In a nutshell, the 2 Litre class is for vehicles with a 2 Litre engine or under. So long as it’s a naturally aspirated BMW engine in a BMW chassis, then you’re good to go!

The class was initially an extension of the Open class (like all other classes), however it proved so popular that it got its own grid several years ago. Don’t let the fact that it’s limited to 2 Litre stop you though, as there are some extremely quick cars and fierce competition.
