Charles Leclerc will start the Canadian Grand Prix from the back of the grid after Ferrari introduced further power unit changes ahead of qualifying.
Leclerc already had a 10-place grid drop guaranteed because of Ferrari’s decision to fit his third control electronics system of the season on Friday.
Ferrari had also given Leclerc a new V6, MGU-H and MGU-K – after the power unit failure he suffered in Azerbaijan last weekend – but these components were all within his seasonal allocation.
The decision has now been made to take another batch of fresh components ahead of FP3 – a new ICE, turbocharger, MGU-H and MGU-K.
All of these components breach the seasonal limit, which means Leclerc must start from the back of the grid.
Doing this allows Ferrari to bring as many fresh components into the pool as it can right now, while it is suffering from reliability problems.
Team-mate Carlos Sainz also has a new V6 engine in his car but this is within his allocation so does not result in a penalty.
Leclerc has started the last four grands prix from pole position but will not keep that run going in Montreal, and will likely take part in Q1 but no further sessions.
He is seeking to regain ground in the championship after losing potential victories in each of the last three races to different problems but this weekend will now be an exercise in damage limitation.
