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.
In order to do this, the Project One will employ a hybrid powertrain straight from F1, complete with the turbocharged 1.6-litre V6 engine and a KERS energy recovery system as used in the W07 race car. The final output is expected to be close to 1,000hp, with the engine capable of spinning over 10,000rpm.
