Honda will introduce a minor engine upgrade at this weekend's British Grand Prix, aimed at delivering an overall power boost as it seeks to build on its recent success.
Both Fernando Alonso and Jenson Button will receive the upgrade, though it doesn't require a new unit, therefore Button will use the same unit he raced with in Austria, whilst Alonso will run a new power unit for strategic reasons.
The upgrade, which has cost Honda two of its remaining 12 tokens, focuses on recovering the horsepower lost from the internal combustion engine following the introduction of an upgraded turbo in Canada, by improving combustion efficiency.
Therefore it isn't expected to deliver a huge step forward.
Honda now have ten tokens remaining, one less than Mercedes, whilst Renault have 21. Ferrari have spent the most, leaving the Italian outfit with just three.
