Subaru BRZ Turbo confirmed

Subaru BRZ Turbo - which should be good for 300bhp Subaru in the US has confirmed that they are planning to build a turbo version of the new Boxer engine in the BRZ to create the Subaru BRZ Turbo. Finally, after promises that it was on its way for what seems like ever, we saw the arrival of the production versions of the Subaru BRZ and Toyota FT-86  at Tokyo (which had a small name change and arrive as the GT86).

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.
