The 10 fastest cars in the world is always a fun list to compile, because the common denominator of each entry is speed, and speed also happens to be the coolest and most exciting force a moving object can produce. Right now, the car industry is amidst a speed renaissance of sorts, in which new technologies are either replacing old technologies or finding ways to coexist with them. A perfect example of this is the power unit in the Mercedes-AMG Project One, which borrows a compact six-cylinder engine and amplifies it beyond belief with electric motors and hybrid power systems. As we near the year 2020, the automotive landscape will be all about finding speed with new propulsion systems and energy management.
