The desi SUV comes packed with a long list of features and also comes equipped with the Advanced Driver Assistance Systems (ADAS). This system includes semi-autonomous driving features such as adaptive cruise control, lane keep assist, auto emergency braking and many more. The 182 bhp, 2.2-litre turbocharged diesel engine comes with a choice of both 6-speed manual and automatic gearboxes. Apart from that, the 6-speed automatic gearbox is well-suited for both urban and highway duties.
