March 19 (Reuters) - Chinese electric-vehicle maker

Xpeng ( XPEV ) forecast first-quarter revenue below

market expectations on Tuesday as a sluggish economy and stiff

competition weighed on vehicle demand.

The company expects first quarter revenue between 5.8

billion yuan ($805.67 million) and 6.2 billion yuan, compared

with estimates of 11.37 billion yuan, according to LSEG data.
