According to a document leaked to CarAdvice, the 2018 Nissan 370Z Nismo’s naturally-aspirated 3.7-litre V6 has had the extra outputs liberated with help from an "exclusive H-configured exhaust system design and muffler tuning, along with enhanced ECM (Engine Control Module) calibration".
Nissan Australia announced pricing for the Nissan GT-R Nismo’s baby brother two weeks ago ahead of its launch in September, but is as yet, still to officially announce the model's outputs or any other performance data.
Prices will kick off at $61,490 (before on-road costs) for the six-speed manual and $63,990 (before on-road costs) for the seven-speed automatic.
Thanks to the new performance flagship model’s arrival, the local arm of the Japanese carmaker also dropped pricing across the standard 370Z range by between $4940 and $7440.
The Nissan 370Z Nismo’s now-confirmed outputs are still a fair whack off the impressive 441kW and 652Nm offered up by the twin-turbocharged 3.8-litre V6-powered $299,000 GT-R Nismo.
Subtle as the power hikes may be, buyers can still look forward to a 370Z with a more aggressive body kit, larger brakes, revised suspension, and red exterior and interior highlights, as well as neat 19-inch Rays forged alloy wheels.
