Today Stellantis inaugurated the new one eDCT Plant in Mirafiori. We are talking about the new plant for the production of innovative electrified transmissions for hybrid and PHEV vehicles of the Group's brands: a plant that is fully part of the project Mirafiori Automotive Park 2030, which involves an investment by Stellantis of over 240 million euros to transform the site into a one-of-a-kind hub worldwide, completely renovated and designed to host design, engineering and technology, production, supply chain and circular economy activities .
Record numbers
Right away a couple of numbers about this new plant: it is spread over a production surface area of 16,400 m2, has a capacity of 600,000 units per year (approximately 2,100 units per day), will employ 500 employees once fully operational (we are talking about the end of 2024, at the latest early 2025) and enjoys a level of automation of 45%.
Two levels of electrification
The new eDCT modular transmission is characterized by two levels of electrification: Hybrid and Plug-In Hybrid. In the first case we are talking about 48 Volt units, with electric-only autonomy of between 1 and 2 kilometres, battery capacity of around 1.5 kWh and a reduction in WLTP cycle CO2 of between 15 and 20%, while in the second case switches to 400 Volt, the autonomy increases to around 60-80 kilometres, as well as the capacity increases to 10-15 kWh and the CO2 reduction increases to 50-65%.
Accessibility and modularity
Flexibility for two levels of electrification is not the only advantage brought by this new electrified transmission. In fact, it is also an accessible and modular solution for electrified propulsion systems up to 420 Nm of maximum torque, which is 93% composed of components common to Hybrid and PHEV, which helps to ensure not only rather high efficiency but also an excellence of production systems.
Electrified ambitions
As mentioned, its production will be concentrated in the new eDCT Plant in Mirafiori. In Stellantis it took about 18 months to start production: the process itself is divided into four micro-processes, ranging from pre-assembly to testing through main assembly and dressing. The eDCT produced in Mirafiori, in parallel with the one built in Metz, France, represents, according to Stellantis, cutting-edge yet cost-effective hybridization technology, which integrates a 21 kW electric motor into a dual-clutch transmission: the engine provides electric propulsion in scenarios where less torque is needed, such as city driving or constant speed driving, and thus allows the internal combustion engine to remain off for 50% of the time in the urban cycle. If more torque is required, at that point the internal combustion engine is activated.
