front page of our local clasifide ad's paper today was a "FreeWay" made by HMV (high mileage vehicle), they made about 800 of them in the early 1980's in Minneaplis Minnasota, it's been about 4 years sence I last saw one for sale, but they were clamed to get 88mpg (this one is advertized as 100mpg), here is a photo of what one would look like.
so they want $2,000 for a single seated vehicle with "room for a passenger" behind the drivers seat, that has a 350cc gas engine, and I belive automatic transmition simaler to a snowmobile, I figure a better motorcycle engine and tranny and it should proform better in both mileage and speed, so what do you all think? how much is 100mpg worth?
if I remember right, they are simply a 10hp Wisconsin, or Tecumse over head valve (was an odd one) engine like you might see on a go cart, the whole thing was so insanly simple! that is why I'm thinking something like a water cooled motorcycle engine with a 5 or 6 speed tranny, or like toecutter said, a turbo diesel, these might have been avalible with a diesel, but I've never seen one of those for sale.
May get great mileage, but you've got to wonder about emissions. Well, I do anyway.
Motorcycle-based cars (assuming this is classed as one) get to side-step that automotive issue.
Kohler is now making closed loop, fuel injected garden tractor engines, so they're emission-controlled. If you wanted, you could just splap a used 3-way catalyst onto one of their engines, and you'd have an EPA-certifiable 100 mpg car.
