One day we'll all live in a world where smartphones and tablets will be as thick as a sheet of paper. With the rise of nanotechnology in the electronics sector, components now are so tiny you can't see them with the naked eye - sending heavy, unwieldy consumer products to their deaths.
In a largely mechanical sense, Formula 1 has followed a similar path. Designers and engineers alike are joined in pushing current technology to its limits, making components smaller, lighter and more powerful.
Over the past 20 years F1 cars have become increasingly shrink-wrapped, especially around the engine cover, as the internal components are arranged with the same intricacy as a Swiss watch. Giorgio Piola's illustration of the 2018 Williams neatly shows just how narrow contemporary designs have become at the rear.
