Not a mass-market product, but another fantastic anomaly in automotive engineering is the hydraulic system used to power the accessory systems in the Mercedes 600; the classic chariot of late-20th century despots and celebs.
It ran on mineral oil at a nominal pressure of IIRC 3200 psi. Could cleanly slice a finger off if poorly maintained & it sprung a leak in an inopportune corner of the system. All this to ensure that the auto's accessories operated with all the smoothness and silence that befitted a head of state.
