It tells you what the paragraph is going to be about.
An F1 hybrid (or filial 1 hybrid) is the first filial generation of offspring of distinctly different parental types. F1 hybrids are used in genetics, and in selective breeding, where it may appear as F1 crossbreed. The term is sometimes written with a subscript, as F1 hybrid.
As a result, 2014's F1 engines make roughly 600 bhpâaround 150 fewer than last year. To make up for that loss of power, they're allowed beefier hybrid systems than before. Yes, that's right: F1 cars are hybrids.They have been so since 2009. Until now, that hybrid power has meant an 80 bhp boost courtesy of a kinetic energy return system, or KERS.et's start with Formula 1, if for no other reason than it's got a 1 in the title, and so numerically it comes first. For many racing fans, F1 is king of the hill, the ne plus ultra of purpose-built race cars.
