You’ve surely heard about the Volvo XC90 Excellence plug-in hybrid, haven’t you? It is powered by a 2.0-litre petrol engine and an electric motor. This Volvo plug-in hybrid can be driven for over 20km without consuming a drop of fuel. The batteries are rechargeable, and when they go dry, the SUV runs on petrol. It costs Rs 1.275 cr in India. The Volvo XC90 is also available with a diesel engine, and that costs Rs 95 lakh. If the plug-in hybrid version was taxed at 10 per cent instead of 43 per cent (as both diesel and hybrid in the existing case), the price difference between the diesel and the hybrid XC90 would come down to around Rs 3 lakh, the hybrid still being the more expensive of the duo. The hybrid XC90’s sales are about 5 per cent of the total sales of the XC90 model in India, and the biggest deterrent has to be the over-Rs 30 lakh price difference.
