It may come as a surprise this morning to hear that two struggling automotive conglomerates – Stellantis and Jaguar Land Rover – are eager to link up their product development efforts, specifically in the US. The two automakers announced today they have signed a non-binding memorandum of understanding to collaborate and "create synergies across product and technology development, leveraging the companies' complementary strengths."Jaguar Those strengths are not readily apparent right now, as JLR reported an after-tax loss of $325 million for the last fiscal year, which is chump change compared to the $26 billion net loss for Stellantis in 2025.Can these two automakers help each other out of the trough? At first glance, JLR could benefit from this arrangement more immediately than Stellantis. JLR has no vehicle assembly plants in the US, and each imported Jaguar or Land Rover face tariffs of at least 10%, or 25% in the case of the Land Rover Defender built in Slovakia.Stellantis Excess Capacity That JLR Could Use Meanwhile, Stellantis has several manufacturing plants with excess capacity in Michigan and Ohio that might be useful for building Land Rover SUVs and mitigating current supply-chain headwinds. The Jaguar brand has essentially purged its US portfolio, so it's not likely in need of manufacturing capacity as it prepares to reveal the production version later this year of the Type 01 four-door luxury GT, which will be built in the UK.Beyond pulling some revenue from Land Rover for potentially handling contract assembly in the US, it's difficult to see how Stellantis benefits from a partnership with JLR, which mainly has a retail and marketing presence in the US. Perhaps Stellantis wants access to JLR technology hub in Portland, Oregon, for engineering, UX design, connected car features and autonomous driving research.“By working with partners to explore synergies in areas such as product and technology development, we can create meaningful benefits for both sides while remaining focused on delivering the products and experiences our customers love.”–Antonio Filosa, Stellantis CEO Stellantis Doesn't Need 2 More Brands Land RoverOr, is this the first step toward Stellantis taking control of JLR from Tata Motors? The India-based industrial conglomerate finalized its acquisition of the iconic British brands from Ford in 2008. That seems unlikely, as Stellantis already has too many automotive brands (14), including Alfa Romeo and Maserati. They might compete with Jaguar, and Jeep certainly aligns with Land Rover.JLR CEO PB Balaji said the collaboration will help unlock new opportunities for JLR, which has also been coping with the aftermath of a devastating cyberattack and rising warranty costs. "Working with Stellantis allows us to explore complementary capabilities in product and technology development that support our long‑term growth plans for the US market,” Balaji said.When will we see the fruits of this collaboration in production cars? With the ink still wet on the documents, it's safe to assume a year or more will pass before anything notable reaches new car buyers, if ever.
