On a personal note - I like everyone on this forum. There is no BS with Axy, he says exactly what he means. A fine quality. Everyone has their own, unique facets that shine and add a lot here.
As for the gas milage - That may be the way it is outside the US, but we get absolute crap for high efficiency cars here! Europe gets a lot of outstanding diesels. Oddly, diesel in the US used to be cheaper than normal gas. Since high efficiency diesels have been produced, it is more now. heck, Lexus has a HYBRID that gets 42 MPG!!! A normal Toyota Corolla comes close to that! I think we are getting screwed here.
I cannot believe that in the early nineties we had a Geo Metro delivering 50+ miles per gallon - Granted, it was small and light. But you cannot tell me we have not made advances in effiency in the internal combustion engine. I do not know of any non-hybrids that get over 42mpg highway. Grrrrrrrr.
So maybe in EU, a scoot isn't that much better in gas, but a 250cc scoot in the US will over double the milage of ANY car. It is a significant savings for us here. And they are 100000x more fun .
On the other hand, you in USA are very lucky because you have a good possibility of choice.
In the same car model, let's take for example, a medium sized hatchback or medium sized sedan - engines will start with naturally aspirated 1400 cc (110 hp), 1600 cc (125 hp), 1800 cc (140 hp), 2000 cc (160 hp)... then you can buy turbo diesels with roughly the same power...
In USA you will get for the start something like 1600 or 1800 / 140 hp, then V6, then bigger V6, then maybe V8 gasoline (for big cars and trucks/pickups/SUVs)...
Those V6 are not even available here and especially not V8. They are all replaced with turbo diesels (WHICH I HATE!
).
Trust me, our gasoline powered naturally aspirated cars are the same like yours and consume a lot of fuel. It is just that diesel substitution is much stronger here.
For example, in city cycle, average small hatchback 1.4-1.6/110 hp will need 10 l/100 km.
The same hatchback but turbo diesel will need maybe 6 l/100 kms.
For bigger displacements the difference is even bigger. If you have a SUV that consumes 20 l/100 km, it will need maybe 10-11 l of diesel/100 km.
There is really no way to compare scoots with cars, it is two complementing worlds...
