The Subaru Solterra and Toyota bZ4X are "sister cars," sharing the same eTNGA platform, battery, and motors. The key difference is that the Hong Kong Solterra has dual-motor AWD (the bZ4X has single-motor front-wheel drive), plus the Solterra adds X-Mode and Grip Control with higher ground clearance for better off-road capability. Additionally, the Solterra's instrument cluster is uniquely positioned at the base of the windscreen.
Subaru Solterra 同 Toyota bZ4X 係「兄弟車」，共享相同嘅 eTNGA 底盤、電池同摩打。最大分別係 Solterra 香港版雙馬達四驅（bZ4X 係單馬達前驅），而且 Solterra 多咗 X-Mode 越野系統同 Grip Control，離地間隙亦更高，越野能力更強。另外，Solterra 錶板位置設計比較特別，喺擋風玻璃底部。
