Nissan’s VC-Turbo engine offers any compression ratio between 8:1 for high performance and 14:1 for high efficiency. The engine delivers 248 horsepower 5,600 rpm and 273 lb-ft of torque 4,000 rpm (premium fuel).

The VC-Turbo’s specific power output is higher than many competing turbocharged gasoline engines and comes close to the performance of some V6 gasoline engines. The unit’s single-scroll turbo ensures immediate accelerator responses on demand.

Along with the world’s first multi-link system, the engine features an electric motor with a unique Harmonic Drive reduction gear to manage the variable compression ratio.


The electric motor is connected to the Harmonic Drive with a control arm. As the Harmonic Drive rotates, the control shaft at the base of the engine rotates, moving the multi-link system within the engine.
