Edmunds.com is reporting that Toyota is looking at the Cummins V8 diesel for the next Tundra. Cummins previously said they had enough capacity at their engine plant to supply Nissan (for the Titan pickup) and one more manufacturer.

This would be an interesting development, since Toyota makes a 4.5L V8 diesel of its own for use in the Land Cruiser 200 and Land Cruiser 78/79. The Toyota twin turbo 4.5L diesel produces about 480 ft lb of torque, or about 70 ft lb less than the 5.0L Cummins turbo V8 diesel. In addition to the power advantage, the Cummins V8 will be manufactured in Indiana. So it will be relatively easy to ship the engines to San Antonio, where the Tundra is made. The Toyota V8 diesel engines are made in Japan.
