We have had the Sport variant here for a while, and the following differences:
- Tires 225/45R18 vs 205/60R16
- Aluminum pedals
- Tinted windows
- Separate ventilation for rear passengers.
- Leather seats.
- Driver seat memory settings
- Some cosmetic differences on the exterior as seen in pictures.
Things like HID, fog lights and heated seats are standard over here on all models.
But what's going to be classified as Sport in the US may be different.
