The 2021 HMI UX Benchmarking Report Summary has been created to provide a fair, unbiased and objective view of the latest in-vehicle HMI solutions in the European, US and Japanese markets. Evaluations are carried out by SBD usability experts with a deep understanding of CASE domains, specifically the Connected Car and ADAS & autonomy domains.

The following vehicles were evaluated as part of the 2021 Series – Mercedes-Benz S-Class, CUPRA Formentor, Tesla Model S, Hyundai IONIQ 5, Lexus LS, Cadillac Escalade, BMW iX and Nio ES8.

SBD’s HMI UX Evaluation Report Series provides a comprehensive assessment of the latest systems released globally. Over the course of 2021, our team of HMI and UX experts benchmarked eight vehicles from Europe, the US, 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.
