Yesterday yhe Mercedes AMG Petronas Formula One Team unveiled its 2015 Formula One World Championship challenger, the F1 W06 Hybrid.
The team did so ahead of the first day of pre-season testing at the Circuito de Jerez in Spain today.
Drivers Lewis Hamilton and Nico Rosberg revealed the seventh Silver Arrow to compete in the Formula One World Championship, with Nico then taking the wheel for the opening test session of the 2015 season at the Spanish circuit.
“From outside, winter might look like a rest time in Formula One. But this couldn’t be further from the truth”, said Toto Wolff, head of Mercedes-Benz Motorsport. “Long before the end of last season, development work on our 2015 car became the main priority. The winter months are the most intense, with everybody at Brackley and Brixworth working around the clock to prepare for the season ahead. Their dedication is inspiring. It would be so dangerous to rest on our laurels after 2014 – but none of us have any sense that things will be easier now. On the contrary, our motivation is as high as ever. There’s a famous Babe Ruth quote I always say to people: “Yesterday’s home runs don’t win today’s games”. We are fully aware that success is not only hard won but can also be short-lived without the right approach. A lot of things have been put in place – not by one individual but by many individuals working as a team. And this has been about taking the right decisions at the right time, trying to avoid mistakes and, if they do happen, quickly analyzing why. Even if, on paper, things are looking good, we will not fall into the trap of being overly optimistic or trying to make crystal ball predictions because this is not how the sport works. In fact, this is possibly the most brutally honest sport because the stopwatch never lies.”
With a limit of four Power Units per driver, per season in 2015 compared to the five permitted in 2014, the demands on both engine oil and fuel are greater than ever.
With its increased power per liter of displacement, the 1.6 liter internal combustion engine of the Hybrid era also runs hotter than its 2.4 liter predecessor. This requires lubricants that do not get too thin under high temperatures and resist oxidation – balanced with a requirement to minimize friction within the ICE for reduced fuel consumption.
Petronas explained the engine oil must therefore possess distinct thermal characteristics to withstand higher operating temperatures and cylinder pressures, and be optimized to effectively contribute to cooling. The use of Energy Recovery Systems (ERS) also brings the challenge of heat dissipation, requiring an ERS fluid that cools the system effectively. Equipped with a unique formulation to defend against extreme temperature and maintain optimum engine performance.
