<P> 1: 18 scale diecast replicas are 1 / 18th the size of the real vehicle . Most popular in this category are 1: 18 scale automobile replicas--usually made out of zinc alloy (zamac) with plastic parts . "1: 18 scale" is the colloquial reference to this class of toy or replica . </P> <P> Virtually all 1: 18 scale models produced in recent years have opening doors, hoods, and trunks along with functional steering wheels which turn the front wheels . Tires are often mounted on workable' springy' suspension systems . Normally the hood / bonnet lifts to reveal a detailed and accurate engine bay (whether this is a separate cast piece or simply a portion of the cast and painted body located between the fenders). </P>
