WHY ???

Hi,

Can anyone please help me understand why fuel efficient vehicles (cars and minivans) like those with 660 cc engines are not available for the North American consumer?

They are produced in Japan, China, India and other countries and
are being sold in most of the world's markets except the North
American one.
Let me give you some names so you know what I mean:
Mitsubishi eK-Wagon,
Honda Vamos,
Subaru Stella,
Mazda Az wagon turbo,
Peugeot 107,
Suzuki wagon r2,
Nissan Moco,
Toyota Aygo,
...and the list can go on.

These kind of vehicles will help the consumer with fuel expenses
(aprox.4 liters/100km.) and also minimize our oil dependency.
Looks like a win-win situation.

Thank you for your advice.
