NEW DELHI: Maruti Suzuki quotes Tour S efficiency at 26.06 km/l for petrol and 34.30 km/kg for CNG. The figures answer different questions because the fuel units differ. For a taxi operator, neither number alone establishes the cheaper shift, the available luggage space or the time needed to complete a duty.
| Verified Tour S fact | Official figure or description |
|---|---|
| Petrol efficiency | 26.06 km/l |
| CNG efficiency | 34.30 km/kg |
| Engine capacity | 1,197 cc |
| Gearbox | 5-speed manual |
| Seating | 5 persons |
| Published top speed | 80 km/h |
| Petrol specification boot volume | 382 litres |
The displayed petrol engine specification also gives 60 kW at 5,700 rpm and 111.7 Nm at 4,300 rpm. Keep those figures attached to petrol when making a comparison sheet. They describe output and torque, whereas the efficiency entries describe distance per quantity of fuel. They are separate measures of the vehicle.
Why the larger number is not a saving percentage
A kilometre-per-litre figure measures distance against liquid volume. A kilometre-per-kilogram figure measures distance against mass. Comparing the headline numbers as though they use a common denominator would misread the specification. Tour S offers petrol and CNG versions, but its published consumption figures cannot be ranked as a fuel-bill percentage without knowing what the fuel costs.
An operator can build a useful worksheet by keeping a separate cost-per-distance calculation for each fuel. Divide the locally paid fuel price by the consumption figure being used, while keeping the unit consistent. If using brochure consumption, label the result as a brochure-based estimate. Replace it with recorded consumption when evaluating the vehicle's actual work.
Keep petrol used during a CNG vehicle's duty in the record as well. The official description identifies factory S-CNG and the availability of petrol operation. A worksheet that records only gas purchases could miss part of the fuel account. The relevant comparison is the whole operating period, not the most flattering entry from a filling receipt.
The taxi duty matters as much as the fuel
Maruti's specification page identifies a manual transmission and a five-person seating capacity. Count the driver within the vehicle's total occupancy when planning passenger assignments. Also check the actual cabin and access with the people and bags expected on the route, rather than assuming a sedan's body shape resolves every transfer requirement.
The petrol specification lists a 382-litre boot. That is a figure for the displayed petrol specification, not a verified luggage figure for the CNG version. It should not be copied into a CNG airport-transfer plan without checking the actual arrangement. Representative suitcases provide a more useful handover test than an unsupported assumption about identical boot space.
This distinction is particularly important for Tour S. A sedan taxi may be asked to carry passengers and their luggage simultaneously, so a fuel decision also becomes a packaging decision. An operator comparing shifts should preserve the same passenger and baggage requirement for both versions. Otherwise the comparison may accidentally substitute a different service.
Use the speed figure when making a timetable
The official Tour S FAQ publishes a top speed of 80 km/h and identifies a speed limiting function among its features. That is relevant to dispatch planning. It is not a promised average speed, and it does not tell an operator how quickly a journey will be completed after traffic, pickup stops and passenger loading are included.
For an intercity duty, write down the arrival commitment before deciding whether the car fits the work. Build allowance for breaks, queues and the return leg instead of converting a distance directly into an idealised running time. A lower fuel estimate cannot rescue a schedule that does not match the vehicle's intended operation.
Who this explanation is for
This is most useful to an owner-driver or fleet manager comparing Tour S fuel versions for a repeatable duty. Start with the route, occupancy and luggage requirement, then add measured fuel spending and time away from service. The brochure figures supply a consistent reference point; the operating record supplies the evidence for that particular business.
For a short demonstration, ask to see the fuel-related displays and have the version identified clearly on the paperwork. For a longer evaluation, keep the same route and a comparable load. Record unusual delays rather than allowing them to disappear into an average that appears more representative than the underlying trip.
