Official information is now out. NDRC has approved both the F600 and F600L (LZ6470MQ15M, LZ6510MQ15M).
The dimensions are (L/W/H/WB) 4740/1770/1915/2900 mm for the F600 and 5080/1770/1915/3200 mm for the F600L. Unladen weights are 1670 kg and 1780 kg. Engine is 1499 cc/110 kW.
So these two are in fact derivatives of the CM7, and not a renamed CM7. The CM7 in its current spec is slightly longer (5150), wider (1920), significantly heavier (1980-2120 kg) and has larger displacement engines (1997/2378 cc).
