Tata Motors Passenger Vehicles and Stellantis have formalised an agreement to expand their long-standing partnership, paving the way for a new Jeep SUV based on the Tata Sierra's ARGOS architecture. The upcoming model is expected to be developed and manufactured in India, with a planned launch timeline in the first half of 2028.
The project marks a deeper level of cooperation between the two automotive groups. Their partnership, which has primarily focused on manufacturing and powertrain-related activities, is now expanding into vehicle platforms and product technology.
The upcoming SUV cars is internally codenamed J1J at Stellantis. It is expected to be offered with internal combustion engine (ICE) and electric powertrain options, although final specifications and the production name have not yet been announced.
The new Jeep SUV is expected to use Tata Motors' ARGOS platform, which underpins the Tata Sierra. ARGOS stands for All-Terrain Ready, Omni-Energy and Geometry Scalable. The modular architecture has been designed to support different vehicle sizes and multiple powertrain types.
The platform's flexibility is particularly relevant for Jeep because the brand requires suitable hardware and engineering to support its SUV-focused positioning. The architecture is compatible with all-wheel-drive applications and electrified powertrains, providing a foundation for a model intended for more than one market.
Although the upcoming Jeep will share its underlying architecture with the Sierra, it is not expected to be a rebadged version of the Tata SUV cars. Jeep is expected to develop its own exterior design, body structure, cabin layout and equipment package to give the vehicle a distinct identity.
According to the report, the new Jeep SUV is expected to receive both petrol-powered and fully electric versions. The programme is also expected to draw on powertrain technology associated with the Sierra, although the final engine and battery specifications remain unconfirmed.
The availability of different powertrain options could help Stellantis address markets with varying fuel preferences, emissions regulations and electric-vehicle adoption rates.
A range-extender electric vehicle configuration is also being explored, but a production decision has not been finalised. Buyers should therefore treat this as an option under evaluation rather than a confirmed variant.
Jeep-specific suspension tuning, off-road equipment and final drivetrain combinations have not been officially detailed.
The new Jeep SUV is expected to be manufactured at the Fiat India Automobiles facility in Ranjangaon, Maharashtra, which operates through the Tata-Stellantis joint venture.
The facility already plays an important role in the partnership's manufacturing operations. Production of the new model would extend that relationship beyond existing manufacturing arrangements and into the use of Tata-developed vehicle architecture.
The factory is expected to undergo preparations and adaptations for the new programme ahead of the planned production timeline. However, the final production schedule and manufacturing specifications remain subject to confirmation.
The upcoming Jeep SUV is being developed with international markets in mind, rather than solely for Indian customers. The model is expected to be produced in India and exported to overseas markets after its launch.
A left-hand-drive version is also being developed for markets where vehicles are driven on the right side of the road. This could help the new SUV reach a wider customer base beyond India, subject to market-specific approvals and final export plans.
The project forms part of Stellantis' wider strategy of using regional partnerships and local manufacturing capabilities to develop vehicles for global markets. The company has previously outlined plans for India-developed products to support its international portfolio.
The specific countries that will receive the new Jeep SUV have not yet been confirmed.
For Tata Motors, the arrangement could create additional opportunities to use its vehicle architecture beyond its own product range. Licensing the ARGOS platform to Stellantis may help spread development costs across more vehicles and create a new source of platform-related revenue.
The partnership could also benefit component suppliers by increasing demand for compatible parts. Where common components can be used, the companies may be able to improve production scale and purchasing efficiency.
At the same time, Jeep-specific styling, engineering requirements and safety regulations will require additional development work. Sharing an architecture does not mean the two SUVs will have identical bodies, interiors or driving characteristics.
The new SUV could become an important addition to Jeep's future product portfolio. The brand operates in a competitive Indian market, where buyers increasingly expect a combination of modern technology, efficient powertrains, premium interiors and competitive pricing.
Using a locally developed platform could help Stellantis control development and manufacturing costs while creating a vehicle tailored to Jeep's requirements.
The potential availability of petrol and electric versions may also allow Jeep to address different customer needs. However, pricing, equipment levels, powertrain details and the model's positioning against existing SUVs are yet to be announced.
The final product will need to retain Jeep's distinctive design and driving characteristics while making effective use of the shared architecture.
Tata Motors and Stellantis have worked together for more than two decades through manufacturing and related automotive operations. The latest agreement represents a broader collaboration that extends into vehicle development and platform technology.
For Tata Motors, the project offers a potential way to extend the use of the Sierra's architecture. For Stellantis, it provides access to an India-developed platform and local manufacturing capabilities for a new Jeep product aimed at international markets.
With the first SUV expected in the first half of 2028, more information about the production design, powertrains, features and export destinations is likely to emerge as development progresses.
