Comprehensive running tests

Driving in locations around the world to refine quality for the benefit of our customers globally

There are four main phases to creating and supplying a vehicle: planning, development, production and marketing/sales. Our running tests are conducted during the two middle stages. We use a factory test car during development, and then a mass-production test car during production. We address the issues that emerge during the development stage immediately, before the car reaches the mass-production test car stage. We then confirm that the final quality standards have been met. The running tests performed during these two stages are all conducted in the regions where the vehicles will be marketed and sold. Meticulous efforts are made to ensure that Nissan vehicles suit local conditions.

Double-checking quality from data and driver feedback evaluation

We run rigorous, repetitive, high-precision tests over a short period, in some instances driving the cars for 24 consecutive hours or more. At Nissan, we refer to these systematized local running tests as PSQC* tests. Our test drivers conduct thorough checks on handling, drivability, engine noise and various other aspects from a critical perspective, evaluating all matters related to the customer’s driving experience. The data collected helps us to determine whether the vehicle meets the quality targets set.

  • PSQC stands for Pre SOS Quality Clinic. This is Nissan’s original quality inspection system, which includes running tests conducted under the regional road and environmental conditions our customers will encounter.

Thoroughly refining quality to withstand both scorching heat and extreme cold

Virtual running tests are conducted to check quality under more severe conditions that are difficult to reproduce in a real environment. Our testing facilities and plants have environmental test chambers that can reproduce the heat, humidity and road conditions found in any region of the world. For example, vibration can be applied to simulate the rough, unpaved roads found in certain markets. We can evaluate the impact on the vehicle’s handling or riding comfort and the deterioration of components from heat or humidity as well. At Nissan, actual and simulated running tests are repeated to ensure our customers can truly feel that Nissan vehicles are good vehicles. We strive to improve all-out quality.
