At CES in Las Vegas, Asus has announced a new model of the Zenbook 13 which now weighs just 985 g (~2.17 lb) despite an increase in battery life. This really reminds us of the Gram notebooks from LG.

Many details on the lightweight device are not known yet. However, if we can find out more at CES, we will add it as an update below. Asus has introduced the Zenbook 13 with the UX331UN model number at IFA 2017 in Berlin. At that time, the weight was 1.12 kg (2.47 lb) and the battery life of the integrated 50 Wh battery was estimated by Asus at 14 hours. Even then, it featured an Intel quad-core processor of the Kaby-Lake U series with up to 16 GB of RAM and a 1 TB SSD.

The 13.3-inch NanoEdge display was available in Full HD or UHD resolution, and optionally an Nvidia MX150 GPU was integrated. Now at CES 2018, the slightly changed UX331UAL model follows, which thanks to its reduced weight can now directly compete against the Gram notebooks from LG. Its 13 and 14-inch notebooks also weigh less than 1 kg (2.2 lb). We were unable to ascertain from the press release how exactly Asus achieved the reduction in weight by more than 100 grams.

Here Asus only mentions the 15-hour battery life, the quad-core processors of Intel's 8th generation, and a maximum of 16 GB of RAM and a 1 TB SSD. This is accompanied by a sound system by Harman Kardon and modern Windows technologies such as Windows Hello via fingerprint sensor. In the pictures, you can see a conventional power connection, HDMI, two USB Type-A ports and one USB Type-C connection, which according to the logo does not offer Thunderbolt 3 though. With this in mind, the looks of the new model do not differ that much from the predecessor. Asus did not specify anything on pricing and availability.
