LG has unveiled its new Gram laptop lineup, and at its heart sits the LG world's lightest 17-inch laptop ever made — a bold claim backed by aerospace-grade materials and cutting-edge AI features. Announced ahead of CES 2026, the new Gram series raises the bar for portable computing with its next-generation Aerominum construction and deep integration with Microsoft's Copilot+ PC platform.
- LG's new Gram lineup includes the world's lightest 17-inch RTX laptop, the 17Z90UR, built with Aerominum — an aerospace-inspired magnesium-aluminum alloy.
- The range spans six models across 14, 15, 16, and 17-inch sizes, all featuring on-device AI capabilities without requiring an internet connection.
LG World's Lightest 17-Inch Laptop: The 17Z90UR
The headline model in the new lineup is the 17Z90UR — the world's lightest 17-inch RTX laptop. It sports a large 17-inch WQXGA display with a resolution of 2,560 x 1,600 pixels, giving users ample screen real estate without the usual weight penalty. Under the hood, it is powered by an NVIDIA GeForce RTX 5050 Laptop GPU paired with 8GB of GDDR7 RAM, making it a capable machine for both creative work and everyday productivity. The 17Z90UR has been launched exclusively for the North American market.
The secret behind its record-breaking weight lies in Aerominum, a proprietary alloy of magnesium and aluminum developed using aerospace-inspired technology. LG claims the new material not only reduces weight compared to previous Gram generations but also improves overall durability — a common concern with ultra-light laptops.
LG Gram Pro AI Features and Full Lineup
The full Gram 2026 family covers a wide range of use cases. The LG gram Pro AI is available in both 16-inch and 17-inch configurations, while the LG gram Pro 360 AI offers a 2-in-1 convertible form factor in a 16-inch size. Rounding out the range are the gram AI and gram Book AI, which come in 14 and 15-inch sizes for users who prioritize compactness.
All models in the lineup support Microsoft Copilot+ PC, LG's own LG gram Chat, and the EXAONE 3.5 sLLM — an on-device small language model that delivers private AI assistance without needing an active internet connection. This means users can leverage intelligent features even in offline environments, a significant advantage for travelers and professionals on the move.
The 16Z90U: Most Portable Dual AI Laptop
Another standout in the lineup is the 16Z90U, LG's most portable dual AI laptop. It features a premium 16-inch WQXGA+ OLED display at 2,880 x 1,800 pixels, delivering vibrant colors and deep contrast for content creators and professionals. The device is powered by an Intel Core Ultra processor, designed to handle demanding workloads while keeping battery consumption in check. LG positions the 16Z90U as an excellent productivity machine for users who want a balance between performance, display quality, and portability.
Durability and Build Quality
LG has consistently marketed the Gram series on its combination of light weight and military-grade durability, and the 2026 lineup continues that tradition. The Aerominum material is designed to offer greater rigidity and resistance to everyday wear compared to the materials used in earlier Gram models. While LG has not published specific MIL-SPEC test details for these new models at this stage, durability improvements remain a core part of the product story.
