DFV/DFZ/DFR replacement was designed by Geoff Goddard to result in 3498 cc (96 mm x 60.4 mm) HB V8, which was introduced with the Benetton team midway through 1989 making its debut at the French Grand Prix, and won the Japanese Grand Prix that year (Benetton used both the original HBA1 and the development HBA4 in 1989).
