Write NO MORE THAN THREE WORDS for each answer.
Detroit is convinced that small, stylish, and fuel-efficient cars are what American drivers want. But are
automakers right?
For years, the auto industry's critics have been calling for Detroit to roll out small cars that they say
Americans are demanding for. The question is, do we really want to drive small cars? The answer, according
to some analysts, is already clear. "Domestic auto companies feel forced to offer smaller vehicles because of
pressure from the government." says John Wolconowicz, an auto analyst for IHS Global Insight.
Whether we want the vehicles or not, automakers are devoted to a small-car sales strategy. General Motors
is unveiling (推出) three new small cars-the Chevrolet Cruze, a small car due next year; the Spark, a minicar
due in 2011; and the Chevy Aveo, a compact. Mike DiGiovanni, executive director of the global market notes
that GM is presuming a return to high oil prices that will cause the market to shift to smaller vehicles.
At Ford, there are no plans to abandon production of big trucks. But the company is making small cars a
priority, launching the Ford Fiesta and the C-MAX, a compact car with sliding doors and three rows of seats,
in 2011. "We can't even think about growing our market share without having a strong pressure in the small-
vehicle market" George Pipas, Ford's chief U.S. sales analyst says.
Not everyone is so big on Americans going small. This seems to be evident on dealer lots (停车场). Jack
Kain, a Ford dealer in Versailles, Ky., said the F150 truck remains his bigger seller. He predicts trucks will
continue to outsell small cars, at least in his area "People won't give up the safety and comfort of the larger
cars," he says.
But Ford's Pipas is confident that many will embrace the industry's new focus. Detroit's big hopes, he
admits, are riding on the future of small cars.
