Aerodynamics

AGV's ultra-lightweight Sportmodular helmet is still my all-time favorite flip-face brain bucket, and the company has backed it up with a more affordable Tourmodular lid focused on longer rides, with the option to add an integrated Cardo comms unit.

The Celera 500L is a truly remarkable design. Otto Aviation says its odd shape delivers an astonishing 59% reduction in drag, so it can cruise as fast as a small jet while using 80% less fuel. Now, Otto and ZeroAvia are giving it a clean powertrain.

Airbus is moving ahead with its vision of aircraft with active wing control, working to mimic the behavior of bird flight with wings that adapt their shape on the fly to optimize aerodynamics and lower carbon footprints.

Zero-emissions airliners are still a long way off, but Lufthansa and BASF have developed a way to improve things right now. AeroShark is an adhesive riblet film that immediately reduces fuel consumption, and therefore emissions, from any aircraft.

UK company White Motorcycle Concepts, best known for the big hole in its land speed racer, has stuck a big hole and a small hybrid system into a three-wheeled police scooter, and says these two modifications can reduce emissions by up to 50 percent.

There's no bike on earth remotely like the bizarre WMC250EV, an electric land speed racer built to slash aerodynamic drag by taking the radical step of tunneling a giant hole through the middle of it. Boy does it look surreal on track in this video.

British company McMurtry Automotive has shown off its new Spéirling at Goodwood. It's a miniature electric hypercar with a Gordon Murray-style fan system that generates more than 500 kg of downforce at a standstill – and 120 decibels.

There's no motorcycle on the planet like this one. British company WMC has put land speed record holders on notice with a 2WD, hydraulically hub-steered electric motorcycle designed around a great big hole it says can reduce drag by nearly 70 percent.

No props, no jets, no rockets – Spencer Lisenby just broke the world speed record for remote controlled aircraft, going transonic using nothing but the wind, and an incredible degree of skill in a highly dangerous technique called dynamic soaring.

The man behind the magnificent McLaren F1 is starting up a new company to produce something even more lightweight and extreme than his most famous creation. The 980-kg Gordon Murray Motors T.50 will begin deliveries in 2020 at a price around US$2.2 million.

Is it a snow plow? Did it just crash into the back of two other cars stacked on top of one another? No, it's a specially prepared hillclimb racer that makes so much power that every bit of downforce counts. Meet Franco Scribante Racing's ridiculous-looking Nissan GT-R.

Capable of swimming at speeds of up to 74 km/h (46 mph), the shortfin mako is the world's fastest species of shark. Scientists now have a new understanding of how it's able to reach such speeds, and they believe that their findings could be applied to improving human technology.
