Kubiak was named as the team's new offensive coordinator yesterday having led former team the Houston Texans into the league's top 10 on offense in four of the past six seasons.
"It's not going to be Texans offense or the Broncos offense. It's going to be the Ravens. It's going to be what we build with our players and our coaches," Harbaugh told reporters.
"It's going to look like what Baltimore wants it to look. It's going to be rugged. It's going to be rough. It's going to be tough, physical, downhill, precise football.
"I think there is a really good fit philosophically. We see football from the same perspective."
The Ravens were ranked 29th in the NFL in total yards last season.
