I have be doing a lot of reading on this and other forums. Iwant to create a place where technical ininfomation could be accessed easily. What I am insterested in is what makes the V6 in the RAV4 is unique (both in power and fuel efficiency). I have seen posts that mention The electronic power steering system contributes to the fuel efficiency and other posts that point out that the alternator alters the rate that it recharges the battery base on driving conditions and that affects the the fuell economy. Those are just two examples....I'm sure they're more. That's not to mention the dual VVTI which should impact power and economy. I am not the most technical engine guy, but I think it is helpful to know what we are buying and why. LET THE EDUCATION BEGIN!!!!
