Grids will be decided using the qualifying format from the 2013 World Touring Car Championship, with a two-part qualifying format. The opening qualifying session will run for 20 minutes, with the second (involving the fastest twelve cars from Q1) running for 10 minutes.

The grid for the first race will be based on the combined results of Q1 and Q2. The first ten drivers of the combined Q1 and Q2 results will started in reversed order for the second race.

The series will also have a success ballast system, although it uses a model more familiar to those who follow the British Touring Car Championship: 30 kilograms is awarded to the winner of the previous meeting, with 20kg for second place and 10kg for third.

The series will adopt the FIA points scale of 25-18-15-12-10-8-6-4-2-1 for the top-ten race finishers.

Two teams have already indicated a strong interest in joining the championship, with 2013 FIA European Touring Car Cup Single-Make Trophy champions Target Competition confirming they will compete with SEAT León Eurocup cars.

Also known to be interested is the Onyx Race Engineering squad, which has confirmed that it will develop Ford Focus racers for the championship, after being forced to abandon its plans to enter this year’s FIA World Touring Car Championship.
