Named the Fiesta Ecoboost Hybrid and Focus Ecoboost Hybrid, the two models will feature Ford’s 1.0-litre Ecoboost engine mated to a 48V belt-driven starter motor. The use of that system, which can deploy extra electrically generated torque under acceleration, has allowed Ford engineers to fit a larger turbocharger.
