Ford has added a new, 7-speed dual-clutch automatic transmission to its range for vehicles with an electrified EcoBoost-Mild hybrid drive train. As an alternative to the manual 6-speed manual transmission, the new 7-speed automatic is expected to be available on request from mid-March, initially for the Ford Fiesta * and Ford Puma * series – each in combination with the 1.0-liter EcoBoost Mild hybrid drive (48-volt technology). The sales prices will be announced in good time. This automatic transmission ensures a plus in driving comfort, especially in the city and in stop-and-go traffic – with reduced fuel consumption and lower CO2 emissions at the same time. In addition, the fast, jolt-free gear changes contribute to the harmonious power delivery of the mild hybrid petrol drive.
The Ford EcoBoost Mild Hybrid drive is a 48-volt mild hybrid technology and thus the entry into the world of electric mobility. This means: At lower speeds, the EcoBoost petrol engine in the Ford Fiesta and Ford Puma is supported by an electric motor – more precisely: by a belt-driven integrated starter / generator (BISG) with an output of 11.5 kW (16 hp).
The electric torque support ensures a powerful, immediate response from the turbo gasoline engine, especially when the engine speed is low. At the same time, the mild hybrid system makes it possible to use a larger charger. This provides more power, but usually also results in a slower response.
The torque support of the starter generator can bridge this “turbo lag”.
The Ford Fiesta and Ford Puma with EcoBoost Mild Hybrid technology cannot be connected to an external power source. This is also not necessary, because the air-cooled 48-volt lithium-ion battery (10 Ah), which supplies the electric motor (BISG) with power, is automatically charged by the braking system when the vehicle coasts and brakes (recuperation).
The EcoBoost mild hybrid system continuously monitors how the vehicle is moving and when and how intensively the battery is being charged. From this it calculates when the stored energy can best be invested in propulsion. Depending on the driving scenario, mild hybrid technology improves fuel efficiency or performance:
- Torque replacement:
The belt-driven starter generator BISG delivers torque (up to 24 Newton meters) during operation, for example when accelerating from a standstill, which the gasoline engine does not need to generate. Compared to the equally powerful petrol engine variants without mild hybrid technology, this improves fuel efficiency and thus also CO2 emissions by up to five percent.
- Torque allowance.
The belt-driven starter generator BISG intervenes as an electric motor as soon as the gasoline engine calls up full power. This increases the maximum torque. In combination with the new 7-speed automatic, the acceleration of the Ford Puma with 1.0-liter EcoBoost mild hybrid engine and 92 kW (125 hp) is up to four percent better than the non-hybrid version .
The Ford Puma with 1.0 liter EcoBoost mild hybrid drive and 114 kW (155 PS) accelerates with the new 7-speed automatic from 0 to 100 km / h in just 8.7 seconds.
The dual-clutch architecture ensures harmonious power delivery and optimized gear changes: In “Sport” mode, the new 7-speed automatic transmission in the Puma EcoBoost-Mild Hybrid makes better use of the low gears – for sportier dynamics. A quick downshifting of the gears is also made possible for maximum acceleration, for example when overtaking. For the three Puma ST-Line variants (ST-Line, ST-Line X and ST-Line Vignale), manual shifting is also possible using the standard sporty paddles on the steering wheel.
The optional availability of the new 7-speed automatic transmission for vehicles with EcoBoost-Mild Hybrid drive is a further step for us on the way to offer all Ford customers attractive access to the ongoing electrification of our vehicle fleet”, says Roelant de Waard, General Manager, Passenger Vehicles, Ford of Europe.
Advanced driver assistance systems
The system adapts its own speed to the vehicle in front and brakes to a standstill if necessary and starts off again automatically after a brief stop of less than three seconds.
The engine can also be started remotely using the FordPass app, for example to use the air conditioning to cool the interior of the vehicle.
The Ford Fiesta EcoBoost-Mild Hybrid and the Ford Puma EcoBoost-Mild Hybrid are two of 17 electrified vehicles that Ford will be launching in Europe this year.
