General Motors has told UK-based Torotrak that it will not be exercising its option for a production licence for Torotrak’s Infinitely Variable Transmission (IVT) technology.
According to Torotrak, the IVT demonstrator vehicles that GM have been reviewing over the last six months have successfully proved that the technology works, satisfied the technical and functional requirements, achieved the fuel economy targets for the project and exhibited excellent driveability.
However, ‘commercial considerations’ have led to GM’s decision not to undertake any further internal development work for the foreseeable future.
In a statement, Maurice Martin, chief executive of Torotrak, said that he believed that, increasingly, the delivery of new technology in the automotive industry was now in the hands of the Tier 1 suppliers who deliver new products and systems direct to the OEMs for incorporation into vehicles.
And, he added, the Torotrak strategy to build strong Tier 1 supplier partnerships was already in place and development was progressing well with Shell, Getrag, Koyo Seiko and Equos, the new product development division of Aisin AW, the world’s largest independent automatic transmission manufacturer.
