E85 FlexFuel Engine
There's a lot to be said for doing the right thing. We understand that. The E85 FlexFuel Vortec 5.3L V8 engine that's standard in 4x4 models and available in Tahoe 2WD operates on either regular unleaded gasoline or E85 — a blend of 85% ethanol and 15% gasoline — or a combination of both.
- Because ethanol is made primarily from organic, domestic resources, E85 is a mostly renewable fuel that can help reduce our dependence on petroleum.
- E85 is a cleaner-burning fuel source, which helps reduce smog-forming emissions.
- Plus, E85 ethanol fuel generally has a higher octane rating than regular unleaded gasoline, which can result in slightly higher horsepower and torque levels.
- Chevy has over 2 million E85-capable FlexFuel vehicles on the road.
