Crazy

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 1,817-horsepower Venom F5 hypercar has been unveiled in production form, along with acceleration figures that would suck the doors off a Koenigsegg Regera and sights firmly set on the recently vacated title of "world's fastest production car."

Ever since wingsuit flying took off as an extreme sport around the year 2000, people have been wondering if it'd be possible to stick a motor on one, and give it the ability to accelerate and climb. The answer is yes, as you'll see in this video.

MotoAmerica's King of the Baggers race was a crazy idea, pitting some of the least-racy motorcycles in the USA against one another around California's famous Laguna Seca racetrack in a knee-dragging, luggage-dragging, motor-popping spectacle.

Take one visibly unstable three-wheeler from the 1970s, and give it five times the horsepower and 200+ km/h (124+ mph) top speeds thanks to a screaming superbike motor ... This truly frightening, roided-out Bond Bug has just gone up for auction.

How often does an average hypercar get to hit top speed? This beast would let you unleash the full power of an electric drivetrain plus 4,000 pounds of jet thrust any time you hit the runway, with 500+ mph airspeeds, huge range and aerobatic chops.

Everyone's favorite Bulgarian electric ultracar company Alieno has unveiled the all-singing, all-dancing, all-robotic interior of its fantastical Arcanum – which, you'll remember, makes up to 5,221 horsepower and 8,880 Nm (6,550 lb-ft) of torque.

On its first test ride, ostensibly to break in its tailor-made 3-liter flat plane V8 engine, the Eisenberg EV8 managed to crack 207 mph, or 333 km/h. This is one frightening, but somehow enticing, piece of engineering – and it's yours for US$130,000.

Today's car designs are mostly variations on a familiar theme, but a hundred years ago, profoundly weird ideas like the Leyat Helica had their chance to compete. Basically a wingless aircraft, it was lightweight, very fast, and a really bad idea.

The supercar of the year – perhaps indeed the decade, early though it is – has finally fully launched, and we've now got a trove of images of the first car that Formula One/McLaren F1 design genius Gordon Murray says he's truly 100 percent happy with.

The Hercules 6x6 is coming, placing an extra rotating dollop of rough-hewn testosterone on each side of what was already the world's most outrageously overcompensatory SUV. And yes, it'll have a Military Edition loaded with James Bond gadgets.
