The driver's world championship and manufacturer's world championship are separate championships, but based on the same point system. The series currently consists of 13 three-day events driven on surfaces ranging from gravel and tarmac to snow and ice. Each rally is split into 1525 special stages which are run against the clock on closed roads. - A co-driver is the navigator of a rally car in the sport of rallying, who sits in the front passenger seat. The co-driver's job is to navigate, by reading off a set of pacenotes to the driver, often over a radio headset, due to the high level of noise in the car. The co-driver tells the driver what lies ahead, where to turn, the severity of the turn, and what obstacles to look out for. This role is particularly critical in high-end rally competitions such as WRC. Co-drivers are also often called on to perform maintenance on the car during road sections and special stages, such as changing a wheel. - Sergio Cresto ( USA ) ( January 19 , 1956 -- May 2 , 1986 ) was the co-driver of Henri Toivonen at the Lancia Martini team for the 1986 World Rally Championship season .
