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.

2013 BMW 5 Series Facelift – Saloon, Touring & GT

Facelift for the 2013 BMW 5 Series We knew the next BMW News would be the arrival of a facelift for the 5 Series, especially after BMW accidentally previewed it with a configurator that went online too early. But now the 5 Series facelift is here, and what it lacks in real changes BMW has made up for in photos – they’ve sent us over 200 photos of the new 5 Series – Saloon, Touring and GT – maybe in the hope that a mass of photos will make us think the changes are extensive. They’re not.

Spy Shots: Could this be the 2014 Porsche GT3 RS?

Brenda Priddy & Co. sent us the above photos in an e-mail with the subject line “BREAKING: 2014 911 GT3 UNCAMOUFLAGED!” So, we opened it and found a few shots of Porsche's new rear-engine, mini Panamera in “all black everything” but sporting very little camouflage. If this is indeed the 2014 Porsche 911 GT3 RS, the bodywork is either quite a bit more restrained than that of the outgoing 997.5 GT3 RS, or it's wearing bodywork that won't appear on the 2014 GT3 RS when it debuts at the Paris motor show in September.
