in the end, what is the purpose? you spend more at the pump but you save possibly thousands in new body panels that go on a car that already has them? how much gas are you planning to save?
if you want to do it because it is cool then go for it. I think that if you were doing it solely for FE then you will probably never realize the gas savings from that investment. I hear that carbon fiber is really expensive (I may be wrong). |

1.5 liter vs 1.6 liter, very different final drive ratios, different valve sizes, different intake manifold shapes and runner size, different ecu, difffernet v-attack actuation point, different redline. lots in common to be sure but quite a bit different too. It would be interesting to see how it worked out! i am getting 38/42 or so with a y5 mini-me in 96 hatch. I drive 70-80 to get the 42ish hwy mileage. I hope to get a little better than that as i dial the set-up in. |

HONG KONG (MarketWatch) -- Nissan Motor Co. will cut the weight of its vehicles by an average of 15% over the next seven years as it seeks to improve fuel efficiency...
I am going with a fibreglass hood thats only $350 shipped for my BMW to cut weight, Lighter seats, no exhaust, and a lighter batter (mazda miata probably to stay cheap). All this and wheels + tires should net around a 200lb weight reduction (on a 2800lb e36 318i). Remember, less weight means less pressure on the tires which equals less rotational friction with the road... I think the less weight the better. Heck, I think cars in the future will go down to around 1500-2000lbs (just like in the old days). |
One factor that I haven't heard in this entire thread so far is the safety impact (pun intended). Mechanical Engineers designed the crash safety of your car based on the ACTUAL parts installed on the car and NOT based on the installation of aftermarket parts. You may be literally risking your LIFE to try to increase fuel economy by reducing weight. Regardless of how much money you've got in the account for car repair emergencies and car insurance deductible, no matter what your car insurance coverage is, no matter how much car insurance coverage the other guy has, no matter how much health insurance you have, in the event of an accident, it's just you, the safety cage of your car, and the physics of the collision between you and another car or you and a stationary object. The crash strength of your car will be the only actual life insurance you've got. The science boils down to: 1) If your car is strong enough to protect you in the collision, you live 2) If your car is NOT strong enough to protect you in a collision, you die. Was the weight savings worth it if the new lighter part is only designed to geometrically fit into the position where the previous part was located without being strong enough for a collision?
