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. The car's aero properties were put to the test at the MIRA vehicle test facility in the UK using fluorescent paint in 60mph winds to highlight its flow dynamics, only visible under UV lights.

Volvo Aims High With Its Self-Driving Car Tech Project

SWEDISH car maker Volvo has announced it will embark on a large scale trial to refine the technology behind its self-driving cars. Volvo is no stranger to the technology having already conducted controlled experiments using ‘road trains’ – cars following each other closely at speed – but this exercise will involve 100 cars being deployed in the busy streets of Gothenburg, Sweden. The project ‘Drive Me – Self-driving cars for sustainable mobility’ is a joint initiative between Volvo Car Group, the Swedish Transport Administration, the Swedish Transport Agency, Lindholmen Science Park and the City of Gothenburg.
