370Z Engine Specifications

The 370Z comes equipped with an all Aluminum 3.7L displacement 24 valve double overhead cam (DOHC)V6. It is Named by nissan the VQ37VHR.

It comes with a new Variable Valve Event and Lift (VVEL) and Continuously Variable Valve Timing Control System (CVTCS)as seen below.

While conventional engines control air intake using a throttle valve, VVEL-equipped engines do this directly at the intake valves, continuously controlling their valve events and lifts.

In the VVEL system, a rocker arm and two types of links close the intake-valves by transferring the rotational movement of a drive shaft with an eccentric cam to the output cam.

The movement of the output cam can be varied by rotating the control shaft within the DC motor and changing the fulcrums of the links. This makes a continuous adjustment of the valve lift amount possible.

The VVEL improves fuel efficiency most effectively in the low-to-medium operating range, thus it is best matched to the multiple-cylinder and higher displacement engines, that typically operate within that range.

C-VTC and VVEL together control the valve phases and its valve events and lifts, allowing free-control of the valve timing and lift.

This results in more efficient airflow through the cylinder and significantly improves responsiveness, optimising the balance between power and environmental performance.

With the VVEL and CVTCS on the new 370z, The power increases to 332 hp @ 7000 rpm with 270 ft-lbs. @ 5200 rpm running on premium unleaded fuel.
