Meeke strengthened his lead in the Rally, winning four of the eight super-fast forest speed tests.
The Citroen DS3 driver, who held a strong lead after Friday's action, looks set to deny local hope Jari-Matti Latvala a third win on the trot on home soil after another scintillating performance from the Briton.
"Today has been exceptional. Yesterday was one of the best days I've had in a rally car and today has surpassed that. I don't know where I go from here. We have a job to do tomorrow - play it safe and try to bring it home," said Meeke.
