And crude oil costs are high in 2022, because of the lingering results of the coronavirus pandemic, provide chain breakdowns, high inflation and the ongoing invasion of Ukraine by Russia.

At superspeedways like Alabama's Talladega and Florida's Daytona International, where velocity is limited by a restrictor plate rule, long traces of drafting vehicles make the most of the automobile in entrance to allow greater speeds and better gasoline effectivity.

In 1960, on the second Daytona 500, Johnson was behind the wheel of an underneath powered Chevrolet in competition with several dominant Pontiac cars on the observe at the moment including one pushed by Bobby Johns. Kurt Romberg, chief aerodynamicist at Hendrick Motorsports, stated as little as one p.c drop in drag is worth an enchancment of about 10 positions on the starting grid at Daytona.
