Back in August, we reported that Toyota was possibly considering dropping in a diesel for its full-size Tundra pickup.

"The diesel engine is something that is on our evaluation list. Hybrid technology is something that is on our evaluation list. Either one of those alternatives could deliver some pretty good real world fuel economy,"said Rick LoFaso, Toyota's corporate manager for light trucks.

"I think Cummins would bring instant name recognition and obviously they are a leader in diesel engine technology. That is not the first time we would have a tie up with somebody else."

Well it seems Toyota has possibly made a decision and is turning to Cummins for help. Wards Auto reports that when the next-generation Tundra debuts in 2016, it will be available with a 5.0L turbodiesel V8 from Cummins. This is the same engine you'll find in the next-generation Titan. What's unclear is if the Tundra's version will have the same 300+ horsepower and 500+ pound-feet of torque as the Titan.

A source tells Wards that the Cummins engine is a possible placeholder as Toyota would use this to gauge customer reactions and see if it would be a good idea to restart their own diesel engine project. Back in 2007, the automaker was working on a diesel for the Tundra. However when the economy hit the fan in 2008, Toyota canned the project.

That would be interesting to see Nissan and Toyota use the same Cummins V8 diesel. More interesting to see if it is priced the same or not.

Interesting that the Tundra and Titan would get a V8 Diesel from Cummins while Dodge would only have an I-6. Also interesting that Nissan didn't tie up Cummins in an exclusive contract.

I thought Toyota has their own diesel technology in trucks overseas... maybe it isn't clean enough to sell here.

Very cool to find some of Toyota's older 80 series landcruisers that had diesels.

WOW, Some very cool sources off Toyota global web site for their diesels.

Interesting that Toyota does not have a particulate system for their own in house diesels. Fastest to market is to go with another vendor.

You can buy plenty of low mileage Toyota Diesels here.

This CHART shows Toyota's history of engine development and it shows in January 2007 they developed Toyota's First V8 Diesel. It was killed off after the global economic depression.

Toyota is dusting off this engine work, but it looks like from what I can find in reviewing their own documents on the web their fastest way to a Diesel Truck that meets US Regulations is a Cummins.

Interesting is the information that Cummins puts on their web site about Nissan and their new V8 5L diesel engine. They also have a V6 that they are shopping to all auto companies.
