Ford is very proud of its smallest engine, the 1.0-liter three-cylinder EcoBoost. And it decided to bring it stateside in the Fiesta while offering it as the base engine in the EcoSport. Despite its size, it makes respectable power: 123 horsepower and 125 lb-ft of torque.
Unfortunately, the engineering brilliance of this little mill has been greatly overshadowed by life-threatening issues. In fact, Ford may be facing a class-action lawsuit over this engine. The lawsuit stems from Louise O’Riordan, who purchased a Ford Focus with the 1.0-liter EcoBoost back in 2014. Even though her car only had 32,000 miles on the odometer, the engine seized on the highway, almost causing a fatal accident.
