McLaren GTS 嘅乾重只有 1,456 kg，比 GT 再輕 10kg。輕量化主要來自 MonoCell II-T 碳纖維單體殼底盤，呢個底盤係 McLaren 嘅核心技術，兼顧咗輕量化同高剛性。車身淨重控制得非常好，係同級入面最輕嘅 GT 超跑之一。
The McLaren GTS has a dry weight of just 1,456 kg, 10 kg lighter than the GT. The weight saving is primarily due to the MonoCell II-T carbon fibre monocoque chassis, a core McLaren technology that balances lightweight construction with high rigidity. This makes the GTS one of the lightest GT supercars in its class.
