weight reduction will yield MUCH better results in lightweight

cars and cars with small engines. If you have a lightweight car AND a small engine, you will most likely see BIG improvement. If you drive a tank, then you might not see much. it is not just about eliminating a certain percentage of weight. it is about how much power your engine can easily produce(larger engines can produce 100 HP easily but a small engine has to work hard to put out that much. and if you want to say that most small engines only need to develop 50 HP then remember that 50 HP is a drop in the bucket for a large engine) and how much less power it will take to get the lightened car up to speed. Our sunfire had to work pretty hard to cruise down the road at 55 mph, but the Green Dart is barely cracking idle!!
