Mercedes-Benz won't officially confirm anything, photos of the updated 2011 C-Class have now surfaced -- at least for a brief time -- on both its German and UK websites. As this image shows, the mid-cycle refresh is a pretty subtle tweaking exercise. The most obvious change can be seen at the front of the car, with the fitment of new LED-style running lamps in what appears to be a very modestly recontoured soft fascia. Expect this low-level recasting to endow the C-Class with several new premium touches in its passenger cabin, including the automaker's recently announced "mbrace" telematics package that supplants the existing Tele Aid system and brings a host of upgraded features, wireless connectivity and a whole new level of user-friendliness to the mix. We suspect that the biggest change to the 2011 C-Class may well come underhood, with the likely addition of M-B's new four-cylinder BlueTec turbodiesel. Originally shown in the Vision C220 BlueTEC concept vehicle that first appeared at the 2007 Geneva Auto Salon, this super-clean 2.2-liter motivator makes 170 horsepower but a stout 295 lb.-ft. of torque.
