Green Drive Expo MPG Challenge: Fuel economy over a 34-mile course, held October 9, 2010 in Richmond, CA.

It works perfectly. It is amazing.

"My wife drives to AND from work every day as well as drives workers to lunch and uses no gas at all. Our system can go 35 miles at up to 52 MPH with no gas. If we go farther we can use super hybrid mode and go 100+ miles at 100+ MPG. It works perfectly. It is amazing. It even works in the Phoenix heat. When you use solar like I do it runs for free."

The best way to own and drive an electric vehicle today.

"I am extremely pleased with the 10 KW conversion system! It provides me with sufficient range (~40 miles) that I can tackle my 10 mile commute to work and back, plus extra mileage for running errands, in EV-only mode with ease (includes hills, headlights, radio blaring). The fact that it is minimally intrusive with regards to integrating with the existing Toyota computer and circuitry is a huge plus, as the car behaves like a normal Prius if the system is turned off. The modularity of the conversion kit is reflective of thoughtful, reliable engineering.

"I now have a minimally-modified production Toyota vehicle with all of the great engineering that went into the Prius but with the added bonus that I don't need to burn gasoline to use it. For all practical purposes, I am now driving a real-life electric vehicle with air conditioning, power steering, power brakes, regenerative braking, a great trip computer, etc., all of which would have required significant effort to integrate if I were to have done a full gas-engine EV conversion myself.

"I am very pleased with the system. I think that it is the best way for the average person to own and drive an electric vehicle today, as it is both affordable and practical."

The largest battery of any Prius conversion.

"This kit is the only solution available at a reasonable price that provides substantial EV range (at speeds up to 72 MPH). The 10 KW kit has the largest battery of any Prius conversion."

2,500 miles on a tank of gas.

"Our client got 2,500 miles on his last tank of gas. Over that time, we've been having temps between 10° and 30° F. The system is working really well. Thanks again for all your help and support. We keep telling folks about your product."

My consumption has not dropped below 99.9 MPG.

"You have one satisfied owner of your 100 MPG Prius modification. I have seen over 1,200 miles on a full tank. I gassed up on November 28th and it's now December 26th with still more than half a tank showing. This is normal driving for me. Sometimes only five to 10 miles per day and sometimes in excess of 40. Since filling up, my consumption has not dropped below 99.9 MPG, all at normal highway speed. I am very satisfied. Thank you for placing an excellent product within my price range."
