Hyundai says it overstated mileage for revamped Sonata sedan

Hyundai Motor Co. said it overstated the gas mileage of its revamped Sonata in publicity material for the media.

South Korea's largest automaker said Monday it was a mistake that a tentative mileage figure from internal tests was included in a presentation to reporters.

The government Friday said the mileage of the upcoming Sonata was 12.1 kilometers per liter instead of the 12.6 kilometers Hyundai said on March 4.

Hyundai vice president Hwang Chung-yul had touted the new family sedan's fuel economy, saying it was a 6 percent improvement from its predecessor's 11.9 kilometers.

In 2012, Hyundai and its affiliate Kia were found to have overstated gas mileage on 900,000 vehicles sold in the U.S. They agreed to pay up to $395 million to consumers as part of a settlement.
