another visit to hyundai casa ... here's what i got from the sales guy:

1. the car was tested at speed around 80 kph hi-way driving and resulted in 38.7 km/li

2. owners report 28 km/li combined hi-way/city (provincial roads) driving
***********

i notice they don't display the 38.7 km/li poster anymore ... but 28 km/li real world fuel economy is still impressive
