Hyundai Motor Co.
said today the fuel economy of its revamped Sonata sedan was less than it had previously stated, an error that could further undermine the South Korean automaker's reliability after a slew of mileage-related lawsuits.
Unveiling the redesigned model to the media earlier this month, Hyundai told reporters the sedan's fuel economy had climbed 6 percent to 12.6 kilometers per liter (29.6 mpg) from its predecessor.
Hyundai, however, said today that figure was erroneous and had been based on tests at its research center. Government tests showed the mileage had actually inched up just 2 percent to 12.1 kilometers per liter (28.5 mpg).
