Dealership Upgrades to Boost MPG?

:runaround: I heard that there are upgrades available to the Prius from the manufacturer to boost the fuel economy. Now the numbers thrown around were up to 90MPG but that cant be right. Is there such a thing?

there is a swich on the jap and euro cars that make the electic motor run up to 35mph then it acts like normal chec out priuschat.com bout it but it will void your warrenty

Scam!!! Run the other way!

That would be interesting for sure. We have one as a service car and im going to research this.

I never heard of such an upgrade
