The New Toyota Tundra Engine?

With the confirmation that Toyota is building a new Tundra to compete with the Ford Raptor and Ram RHO. I had the idea of what if they put in a tuned down engine from the Toyota GR GT in the Tundra? For those who don't know what the Toyota GR GT is click here. But here are also the motor specs. Engine Type: 4.0L Twin-Turbo V8 (3,998 cc) with Hybrid Assist Power Ouput: 640HP Torque: 627FT-LB Configuration: 90-degree V8, Front-Midship Induction: Hot-V (turbos located in the valley Lubrication: Dry-Sump Transmission: 8-Speed Automatic (Wet-Start Clutch) Hybrid System: Single electric motor Now I don't know about you but that sounds pretty awesome. But, this is not practical for a production consumer truck. Here is what should change. 1. Hot-v design may not be best for longevity of the turbos or motor. 2. Dry - Sump oiling system may not be the best for consumer use 3. Swap out the 8 speed transmission for the 10 speed already in use. I feel like there is great opportunity here for this motor. BRING BACK THE V8!

This truck is massive! Coming from a 5th Gen 4Runner and 2nd Gen Tacoma, the Tundra has an insane amount of space.

I feel like my legs have a good three miles of breathing room back here! Haha

So much room for activities!! Just thinking about all the boxes of mods I can fit back here before they get installed.

The SR5 Interior is surprisingly comparable to the 3rd Gen Tacoma TRD Offroad Interior.

The Tundra Backseat is HUGE!
