Overall
XUV 700 is a fantastic vehicle, which an entire family will love. Having driven Harrier, Innova & Fortuner in the past, I would say XUV is better than all of them in terms of power, space, comfort & refinement as an overall package. Yes, even the Fortuner (may be an unpopular opinion).
ADAS
I was of the opinion that ADAS would be useful on such a long highway drive. But, boy was I wrong.
Lane Keep Assist - just does not work on a 4-lane highway system where no one follows the lane discipline. It keeps beeping & correcting too often. Switched it off in the first 30 mins.
ACC - Cruise control works well for the most part. But when it detects a slow-moving vehicle up ahead, it applies brakes pretty hard. Making the ride uncomfortable.
Also, if the smart pilot assist is tick marked, the lane keeps assist automatically turning on during cruise control. I had to take a second stop to figure this out & disable it.
ACC needs to be disabled every time there are slow-moving vehicles in both lanes, otherwise, ACC applied hard brakes on detecting the vehicle up ahead.
Overall, a lot of juggleries are required to make ACC work. There were times when I just decided to drive without ACC, as I did not want to do all the jugglery.
ADAS features work well on expressways. Like Hyderabad ORR, on that road, I could switch on all features & relax a bit while driving.
