In addition to the displays, the vehicle includes dual-zone climate control, a six-speaker Harman Kardon sound system, multiple charging points, and a cooled glove box.

The XUV 3XO has six airbags, three-point seatbelts, and an electronic stability control system.

The Mahindra XUV 3XO offers a range of engine options and the flexibility to choose between two gearbox configurations. The 1.2-litre turbo petrol engine delivers 110 bhp of power and 200 Nm of torque, while the 1.2-litre TGDi petrol unit makes 128.7 bhp with 230 Nm of torque. The diesel variant is capable of 115 bhp and 300 Nm of peak torque. All three engine options can be paired with either a six-speed manual or a six-speed torque converter automatic transmission.

The XUV 3XO introduces significant enhancements to the interior over that of its predecessor, including new features and an elevated level of comfort. The front seats are positioned higher, providing better visibility through the windshield. The cabin is further treated with leatherette upholstery and the dashboard features soft-touch panels. 

In contrast to the cramped rear seats in the XUV300, the 3XO offers a more spacious second-row. The interior provides ample headroom, legroom, and shoulder space, and the flat floor allows comfortable seating in the middle. The XUV 3XO is further fitted with a panoramic sunroof that Mahindra claims to be the largest in the segment.
