Does the Ford ST have a Volvo engine?
No. Ford's ST hot-hatch lineup uses Ford-designed EcoBoost engines, not Volvo-supplied powerplants.
The question often arises because of Ford's historical ties to Volvo and the broader use of turbocharged four-cylinder engines in performance models. To understand the answer, it's helpful to look at which engines power the Fiesta ST and Focus ST, and how they fit into Ford's engineering lineup.
Which engines power Ford ST models?
The Fiesta ST is equipped with a 1.6-liter turbocharged EcoBoost four-cylinder that delivers roughly 200 horsepower, with performance tuned for a lively, lightweight hatchback. The Focus ST uses a 2.0-liter EcoBoost four-cylinder producing around 250 horsepower, offering stronger mid-range punch and a higher track-ready feel. Both engines are part of Ford's EcoBoost family and are manufactured and developed by Ford, not Volvo. By contrast, Ford's high-performance Focus RS uses a 2.3-liter EcoBoost, which is a different variant within the same family.
Did Ford ever use Volvo engines in ST cars?
There is no direct Volvo-engine powering the current Ford ST lineup. While Ford did own Volvo from 1999 to 2010 and there was technology sharing during that era, the engines in Fiesta ST and Focus ST are Ford EcoBoost units. Since Volvo was separated from Ford (with Volvo subsequently developing its own Drive-E engines for Volvo-badged models), Ford ST models have not adopted Volvo engines.
Bottom line
In Ford's current ST lineup, Volvo engines are not used. If you want Volvo power in a performance car, you would look to Volvo-branded models or other collaborations, rather than Ford's ST hatchbacks.
Summary
Summary: No, the Ford ST does not have a Volvo engine. Fiesta ST relies on a 1.6-liter EcoBoost engine, and Focus ST relies on a 2.0-liter EcoBoost engine—both Ford designs. Volvo engines are used in Volvo models (and historically involved in some Ford collaborations), but not in the Ford ST performance hatchbacks.
