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 Panamera – 25,000 built already

Porsche has built 25,000 Panamers in the first year of production Big, exotic cars tend not to sell in big numbers. Annual production in the low thousands is usually as much as you’re likely to see from a supercar and once you get to hypercar levels you can be talking single digit annual production. They’re the rules.

Mazda 3 (2014)

The third-generation Mazda 3 is the also the third model from the Hiroshima-based company to be developed under its much-flaunted ‘Skyactiv', high-efficiency mantra and its Kodo design language. Outside it's a clear relative of the previous Kodo (Japanese for ‘soul of motion') Mazdas, the D-segment 6 and CX5 compact SUV. Its DRG is familiar from those cars with a deep, five-sided grille with a sharp chrome accent that spears into the wide lamps.
