Some news about GM’s sub-brand Baojun – the 630 sedan, which was launched last year in five-speed manual form, gets new model variants for 2012. Seen in Beijing were the new 1.5 litre P-Tec DVVT AT, as well as a 1.8 litre AT version.

The 1.5L AT was actually launched earlier in the month, on April 12, but is making its show debut at Auto China. Pricing for the six-speed AT variant is 78,800 Yuan to 85,500 Yuan, as indicated in the release picked up at the show.

Performance-wise, the Euro IV-compliant 1.5 litre mill offers 110 hp at 5,800 rpm and 146 Nm of peak torque at 3,600 to 4,000 rpm (at 4,000 rpm, in the case of the manual), with a top speed of 170 km/h (add 5km/h to that for the stick shifter version).

As for the 1.8L model, the variant is set to be formally launched later this year, though not details are yet specified, save that the DVVT mill will also be mated to a GM six-speed GF6 series integrated manual-automatic transmission.

The 4.59 metre-long sedan – which sits on a Buick Excelle platform – has been doing pretty well since its introduction; the manual version managed to bag sales of over 9,000 units in its first month, and sales for the first quarter of 2012 have totaled 22.035 units.
