The Aston Martin DBX707 features several major upgrades to its powertrain. It is equipped with a 9-speed wet-clutch automatic transmission (9-speed MCT) sourced from Mercedes-AMG, replacing the traditional automatic gearbox in the standard DBX for faster and more direct gear changes. Additionally, the DBX707's air suspension reservoirs have been enlarged three-fold, and it features a new eARC (Electronic Active Roll Control) system, significantly enhancing handling stability. The DBX S further incorporates turbocharging technology from the Valhalla for even sharper response.
Aston Martin DBX707 喺動力系統上有幾項重大升級。DBX707 改用咗源自平治 AMG 嘅 9 前速濕式離合器自動波箱（9-speed MCT），取代標準版 DBX 嘅傳統自動波箱，換檔速度更快更直接。同時，DBX707 嘅電子氣壓避震儲氣樽擴大咗三倍，並加入全新 eARC 電子主動式防傾桿系統，大幅提升操控穩定性。DBX S 進一步導入 Valhalla 嘅渦輪增壓技術，引擎響應更敏銳。
