The LA Times reports General Motors (NYSE: GM) saw higher fuel-efficient car sales in March as a reaction to higher gas prices.

"Combined sales of its 12 vehicles that achieve an Environmental Protection Agency estimated 30 mpg or better on the highway topped 100,000 last month, the highest total in company history."

This represents 40% of GM's auto sales for the month. Three years ago, sales of fuel-efficient vehicles only made up about 16% of GM's auto sales.

Analyst have expected auto sales to increase as employment and economic conditions improve. And while it shouldn't be surprising that gas prices are helping fuel-efficient cars gain ground in the opinion of consumers, the leap is quite drastic.

"One example of GM's transformation is that back in 2002, trucks accounted for 54% of sales, cars 43% and crossovers just 3%. Now, trucks represent just 34% of GM's sales while cars account for 41% and crossovers 24%."
