The 2022 guidelines don’t simply overhaul the aerodynamic philosophy of the Components 1 vehicles, however the energy items endure a major change this 12 months as properly. And Mercedes Excessive Efficiency Powertrains’ Managing Director Hywel Thomas defined precisely why the constructors’ champions had labored simply as laborious on the engine aspect over winter.

Mercedes’ newest in a sequence of informative movies sees Thomas, who took over from Andy Cowell in 2020, sit down and discuss concerning the main adjustments coming to energy items in 2022. These adjustments embody the implementation of E10 gasoline – comprising 10% ethanol, which is able to scale back CO2 emissions general – and a freeze on efficiency growth for the facility unit from March 1.

“What we have got with the chance with the brand new automobile is to take a basic relook at issues, and in some ways in which offers us extra alternative and it sparks the passion, and it sparks the creativeness of the engineers much more to make that set up nice,” stated Thomas.

“The change to the bio-content being ethanol, what which means is: the engine goes to react barely in a different way to the gasoline. Some areas of the efficiency we’re actually pleased with, and different areas… truthfully, we’re much less blissful.

“What we’ve to do is change the gasoline the place we will and the change the {hardware} of the PU the place we will in an effort to maximise the impact of the issues we do like and minimise the impact of the issues we do not,” defined the top of the Brixworth-based engine producers.

“The change this 12 months to go to the E10 [fuel] might be the most important regulation change we’ve had since 2014. So, it was a sizeable endeavor to ensure that we actually developed that gasoline and… should not be underestimated how a lot work that took,” he asserted.

The aforementioned engine freeze, mixed with the aerodynamic adjustments, imply that Mercedes HPP (and naturally rival producers Renault, Ferrari and Purple Bull Powertrains) must repackage their energy items to suit the brand new vehicles.

“With 2022 being an all-new chassis… There are areas on the automobile which shall be very delicate to lap time and there are different areas on the automobile which can be much less delicate. What we are attempting to do on the PU is to ensure we keep as distant as we will from the delicate areas to provide as a lot flexibility as we will for the automobile designers, and to package deal elements of the PU into areas the place there’s much less sensitivity.

“What which means is working hand-in-glove with the chassis division, with all these engineers, to ensure that the PU matches in precisely the place it must, to ensure we will make the quickest general package deal,” stated Thomas.

“So, with the brand new gasoline, the freeze to the efficiency of the PU over the course of the season and the entire new automobile, the entire new aerodynamics and becoming the PU inside it, there’s a enormous problem for everybody concerned, particularly the crew up in HPP,” he concluded.

We’ll see the proof of Mercedes’ efforts on observe in Barcelona on February 23-25 – after they launch their W13 automobile on February 18 – as they purpose to realize a file ninth-straight constructors’ championship this season.
