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.

Porsche 918 Spyder stars at the 2013 Frankfurt Motor Show

Porsche stunned the world when it unveiled the 918 Spyder as a massive surprise at the 2010 Geneva Motor Show. Finally, three years later, it gets its full production debut at the 2013 Frankfurt IAA Motor Show. Combining a race-spec petrol V8 with twin electric motors, the 918 trades lightweight purity for enormous all-wheel drive performance and astonishingly low fuel consumption.

Semi-autonomous driving system reduces accidents by 75% [w/video]

Scientists from MIT have developed a semi-autonomous driving system that is proven to reduce acccidents by 75 per cent. A front-mounted camera and laser range-finder identify the car's surroundings while making realtime updates to distances, mapping out the car's movement into 'safe zones'. The system also asseses the vehicle's limits, such as grip, and corrects the car.
