Fuel economy is not determined by the engine alone. The way a car is driven every day can also influence how much fuel it uses. A vehicle that spends most of its time in congested city traffic will have a different fuel consumption pattern from one that regularly travels on open roads. Similarly, frequent hard acceleration, unnecessary idling and repeated braking can affect how efficiently fuel is used.
This is worth keeping in mind when looking at figures such as Sonet mileage. The number associated with a vehicle is useful for comparison, but actual fuel consumption depends on several conditions, including the engine, transmission, traffic, road conditions, load and driving habits.
The current vehicle referenced on the manufacturer’s website is offered with three engine choices: a 1.0 T-GDi petrol engine producing 88 kW and 172 Nm, a 1.2 petrol engine producing 61 kW and 115 Nm, and a 1.5 CRDi VGT diesel engine producing 85 kW and 250 Nm. Multiple transmission options are also available.
Why City Traffic Can Increase Fuel Consumption
City driving involves constant changes in speed. A driver may accelerate after a traffic signal, slow down for a pedestrian, stop behind another vehicle and then move again within a few seconds.
This stop and go pattern can use more fuel than maintaining a steady speed. Every time the vehicle moves away from a standstill, the engine has to provide the power needed to get the vehicle moving again. When this happens repeatedly throughout a journey, fuel consumption can rise.
Traffic congestion also creates another problem. A vehicle can spend considerable time with the engine running while covering very little distance. A 10 kilometre commute, for example, may take longer during peak traffic than when the same route is clear.
This is why two drivers travelling the same distance can record different fuel economy figures.
The Effect of Frequent Acceleration
Acceleration is a normal part of driving, but how it is done matters.
Pressing the accelerator aggressively to move quickly from every traffic signal can increase fuel use, particularly when the driver soon has to slow down again. A more measured increase in speed can be sufficient when traffic is moving normally.
Consider a common city driving situation. The traffic light turns green, the driver accelerates sharply, reaches a high speed and then notices that vehicles ahead have stopped. The brakes are applied and the vehicle slows down. A few moments later, the process begins again.
Some of the energy used to build speed has effectively been lost during braking. Repeating this pattern throughout a journey can make the drive less fuel efficient.
Smooth acceleration is therefore not about driving unnecessarily slowly. It is about matching acceleration to the traffic around you.
Looking Ahead Can Reduce Unnecessary Braking
Good observation can make a difference to fuel economy as well as driving comfort.
If a driver can see that traffic ahead is slowing, easing off the accelerator early may sometimes reduce the need for heavy braking. Similarly, if a red traffic signal is clearly visible ahead, there may be little reason to accelerate aggressively towards it.
This does not mean drivers should avoid braking when required. Traffic conditions can change suddenly, and safe control of the vehicle should always come first.
The objective is to avoid creating unnecessary speed changes when the road situation is already predictable.
Idling Uses Fuel Without Adding Distance
Idling is easy to overlook because the vehicle is not moving. However, when the engine is running, fuel is still being consumed.
Waiting outside a shop, sitting in a parking area with the air conditioner running or remaining stationary for a prolonged period with the engine switched on can add to fuel consumption without increasing the distance travelled.
The current vehicle includes an Idle Stop and Go system on specified variants, designed to help reduce unnecessary engine running during suitable stops. The feature is particularly relevant to urban driving, where vehicles may spend considerable time stationary in traffic.
However, drivers should not treat every short pause as a reason to switch the engine off manually. The practical approach is to avoid unnecessary prolonged idling while allowing the vehicle’s systems to operate as intended.
Traffic Conditions Matter More Than a Single Mileage Figure
It is tempting to compare a vehicle’s fuel economy with a single figure and expect the same result on every journey. Real-world driving does not work that way.
A driver travelling at a steady speed on an open road may achieve a different result from someone covering the same distance through crowded streets. Road gradients, traffic signals, road quality, weather, vehicle load and air conditioning use can all influence consumption.
The manufacturer’s current information describes the vehicle as being available with fuel efficient engine options and multiple transmission choices.
Transmission type can also influence how the car behaves in traffic. Drivers using a manual transmission have direct control over gear selection, while automatic variants manage gear changes according to driving conditions and system inputs. The available combinations vary by engine and variant, so fuel consumption should be considered in the context of the version being driven.
Smooth Driving Does Not Mean Slow Driving
There is a common misconception that improving fuel economy means driving extremely slowly. That is not necessarily the case.
A smoother driving style is more about consistency than speed. Where road and traffic conditions permit, maintaining a steady pace can be preferable to repeatedly accelerating and braking.
For example, if traffic is moving at a consistent speed, there may be little benefit in repeatedly changing lanes, accelerating past other vehicles and then braking because the traffic ahead has slowed.
A calm approach allows the driver to respond to traffic instead of constantly reacting to it.
Short Journeys Can Affect Fuel Economy
Daily errands can create a different fuel consumption pattern from longer journeys.
A typical day might involve driving a few kilometres to work, returning home, making a short trip to the market and then travelling somewhere else in the evening. Each trip involves starting the vehicle and dealing with local traffic, signals and parking.
By comparison, a longer journey may involve a greater proportion of steady-speed driving.
This does not mean that short journeys are inherently bad for a vehicle or that drivers should avoid them. It simply explains why the fuel economy recorded during repeated short city trips may differ from figures seen during longer drives.
When tracking Sonet mileage, it is therefore more useful to observe fuel consumption over several refuelling cycles rather than judging it from one particularly congested trip.
Air Conditioning and Other Factors Also Play a Role
Driving behaviour is only one part of fuel economy.
Air conditioning can influence fuel consumption, particularly when it is used heavily in hot weather. Carrying unnecessary weight, driving on steep inclines and travelling through poor road conditions can also affect how much effort the vehicle needs to maintain movement.
Tyre condition matters as well. Keeping tyres at the recommended pressure helps ensure that the vehicle operates as intended. Regular servicing is equally important because the engine, transmission and other mechanical components need to remain in proper working condition.
The manufacturer’s website also highlights the vehicle’s maintenance and total cost of ownership, noting that its stated ownership-cost assessment includes maintenance, fuel, insurance, finance and other factors.
Everyday Habits That Can Help
Drivers who want to make their daily journeys more fuel conscious can start with a few simple habits:
- Accelerate progressively when traffic conditions allow.
- Avoid racing away from traffic signals only to brake moments later.
- Look ahead and anticipate changes in traffic.
- Maintain a consistent speed where appropriate.
- Avoid prolonged unnecessary idling.
- Keep tyres correctly inflated according to the recommended pressure.
- Remove heavy items that do not need to remain in the vehicle.
- Follow the recommended maintenance schedule.
- Use air conditioning sensibly, particularly during extended stationary periods.
- Monitor fuel consumption over several journeys rather than relying on one reading.
None of these habits requires a major change to the way a person drives. They are mostly about becoming more aware of what is happening around the vehicle.
Conclusion
A vehicle’s fuel economy is best understood in the context of its regular use. Someone who drives mostly through crowded urban roads should not expect the same consumption pattern as someone who spends most of their time on open highways.
The same principle applies when evaluating Sonet mileage. Engine and transmission selection provide an important starting point, but everyday conditions determine how the vehicle is used.
For someone considering vehicle financing, this is also a practical part of ownership budgeting. Fuel is a recurring expense, alongside the monthly loan EMI, insurance, servicing and other running costs. Understanding how driving habits affect consumption can therefore help create a more realistic picture of regular car expenses.
Traffic cannot always be avoided, and sudden braking cannot always be prevented. What drivers can control is how they respond to ordinary road conditions. Reducing unnecessary acceleration, limiting prolonged idling and maintaining smoother changes in speed can make everyday driving more measured while helping drivers keep a closer eye on their fuel consumption.
