Umea Institute of Design degree show 2010

Earlier this month, Car Design News attended Umea University's annual degree show. Covering student work from the MA Interaction Design, Advanced Product Design and Transport Design programs and the BA Industrial Design program, it was the first exhibition overseen by Umea's new Rector, Anna Valtonen, formerly head of Design Research & Foresight at Nokia. In a departure from the show's traditional format, this year saw keynotes and workshops spread over two days.

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.

Survey claims winter prompts increase in in-car tensions

NEW research conducted by the RAC puts the traditional winter blues in the shade, as the motoring organisation’s survey has uncovered a new phenomenon: "carguments". According to the RAC’s poll of 1,300 drivers, as many as 54% of motorists say they have arguments in the car – hence the ‘cargument’ - at this time of year when the days are short and the weather is miserable. A total of 15% of drivers and passengers said they argue more in the car than anywhere else, with 19% saying the mere act of driving left them stressed and angry, and 14% feeling cooped up in a car.
