The new Toyota Tundra, going into production next month, may use a diesel built by a company other than Toyota. While the practice of going outside for a diesel engine is standard procedure elsewhere, Cummins building for Dodge and International building for Ford, Toyota has never gone outside their own walls for an engine.
With everyone demanding more diesels and the major U.S. light trucks scheduled to get diesels by 2010, you basically need a diesel to play in this game and Toyota doesn’t have one yet.
According to Toyota, they will probably develop one on their own or look to their commercial truck division to supply what they need, but in the mean time, someone else may get the call.
