Amid all the drama of the F1 title showdown, it's easy to forget this is the final race for the current generation of power units before sweeping changes are introduced in 2026.
While the 1.6-litre V6 base is unchanged, we say goodbye to the MGU-H, while MGU-K get a big hike in power output. That should stop the massive gulf in performance and reliability that afflicted the teams when the regs were introduced back in 2014 and led to a sustained period of Mercedes ultra-dominance.
This will also be the final outing for DRS, to be replaced with a manual override engine mode.
