Lisa M. Stewart 0 Posted April 17, 2009 Report Share Posted April 17, 2009 I am doing a survey for a capstone engineering project. Our product is an attachment to brake pads on the Prius.The product is able to increase the Prius by 6 mpg, and will cost around $600 to install. If the product takes about 5 years to pay it off, will you be willing to purchase the attachment?I am also looking for comments, both positive and negative, about such a product. Lisa M.

Stewartwonder to know how it work, is there any interference, and the 6 mpg a theoretical or practical, depend on any specific driving behavious / traffic conditions?generally take 5 years to pay off is OK to me as I really love Prius and love to make it perfectbut if it takes 3 years only to pay off, I will definitely get one.

DJKOR 125 Posted April 17, 2009 Report Share Posted April 17, 2009 How about supporting my Nigerian friend instead who requires your bank details so he can place his money somewhere more secure. He promises to let you keep 25% or USD$1 million.No need to feed the spambots. Quote Link to post Share on other sites

SuperDave 18 Posted April 17, 2009 Report Share Posted April 17, 2009 I'm curious to know how brakes, the things that slow you down, improve economy? Also good brake pads for the Prius have been out for ages, it does use the same front callipers as the ZZE122... Quote Link to post Share on other sites

Regenerative breaking :) $600? I'd put my finger on it being quite along the lines of the Autospeed Prius mods. Edited April 18, 2009 by the_random_hero Quote Link to post Share on other sites

The only way regenerative braking will regenerate more is if it takes longer to stop. So the brake pads would need to be worse than the stockos. In which case may as well use EBC Green Stuff Unless I'm missing something in how the Prius works... Quote Link to post Share on other sites

You won't get more energy from slower braking, since you are still loosing the same amount of energy just over a longer time. Regen braking in the Prius works by running the electric motor as a generator (ie the interia of the car is the engine powering the electric motor, as opposed to the electric motor powering the car). The only energy that can be inputed into the system is the conversion of the kinetic energy of the car into electrical energy in the generator/motor (and vice versa under acceleration) - the car has the same amount of kinetic energy to lose regardless of how fast or slow you brake (but efficiencies could well be different, which might create noticable differences) Edited April 20, 2009 by Hiro Protagonist Quote Link to post Share on other sites
