With Diesel at $5.00 a gallon I was thinking about scooters yesterday (I know! but my commute is only 10 miles, so why not.) The funny thing is, Scooters "only" get about 80-90mpg. Now I know that may seem like a lot, but a hybrid car in the city can get 50mpg, and that's a whole car, not a 200 lb. scooter.
I realized that scooters don't get better fuel economy because they are super small engines at super high loads, operating at full throttle all the time. It's like if you took a super fuel efficient vehicle like a honda hybrid and floored it all the time wherever you went. Your fuel economy then wouldn't be 50mpg, it would be more like 20mpg. The solution? A diesel scooter. Diesels get about 20% better fuel economy under light load conditions, but that advantage increases to 40-70% under heavy load conditions. That means a comparable diesel scooter could get about 150 miles per gallon, and my trips to work would cost about 35 cents a day instead of $5.00 a day. That's about a thousand dollars a year, money I would be glad to put right back into my truck to make it go faster. Just some fuel for thought.
