{{Further|Ford-Cosworth EC / ED engine}}
The HB was developed into the {{convert|3498|cc|1|abbr=on}} (100&nbsp;mm x 55.7&nbsp;mm) '''EC''' V8 for the 1994 season. This engine, producing about 740&nbsp;bhp @ 14,500rpm, was badged as Ford Zetec-R, and [[Michael Schumacher]] won the [[list of Formula One World Drivers' Champions|Drivers' World Championship]] with Benetton (his first of a record 7 championships), in {{f1|1994}}. This was the last Ford-powered F1 title.

For the [[1995 Formula One World Championship|1995 season]], the F1 engine regulation changed to 3 litres, and the EC's bore and stroke were changed to 94mm x 53.9mm, resulting in {{convert|2992|cc|1|abbr=on}} '''ECA''', which was introduced at about 600&nbsp;bhp, and developed to 610 to 630&nbsp;bhp at 14,000rpm. It was exclusively used by the [[Sauber]] team, whose biggest success of the year was [[Heinz-Harald Frentzen]]'s third place at [[1995 Italian Grand Prix|Monza]].<ref>{{Cite web|url=https://www.statsf1.com/en/moteur-ford-cosworth.aspx|title = Engine Ford Cosworth • STATS F1}}</ref>

Customer unit Cosworth '''ED''' (not badged as Ford Zetec-R) for non-works teams was also made for 1995 with about 580&nbsp;bhp for [[Simtek]] (called the EDB), [[Pacific Racing]] (EDC) and [[Forti]] (EDD) teams. [[Minardi]] continued with Magneti Marelli engine management as per their HB in 1994, this version having the Cosworth designation '''EDM'''. At the first test with the EDM, [[Luca Badoer]] reported that this engine felt less powerful then the 3 litre 9000rpm rev limited engine he had used to win the F3000 championship in 1992. Cosworth later updated the ED to '''ED 2/4''' for [[Tyrrell Racing|Tyrrell]] with {{convert|2995|cc|1|abbr=on}} (94mm x 53.95mm) displacement for 600&nbsp;bhp, which was used until the end of {{f1|1997}} season. The ill-fated [[MasterCard Lola|Mastercard Lola]] team initially entered in 1997 using the Ford ECA engine used by Sauber in 1995 and Forti in 1996. However the team withdrew from the championship before the second round of the season in [[1997 Brazilian Grand Prix|Brazil]], having failed to comfortably failed to qualify for [[1997 Australian Grand Prix|the first race in Australia]].
