Team R&D is crucial for improving your car. There are five main departments: 'Aerodynamics', 'Chassis', 'Powertrain', 'Durability', and 'Ers'. Each department has a development tree with various upgrades. You'll earn 'Resource Points' from practice programs and race objectives, which are used to purchase these upgrades. Early in your career, prioritize 'Durability' to avoid costly DNF's. Then, focus on 'Aerodynamics' and 'Powertrain' for raw performance. 'Chassis' improves handling, and 'Ers' boosts energy management. Balance these based on your car's weaknesses and track requirements.
