Engine Downsizing
Engine downsizing refers to an industrial strategy aimed at reducing the displacement of an engine while maintaining similar performance, thanks to turbocharging, direct injection, and thermal optimization. Very common in modern gasoline engines, engine downsizing offers advantages in homologation and fuel consumption, but also has limitations in real-world usage, reliability, and longevity. Here you will find our dedicated guides and analyses.
