Mercedes-Benz B-Class aerodynamics tested [w/video]

Mercedes-Benz has produced a video testing the aerodynamics of its new B-Class – which it claims is the most aerodynamically efficient car in the world – using a wind tunnel and fluorescent paint. The W245-generation B-Class has the lowest aerodynamic drag in its segment with a Cd of just 0.26, thanks to features such as serrated front wheel arch spoilers, optimized cooling airflow and a Pagoda roof to help airflow over its profile.
