The DFY, introduced in 1982 was a further evolution of the DFV for Formula One, with a shorter stroke and a DFL bore (bore: , stroke: , displacement ) with at 11,000 rpm, thereby producing more power, but still unable to fight against the turbocharged cars of the day. It was the advent of turbocharged engines in Formula One which sounded the death knell for the venerable DFV, and in 1986 Cosworth returned to the lower formulae preparing the DFV for the newly created Formula 3000, with the installation of a compulsory 9,000 rpm rev limiter, which scaled power back from 500 to ; the DFV remained in this class until 1992. The final F3000 engines gave , almost equalling the 1983 DFV which gave at 11,200 rpm.
