===The HB V8===
{{Further|Ford-Cosworth HB engine}}
The replacement for the DFV/DFZ/DFR series was the '''HB''' series designed by Geoff Goddard as a {{convert|3498|cc|1|abbr=on}} (96&nbsp;mm x 60.4&nbsp;mm) V8, introduced with the Benetton team midway through 1989, making its debut at the [[1989 French Grand Prix|French Grand Prix]]. It won the Japanese Grand Prix that year (Benetton used both the original HBA1 and the development HBA4 in 1989).

As Ford's de facto works team, Benetton maintained exclusivity with this model through the rest of 1989 and {{f1|1990}}. {{f1|1991}} saw the introduction of customer units, two specifications behind their works equivalents. In 1991, these were supplied to the fledgling [[Jordan Grand Prix]] outfit, and for 1992, Lotus. {{f1|1993}} saw the customer deal extended to [[McLaren]] who had lost the use of their [[Honda F1|Honda]] [[V12 engine]]s after 1992. Using the customer HBA7 (and later a customer HBA8), McLaren won five Grands Prix with triple World Champion [[Ayrton Senna]] that year.

The HBA1 V8 was introduced in 1989. It exploited a narrower 75° vee-angle rather than the 90° used in the DFV series, and was originally rated at approximately {{convert|630|bhp|kW PS|0|abbr=on}}. By 1993, the factory HBA8 V8 engine used by Benetton was producing approximately {{convert|700|bhp|kW PS|0|abbr=on}} at 13,000&nbsp;rpm.<ref>{{cite web|url=http://www.statsf1.com/en/moteur-ford-cosworth.aspx|title=Engine Ford Cosworth|website=www.statsf1.com|access-date=5 July 2017}}</ref> Although the HB V8 was less powerful than the [[V10 engine|V10]]s and V12s used by rivals [[Renault F1|Renault]], Honda, and [[Scuderia Ferrari|Ferrari]], its advantage was that it was lighter and gave better fuel economy.

A Jaguar-badged version of the HB was developed by [[Tom Walkinshaw Racing]] to the tune of 650&nbsp;bhp at 11,500&nbsp;rpm for sports car racing, fitted to the extremely successful [[Jaguar XJR-14]].
