Well, again, 2017/18 XC90s have all features listed in this article except the STEERING SUPPORT FOR EMERGENCY BRAKING, but that feature is not available for XC60 either.
Steering support means that the car will steer itself during emergency braking to avoid the obstacle. This is not available in any Volvo yet, probably in the future.
Yes, the car can steer itself when following lanes or when parking, but will not steer itself during emergency braking, it will just stop.
If you see it listed currently please provide the link, but I am pretty sure is not there, I just tried.
No. This is now. It is no the site as a feature of the current model.
