The Pontiac Trophy 4 engine (also called the Indianapolis 4,[1] or Indy 4) is a 194.5 cu in (3.2 L) inline four-cylinder engine[2] produced by the Pontiac Motor Division of General Motors for model years 1961 through 1963.[3] Created from one bank of Pontiac's powerful 389 cu in (6.4 L) Trophy V8,[3] its only application was in the first generation Pontiac Tempest. It was dubbed by Pontiac the Trophy 4,[4] playing off the racing success that had earned the 389 V8 engine the nickname Trophy V-8 after just two years of competition.
