What was the name of the first car to have power steering?

The first production car to offer power steering was the Chrysler Imperial.

Chrysler introduced its hydraulic “Hydraguide” system for the 1951 model year. It was standard on the upscale Crown Imperial and available as an option on other Chrysler models, including the New Yorker and Imperial. The system used hydraulic pressure to reduce the effort needed to turn the steering wheel, especially during parking and low-speed maneuvering.

The innovation arrived as American cars were becoming larger and heavier, with wider tires that increased steering resistance. Engineers had experimented with powered steering earlier, including systems for military and heavy vehicles, but the 1951 Imperial is generally credited as the first production passenger car with commercially available power steering.

A common mix-up is confusing the first car with the first manufacturer: Chrysler developed and marketed the technology, while the Imperial was the model that introduced it to ordinary car buyers. Power steering later became common across the industry and eventually evolved from hydraulic systems to electric assistance.
