Gains in both engines were made via tweaks to the engine design and by adding the same VarioCam Plus technology that’s used in the Porsche 911 and Porsche Cayman S. VarioCam Plus is like having a miniature accountant in the engine. He’s constantly monitoring airflow and making adjustments to the cams and valves to insure there’s no waste and that maximum power is the bottom line. The most enjoyable benefit of this improvement is the engine’s broad torque band and its ability to deliver maximum power all the way from 4,600 rpm to 6,000 rpm.
