Fiesta 1.25 Engine (2005) - Craggyislander

Hi Guys

Spending some time searching through the forum I'm interested to know where the design of the 1.25 Duratec petrol engine came from? Notes in the forum seem to point to it being a Mazda/Yamaha design - can anyone give a definitive answer?

Thanks very much

The 1.25, 1.4. 1.6 and 1.7 (Zetec-S) engines were designed by Yamaha for Ford, as you might exepct from a company used to making engines that rev to over 12000 rpm they are very crisp and free revving.

The 1.25 has been used in the Fiesta since around 1996 alongside the 1.4 and more recently the additionally the 1.6, the 1.4 and 1.6 are used in the Focus ( and IIRC Fusion) and the 1.4. 1.6 and 1.7 (with VVT) in the Puma.

They are unrelated to the 1.6, 1.8 and 2.0 Zetec engines first fitted to Escorts and Orions around 1991/2, the Mk I and Mk II Mondeo and more recently the Focus Mk I in 1.8 and 2.0 ltr form along side the 1.4 and 1.6 mentioned above.
