2017 Technical Regulations
2017 delivered the first major aero reset in nearly a decade. Cars returned to a 2000 mm maximum width (from 1800 mm, matching pre-1998 dimensions). Front wings became significantly wider, rear wings lower and wider, and tyres grew to 305/670-13 fronts and 405/670-13 rears (Pirelli supplied the new wider tyres). The package increased overall grip and made cars roughly 3-5 seconds per lap faster than their 2016 counterparts, reversing the deliberate pace cuts of 2015-16. Hamilton took his fourth title with Mercedes.
