As well as a suite of tuning options, you can delve further into car maintenance through the team management system. Along with new vehicles, and repairing damage to them, your money can be spent on service crew to help you keep on top of things between stages, consisting of a crew chief and several engineers. Engineers have particular specialisms that reduce the time it takes to repair certain components, so should be hired on the basis of what you tend to damage the most when driving. Your crew chief will gradually become more experienced as you finish stages, too, which increases the efficiency of the crew overall. Once engineers are experienced enough, you’ll also be able to choose perks that reduce the development time for upgrades.
