Currently, six different Evolution Series models (seven including rebuilds), have been produced for the North American market.

Gevo, Inc. is an American renewable chemicals and advanced biofuels company headquartered in unincorporated Douglas County, Colorado, in the Denver-Aurora metropolitan area. Gevo operates in the sustainability sector, pursuing a business model based on the concept of the " circular economy ".

Gevo creates protein-rich additions to the food chain and advanced renewable fuels simultaneously, and also powers processes that create additional energy sources, such as renewable natural gas and green hydrogen.

Gevo’s product lines focus on utilizing carbon captured from photosynthesis, and highly efficient production processes to deliver cost effective drop-in hydrocarbon fuels and chemicals. These fuels and chemicals also deliver real carbon abatement to address a growing value added market.

Gevo transforms renewable energy and bio-based feedstocks into energy-dense advanced renewable liquid hydrocarbons. These liquid hydrocarbons can be used for drop-in transportation fuels such as gasoline, jet fuel, bunker fuel, and diesel fuel, that have the potential to reduce waste, increase efficiency, and create a new homegrown energy source.

List of engines produced by GE Transportation Systems and GE Jenbacher (GE Energy). Where possible, recent examples of usage are shown. GE GEVO-16, 16-cylinder engine used in locomotives, such as the GE ES59ACi, [6] GE ES58ACi, [6] GE ES57ACi Diesel Locomotives. GE PowerHaul P616, 16-cylinder engine used in GE PowerHaul series locomotives. [9]

The GE (General Electric) Evolution Series (or simply "GEVO") is a series or line of high-powered, energy-efficient, six-axle diesel locomotives which first debuted in 2005, and is still currently in production (with prototypes or testbeds built from late-2002 to mid-2003).

Gevo is commercializing the next generation of renewable gasoline, jet fuel, and diesel fuel with the potential to achieve zero carbon emissions, addressing the market need of reducing greenhouse gas emissions with sustainable alternatives.

All are powered by the GE GEVO engine. The Evolution Series was named as one of the “10 Locomotives That Changed Railroading” by Trains Magazine and was the only locomotive series introduced after 1972 to be included in that list. Currently, six different Evolution Series models have been produced for the North American market.

Evolution Series locomotives are equipped with either AC or DC traction motors, depending on the customer's preference. All are powered by the GE GEVO engine. The Evolution Series was named as one of the "10 Locomotives That Changed Railroading" by Trains Magazine and was the only locomotive series introduced after 1972 to be included in that list.
