Some good quotes from Toyota's engineer Kevin Struyf about the development work concerning 2023:

1. While top speed is never the most important thing, Toyota wanted to improve up on it to have more performance in the faster rounds. They have more drag this year thanks to the removal of two air intakes.
2. Jokers that have been used so far for 2023: improved engine, a new differential setting and an improved chassis that improves front geometry on tarmac.
