Ferrari are taking an engine upgrade to this weekend's grand prix on the streets of Baku.
After the Italian team dominated in Monaco, their title rival Mercedes hit back hard recently with a one-two in Canada.
Now, for the unique Azerbaijani venue incorporating a super-long 2km straight and 370kph top speeds, La Gazzetta dello Sport claims Ferrari is bringing an engine upgrade.
The newspaper said that the development is part of the Scuderia's "aggressive development plan" under technical boss Mattia Binotto's direction.
The decision to bring it to Baku was reportedly on the basis of exceptional figures on the test bench.
