#IsuzuD-max

Update: Automotive News is reporting General Motors is now focusing “on the higher end of the market while the Japanese firm sticks to selling vehicles for everyday commercial purposes,” strongly hinting that GM is the one that broke off the collaboration. We’ve added detail below.

After announcing a new bromance with Mazda just over a week ago, Isuzu is calling it quits with its old beau General Motors.

(Or maybe GM caught Isuzu cheating behind its back. Who knows? The relationship dynamics at play between automakers are difficult to flesh out.)

Regardless, midsize trucks — badged as both Isuzus and Chevrolets — will be no more in the Land of Smiles. The duo, which has a truck plant each in Thailand, will decouple their R&D efforts as they move toward engineering new global midsize pickups.

Mazda is closing the door on its relationship with Ford and opting to partner with Isuzu for its next-generation pickup trucks.

The automaker announced a new agreement today that will see Isuzu build its next pickup model, bound for everywhere but North America. The two companies previously collaborated on a pickup solely for the Japanese market.

Uh oh. Here we go again. GM apparently wants a 10 percent stake in Isuzu to build commercial vehicles.
