Moreover, to control costs and ensure safety, the FIA has set new regulations allowing only eight new engines to be activated throughout the year, with only one engine allowed to be activated in each race; otherwise, a penalty for engine replacement must be faced.
In later years, this standard was further reduced to allow only four power units to be used throughout the year, prompting engine suppliers to focus more on durability and reliability, to prevent the "bomb" from blowing the cylinder on the track frequently.
It turns out the regulations are effective; at least the common nickname "Cylinder Explosion King" of this era has basically disappeared in later years, at most referred to as a tractor.
Currently, in the Brown GP Team's garage at the Catalonia Circuit, there are only two spare power units for the RA108, with nowhere to replace them if damaged, as the Honda F1 Engine Factory has long been closed.
