WASHINGTON – President Barack Obama wants automakers to make greener cars at a time when General Motors and Chrysler are hanging by the thread of a massive government loan and auto sales have plummeted to their lowest levels in more than two decades.Obama’s plans could bring smaller cars, more hybrids and advanced fuel-saving technologies to showrooms, but car shoppers will probably pay more up front because the new rules are expected to cost the hamstrung industry billions of dollars.
