Elon Musk recently clarified that Tesla’s new 4680 cells are already being deployed in some of its vehicles as prototypes. Even more interesting is that the next-generation batteries have already been in use for several months, though the CEO did not state which of its vehicles are equipped with the 4680 Roadrunner batteries.

The Tesla CEO related his update in a recent post on Twitter. While responding to a question about the company’s strategy with its cathodes and its suppliers, Musk noted that Tesla’s own battery cells are already powering some of its cars. That being said, Musk clarified that ultimately, prototypes such as cars that currently run on the company’s 4680 cells are trivial, as they are incomparably simpler than actual volume production.

There is a primordial drive in certain motorcyclists that can only be satisfied by shoehorning the largest and most excessive engines possible into the frames of two-wheelers. The mighty V8, a staple of the muscle car world, has frequently found itself driving half the wheels it was designed for, but typically there’s been one glaring problem with the resulting motorbikes: they’re colossal.

Take the Boss Hoss, probably the best known V8 bike you can slap some money down and buy. Those things use engines up to 7 and a half liters in displacement, and you’d better bring a packed lunch if you want to walk around one.

Then there’s Nick Argyle’s Rapom V8, which uses an 8.2-liter, thousand-horsepower supercharged engine out of a freakin’ monster truck. That thing’s even bigger, and gets a hilarious four miles a gallon.

The Navy has fielded a 650-round ammo backpack nicknamed ‘Avenger’ to troops at some point in the last two years.


Daimler has unveiled an electric bus equipped with a solid-state battery pack — probably becoming the first planned production EV with a solid-state battery.

The German automaker has been aggressively electrifying its deep lineup of big vehicles from buses to commercial trucks.

This week, Daimler unveiled an update to its eCitaro, the electric version of its best-selling Citaro electric city bus, and the update included the anticipated solid-state version of the bus: the eCitaro G.

Tesla’s Cyberquad electric ATV prototype had its first public outing this week since the unveiling last year, and here we bring you a closer look with a gallery of pictures.

When Tesla unveiled the Cybertruck last year, CEO Elon Musk had a little “one more thing” moment on stage when they brought the Tesla Cyberquad, an electric ATV, to show the loading capacity of Cybertruck’s bed.

At the time, it wasn’t clear whether Tesla planned on making the electric ATV available, but Musk later confirmed that it will be an option for Cybertruck buyers.

You might never have to replace your tires again.


When all-electric vehicles eventually complete their global takeover, they’ll collectively require much less maintenance than their oiled up, transmission-based counterparts. As for the tires? That’s a different story.

To help drivers avoid the misery of waiting around for a tire change, Goodyear has introduced an intriguing new concept: tires that can regenerate new tread on the spot.
