Crazy

We've seen some mad Hayabusa custom bikes over the years, but this one's right out of the box. It ditches the original engine for a massive two-stroke V6, but Meggatech Projects plans to make it look close to a standard Suzuki once it's finished.

It's not every day you see a motorcycle cobbled together from old tractor parts – especially one that looks like this! Called Penny Farming, the bike features a huge front tire, and a steering wheel instead of handlebars.

The YangWang U9 is remarkably affordable for a 1,287-horsepower electric hypercar at around US$236,000. It also rocks a 'DiSus' active suspension system powerful enough to launch the car off the ground, or let it rotate on the spot in a "tank turn."

Slicing huge cruise ships in half, then welding in an extra segment to lengthen them, is more or less a license to print money for cruise operators – so this 'jumboization' surgery is becoming very common. Let's take a look at how it's done.

Ireland's Safehaven Marine builds search and rescue craft, patrol boats and pilot boats designed to operate in "all weather" – up to and including Force 10 storms with waves up to 23 ft (7 m) high. The firm backs this up with some spectacular testing.

In an era where safety, sanity, sustainability, and eco-friendliness have taken center stage, enter Nilu27, stage far-right. America's newest V12 hypercar offers no frills, no driver aids, and only one concession to the digital age in the cockpit.

There's a revolution in workstation design going on and Cluven's $4,200 J20 Gatling Battlestation is just one example of the many outrageous new DESK V2.0 workstations beginning to make work more efficient for knowledge warriors.

What do you get when you cross a KTM 1190 V-twin wedged into a custom steel-tube trellis frame with 46" off-road tires that has hydraulic steering? A Monster Chopper. This is the kinda stuff that happens without proper adult supervision.

It looks like a Lotus in the middle of unscheduled brain surgery, but the Engler V12 is somehow far more absurd. It's the world's fastest quad bike – a 1,200-horsepower pile of evil, rolling malarkey that no sane person should ride in anger.

"This thing's gonna be a chungus!" In the northern tip of Idaho, 70-odd miles from Spokane, Washington, a magnificently silly project is underway: a colossal batpod of a motorcycle with a KTM motor, monster truck wheels, and hydraulic steering.

Internal combustion engines have still got a few punches left in them. Case in point: Kiwi drifter "Mad Mike" Whiddett has unveiled "the wildest drift car I could think of," built around the world's first 5-rotor Wankel rotary engine.

One of the world's most important companies seems set to implode and lose its entire team, after a bizarre chain of events beginning with the unexplained sacking of CEO Sam Altman. The future of AI – and maybe humanity itself – swings in the balance.
