EV-spec off-roader for the world’s toughest race. 

Every February, King of the Hammers descends on Johnson Valley, California. What began as 12 teams vying for bragging rights and a case of beer has transformed into over 530 competing teams, 80,000+ in-person spectators, and two million viewers tuning in online. As the pinnacle event of the Ultra4 off-road racing calendar, its organizers are dedicated to continually redefining the limits of racing. That’s why they teamed up with Hypercraft to create the first ever EV-spec off-road race series. With component partners Dana/Spicer Electrified and AEM EV, Hypercraft designed and engineered a complete spec electric powertrain that was then handed off to 11 lucky teams to integrate into the off-road vehicle of their choice.
