The 21st century is characterized by new technological developments and a rapid pace of change, challenging the academy to educate students for a future employment market characterized by change and uncertainty. This market requires practitioners to develop a broad set of skills, so-called "21st-century skills," along with more focused practices within traditional disciplines. The present study explores the mutual relationship between intrinsic motivation and the expression of 21st -century skills among students participating in the Formula Student project -- an international competition in which participants design and build a racecar while facing challenges such as independent learning, planning, and execution. We found that students' participation in the Formula Student project enables them to practice 21st -century skills that they will need in their future workplace; this experience, in turn, helps them meet the psychological need for autonomy, competence, and relatedness which are the basis for intrinsic motivation.
