About this report

In this edition, the UX team is testing the Peugeot 408 GT.

The Peugeot 408 returns a strong score for user experience, finishing middle of the pack compared to 2022 and 2023 vehicles, but achieves a disappointing score of C+ for functionality finishing equal to the lowest ranked vehicle for functionality in 2022 and lowest overall in 2023.

SBD’s HMI UX Evaluation Report Series provides a comprehensive assessment of the latest systems released globally. Over the course of this year, our team of HMI and UX experts will benchmark six vehicles from Europe, the US, China, and Japan to understand who is leading in the space, and who is falling behind. Each report helps provide an indication of what the final customer experience of each vehicle should be. In doing so, the team thoroughly scores and analyses them across several HMI domains.

These include the vehicle’s ADAS, infotainment, navigation, voice recognition, connected feature, and convenience capabilities. Our experts assess the reliability of each domain - testing their repeated usability, evaluating whether their solutions provide the features that customers expect and need, and gauging how easy these features are to learn. Likewise, the potential perceived quality of individual HMI components is measured against its impact on the overall customer experience.


Features and functionality: Evaluating whether the solutions provide features that customers expect, need and solve problems (or provide a wow factor).


Usability: Evaluating whether the features available are easy to learn and use. This considers areas such as ergonomics, legibility, usability characteristics and how the system implements the various features.


Reliability/stability: evaluating the repeated usability and whether the users can have a similar (positive) experience each time.

Key Scoring Areas


Perceived quality: evaluating the potential perception in quality of the HMI components and how this contributes to the overall customer experience.
