Mike Copeland’s company Arrington Performance unveiled their 1948 Chevrolet Advanced Design 3100 truck called “Zero” at SEMA 2021. The truck is powered by a 6.2 L LSx V8 with a Magnuson 2650 supercharger on top. The company built the motor to run on hydrogen fuel and Kevin Oeste from V8TV reports it makes around 500 horsepower. Behind the motor sits a Tremec TKX five-speed manual transmission from American Powertrain and a Moser rear end with an Eaton Detroit Truetrac limited-slip differential. A set of Forgeline JO3C three-piece wheels (19×9, 20×12) with Continental Extreme Contact tires (235/40ZR19, 305/35ZR20) cover Baer six-piston disc brakes.

Calling this zero emission is a falsehood. Yes, the primary byproduct is water, but there are oxides of nitrogen as well, since air is 78% nitrogen. If they ran this on hydrogen and pure oxygen, emissions would be closer to zero.
