Rare foreign cars head to Carlisle this weekend

Every spring, Carlisle, Pa., (otherwise known as the Woodstock of the classic-car hobby, a title it now fully shares with Hershey) hosts a weekend event just for foreign cars. Last year, over 1,000 cars gathered in central Pennsylvania, with rare foreign machinery making its way from all over the lower 50 and parts of Canada. The longest-traveled cars we spotted last year wore British Columbia plates, which should give you a clue as to the event's following, though we're still unsure which cars we spent the longest time gawking at.

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.
