Suzuki is ending joint development projects with GM for hybrid and fuel-cell technology.
The move follows Suzuki's tie-in with Volkswagen AG, which was announced last month. Consequently, VW is now Suzuki's largest shareholder, with a 19.9 per cent stake in the company.
"Suzuki is in a comprehensive alliance with Volkswagen. In every field including hybrid, diesel and electric cars, we will carry out joint development with them, or we will learn from them," Osamu Suzuki, chairman and chief executive, told Reuters.
He also said Suzuki plans to procure diesel engines from Volkswagen and would review its ties with PSA Peugeot Citroen and Renault, which currently supply diesel engines to Suzuki.
