Hybrid Technology and The Porsche 918

Hybrid technology, since its inception has been designed to reduce the impact of the combustion engine on the environment. However, the brand new generation of supercars from McLaren, Ferrari and Porsche has exploited the powerful aspects of the electric motor to enhance the capabilities of the internal combustion engine. Since the first glimpse of the Porsche 918 at the Geneva motor show in 2010 [Top Gear Australia, 2010], Porsche has endlessly continued to further research and develop the system to maximise the potential of the hybrid system. With a 4.6 litre V8 producing 608 bhp and two electric motors the 918 produces an astounding 887 bhp resulting in an extremely impressive top speed of 340 km/h [Porsche Automobil Holding SE, 2014]. But, lets no dwell on the irreverent top speed as the engineering behind the 918 is dedicated to the track. That is, how it converts this power and torque into angular acceleration. How it does this? A traditional petrol powered engine delivers a small amount of torque at low rpms, resulting in a lower angular acceleration, by utilising the electric motors, the 918 can generate 680 Nm of torque at 800 rpm. By employing the electric motors when the petrol motor is least efficient, the ability of these supercars has reached a new level.

Although a 4.6 Litre V8 supercar may seem to be a tool of the past, the Porsche 918 demonstrates the potential of the hybrid engine producing only 70g/km of Carbon dioxide to the Toyota Prius’ (the face of efficiency) 89g/km and similarly with fuel consumption 3.3L/100km compared to 3.9/100km [Toyota, 2014]. Which means that the joy of driving can be preserved as humanity source of oil is reaching a point where cars are becoming less viable as an option. Until so...

...ring. But in today’s modern society, the problems we face are more evolved than those face by engineers thousands of years ago. By reaching a peak in raw ability of automobiles, the necessity these days is to refine the efficiency in order to maintain our way of life, whilst preserving it for future generations.

The principal goals of the Porsche 918 is to develop a supercar that embraces all the technological evolutions in the past couple of years, while making it as efficient as possible. Why does this matter? To the normal person, sure it may be interesting, but to those who appreciate driving, the Porsche 918 and other cars alike, the LaFerrari, McLaren P1 and the Lexus LF-LC, conserve the thrills of driving, while making it possible to do so without compromising the already strained fuel source that is available to us at the moment and into the future.
