Pirelli will introduce a sixth dry weather compound tyre to their lineup for 2023, with the 'C0' set to be added to the range.
The tyre maker usually nominates three tyres - a Soft, Medium, and Hard - for each Grand Prix weekend picked from a selection of compounds ranging from C1 (hardest) to C5 (softest).
The C0 is based on the current C1 band of tyre, with a new version of the C1 set to be introduced.
"The new C1 was tested in Texas and it offers more grip, as the old version of that tyre wasn't as grippy," said Pirelli motorsport engineer Simone Berra.
"The current C2 to C5 tires remain exactly the same in terms of composition."
Which tyres are being tested in Abu Dhabi?
Pirelli will be testing the C1 to C5 range and both wet compound tyres at the post-season Abu Dhabi test.
A total of 12 sets will be provided to each driver between each, with 10 sets provided to young drivers between the C3, C4, C5 and both wet compounds.
