「セレナ」をベースにした実験車両で、従来実験車両「リーフ」に対し性能向上したカメラ、レーダー、ライダーを採用。ルーフに搭載されたセンサーは、セレナの全高活かし検出エリアを広げながらより高精度検出可能とした。

AIを活用した車外環境認識行動予測による判断制御機能進化。よりスムーズな走行可能となった。ルート上で遭遇しうるさまざまなシーンを検証しながら、冗長性もたせたシステム構成とし、異常時の即時停車機能を持つ。これにより、車内運転者がいない状況でも安全性確保される。

日産は、2017年度から自動運転モビリティサービスの実証実験行なっており、2025年度下期から2026年度にかけて、横浜市20台を運用する大規模なサービス実証実験実施を予定。現在は、関連事業者運営体制とサービスエコシステムの構築進めている。2027年度には自治体や交通事業者などの関係者協議し、遠隔監視設備備え自動運転レベル4によるモビリティサービスの提供目指す
