I have to assume that i can not read anything in Mandarin and google translator didn't really help, all i know is that the S80 (S80L) will have a slight face-lift for 2013 (atleast in China), causing it to reach 9 years of life instead of a life cycle of 8 years, normal in Volvo.
But we can understand why it reached the 9 years. Volvo just finished the development of the new VEA (Volvo Environmental Architecture) platform and the new engine family, so they wouldn't do such a major change to a model one year, using older parts and technologies, then debut a new set of components in the following year and have it stay in the market for a long time already outdated.
The alterations made are small, the bumpers are a little different, so is the exhaust pipe and the rearview mirrors, there is also new wheels available, new chrome trims, an updated grille with new headlamps that now include LEDs with some other minor changes to the body. Volvo will also drop the 2.0liter engine from Ford.
Still that front bumper reminds me of something out of Volkswagen...
