NASCAR could introduce hybrid race cars by 2022

But it's still determining how hybrid tech fits into stock-car racing.

NASCAR has been talking about hybrids for a while, but it has kept quiet about a timeline. Now, the association says hybrid tech could show up in its vehicles by 2022. "We travel the world visiting other sanctioning bodies and are not ignorant to the fact that the world's going towards more hybrid technology," NASCAR's senior vice president for racing development John Probst told TechCrunch.

NASCAR is still determining how it would use hybrids. They may be better suited for shorter courses with more turns and braking, which would put the regenerative braking to use. The hybrid tech would likely be used in parallel with internal combustion engines to add power, rather than solely improve gas mileage. For instance, Probst says the hybrid tech might provide a kind of strategic supercharge that could be used to provide extra power to complete a pass.

NASCAR says it's taking things one step at a time. Its Next-Gen race car just completed its first on-track tests and is set to debut at the 2021 Daytona 500. It will release its Next-Gen race car guidelines in 2021. Then, we'll likely see some type of hybrid tech. NASCAR isn't alone in this push. IndyCar is planning to switch to 900-horsepower hybrids in 2022 as well.
