The 2.5L inline-six engine found in the 2004 Chevrolet Tracker was a General Motors engine, specifically the Atlas LL8. This engine was not unique to the Tracker; it also saw service in other GM vehicles of the era, like the GMC Canyon, Chevrolet Colorado, and Isuzu i-Series pickups, among others. It represented a step up in power and refinement compared to the smaller four-cylinder engine also available in the Tracker.
This particular powerplant was designed to offer a balance of performance and fuel economy for small SUVs and trucks. Its six-cylinder configuration provided smoother operation and more torque than a comparable four-cylinder, beneficial for towing and off-road driving, activities often associated with the Tracker’s intended use. The introduction of this engine into the Tracker lineup was a response to the growing consumer demand for more powerful compact SUVs. It helped position the vehicle as a more versatile option in its class.
