Chatting with Wayne on the phone. New button on the steering wheel - labeled "Blue" - underneath the reset button. It seems to change the nature of the car (seems to do the same job as the Eco button). Changes shift points, softens the throttle, and tweaks other powertrain parameters. Wayne says Hyundai really got this right. For the first one out of the box, it is absolutely spot on. Wayne says the Sonata can go into EV mode even when climbing a hill as long as the SoC is high enough. The car continually rebuilds the SoC and keeps it high. When it gets to 7/8 charge, it goes to EV, even on uphill grades. You don't have to force it - it just does it. Excellent! Seems like they got the highway cruising portion of the powertrain control perfect. This is definitely a highway cruiser. Also, Bluetooth is excellent. Maybe not up to BMW/Lexus standards, but it's clear and great quality. When Wayne picked up the car at John Wayne airport in Santa Ana last night, the valet who retrieved the car said, Wayne also noted that the hybrid glides much better than the Sonata GLS, too. The hybrid-specific LRR tires and 0.25 drag coefficient do make a difference.
