The new four-cylinder petrol engine will have a displacement of 1.8 litres and incorporate direct injection, dual variable timing and turbocharging technology.
The all-aluminium unit will have a maximum power output of 300hp (224kW) and will be compliant with the world’s strictest emissions standards, including Euro 6 and Tier 2 Bin 5 in the US.
Alfa Romeo promises the engine will set a new standard for performance in its category, and create new benchmarks for power-to-weight ratio, fuel efficiency, acoustic and vibrational comfort and driving performance.
Fiat chief technology officer, Harald J. Wester, said the new engine would be developed in Italy for production at the local FMA plant in Pratola Serra from early 2013.
"This is an extremely important step for Alfa Romeo, as we continue to reposition our brand and prepare it for global distribution,” Mr Wester said. “The United States remains our primary objective as we prepare for a 2013 introduction of our models."The dedication of Group-wide resources to develop specific powertrain solutions for the specific needs of Alfa Romeo is a reflection of the renewed thrust we are placing on the development of this brand.“This is a first step in a series of initiatives to be implemented in the near future which will reconnect Alfa Romeo to its historical roots as a premium Italian sports car brand.”
The engine is expected to be at its peak mounted in the middle of the rear-wheel drive Alfa Romeo 4C, which is scheduled for production in 2013.
