Current world champions silver arrows are according to Andy Cowell, head of the engine department, have made progress with their drive unit for this season, and the biggest step they took was in the field cooling, where they had quite a few problems last season.
New rules hybrid powertrains are essentially the same since the introduction of Formula 1 leta 2014 forward. Search for more capacity it’s getting harder for engineers, especially considering this year’s season with 22 races, where teams will be able to use each race car for the entire season without penalty only after three internal combustion engines, turbo blew, units MGU-H in MGU-K. "We had to develop a wider area of the entire powertrain and analyze each individual assembly. I hope that the achieved result of the work will help to make the race car on the track faster,”So Cowell.
Mercedes is in a six-year hybrid period Formula 1 with its engine has made progress in power, performance and reliability, and they are even more proud of thermal efficiency, which from 2014 to 2019 grew above 50 percent. “Perfection does not exist, because there is always the possibility of improvement, which is also the guiding principle of the whole team,”Adds the engine chief. “We always try to improve every detail, be it on a race car, a tool, software or safety. We know the areas in which we want to improve, so we are also self-critical enough."
Last season it was W10, the predecessor of the new car W11, tortured in heat conditions. For the first time, we were able to notice this more concretely in the race for GP of Austria, where we had to pass both racers poorer settings engines so that they could even reach the finish line. For this reason, they have worked hard to improve cooling for this year's car. In addition to the larger ones radiators the team focused on increasing cooling efficiencyso that the engine can run smoothly in hot conditions. “We focused mainly on coolants that could perform their function at higher temperatures,He added Cowell.
