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.
The combination of light weight (642 kg in race trim for 2013), power (900 bhp with the 3.0 L V10, 780 bhp (582 kW) with the 2007 regulation 2.4 L V8, 950+ bhp with 2016 1.6 L V6 turbo), aerodynamics, and ultra-high-performance tyres is what gives the F1 car its high performance figures.
