Cosmos 4RWF V8 Muscle Bike Roars To Life For 2010

What do you get when you quit trying to build an engine to fit in a motorcycle frame and start trying to build a motorcycle around an engine? This.

The 4RWF takes abandons just about every motorcycle-building convention in favor of a design that looks like it was idly sketched in the margins of a sixth grader’s notebook. It’s part Boss Hoss, part Dodge Tomahawk, and more than a little bit of Batman’s Tumbler from The Dark Knight.

Brazilian mechanical engineer Amadeu Ferreira Junior designed the motorcycle around a 350-cubic-inch, Chevy ZZ4 crate engine, which puts out 355-horsepower and 405 pound-feet of torque. Enough to drive a 4,000-pound hotrod fast, and enough to drive a 1,047-pound motorcycle really, really fast. It offers only three gears, plus reverse, because you’re not going to roll this thing backward under your own power.

What is this thing really capable of when you open it up? We’re not really sure, yet. Cosmos’ promotional video for the 4RWF shows it plodding along at a pretty tame pace on a highway, getting passed by semi trucks. And the design does not look like it takes kindly to hairpin turns. But plant it in front of your friendly neighborhood bike bar, and we’re pretty sure it will spark up conversation.

Not surprisingly, you won’t find the 4WRF on the floor of a non-existent Cosmos dealership any time soon. Ferreira will launch it as a strictly limited-edition machine, and owners will have to custom order the bike to have it built to their dimensions. The price: a princely $93,200, or $82,100 if you decide to go with the tamer two-wheeled version. More information (in somewhat broken English) can be found at Cosmos Muscle Bikes.

Honda unveils sleek electric sedan and SUV prototypes at CES 2025
Honda 0 Saloon and Honda 0 SUV prototypes.

Honda’s next-generation electric vehicles are a step closer to production. At CES 2025, the automaker unveiled prototypes of the 0 Saloon and 0 SUV, the first two of its 0 Series EVs that will start rolling off assembly lines in Ohio next year.

The two EVs follow 0 Series concept cars Honda unveiled at CES 2024. These are closer to what buyers can expect to see in showrooms, hence the label of “prototype” rather than “concept.” How close exactly? When Honda unveils a prototype, that vehicle generally makes the transition to production with minimal changes. But that would be particularly remarkable here.
They still look like concept cars

Sony and Honda’s Afeela 1 EV makes more sense at CES than in the real world
Afeela 1 front quarter view.

The Sony car is almost here. After its creation via a joint venture with Honda in 2022 and two years’ worth of prototypes, the electronics giant’s Afeela brand is finally taking reservations for its first electric vehicle, with deliveries scheduled to start in 2026.

But will it be worth the wait? Coinciding with the opening of reservations, Sony Honda Mobility brought updated prototypes of the Afeela 1 (as it’s now officially known) to CES 2025, representing what California customers (Afeela is only taking reservations in that state) who put down a $200 refundable deposit can expect when they take delivery.
