Porsche Heritage Moments Series Celebrates 50 Years Of Turbocharging Innovation
In 2024, Porsche marked a significant milestone by celebrating '50 years of Porsche Turbo' in series production. This celebration included a four-part series titled 'Porsche Heritage Moments.' The series highlighted the evolution of turbo technology from its motorsport origins to its integration into production vehicles. Notably, 17 out of 19 overall victories at Le Mans were achieved with turbocharged engines.
Porsche's journey into turbo technology began in the early 1970s, initially in motorsport and later in series production. On October 3, 1974, the company unveiled the 911 Turbo at the Paris Motor Show. This marked the beginning of a legacy that has seen eight generations of the 911 Turbo over five decades.
The first episode of 'Porsche Heritage Moments' delves into turbo technology's roots in motorsport. Timo Bernhard hosts Norbert Singer, a former racing engineer, to discuss Porsche's early victories. They explore the summer of 1970 when Porsche secured its first win at the 24 Hours of Le Mans using turbo engines.
Singer explains how opting for a 12-cylinder turbo engine instead of a naturally aspirated one was pivotal. "To put it simply, we increased the boost pressure and gained more power potential," Singer notes. The Porsche 917/30, built in 1972, exemplified this innovation with its powerful turbo engine.
In the second episode, Bernhard meets Hermann Burst to discuss turbo technology's transition to series production. Burst recalls his work on reducing aerodynamic lift for the 911 Carrera RS 2.7. This led to innovations like the 'ducktail' spoiler and later developments such as the 'whale tail.'
The episode highlights models like the first 911 Turbo gifted to Louise Piëch and the subsequent Turbo models that followed. Burst shares insights on maintaining low rear axle lift through various spoiler configurations over generations.
Water Cooling Innovations
The third part focuses on water cooling advancements with Thomas Krickelberg and Walter Röhrl discussing their experiences with the 996 generation Porsche 911 Turbo S. Introduced two decades ago, this model featured a water-cooled engine and optional Triptonic S transmission.
Krickelberg emphasizes consistent technical evolution as key to success: "One of the secrets behind the success of the 911 series is consistent technical evolution." Röhrl adds that driving a Turbo remains an ultimate dream due to its dynamics and precision.
Beyond Performance
The final episode explores what 'Beyond Performance' means for Porsche Turbo's anniversary. Bernhard talks with Krickelberg and Frank Jung about iconic design elements like Variable Turbine Geometry (VTG) introduced in the 997-generation Porsche 911 GT2.
This model showcased advancements beyond ordinary performance levels while maintaining day-to-day usability. The discussion also touches upon unique features like Turbonite colour accents exclusive to Turbo models today.
The 'Porsche Heritage Moments' series offers an insightful look into how Porsche has continually pushed boundaries over five decades through innovative engineering solutions across both motorsport arenas and consumer markets alike.
