History Of Porsche Technology
Everything about the Porsche brand is in homage to tradition and heritage. From the company logo based on the Wurttemberg coat of arms to the 911’s engine location, carrying parts of the past forward is essential to this manufacturer. Why would anyone not want to recall this storied past that has dominated Le Mans with the most wins of any manufacturer? As the first German vehicle to make the race in 1951, the 20th place finish was far more than just respectable. But the German mindset and engineering would not remain off the podium for very long. Innovative technology would carry the Porsche line to the front of the pack swiftly and efficiently.
The Transmission Dilemma
The balance between pleasing everyone and no one can be a very fine line. For Porsche, the challenge was to meet the needs of the heel-and-toe aficionados while still keeping the fans of an automatic transmission flocking to their sporty vehicles. The first effort, the Sportmatic, was actually a semi-automatic that gained favor with many. But German engineering is never completed. The next iteration, the dual-clutch PDK, became far more successful because it got the job of shifting gears done more quickly than other types of transmissions.
Porsche Doppel Kupplungs
The Porsche Double Clutch transmission was born for the racetrack. The goal for this piece of technology was the faster transition from one gear to another for faster lap times. The fact that it also offered added fuel efficiency was incidental on the track. However, both of these benefits would garner more attention when the technology found its way to the line production vehicles going to the general public.
Tinkering With The Turbine
A turbocharger uses exhaust gas to power a turbine-driven pump. The pump forces air into the intake manifold at higher than atmospheric pressure. The bigger turbo creates greater pressure to provide a greater air/fuel mixture and a highly coveted increase in power. But in the case of a turbo, bigger is not always better. The increased size results in a heartbreaking lag before the added power arrives. The Porsche solution is Variable Turbine Geometry. Their solution is a happy medium between the larger size with lag and the smaller size that cannot keep up with the air demand at high speed. VTG has been in place on the Porsche turbocharged engines since 2005.
Managing The Temperature Issue
Increased exhaust brings with it increased temperature. To solve this issue, Porsche engineers created an additional water-cooling system to make Variable Turbine Geometry a very doable technology to include on the first-gen 997 Turbo. While new technology can bring new challenges, the mindset and desire to create solutions that will win races and sports car buyers’ hearts always appear to prevail at Porsche.
