I can’t count how many times I’ve heard (or read) folks say that they “wouldn’t buy a hybrid until it gets 100 miles per gallon (MPG).”

A good bit has changed since I wrote about the CalCars.com mod back in the summer of 2005.

That good bit is the price.

Think 100 MPG is so tough to achieve?

Behold the 100 MPG Prius (YouTube) …

As it turns out, all it takes is six grand, a bit of ingenuity, a big box o’ batteries, some cables and other goodies. Truth be told, six thousand dollars is just a start … the ultimate price depends on your choice of battery technology.

Modders rule.
