The 2022 venza has the new gen three power split like the Camry,Prius and Corolla. It should have at least 170hp that’s plenty for a small SUV. You also should have the new Lion cells not the NiMH cells the former nickel cells last into the 200k miles range Lion cells have twice the cycle life of the older cells I would be surprised if you ever need to replace them do you keep cars into 300K+ miles? I have never owners a vehicle with more than 150k and those are commuter cars which get replaced at 5 years are or 150k whichever comes first.
There are at least two companies they rebuild Toyota hybrid packs the older Prius/Corolla packs can be had for $1200 and good for unlimited more miles if you buy the $700 extended warranty on them. Going from 28mpg to 50+ over 100,000 miles at $3+ per gallon is 22mpg better or 4500+ gallons saved at $3 per gallon that $13,000+ in fuel savings a $1900 pack is nothing compared to the reduced fuel costs laugh all the way to the bank my friend.
170hp is way to weak for me.
