Decoding GM’s 2026 FlexFuel Strategy

by

In an era dominated by news of rapidly accelerating electrification, a quiet corner of the automotive market continues to utilize a different kind of alternative energy. For the 2026 model year, General Motors (GM) has renewed its commitment to FlexFuel, which offers a compelling blend of high-octane performance and agricultural sustainability.

While many manufacturers have phased out E85 compatibility in favor of hybrid or electric powertrains, GM’s strategy remains pragmatic: utilizing the existing internal combustion infrastructure to deliver enhanced performance to those who need it: owners of their heavy-duty trucks and popular small SUVs.
