Outputs of 318hp (237kW) and 380Nm are quoted by auto-sina.com.cn, and the V6 engine will be coupled as standard to a 10-speed automatic transmission.
In China, the LS350 is expected to cost around 1 million yuan ($196,530), which should make it substantially cheaper than its twin-turbocharged LS500 sibling, and should put it in direct competition with entry-level Chinese-market limousines like the Mercedes-Benz S320.
No images of the interior have been released yet, though going by the exterior shots from auto-sina.com.cn the LS350 will be available with a similar look inside and out to the LS500 and LS500h.
Lexus's local arm has confirmed the LS350 will not be offered in Australia.
The LS500 and LS500h will come here, though, scheduled to arrive next year.
