Tata Motors’ OMEGA ARC uses a steel monocoque just like Land Rover’s D8 architecture. In fact, the carmaker highlights that key parameters such as wheelbase, opening width of the doors, front suspension architecture, seating and steering positions are identical to those of the D8 architecture. Hence, like the H5X concept from the Auto Expo, the Harrier too will have a whopping wheelbase of 2,740mm, same as the Discovery Sport. Compared to the Creta and the Compass, the Harrier’s wheelbase will be 150mm and 104mm more, respectively. Moreover, it will also be 40mm larger than the Mahindra XUV500’s.
