Ferrari introduced a new power-unit to the grid in Russia.

Ferrari used three of their remaining engine tokens for improvements to the V6 Turbo-Hybrid power-unit in a bid to improve performance and reliability issues.

Ahead of that particular Grand Prix weekend motorsport.com suggested the changes to the power-unit was to improve the combustion of the engine.

They explained: ‘The modifications should allow it to raise the compression ratio inside the cylinder ? which will lead to increased exhaust gas flow that will help the turbo perform better.’

It was hoped these modifications would provide a double whammy for Ferrari, not only increasing horsepower, but also improving the efficiency of the Energy Recovery System.

The only problem was Ferrari didn’t really get to see the benefit over the course of the race with Sebastian Vettel punted off the track and into the tyre barrier in turn 3.

Ferrari must have been suitably pleased though because now customer teams Haas and Sauber will also get the new power-unit for Spain.

Haas will also test some additional upgrades and will compare their data with their previous evaluations from the pre-season winter test.

?For us it is quite a good thing, We can go to Spain and look at the data we had from the test and compare it to see if we have gone wrong somewhere, or if we are still in the ballpark because the car felt good there.

?It is the first track we have been on where we have got data so it is nice to be able to compare what we had before there.?
Haas F1 Team principal Gunther Steiner told motorsport.com.
