Changes to the coupe's exterior include black door handles and a new rear bumper fascia, while the head and tail-lights get a new dark tint - previously exclusive to the Nismo variant.
Other upgrades include new 19-inch alloy wheels, and a new Red Metallic exterior paint option (pictured).
Meanwhile, manual versions of the 370Z get a new high-performance clutch from performance brand Exedy, which the company says perfects the downshift, thus reducing driver pedal effort.
The 370Z's powertrain remains the same - a 3.7-litre naturally-aspirated V6 lives under the bonnet, producing 245kW of power and 363Nm of torque. Drive is sent to the rear wheels via a six-speed manual or seven-speed automatic with paddle shifters.
However, the flagship 370Z Nismo goes without the 2018 model-year upgrades.
Nissan's local arm is unable to confirm if and when we will see the upgraded 370Z range in Australia at this stage.
However, it would be logical to assume similar upgrades will be applied to Australian models in the near future.
The announcement of this update comes just days after the Australian launch of the 370Z Nismo, which has been on sale overseas for a number of years.
