Chang Ho Kim is an old friend of mine, a top-notch mechanic specializing in Hondas, and a championship-level autocrosser, so I need to link to this post at a green-car blog.
When Chang heard about a fuel economy competition, he dusted off a 1989 Honda CRX HF that was sitting behind his shop, tuned it up, lowered it (to reduce wind resistance), installed snow tires (to reduce rolling resistance), put on the funny-looking cow-catcher you see here, and had a go.
And won, achieving a 118-mile-per-gallon average and beating some fancy hybrid machines in the process. So surprising was Chang’s low-tech approach that contest organizers hyper-scrutinized his fuel consumption, but in the end he won fair and square.
Follow the link above to read how he did it, and keep in mind that there’s more than one way to skin a cat: light weight and skilled driving are your best friends whether you’re racing or saving fuel.
