Saturn Flex Fuel Vehicles

Factory FFV model

Saturn discontinued production after the 2010 model year and has the smallest flex-fuel footprint of any GM brand. Exactly one Saturn model was ever a factory FFV: the 2007 Relay minivan with the 3.9L V6 engine. The Relay was a badge-engineered sibling of the Chevy Uplander, Buick Terraza, and Pontiac Montana SV6, and it was discontinued after 2007 — making Saturn's FFV production history roughly one year long.

No other Saturn vehicle was ever flex-fuel. The Aura midsize sedan, Vue compact SUV, Outlook three-row crossover, Ion, Sky, Astra, and L-series and S-series sedans all lack factory flex-fuel capability. This matters because the Vue and Aura are common on the used market and are occasionally mistaken for FFVs due to their shared platforms with the Chevy Malibu and Equinox — platforms that did eventually receive flex-fuel variants, but only after Saturn had already exited production.

Saturn-specific E85 tips

Only the 2007 Relay is flex-fuel.

Any other Saturn, any other year, is not an FFV. Decode the VIN and check for a yellow gas cap before filling with E85.

Aura and Vue look like they should be FFVs, but aren't.

Both share platforms with Chevy products that later got flex-fuel variants, but the Saturn versions were built before those FFV introductions. The Chevy Malibu did not get flex-fuel until 2010; the Equinox did not until 2011 — both after Saturn's wind-down.

Used Saturn FFV inventory is thin.

The 2007 Relay was a low-volume, single-year minivan. If you want a GM flex-fuel minivan, a used Chevy Uplander or Buick Terraza is more plentiful and mechanically identical.
