Spy shots showing the Citroen CS5 sedan testing in China with a 1.6 turbo under the bonnet. The new engine is expected to debut on the Guangzhou Auto Show in November and it will be launched on the China car market just before the end of this year.

The Citroen C5 is made in China by the Dongfeng-PSA joint venture. Price starts at 176.900 yuan and ends at 298.900 yuan. Power comes from three: a 2.0 with 147hp, a 2.4 with 171hp, and a 3.0 V6 with 220hp.

The 1.6 turbo delivers 163hp and 240nm, mated to a six-speed automatic. As for now the new engine is an addition to the line-up, not a replacement. Many Chinese car buyers still prefer bigger engines because big = good, no matter if they use more petrol and make the world a yet dirtier place.
