The Steinway Lo-V was a New York City Subway car type built between 1915 and 1925 by the Pressed Steel Car Company, American Car and Foundry, and Pullman Company. These cars were built specifically for use on the IRT Corona Line (currently known as the IRT Flushing Line, used by the 7 train), and the IRT Astoria Line (currently known as the BMT Astoria Line, used by the N train and W train.) They had special gear ratios to climb the steep grades (4.5%) in the Steinway Tunnels, something standard IRT equipment could not do.

The Steinways, which were named after William Steinway, were among the first Low-Voltage cars delivered to the IRT, starting with the 12 car order from Pressed Steel Car Company in 1915. Pullman then built and delivered at least 70 Steinway cars in 1916. In 1925, American Car and Foundry delivered 25 Steinway cars, which would be the last standard body IRT cars built. The last Steinways placed in service were 30 cars converted from former High-V cars and Low-V trailers. These cars were built as part of the 1915 and 1916 orders from Pullman.
The Steinways served the IRT Queens lines until 1950, when they were displaced by the R15s. After that, the Steinways were transferred to the Lexington-Pelham Bay local line, where they served along with older High-V cars until 1956, when they were displaced by the R17s. They were then spread over both IRT East Side and West Side routes, where they remained in service until the end of 1963, in quite limited numbers. A handful of them survived until early 1970, mixed in trains with 1938 World's Fair cars and Low-V trailers, on the IRT Third Avenue Line in the Bronx.
Following their retirement, no Steinway cars were preserved. All were scrapped following their removal from revenue service.
The 1938 World's Fair Lo-V was technically a "Steinway" car, as it also contained the special gear ratios required to climb the grades of the Steinway Tunnels. However, as the World's Fair Lo-V is significantly different, it is a separate and distinct car class and not included in the "Steinway" grouping.
