The V16 configuration is also used in several large displacement [[diesel engine]]s that are used as marine engines or in rail [[locomotive]]s. This is due to manufacturers often designing an engine around a fixed displacement per [[cylinder (engine)|cylinder]], then adding additional cylinders to the design until the required power output is achieved. For example, the [[EMD 710|Electro-Motive Diesel 710]] engine range uses a displacement of {{convert|710|cuin|L|1|abbr=on}} per cylinder, with the 16 cylinder version (called the ''EMD 16-710'') producing over {{convert|4300|hp|MW|abbr=on}}.

[[GE Transportation]] produces the ''7FD Series'' four-stroke engines (used in marine, locomotive, and stationary applications), which have a displacement of {{convert|668|cuin|L|1|abbr=on}} per cylinder and can produce over {{convert|4400|hp|MW|abbr=on}}. GE also manufactures the GEVO-16, which produces over {{convert|6000|hp|MW|2|abbr=on}}.

Another V16 diesel engine is the ''[[Wärtsilä]] 46F'', which produces over {{convert|25,700|hp|MW|1|abbr=on}} at 600 rpm.<ref name="Wärtsilä 46F">{{Cite web|url=https://www.wartsila.com/marine/build/engines-and-generating-sets/diesel-engines/wartsila-46f|title=Wärtsilä 46F - diesel engine|website=Wartsila.com}}</ref>

In the UK from 1947 onwards, [[English Electric]]'s subsidiary [[English Electric diesel engines]]<ref>{{Cite web|title=English Electric Diesel Engines - Graces Guide|url=https://www.gracesguide.co.uk/English_Electric_Diesel_Engines|access-date=2020-10-14|website=www.gracesguide.co.uk}}</ref> developed a V16 engine for rail and marine use based on its 10" bore x 12" stroke (254mm x 305mm) K series from the 1930s, notably used in [[British Rail]]ways class [[British Rail Class 40|40]] and [[British Rail Class 50|50]] locomotives with power output in the range 2000-3000&nbsp;hp (1492-2238&nbsp;kW) at speeds ranging from 600 to 900 rpm. This engine too derives from a series based on a fixed cylinder size of 942 cu.in. (15.4 L) per cylinder, giving the V16 a total capacity of 15,072 cu.in. (246 L).

Another notable maker to offer the V16 configuration was [[Detroit Diesel]] corporation, especially in their 71, 92 and 149 series [[Two-stroke engine|2-stroke]] diesel engines, with output ranging from around 650 to over 2400&nbsp;bhp (485-1790&nbsp;kW) at speeds over 2000 rpm in the smaller ranges.  Once again these engines were based on common parts (the numeric designation is the cylinder size in cubic inches) and were used for maritime, generator and off-road mine truck applications.  The modular nature of the engines meant that the V16 configuration was built by putting together two V8 engine blocks and the 2-stroke cycle offered excellent power to weight, with the 16V149 being capable of equalling the output of much larger, slower-running 4-stroke engines.

[[Fairbanks Morse]] manufactures the following V16 diesel engines, FM | [[ALCO 251]]F, FM | COLT-PIELSTICK PA6B STC, FM | COLT-PIELSTICK PC2.5 STC, FM | MAN 28/33D STC, FM | MAN 32/44CR, FM | MAN 48/60 CR and the FM | MAN 175D.
