I started this thread because I didn't want to go too off topic (steal) from the original thread I was posting on (tire pressure) in the HCH forum

I personally don't see any ill effects of running tire max as opposed to manufacturers suggested pressure. They set a pressure that will work for the AVERAGE consumer. They weigh out FE with ride comfort. Most people would rather have a cushy ride than ultimate mpg, even in a hybrid. Just check out reviews on the Insight. Anyone who has driven a (real) sports car, would find the Insight's suspension mild, even with overinflated tires. But the general consumer finds that it beats them up. I personally can't stand the 'float' and lack of control that a soft suspension and sidewalls give you. I love to feel connected with my car, not like I am on a bus ride.

Another point of FE vs comfort issue that has come up on a thread is the intake and exhaust system. They needed to make it quiet at the expense of a few MPG. A large portion of the buyers wouldn't pay 25k for a car that wasn't silent. I think with the auto stop, they made sure it was quieter because you would notice it even more than in a normal car. I may do those mods in the future once I can contact the dealer and find out if it will have any affect on the warranty or after it expires. I would check out a high-flow cat as well if it wouldn't reduce emissions, reduce life of car, or lower torque from less backpressure.

I think once enough of these cars (hybrids) are sold, then the mentality of the public of squeezing every last bit of hp and of torque, will switch to maximizing efficiency and squeezing every last tenth of a mpg. There will be a lot of mods and upgrades for cars in general that will be beneficial to the consumer and the enviroment. The whole thought of - is it worth the price of a product for such a little gain? ... usually relating to the extra cost of the Hybrid in general ... Well, how many people who pay $1000 for a exhaust and intake and realistically get 5-10hp in high rpms at the cost of low end power (i think most lose much more low end than they gain back) complain about it or need, use, feel that much of a difference? They may get a tenth or two faster on a 1/4 mile. So that same $1000 might get you a couple MPG greater FE or more, sounds like more benefit per dollar in my eyes (and you may get a little more power too as an added benefit). Those who spend over 10k on an engine and turbo setup (or most turbos alone are 5k+) for a street car, where you would never see the full performance out of it (legally).

The market isn't there yet, those who are here at GreenHybrid are the ones who are on the ground level, the pioneers, if you like, at how society will turn and in creating the market for a completely new line of products and a new way of thinking. I feel within a decade or two, the performance auto companies will only have racing as a market, and will have to find another venue to remain open.

I know not all things are for everyone. I would sacrifice a few mpg to add extra sound dampening, insulation, and a amp/subwoofer, but I can make that up in other areas. I want to be comfortable and enjoy my investment as well. Otherwise, I would have bought a Hyundai Accent for half the price that gets over 30 mpg combined. I want to be spoiled in my own way while still acheived over EPA and double what the average driver gets no matter what they are in, including Hybrids.

Just my 2 cents
