In a joint announcement, the Honda Motor Company and General Motors said they have agreed to work together on new-generation electric vehicles. The new Honda EVs will be designed by the Japanese automaker inside and out but will use the new global EV platform of General Motors as well as the newly announced battery system that GM has dubbed Ultium.

Unusually though, the new Honda vehicles will be built at GM factories in North America, and are expected to start sales for the 2024 model year, meaning the launch will be sometime in 2023, or even earlier.

"This collaboration will put together the strength of both companies, while combined scale and manufacturing efficiencies will ultimately provide greater value to customers," said Rick Schostek, executive vice president of American Honda Motor Co., Inc. "This expanded partnership will unlock economies of scale to accelerate our electrification roadmap and advance our industry-leading efforts to reduce greenhouse gas emissions."

GM and Honda have worked together on many occasions before when it came to vehicles that crossed over between brands. More recently, Honda and GM established a relationship with regards to battery modules in 2018, as well as fuel cells for the Cruise Origin; Honda, after all, is the leading automaker in the field of fuel cell technology.

Beyond the new Honda EVs to be built in collaboration with GM, the two automakers are looking at other avenues to work together on. According to Schostek, the two companies "are in discussions with one another regarding the possibility of further extending our partnership."

The announcement said that while the new Honda vehicles will be designed by Honda, the engineering of the platform will in line with the unique driving character expected of the brand. Interestingly enough, the new models -which will be made by Honda- will have GM's OnStar support integrated with the HondaLink system, along with GM's hands-free driver-assist technology.
