Mitsubishi Motors Corp.'s Pajero sport utility vehicle is among roughly 10 models tested using a method not compliant with Japanese regulations to gauge fuel economy, sources close to the matter said Friday.

Mitsubishi Motors is expected to gather new data in accordance with Japanese standards and submit it to the transport ministry, the sources said.

The 10 models also include the RVR, the Outlander and the i-MiEV electric car.
