Fuel injection in NASCAR

Fuel injection in NASCAR was introduced in 2012, having previously been announced for 2011, which was the last season to see the premier NASCAR series use carburetion. Both the Xfinity Series and Camping World Truck Series use carburetors through into 2021, with no announced change to injection. Cars that compete in the NASCAR Xfinity Series (previously known as Nationwide Series) cars are powered by carburetors; in addition to trucks that compete in NASCAR's Camping World Truck Series.
