The main objective of Powertrain Research & Technology is the development and application of innovative technologies for the improvement of powertrain performance and for the reduction of engine and vehicle emissions and fuel consumption.
As far as conventional powertrain systems are concerned, most of these technologies are based on the integration of mechanical and/or electro-hydraulic actuation systems with advanced electronic control systems, aiming at managing the air system, the combustion process, the exhaust gas after-treatment and the power transmission systems.
Regarding the new emerging powertrain technologies, efforts are concentrated on the development of cost-effective hybrid propulsion systems, tailored for urban transportation. Furthermore, some exploratory activities are carried out regarding future powertrain technologies, such as Hydrogen Fuel Cell propulsion systems, aiming to identify the relevant problem areas and to investigate their industrial feasibility. The main powertrain technologies under development are:

• the Common Rail technology in the Diesel area and its latest Multijet versions
• advanced after-treatment Diesel technologies, especially for PM and NOx emissions
• an innovative Electronic Valve Control system (Multiair) for the air control in Spark Ignited and Diesel engines
• electronic CNG injection systems
• the Dual Dry Clutch Transmission technology
