After previously announcing a partnership surrounding their electric vehicles, General Motors and Honda have deepened their alliance by announcing that they will do-develop and share platforms and engines.

Under the proposed alliance, Honda and GM would collaborate on a variety of segments in North America (no word if the collaboration will extend to other markets). Co-development planning discussions will begin immediately, with engineering work beginning in early 2021.

An alliance in North America between Honda and GM would help the companies leverage the best technologies and general cost efficiencies thanks to shared vehicle platform and engines (both internal combustion and electrified), joint purchasing, potential manufacturing efficiencies, and other collaboration efforts. This would enable both GM and Honda to make greater investments in advanced and next-generation technologies.

The companies also plan to share R&D and engineering costs for select future co-developed vehicle and engines. This would create substantial efficiencies and free up capital, enabling both companies to meet the increasing requirements to invest in various future mobility trends and additional growth opportunities for each company’s distinct brands.

All facets of the alliance will be governed by a joint committee, comprising senior executives from both companies.
