Williams, Force India and Manor will get use of the latest specification Mercedes engine as used by the factory team in 2016, the manufacturer has confirmed.
Mercedes introduced an upgrade to its power unit at the Italian Grand Prix in September as part of a new development direction with fuel supplier Petronas, but a limitation of resources at Brixworth meant it couldn't be rolled out to Williams, Force India and former customer Lotus.
Nevertheless, Mercedes AMG HPP managing director Andy Cowell says it was a short-term disadvantage for long-term gain, with Williams, Force India and new customer Manor now able to run the latest specification engine from the opening round in Australia.
“The upgrade that we introduced in Monza last year took a huge amount of effort from the factory at Brixworth and we only had enough resource to supply the works team with the latest spec at that time. However, that is now paying off for every team with Mercedes power, as we've managed to build on that development work through the autumn and winter period.
“Now, all our customers are getting an improved package that is exactly the same specification as the works team. All eight Mercedes powered cars will have exactly the same hardware and performance potential come Melbourne - which is a good step for everyone."
