VarioCam Plus.
Enter VarioCam Plus, the latest evolution of our patented variable valve timing system. Each cylinder’s intake and outlet valves now feature dual springs to ensure reliable operation under the higher counter-pressure of the free-revving Turbo S engine. A variable valve lift mechanism has been combined with axial adjustment of the intake camshaft to enable variable valve opening and closing times. In essence, VarioCam Plus offers two engines in one.
At low speeds, smooth idling is met with reductions in fuel consumption and emissions by lowering valve lift and advancing the timing.
Prod the electronic throttle beneath your right foot, and the system responds in an instant: valve lift is increased for quicker induction, and valve timing is advanced for generous amounts of torque over a broad rpm range with ample power reserves for passing.
The inherent flexibility of VarioCam Plus even optimizes performance during cold starts by reducing exhaust emissions as the engine warms. Controlling the entire sequence with split-second precision is Motronic ME 7.8, a digital engine management system that balances impressive power with impeccable smoothness – proving the Turbo’s and Turbo S’s mind is indeed a match for their muscle.
