Lenovo has announced that it has added the ThinkPad X1 Carbon Touch to its range of Windows 8-optimised Ultrabooks. The 14in Ultrabook improves on the ThinkPad X1 Carbon by adding a touchscreen display.

"Bringing touch gesture control to our best ThinkPad ever is a natural evolution of the portfolio and a big step towards fulfilling our promise to bring computers into a new PC+ era," said Peter Hortensius, president of the Lenovo Product Group.

"We are excited to be able to offer customers the best experience in a thin and light business class Ultrabook. The X1 Carbon Touch is the Ultrabook to beat," he added.

Weighing in at 1.5kg and with a thickness of 20.8mm, the ThinkPad X1 Carbon Touch is the world's lightest 14in Touch Notebook, according to Lenovo. The firm attributes the model's sleeklness to the chassis, which is made from lightweight carbon fibre.

Other features include a 1.8GHz Intel Core i5 processor, 8GB of RAM and an HD+ display with 10-finger touch capability.

The ThinkPad X1 Carbon Touch will retail for £1,525 (excluding VAT) from January 2013.
