DETROIT — Jeep maker Stellantis

is leaning on technologies from automotive suppliers for its newest hybrid SUVs as the market for more fuel-efficient vehicles is expected to continue growing, CNBC has learned.

The trans-Atlantic automaker’s first-ever Jeep hybrid SUV for North America, its recently launched Cherokee, features a system from a Toyota-backed company called Blue Nexus, while its upcoming extended-range electric vehicles, or EREVs, are utilizing major technologies from Bosch, the world’s largest automotive supplier.

It’s not uncommon for automakers to use components from suppliers, but it’s less common for key systems or technologies, especially ones pioneered by a competitor like Toyota.
