Hispano-Suiza is one of those companies that fragmented into different parts all with the same name. Rolls Royce is the same, both the cars and the jet engines both have the name but are in fact made by completely different companies.
Yeah, the Spanish side worked on cars, while the French arm was told to drop the cars in the 30's and concentrate on aircraft engines. The French arm, I think as a result of the occupation, then adopted some really bizarre name from about 1940 onwards.
With Rolls-Royce, it's a little different, as they scaled back car production during WWII as the War Office persuaded them to manufacture V8 Renault's under licence and design their own ones. The separation of the engineering aims was slow in RR's case as most of their business came from aircraft engines during the interwar period and both of the titular founders concentrated on aeroengine design, showcase piece being the Merlin, coming out shortly after Royce's death. So I'm not sure if they were different companies per se as with HS. *shrug*
Henschel & Son, on the other hand... good lord, they made shitloads of different things that by the time of WWII, it was definitely distinct divisions that designed engines, tanks, aircraft & other sundry vehicles.
