Q. What is difference in W8 and W8 Option - XUV 300?

Both the Variants has Feature differences, Additional Features available in W8 (O) has 7 Airbags, including knee and side airbags (best-in-class), Leatherette interiors ,Auto-dimming IRVM, TPMS(tyre pressure monitoring system) ,Front parking sensors (first-in-class),17-inch diamond cut alloy wheels, Sunroof,Dual-tone roof rails.

Actually w4 and w6 both are same now except sunroof. Before they were providing touch screen infontment system in w6 but now it is also removed hence now both models are same except sunroof. Now value for money model is w8 variant if you do not want Sunroof else both variants are most of same.

W8 and W8 option is almost the same, except it has extra features like the sunroof, alloy wheels, front parking sensors etc. However it's worth putting extra cash for w8 option
