Formula 1 is as much an engineering contest as a sporting one, and our technical coverage explains how the cars actually work — from the power unit and aerodynamics to the rules that shape them.

Start with our beginner's guide to the 2026 regulations, then explore the deeper explainers below. If you're new to the sport, this is where the jargon — MGU-K, downforce, ground effect — gets translated into plain English.
