Recently, the Crossover B‐Car interior has become very popular and provides some appealing characteristics. We probe users' needs for the interior of a vehicle and propose a draft resolution for interior design, space utilization, and variations in functionality for Crossover B‐Car developers. This study explores the appeal of Crossover B‐Car interiors from the perspectives of usability and functionality. We interviewed 14 experts, using the evaluation grid method (EGM) for expert evaluation to determine the semantic structure of appeal for Crossover B‐Car interiors. Hence, a hierarchical diagram of Crossover B‐Car interior preferences was created to determine the critical factors. We then surveyed 1100 users through a questionnaire. According to the following statistical analysis, appeal factors were affected in varying degrees by particular reasons and characteristics. The results are useful for the designers and researchers of Crossover B‐Car interiors and also contribute to studies in the field of human factors and ergonomics. © 2012 Wiley Periodicals, Inc.
