NASCAR has yet to release its 2018 Monster Energy NASCAR Cup Series rule book, but the sanctioning body has provided a preview of some changes to race teams and members of the motorsports media. Here are a few of the changes:

Drivers/teams racing a backup car will have to start races in the back, regardless of whether or not they qualified their backup car. In contrast, current rules allow for a driver to start where he/she qualifies if he/she went to the backup car before qualifying, and therefore, qualified the backup car.

Beginning in 2018, a single-engine rule will be enforced for all races, including the Daytona 500. Backup cars can’t have engines in them when unloaded. Instead, if a team goes to a backup, the engine from the primary must be moved over to the backup.

Also, teams must use a sealed short-block engine in at least 13 races. Those 13 engines must be used in two races; they’ll each be sealed after their first race of use. Teams must use a sealed long-block engine for exhibition races — The Clash at Daytona and All-Star Race. The engines for The Clash will be the engines from the race at Talladega (Ala.) Superspeedway next month, and they’ll be sealed after the Talladega race. The short-block seal includes the engine block, crankshaft, camshaft, connecting rods and pistons. The long-shot seal includes everything included in the short-block seal, plus the cylinder heads and valves.

The complete 2018 rule book is expected to be released in October.
