decrease the noise by three decibels. The three-layer sealing weather strips on the doors and the noise-blocking glass used for the windows have managed to contain the noise to a minimum level,” a Hyundai Motor America spokesman said. 

“I say the G90 steering is a bit more stable than the Lexus 460L (which is considered a market competitor pricewise). That may have helped reduce noise and raise the comfort,” Michael Csakan, an engineer at the proving ground, said.

The G90 will be rolled out in May 2016, and Hyundai said considering shipping and other logistics, sales will start in the second half of the year.
