The HY-KERS vettura laboratorio (experimental vehicle) is an example of how Ferrari is approaching the development of hybrid technology without losing sight of the performance traits and driving involvement that have always exemplified its cars. This hybrid project is also aimed at ensuring that Ferrari will be in a position to comply with future CO2 emissions standards, particularly in terms of the urban cycle. City driving is traditionally where sports cars are most penalised as their engines are designed for maximum efficiency and performance at high revs, whereas the urban cycle involves low revs and low engine loads.
