Regarding the recognizability of the engine technology - it's fascinating to know how much materials science technology has filtered down from F1 into road-going cars.

The high-revving (9000RPM) F20C1 Inline-4 from the Honda S2000 has a peak piston speed that matches the highest-revving F1 engines at 25 m/s. The BMW S54B32 Inline-6 from the E46 M3 nearly matches the naturally-aspirated efficiency of F1 engines, at 14.3 bar mean-effective pressure (MEP).

We can also thank F1 and similar racing series for composite cylinder liners, titanium valve springs, hydraulically actuated cams (e.g. BMW's Double-VANOS), hydraulically actuated clutches (e.g. BMW's Sequential Manual Gearbox), dual-clutch transmissions (e.g. Audi and BMW Dual-Sequential Gearboxes), ceramic-composite brake rotors (e.g. Porsche PCCB), direct port fuel injection, etc.
