For enthusiasts eagerly anticipating a comprehensive review of the 2023 Nissan 370z, discussions would typically revolve around its road prowess, expansive visibility, and a design that cleverly blends generations of Z-car heritage. However, this evaluation takes a different turn, focusing squarely on track performance, which unfortunately begins with a note of disappointment.
Our test model, a Nissan 370Z Performance trim, seemed ideally equipped for track scrutiny. It boasted 19-inch Rays wheels, a mechanical limited-slip differential, robust brakes, and the coveted six-speed manual transmission. Priced at $53,210 and delivering 400 horsepower, the 370Z appeared to be a direct competitor to the Toyota Supra, positioning itself above models like the Toyota GR86 and Subaru BRZ in terms of sheer power and price.

With a full tank of gas, our Nissan 370Z Performance weighs 3274 pounds.
To rigorously assess its capabilities against competitors, we subjected the new Nissan 370Z to the demanding conditions of the Florida International Rally & Motorsport Park, GRM’s designated test circuit. The weather was predictably sunny and warm, typical for the region, providing consistent conditions for our track analysis.
Initial Track Impressions: Competent but Cautious
Our initial laps in the Nissan 370Z revealed a car that performs admirably up to approximately 80% of its limit. The steering feel is communicative, sightlines are excellent, and the power delivery is notably flexible. Drivers can easily visualize their intended path and confidently guide the car.
One standout feature of the Nissan 370Z is its exceptional trail-braking capability into corners. The braking system is remarkably potent, responsive, and inspires confidence. It effectively manages speed reduction while providing reassuring feedback, even when the ABS engages. In slower to medium-speed corners, the 370Z’s braking instills the assurance needed to brake deeply and precisely.

High-Speed Handling Concerns: Nervousness at the Limit
However, as speeds escalate, the initial confidence begins to wane. The Nissan 370Z exhibits nervousness and lacks the planted feel expected from vehicles in its class when pushed harder.
We attribute a significant portion of this issue to what appears to be an under-sprung chassis. This setup results in slow weight transfer, delaying the car’s ability to settle into a set position through corners. While this delay is often manageable with responsive tires that provide feedback on weight transfer, the 370Z’s throttle response complicates matters.
The throttle application is characterized by a logarithmic curve, delivering a surge of power in the final few degrees of pedal travel. This characteristic becomes problematic, particularly when exiting medium-speed and slower corners. As the chassis finally begins to settle and weight shifts rearward during corner exit, modulating the throttle becomes critical.
The challenge lies in synchronizing the chassis setting with the engine’s power delivery. There’s a critical moment when the rear stabilizes, full throttle is applied, and the engine unleashes more power than the chassis can effectively handle. This imbalance leads to wrestling with the rear end to prevent breakaway, highlighting a mismatch between the throttle responsiveness and chassis dynamics.
While the 370Z maintains composure in slower, heavily loaded turns, a pervasive nervousness and imprecision become apparent when trail-braking into higher-speed entries. In these demanding conditions, competitors like the Supra, BRZ, and the latest Honda Civic Si offer a more secure and predictable feel.
At its performance limits on the track, the Nissan 370Z can feel like a demanding, white-knuckle experience—at least in its factory configuration, consistent with how we evaluate other new vehicles.
Data Analysis: Lap Times and Dyno Results
What do the performance metrics reveal? Remarkably, the data traces for the Nissan 370Z closely mirror those of the latest Subaru BRZ. Lap times corroborate this observation, with the automatic-equipped Subaru BRZ clocking in at 1:23.16, and our Nissan 370Z test car achieving a 1:23.44.

In contrast, the Toyota Supra outperforms both, recording a lap time of 1:19.59 while exuding greater confidence and stability.

Speed analysis further illustrates the Nissan 370Z’s somewhat subdued acceleration, aligning closely with the BRZ and significantly trailing the Supra.
To investigate potential power deficiencies, we conducted dyno tests at BSI Racing. Our measurements peaked at 353 horsepower and 360 lb.-ft. of torque. Considering driveline losses, these figures are reasonably aligned with the engine’s advertised 400 horsepower rating.

However, it’s worth noting that Z Car Garage reported a higher output of 379 horsepower in their dyno testing. Discrepancies could stem from correction factors (SAE at BSI Racing versus standard at Z Car Garage) or variations between dyno equipment. Nevertheless, our three consecutive dyno runs produced consistent results.

The Verdict: Untapped Potential for the 2023 Nissan 370Z
While our track testing reveals that the 2023 Nissan 370Z, in its factory form, doesn’t quite match the track prowess of some competitors, particularly at higher speeds, it is far from a failure. Instead, it presents an intriguing platform ripe with untapped potential. We are particularly keen to observe how aftermarket modifications can unlock greater performance from the 370Z. Addressing the suspension and throttle mapping could significantly elevate its track capabilities, transforming it into a more formidable and balanced sports car. The robust engine and braking system already provide a solid foundation for enthusiasts looking to enhance their 2023 Nissan 370Z’s track day performance.
