[quote=ag4ever]The duramax in the GM trucks is an Isuzu joint venture. It might be that Toyota is positioning themselves to use such an engine in the new Tundra that is slated to compete with the domestic's 3/4 ton and larger trucks.

I would love to see Toyota release a jetta TDI killer, but I doubt that will happen anytime soon.[/QUOTE]

That would be the Prius. They are the same size and accomplish the same goal at about the same price level.

Now if Isuzu's diesel technology were to be put into a Corolla or Yaris or small pickup... that's additional business opportunities.
