Aug 20 (Reuters) - Chinese firm XPeng ( XPEV )

forecast third-quarter revenue below expectations and missed

June-quarter sales estimates on Tuesday, hurt by stiff

competition and a drop in demand for its aging line-up of pricey

electric vehicles.

The company, however, expects to deliver between 41,000 and

45,000 vehicles in the third quarter, slightly above 40,008

units a year earlier.

XPeng's ( XPEV ) Hong Kong-listed shares fell 2.7% on Wednesday.

The company is planning to refresh its model lineup by

launching a range of new EVs in the next three years, priced

between 100,000 yuan and 400,000 yuan ($14,001.88-$56,007.51),

to grab market share from rivals like BYD, Nio

and U.S. automaker Tesla.

It plans to launch the MONA M03 mid-sized sedan this month,

which is set to compete with BYD's Seagull, Dolphin and the

higher-priced Tesla Model 3.

XPeng ( XPEV ) has seen its expansion plans temporarily throttled by

the European Commission's move to impose tariffs on electric

vehicles made in China to prevent a flood of cars built with

state subsidies.

It is among the Chinese companies considering setting up a

manufacturing plant in the region to avoid those tariffs.

Vehicle margin in the April-June period improved to 6.4%

from 5.5% in the prior quarter. It expects to deliver between

41,000 and 45,000 vehicles in the third quarter, compared with

40,008 units in the corresponding quarter of last year.

XPeng's ( XPEV ) revenue rose to 8.11 billion yuan ($1.14 billion),

in line with its forecast of 7.5 billion and 8.3 billion yuan,

but slightly below analysts' average estimate of 8.17 billion

yuan according to LSEG data.

It expects third-quarter revenue between 9.1 billion yuan

and 9.8 billion yuan, compared with analysts' estimates of 10.4

billion yuan.
