Vauxhall Cascada Convertible: Aimed at hairdressers?

Vauxhall are teasing a new convertible – the Vauxhall Cascada – that appears to be Astra based but stretched and pushed upmarket. We knew Vauxhall (and Opel, for that matter), were planning a replacement for the Astra Twin Top which we guessed would be the new Astrra Cabrio. But it’s not, it’s the Vauxhall Cascada.

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.

How will you get to work in the year 2030?

Imagine a future where New Jersey adopts mass public transit and on-demand jitneys; Boston becomes hyper-dense and walking becomes the primary means of transport; Atlanta disperses even further and relies on solar power, electric cars and Google connected technologies to manage mobility; and Los Angeles tries autonomous cars, but finds the transition difficult, and its gridlock even worse. These are the scenarios proposed in a new study by New York University's Rudin Center for Transport Policy and Management. The report, which proposes scenarios rather than making predictions about the future of transportation in the US, repeatedly points to connected car technologies, autonomous cars and logistics networks as driving forces in regional mobility solutions.
