You don’t need to be an automobile engineer or a maruti swift engineer to have a good knowledge about VXI AND VDI. I think the below steps will surely help many Swift lovers to decide on VXI or VDI.
Petrol= 11 km per liter mileage
Diesel=15 km per liter mileage
Petrol = Rs 48
Diesel = Rs 37
Petrol more fun on high revs
Diesel fun enough on low revs
More rev = more fuel consumption = higher running cost.
Vdi has a turbo which kicks in at about 1800 RPM that is as close as you can get to feeling NOS in India, so go for Swift VDI
