The drive train of the Mercedes team has reached a new milestone on the test stand in Brixworth: 50 percent thermal efficiency. This means that for the first time more than half of the energy that could theoretically be generated from the quantity of petrol in the tank is actually used.
Used in the sense of driving the car; For energy is also about the hot exhaust gases which are blown into the air useless. The discipline of thermal efficiency has gained particular importance in Formula 1 since a flow rate of 100 kilograms of petrol per hour has been set.
The old V10 suction engines, which many fans want back in Formula 1 mainly because of their screaming sound, converted less than thirty percent of fuel energy into power. At the beginning of the hybrid era 2014, this conversion rate was at 44 per cent a remarkable advance. But the development did not stop,”writes the Mercedes team in a blog on its official website.
“Three and a half years after its debut, the Mercedes Power Unit has now reached a conversion efficiency of more than 50 percent on the test stands in Brixworth. In other words, it now produces more power than lost energy,”it goes on. A remarkable milestone for every hybrid engine and especially for a pure racing engine.”
milestone on time for the premiere of the Mercedes-AMG Project ONE
How fast technological development in formula 1 is progressing proves a very impressive number: Mercedes has succeeded since 2014, from the engine at the same fuel consumption to get 109 PS more power! The degree of thermal efficiency is thus close to that of diesel engines used in heavy container ships.
For Mercedes, the 50-percent milestone arrives on time for the premiere of the Mercedes-AMG Project ONE, in which a real Formula One engine is built. The super sports car also reaches an efficiency level of more than 40 percent with its filling station base. And even goes one step further than the current formula 1. Using an electric front axle with two more electric motors, to recover even more brake energy.
