Spotted this Volkswagen Virtus, local sedan derivative of the current generation of the Polo, the first one I saw in my hometown taxi livery.

I'm more used to CNG-converted cars, which retain their original fuel tank, and it's often recommended to start on gasoline and leave it reach its operating temperature before switching fuels even though CNG could be supposed to lead to an easier cold start because it's already injected in vapour phase. A few cars fitted with a CNG system from the factory (or from a certified installer through dealer order) such as a local version of the Opel Astra B released in 2006 were set to start on CNG.
