Citroën took advantage of this week's election of a new Pope to promote its clean diesel initiatives. The advertisement in the video below shows one determined Citroën engineer as he climbs atop the Vatican to take care of a pesky black smoke problem. After he works his magic, the famous chimney starts puffing out white smoke instead. We would think a clean diesel would yield no smoke at all, but hey, that's just us. We will say the opportunistic commercial is at least good for a chuckle. You can check it out in the ad below.
The French automaker unveiled a number of vehicles at the Geneva Motor Show earlier this month, including the updated 2013 C3 shown below. The five door can be had with a spate of engine options, including at least four clean diesel options with power ranging from 70 to 115 ponies.
