Has Porsche lost it when they moved the engine of the 911 more to the front? (part 2/2)
Answer: Yes they have.
Reading about the engine of the newly introduced Porsche 911 RSR which was moved forward, my first reaction was one of disappointment. Again another manufacturer going for the most proven solution. You can’t argue with the most successful engine lay-out in racing history, can you?
Of course you can, just for the interest of stirring things up (or confusing people).
Therefore I would like to introduce the following statement: Porsche should have moved the engine even further backwards to create a faster car!
The reason for saying this can be found in arguably the most advanced research domain of kinetics and aerodynamics in existence: airplanes. And not just any paper plane or Dreamliner. I’m talking the white shark equivalents of airplanes: the fighter jets.
Since fighter jets need to be the best at an air-to-air combat, they are all about manoeuvrability. Being able to make manoeuvres so fast no other plan can stay in its afterburner fumes. Since stability is the resistance to change, these modern fighters are designed very unstable. Therefore it is almost impossible to fly them in a straight line without computer aids, but it makes them extremely manoeuvrable. As a consequence, a modern jet fighter can change direction in a blink of an eye.
When researching on the net regarding car engine layouts and the influence on their dynamics*, one sentence describing the dynamics of a rear engined car struck me: “think of an arrow flying in reverse”. I can imagine an arrow in reverse is a very unstable …but it can also outmanoeuvre just about anything!
In short, this unbalance created in the Porsche 911 can be found engineered in the most advanced flying machinery in existence.
Ok, a racing car needs to go straight very fast but changing direction is where time is made up.
Therefore my suggestion: let’s put the engine in the 911 RSR as far backwards as possible (the stability systems of the car can perform the same task as in the fighter) and win races!
Now then, stirred?
