The EMD 710 is a line of diesel engines built by Electro-Motive Diesel (previously General Motors Electro-Motive Division). The 710 series largely replaced the earlier EMD 645 series. The EMD 710 is a large 2 stroke diesel engine that has 710 in³ (11.63 l) displacement per cylinder. Since its introduction EMD has continually upgraded the 710G diesel engine. Power output has increased from 3800 hp on 1984's 16-710G3A to 4300 hp as of 2006 on the 16-710G3C-T2.
Over the production span of certain locomotive models, upgraded engine models have been fitted when they became available. For example an early 1994 built SD70MAC would have a 16-710G3B, where an SD70MAC built in 2003 would have a 16-710G3C-T1.
All EPA Tier 1 and EPA Tier 2 compliant models of the 710 are equipped with EFI.
