The engineers at Mercedes-AMG developed the engine with a thermal efficiency of 50%

The bad news is that this motor is only for the "Formula-1"

One of the most important indicators of any internal combustion engine is the thermal efficiency. This option is not always published in the instruction manual. It means what amount of the produced during combustion of the fuel energy is converted into real work. For conventional petrol cars, this option is 20 kopecks per cent. The most modern models demonstrate the efficiency somewhere around 30 % and diesel engines of about 35-40 %. Meanwhile, the engineers at Mercedes-AMG managed to design a new engine for "Formula 1" with 50% efficiency.

C 2014 in the "Royal races" are used turbocharged engine capacity of 1.6 liters with a V6 layout. Since then, produces the Mercedes-AMG, but now his efficiency was so high. Apparently, this is the first case in the world, when the real engine that runs on gasoline, has demonstrated such effectiveness. However, while the claimed figure was reached only on a chassis dynamometer, as in a real race, the result may be slightly different.



If to simplify, it turns out that the new engine Mercedes-AMG is capable of half of all produced energy to send to the cause (the rest literally and figuratively flies in the tube). 



Turning to market production vehicles, not to mention the Toyota Prius. Modified for a new generation of hybrid 1.8-liter engine capable of operating with a thermal efficiency of 40 %, a record for gasoline engines. By the way, the engine operates on the Atkinson cycle.
