Mercedes to run all-new power unit on W10

While a lot of attention is on the new aerodynamic changes this winter, Mercedes have also made changes to their power unit on the new W10 car. They launched the new car on Wednesday morning.

Mercedes insist they need to make these changes to stay competitive across the 2019 season. Last year, Ferrari at points looked quicker. Something which the German team don't want to experience again.

What they said

"We've made changes to the cooling architecture of the Power Unit, which hopefully provide aerodynamic benefit on the car and also provide efficiency benefit on the Power Unit - so, hopefully, a win on both the chassis and on the Power Unit," said Andy Cowell, Managing Director of Mercedes-AMG High-Performance Powertrains.

"Right at the heart of the Power Unit is the conversion of fuel into heat release in the combustion chamber and useful work out of the crankshaft. We have made steps on the combustion efficiency and on the ERS system.

"The marriage between the turbocharger assembly with the MGU-H, the inverter, the cells and the MGU-K: that whole system is now capable of operating more efficiently and helping with energy deployment through a race."

The car has already made its on-track debut. Check it out here!
