Mercedes-Benz has launched the new C-Class Cabriolet in India with updated features, new colours and, more importantly, a new BSVI-compliant petrol engine that can also run on BSIV fuel. It’s also the first Mercedes-Benz petrol engine in India that conforms to BSVI standards while being capable of running on BSIV fuel. Earlier in 2018, BMW had upgraded all petrol engines in its lineup to BSVI standards.
