Engine downsizing is the trend in the automotive industry to build smaller and more fuel-efficient engines without impairing efficiency. The key strategy is to replace cubic capacity and the number of cylinders through technical innovations such as charging or direct injection.
A modern, turbocharged four-cylinder engine often achieves significantly better power and torque than a conventional six-cylinder engine.
The greatest advantage of downsizing is that engines become more economical and environmentally-friendly without losing power.
