The Nexon is based on the revised Tata X1 platform that debuted in 1998 with the Indica model and was adopted by other Indian brand cars.

It is characterized by two-tone paint (optional), dual halogen headlamps with projector low beams, and large chrome bands along the side.

[9][10] The engines are developed by Tata Motors and Austrian engineering company AVL: the petrol engine is the 1.2 L Revotron three-cylinder turbo 12-valve that delivers 81 kW (109 hp; 110 PS) and 170 N⋅m (125 lbf⋅ft) of maximum torque combined with a 6-speed manual or 6-speed automated manual transmission (AMT); the diesel engine is a 1.5 L Revotorq four-cylinder common rail 2-valve that delivers 81 kW (109 hp; 110 PS) and 260 N⋅m (192 lbf⋅ft) of maximum torque, also paired with a 6-speed manual or 6-speed Automated manual transmission(AMT).The Nexon has three special editions named Dark, Red Dark & Kaziranga.The vehicle has three driving modes City, Eco & Sports.

[16] Tata Motors launched the facelifted Nexon with feature additions and Bharat Stage 6-6-compliant engines in January 2020 and showcased to the general public at the Auto Expo 2020.

The Nexon facelift also received a standard 6 airbags, 10.25-inch full-digital instrument cluster, 360-degree camera, telematics, wireless charger, ventilated front seats, air purifier, electronic gear shifter, and others.

The new model will feature a redesigned exterior and interior, incorporating modern styling while maintaining core design elements.

The new Nexon will likely retain its petrol and CNG variants, but the future of the diesel engine is uncertain due to stricter emissions standards.

It is finished in Atlas Black paint and also has darkened cosmetic elements such as the leatherette upholstery, alloy wheels, and trim inserts.

For exterior design, the model gets a Grassland Beige paint with contrasting black elements such as the ORVMs and the roof.

On the interior, it has features like an electric sunroof, red colored leatherette upholstery, wireless charging pad, air purifier & ventilated front seats.

The Nexon EV (stylized as Nexon.ev) uses components from Tata Motors' electric vehicle technology brand Ziptron.

It receives a redesigned front fascia inspired by the Tata Curvv EV concept, a redesigned front end with a full-width LED light bar, and new features such as a larger 12.3-inch touchscreen, wireless charging pad, two fast-charging Type-C ports, and three drive modes that can be accessed from the center console.

Tata presented knee mapping data to have some penalties removed and made a seatbelt reminder for the front passenger a standard fitment for production from 7 December 2018.

They then funded a reassessment, including an evaluation of the added seatbelt reminder and a basic ECE Regulation 95 side impact test required for the maximum five-star rating for adult protection.

In December 2018, the Nexon for India became the first ever car model sold in the country to achieve the maximum five-star rating for adult protection in the tests (similar to Latin NCAP 2013).

[31] In 2024 the facelifted Nexon for India, featuring more standard safety equipment like electronic stability control, side and curtain airbags, i-Size compatibility, a three-point seatbelt in the rear centre seat and seatbelt reminders for all seats, was awarded 5 stars for both adult and child safety by Global NCAP, against their updated evaluation criteria (based on Latin NCAP 2016).
