What is the mileage of Tata Nexon (Petrol variant) on Highways?

In highway driving, the Tata Nexon petrol typically delivers around 16–20 km/l, depending on the engine variant, transmission, driving style, traffic conditions, and cruising speed. If you're driving steadily at 80–100 km/h with minimal braking and acceleration, many owners report fuel efficiency closer to the upper end of this range. However, aggressive driving or heavily loaded trips can bring the mileage down.

I've driven and analyzed several turbo-petrol compact SUVs over the years, and one thing I've consistently noticed is that manufacturer-claimed mileage and real-world highway mileage are rarely identical. The Tata Nexon is no exception. Under controlled test conditions, the figures look impressive, but on actual Indian highways, fuel efficiency depends far more on how you drive than on the specification sheet.

Tata Nexon Petrol Mileage by Variant

The Tata Nexon is available with both 6-speed Manual (MT) and 7-speed DCA Automatic (latest generation), and each performs slightly differently on highways.

One observation that's often overlooked is that modern dual-clutch automatics (DCA) have become much more fuel-efficient than older automatic gearboxes. On long highway drives, the mileage difference between the manual and DCA versions is usually smaller than many buyers expect.

What Affects Highway Mileage?

Fuel efficiency isn't determined by the engine alone.

Several real-world factors have a significant impact.

1. Cruising Speed

The Nexon petrol generally delivers its best highway mileage when cruising between 80 and 100 km/h.

Driving consistently above 110–120 km/h increases aerodynamic drag and fuel consumption noticeably.

2. Driving Style

Smooth driving makes a remarkable difference.

Frequent:

• Hard acceleration.

• Sudden braking.

• Rapid overtaking.

can reduce mileage by several kilometers per litre.

One pattern I've seen across almost every turbo-petrol SUV is that gentle throttle inputs often improve highway efficiency more than many people realize.

3. Traffic Conditions

Even on highways, conditions vary.

Mileage usually decreases in:

• Stop-and-go traffic.

• Toll plazas.

• Congested expressways.

• Mountain roads.

Open highways with consistent speeds generally provide the best results.

4. Vehicle Load

A fully loaded vehicle carrying five passengers and luggage naturally consumes more fuel than a lightly loaded one.

Roof carriers and roof boxes can also reduce efficiency by increasing aerodynamic resistance.

5. Tyre Pressure

This is probably one of the simplest yet most overlooked factors.

Underinflated tyres increase rolling resistance, forcing the engine to work harder and consume more fuel.

Maintaining the manufacturer's recommended tyre pressure can noticeably improve fuel efficiency over long journeys.

Tips to Improve Tata Nexon Petrol Mileage

If your goal is maximum highway mileage, a few practical habits can make a meaningful difference.

I generally recommend:

• Maintain a steady cruising speed between 80–100 km/h.

• Accelerate gradually instead of flooring the accelerator.

• Anticipate traffic ahead to avoid unnecessary braking.

• Keep tyre pressure properly maintained.

• Service the vehicle according to Tata's maintenance schedule.

• Remove unnecessary weight from the boot.

• Use good-quality fuel from reliable fuel stations.

• Avoid excessive idling during long stops.

One habit I've personally found effective is using cruise control whenever road conditions safely allow it. Maintaining a constant speed often results in more consistent fuel efficiency than frequent manual throttle adjustments.

City vs Highway Mileage

Many buyers notice a significant difference between city and highway fuel economy.

That's completely normal.

In city traffic, frequent stopping, lower gears, and idling increase fuel consumption.

On highways, the engine operates more efficiently because it maintains stable speeds for longer periods.

Petrol vs Diesel Nexon: Which Is More Fuel Efficient?

Many buyers compare the petrol and diesel versions before making a purchase.

Here's a quick comparison.

If you mostly drive within the city and cover moderate yearly distances, the petrol variant often makes more financial sense.

However, drivers covering 20,000 km or more annually, especially on highways, may find the diesel variant more economical in the long run.

Tata Nexon Petrol Mileage at a Glance

The Tata Nexon petrol is capable of delivering 16–20 km/l on highways under real-world conditions, making it one of the more efficient turbo-petrol compact SUVs in its segment. While official ARAI figures provide a useful benchmark, actual fuel economy depends far more on driving habits, vehicle condition, and road conditions. If you maintain steady cruising speeds, keep the vehicle well serviced, and avoid aggressive acceleration, the Nexon petrol can offer an excellent balance of performance, comfort, and fuel efficiency for both daily commuting and long highway journeys.

Frequently Asked Questions (FAQs)

1. What is the real highway mileage of the Tata Nexon petrol?

Most owners can expect around 16–20 km/l on highways under normal driving conditions.

2. Does the Tata Nexon automatic give lower mileage than the manual?

Generally, yes, but the difference is relatively small with the newer DCA automatic, especially during steady highway driving.

3. At what speed does the Tata Nexon petrol deliver the best mileage?

Fuel efficiency is usually highest when cruising consistently between 80 and 100 km/h.

4. Does using the air conditioner reduce highway mileage?

Yes. Running the air conditioner increases engine load slightly, which can reduce fuel efficiency, particularly during slow-moving traffic or steep climbs.

5. Is the Tata Nexon petrol suitable for long highway trips?

Absolutely. The turbo-petrol engine offers comfortable highway performance, stable cruising, and respectable real-world fuel efficiency, making it a practical choice for occasional and regular long-distance travel.

Must Read: How is the build quality of Tata Nexon?

Tata Nexon is a good hatchback but when it comes to mileage, it may disappoint you a little bit. Tata Company claims the average of 17 kmpl on highways in petrol variant for both manual and automatic transmission. Even I have seen a couple of videos where YouTube bloggers claim the same.

But the real picture is very different, I have two friends who own Tata Nexon and like me, they are also not satisfied with the mileage part. Before first service of their vehicles, the mileage on city roads was around 8-9 kmpl and on highways was 9-10 kmpl. They thought that maybe after the first service it will get better, but nothing like that happened. When after the service they drove the vehicle, they got the following mileage on the given modes:

1. City: 8-9 kmpl

2. Eco: 9-10 kmpl

3. Sport: 7-8 kmpl

On highways when they drove with Ac on, they got only 11-12 kmpl mileage. See, Nexon is a heavy vehicle that weighs more than 1300 kg and such heavy vehicles require an engine with high torque which leads to high fuel consumption beyond any doubt.
