What is the mileage of Mahindra XUV300 deisel AMT compared to manual, which will be the better option?

Both BS6-compliant 1.2-litre turbocharged petrol engine and a 1.5-litre diesel unit engines are offered with a 6-speed manual transmission while the diesel engine is available with an AMT gearbox as well. The ARAI claimed mileage of 1.5-litre diesel AMT is 20.0 kmpl. If you are travelling is less than 60km a day, opt for a petrol car instead of diesel. A diesel usually makes sense if you are driving above 60/70km a day. If you'll be driving more in heavy city traffic then we suggest you to opt for Automatic Transmission which are easier to use and more comfortable for the driver, while Manual Transmission vehicles are less expensive more involved
