Gasoline engines still prevail in the European medium-low PC segments and offer a number of advantages:
• robust and low-cost emission control technology (3-way catalyst)
• intrinsic cost advantage compared to diesel, expected to widen in future.
Technological challenge for gasoline engine is to drastically reduce fuel consumption and improve the fun-to-drive factor, through
• Progressive adoption of turbo-charging technology to improve performance, with emphasis on torque and driveability
• Introduction of breakthrough technology (Multiair) to significantly reduce fuel consumption through throttle-less operation
• Substantial reduction of engine displacement (downsizing) through synergic integration of above mentioned technologies
• Gradual introduction of direct fuel injection as technology’s cost decreases.

• Transmission technology will evolve in next decade under pressure of following, presently conflicting, drivers:
‣ Increasing customer demand for high-comfort automatic transmissions
‣ Higher transmission efficiency to reduce fuel consumption
• Automated manual transmissions (AMT) have very high efficiency but comfort level still not completely satisfactory
• Conventional automatic transmission has adequate level of comfort but fuel economy penalty will become increasingly unacceptable
• Dual-Dry-Clutch transmission (DDCT), combining high comfort and high efficiency at affordable cost, represents the needed technological leap forward

Natural gas propulsion is only technically and industrially available solution for ultra-low emission urban vehicles in the medium term, while waiting for long-term hydrogen option
Natural gas, biofuels and hydrogen are only alternatives to crude oil
Fiat Powertrain, presently leader in natural gas propulsion technologies, aims to further increase its competitive advantage by
• extending natural gas engine/vehicle portfolio (cars-trucks-buses)
• adding bio fuel option (tri-fuel versions) to current bi-fuel (natural gas – gasoline) cars
• adopting, natural gas – hydrogen blends in special urban fleets to promote development of hydrogen infrastructure

Hybrid propulsion technology provides consistent fuel consumption reduction in urban missions, but with very high add-on cost
Fiat Powertrain considers Diesel hybrid propulsion promising forurban light commercial vehicles and buses, and is currently developing the technology for the Daily and Ducato platforms
