Fernando Alonso will use his second engine of the season in the Bahrain Grand Prix following his accident in Australia, Honda has confirmed.
The Spaniard's McLaren was destroyed in his crash with Esteban Gutierrez during the season-opening race.
Alonso was already set to have a new engine for Bahrain, but Honda was still investigating to see what parts could be salvaged.
The Japanese manufacturer however confirmed on Tuesday that Alonso will need a complete power unit for the second race of the season.
"We have recovered the power unit from Fernando's car used in Melbourne," said Honda F1 boss Yusuke Hasegawa.
"After initial investigations, we are massively disappointed that the ICE and most of the surrounding parts have been heavily damaged, as the impact from the accident was just too great."
Under current rules, each driver can use up to five power units during a season before getting a penalty.
