Scuderia Ferrari is getting ready to tackle back-to-back races in North America, with Texas the first port of call. Lorenzo Sassi, Chief Designer Power Unit, explains the most important aspects of the next race. “The Austin track has three interesting facets: the first is what’s known as the power effect, or the importance the output from the power unit has on lap time, which is very high at this track. The second is energy management, because the long straights mean we have to ensure good energy recovery in order to maintain performance on those straights. Last, but by no means least, is the fact the track features many sections that rise and fall, which makes managing oil pressure critical”.
