I review the 2023 Toyota Tundra 3.5L IForce V6 twin turbo charged engine and test the real world fuel economy of this newer engine. the Tundra with the 3.4L Iforce engine is rated for a combined 20 mpg with a 18 mpg city rating and 23 mpg highway fuel economy rating. I compare the tundra with the Iforce engine to the notorious ford f150 3.5L ecoboost enigne to see which truck gets better real world fuel economy.

I hope everyone is doing well. I am certainly happy to upload this video and keep looking forward. but I was pretty excited to compare both of these engines in terms of fuel economy. both the tundra and the f150 have a 3.5L twin turbo charged V6 engine with dual over cams so in theory these engines should be very close in fuel economy and why I wanted to test out both truck.

we are running the same fuel economy loop with both trucks and doing it on the same day with the same driving conditions. so this should be a very fair real world fuel economy test.

I like to include both city, country and highway on my fuel economy run because I think that makes for a fair test between all engines in pick up truck.

as you guys saw I was surprised to see how well the ford f150 ecoboost engine did in comparison to the tundra Iforce engine. the ecoboost was much more fuel efficiency beating the tundra by over mpg which was a little shocking. I thought both these engines would be very close.

let me know why you guys think both these trucks got the fuel economy rating they did and why you think the ford was so much better!

Hope you liked the video!
