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.

Nissan NV200: Nissan’s take on the London Taxi

Nissan is taking on the Black Cab market with the Nissan NV200 London Taxi, expected to go on sale in 2014 from around £30k. It may not be the biggest market in the car world, but the profile of the London Taxi makes it a worthwhile target for car makers. Mercedes recently took on the traditional Black Cab with their Vito-based taxi and did a very good job – but at a price; the Mercedes Vito Cab costs around £42k, almost £10k more than the traditional London Taxi.
