2018 NASCAR Engine Rules
Team will be limited to just 13 engines for the entire 2018 season. Parts limited include; engine block, crankshaft, camshaft, connecting rods and pistons.
In other words... The 2018 engines will need to last at least twice as long as the 2017 engines.
NASCAR will require that an engine is active for 2 races. So, they’ll have to last a lot longer than the current rules package. No longer will it be an engine per race.
Additionally, teams will no longer be permitted a practice/qualifying engine in addition to a race engine. MENCS teams will be required to use 1 engine, for the entire weekend. In the Daytona 500, teams were allowed to swap before the race.
Part-time teams will not be permitted to run two consecutive races without a sealed engine from a previous event.
Backup car: Anther rule change relates to the use of a backup car. If a team is forced to roll out the backup, at any point in the weekend, they will start in the rear. So, if a drivers wrecks in the first lap of first practice, they will start in the rear, assuming they reach for the backup.
