But, this is the situation and we can not do anything about it. But Audi can and should. Which led to the creation of their new 2-liter 4-cylinder turbocharger for the RS5 DTM… and, although with a double volume and number of cylinders (so far 4.0 V8), the machine looks pretty impressive.
For starters, the new engine weighs only 85kg.. The low mass has led to radical changes in the design of the car, say engineers. Now the mass / power ratio is 1.6 kg per horsepower, and it is also important to note that the new turbo engines are about 100 hp. more powerful than atmospheric “eighths”.
How powerful is it? Well, Audi says 610 hp, and the new rules also restrict the fuel flow, which amounts to 95 kilograms per hour. “That may sound like a lot,” says Dieter Gass, Audi Motorspor’s chief, “but it’s not, considering the power of 610HP” However, the rules allow the so-called ‘push-to-pass’ system. It is a real-time overbuster system that increases the power of the 30HP engine for a short period of time. The flow is also regulated and can not be up to 5kg. per hour more than the 95 mentioned.
As for the reliability and resource of the new engine, Audi has conducted simulations on a stand to guarantee 6,000 km of trouble-free work.
