The latest investment in US ride-hailer Lyft will send a fleet of luxury vehicles into the market – and they may one day be smart enough to pick up passengers on their own.

Carmaker Jaguar Land Rover on Monday announced a $33 million investment in Lyft and pledged to supply a fleet of vehicles as it conducts research on self-driving cars. Jaguar Land Rover announced the move through InMotion, its mobility-oriented investment fund.

InMotion says the move will be a boon to Lyft as it eyes expansion and upgrades for the self-driving technology it is testing. The deal will also help the mobility group test its own autonomous technology, InMotion said. In addition, Lyft drivers will eventually be able to rent Jaguar or Land Rover vehicles. 

Jaguar Land Rover joins a slew of carmakers and tech companies to have invested in the San Francisco-based company over the past year. Last year, General Motors announced a $662 million investment in Lyft in hopes of launching an eventual self-driving shared ride service. Lyft has also partnered with Waymo, the autonomous vehicle subset of Google's parent company, and nuTonomy, a self-driving start-up, in its self-driving vehicle research.

"Personal mobility and smart transportation is evolving and this new collaborative venture will provide a real-world platform helping us develop our connected and autonomous services," Sebastian Peck, managing director of InMotion, said in a statement.

A Lyft spokesman said exact details on the deal were still "being worked out", including how many vehicles Jaguar Land Rover will supply, what models will be tested and when and where they will be deployed. The fleet agreement is separate from the $33 million investment, Lyft said.

"We want Lyft to be the OS for autonomous vehicles – the place where consumers come to access the best autonomous vehicles from a variety of partners," the spokesman said.
