Driving the Toyota Glanza in hilly areas should not be a problem as long as you drive it with care. Driving in the hills can be tricky but if you’re careful with your vehicle and treat it right it will still behave very well. Also, since Glanza is a front-wheel-drive it is very comfortable in hilly regions but it would be slightly underpowered when it is packed with four people and luggage. In terms of mileage, overall there should be a slight difference. On average in normal circumstances the car delivers around 20kmpl with its petrol version and around 26kmpl in diesel. The car has a ground clearance of 170mm. The seats do have good support for the back, to have a comfortable drive. Moreover, you may have a test drive of the car for a better idea of comfort and drive quality by visiting the nearest dealer in your city - Dealers.
