McLaren are having a rough time of it, but Jenson Button's latest penalty at the 2015 Mexican Grand Prix might be overkill.

Despite just 20 cars racing in Formula One this season, the former world champion was penalized a full 70 places.

According to Autosport, the farcical punishment is the result of a series of engine issues:

• 25 places for Honda changing the engine and various components
• 25 places for the same parts being changed again for a different practice session
• 10 places for a new turbocharger added to the first engine change
• Five places for new control electronics
• Five places for a new MGU-H unit

Confused? Nobody would blame you.

And the sanctions have been made even more irrelevant because Button was unable to even attempt a qualifying lap in any case.

As a result of the penalties, Button's McLaren won't be moved from the back of the grid because it is already as far back as it can go.
