New Ford Fiesta EcoBoost Hybrid, with 48V Mild-Hybrid system


There are many possible variations of hybrid technology on cars in this phase of technological development. For some of the vehicle sounds Ford chose the way 48V Mild-Hybrid. Now also Ford Fiesta joins the list of electrified vehicles mHEV with the new version Fiesta EcoBoost Hybrid, which combines a 3-cylinder EcoBoost petrol engine and an 11.5 kW belt-integrated starter generator (BiSG) and 48V lithium-ion battery, capable of providing energy regeneration during the deceleration phase and of providing support to the heat engine during the restart phase, as well as providing for the operation of all the electrical components of the car.

Thanks to this technology the gasoline heat engine is coadivated in situations of greater load, like departures, and relieved of the task of supplying energy to the battery while driving through the alternator. According to data released by Ford, technology allows 5% fuel savings in the NEDC cycle and up to 10% in normal driving conditions in urban contexts. The electric motor can supply up at 24 Nm of torque and its integration has also made it possible to modify the turbine of the heat engine, opting for a larger turbocharger, being able to decrease the sensation of turbo lag thanks to the additional boost of the BiSG.

The system naturally coupled also with technology Start & Stop to optimize fuel economy during small breaks, such as traffic lights and queues in the city.
The same technology that was introduced on the Ford Puma crossover in 2019.
