2026 Lexus IS Body Structure

2026 Lexus ES

The Lexus 2026 ES rides on an updated version of the TNGA-K platform, which supports both hybrid and electric powertrains. This platform incorporates ultra-high-tensile steel in critical areas to improve crash safety and structural integrity. The vehicle’s longer wheelbase and increased dimensions likely required additional structural bracing, which may include hot-stamped steel in load-bearing zones. The Lexus ES also includes aluminum components in non-structural areas (like the hood or suspension arms) to balance strength and efficiency.

Underneath the sheet metal sits a heavily reworked GA-K architecture that can package either an internal-combustion engine or a sizable under-floor battery pack. Below is that battery pack.
