Concept
Four years prior to the introduction of the production Jeep Compass, a concept vehicle with the same name had its world premiere in Detroit at the 2002 North American International Auto Show. It featured a two-door body, all-wheel drive and a 3.7-liter V6 engine.

The 3.7 L Power-Tech V6 engine from the Jeep Liberty was not available in the new Compass for 2007, though the production model Compass kept the concept car's styling cues and some of its features. The production model Compass also had four doors instead of the two doors on the concept car.
### Response: The initial engine in the concept was a 3.7-liter V6 engine.
