The current Ford Fiesta ST uses a 1.6L EcoBoost four-cylinder. But the next-generation Fiesta ST could be using a turbocharged three-cylinder.
“We’re seeing more and more of what we can do with the 1.0-litre engine in development and the signs are promising. It’s a great engine – it sounds brilliant and there’s loads of torque when the turbo comes on boost, so we’re looking into things for the next ST,” said Darren Palmer, Ford's head of small cars to Auto Express.
Currently, the most powerful version of the 1.0L EcoBoost three-cylinder produces 138 horsepower. But Ford has been experimenting with the engine to see how much power can be extracted. At the moment, the company has been able to get 202 horsepower.
“There’s still a huge demand for the ST – we’ve seen that with the current ST200. But we want to offer more, so expect more performance and efficiency,” said Palmer.
