Two months ago Tata upgraded both Safari and Harrier with facelift changes. Both come with the same architecture and same engine specs but Safari (1825KG) weighs 150 KG more than the Harrier (1675 KG) which I am guessing is due to the bigger size and the added 3rd row. My question is does the bigger weight have an observable effect on the performance (does Safari feel slow slower in terms of acceleration) and mileage (does Harrier give a better mileage) of the vehicle?
