Fernando Alonso will get use of a revised Honda power unit for the Malaysian Grand Prix but will start at the back of the grid as a result.
Having mulled over whether to introduce a final engine upgrade for the 2017 season ahead of the Sepang race, McLaren and Honda have agreed to go ahead and run it in Alonso's MP4-31 in FP1.
REVEALED: The new 2017 Formula 1 World Championship
With McLaren forced to change the ICE, TC, MGU-H, and MGU-K, Alonso has already amassed 30 positions worth of grid penalties before his car has turned a wheel this weekend. As a result, he is almost certain to start the Malaysian Grand Prix at the back of the grid.
Honda says the new power unit features a 'lighter engine block and a re-designed exhaust, which boosts efficiency'. However, though the changes are designed to help performance, they are not 'targeted at outright performance'.
