In both cases, increased torque and power for the 2025 model is aided by turbo technology that was born decades ago. This engineering feat, called variable vane geometry, harnesses and controls airflow to create a driving experience that reflects the brand’s fun-to-drive experience. It harnessed a technology called variable nozzle turbo, which eventually evolved to become the variable vane geometry in Audi models. If high-performance, precision Porsche models could use variable vane geometry, it had to meet the German company’s exacting standards. Variable vane geometry helps the turbo work like a smaller unit at low RPM, and it doesn’t have to bleed off boost at high speeds, Hoch says.
