In the late 1980s and early 1990s, General Motors had a problem. The company needed to sell smaller gas-efficient cars and the way to do it was through imports. Asüna was the captive import brand that GM launched in Canada.
The first model was the Sunrunner, which was a Geo Tracker with a different logo (via Autoweek). The cars weren’t that unique and consumers could cut through the red tape and see that the Sunrunner was a Tracker.
