Facts & History

Notes from the marque

The Willys-Knight was Willys-Overland's answer to a question most Toledo buyers weren't asking: what if a car's valves never clattered at all? Its Knight-licensed sleeve-valve six ran quieter than any poppet-valve engine of its day, and the marque built more of them than nearly every other manufacturer in the world combined.

  • Power came from an inline six-cylinder Knight sleeve-valve engine displacing 255 cubic inches and producing 70 horsepower, running on a 126-inch wheelbase chassis — the longest of the three offered in 1929.
  • The 66 series debuted in 1925 as the most expensive line Willys-Overland built; by 1929 it had evolved into the 66-A.
  • A new 66-A Varsity Roadster carried a factory price of $1,850 — a substantial sum in 1929, roughly equivalent to a well-appointed luxury car today.
  • Sleeve-valve engines traded easy manufacturing for a genuinely quiet, smooth-running motor, at the cost of burning more oil than a conventional poppet-valve design — a known trade-off enthusiasts of the marque accept as part of the ownership experience.
  • Willys-Overland built Willys-Knight models continuously from 1914 until late 1932, when the Depression pushed the company back toward its lower-cost, poppet-valve Willys line.
