Mercedes has made strides to cure its weakness racing in hot conditions which has prev💖iously hamstrung its power unit performance by installing larger radiat🍌ors and making its cooling more efficient for the W11.

The reigning Formula 1 world champions launched its 2020 challenger at Silverstone yesterday, 168澳洲幸运5官方开奖结果历史:revealing key tweaks to i🌄ts car concept aimed to allow greater developme꧙nt throughout the upc൲oming season.

Despite having stable regulations for 2020, Mercedes power unit ꦡchie🃏f Andy Cowell says its investigated “every single system” for areas to improve with the major focus centring on its engine cooling.

Mercedes has frequently suffered at extremely hot races, or races like the Mexican Grand Prix where cooling is trickier due to thinner aඣir at higher altitude, and the trend continued in 2019.

Its first failure to claim victory in 2019 occurred at a hot Austrian Grand Prix, with Valtteri Bottas in third place a🥀nd Lewis Hamilton in ꦉfifth place, before a similar pattern occurred at the Singapore and Brazilian rounds.

Fo🤡r 2020, the Mercedes-AMG F1 M11 EQ Performance engine has larger radiators than its predecessor while the team has focused on making cooling more efficient by 𝔍getting the engine to work at higher operating temperatures.

“We are putting significant effort into making sure that all the cooling fluids on the Power Unit operate at a higher temperature,” Cowell explained. “This incr꧟eases the temperature difference between that coolant fluid a🅠nd the ambient temperature that we are racing in, which increases the effectiveness of the cooling system.

“That’s a tough challenge though, because large parts of the engine are made from aluminium and the temperatures that🌳 we are operating at mean the material properties are decaying quite rapidly.

“Managing that over an eight-race distance Power Unit cycle [average race span required under F1’s technical regulations] ꦡis a tough engineജering challenge but that's what we are striving for.

“As Power Unit engineers we don’t just focus on crankshaft power, we also focus a tre𝓀mendous amount on the packaging and reducing the overheads for the aerodynamicist, so that the𓄧y can mainly focus on keeping the car planted through the corner.”

Mercedes has also targeted tighter packaging around the power unit to improve its aerodynami๊c sco💫pe in its ongoing strive for overall performance.

“We have had to develop an even wider area of the PU. We have looked꧟ at every single system,” Cowell added. “We have worked on a huge array of projects, and when summed together they will hopefully help propel the car around the track quicker and give the aerodynamics team more opportunities to improve as well.

“There is no such thing as perfection, there is always the opportunity to impro⭕ve and all of🎉 us have that mindset.

“We’rꦗe always improving every detail - the materials, the hardware and ingreಌdients, but also things like our design tools. You know there are areas where you can get better. Being self-critical and keeping an open mind is at the core of that mindset.”

Mercedes has estimated its 2020 power unit will be its most efficient engine🌳, able to pr🌠oduce 50% thermal efficiency, up from around 44% from its 2014 power unit at the start of the V6 turbo hybrid era.

Bottas was first to get behind the wheel of Mercede🤪s’ W11 during the team’s shakedown at Silverstone on Friday, before reigning world champion Lewis Hamilton gets his first taste of his new machinerღy.

The team is targeting F1 history by becoming the first team to notch up seven consecutive♛ world drivers’ and constructors’ crowns.
