If you think fuel economy is a romantic comedy between claimed numbers and reality, welcome to the Hyundai Exter 1.2L petrol-automatic’s love triangle. This neat little compact-SUV-ish thing promises frugal miles on paper and occasionally delivers—mostly on the highway, grudgingly in the city. We put it through a textbook tank-full-to-tank-full torture test on March 13, 2024, across Delhi NCR traffic and the Delhi–Mumbai expressway to see whether Hyundai’s official numbers were dreams or nightmares.
What the Exter Is (And Who It’s For)
The Exter tested here is the 1.2L petrol with an automatic gearbox. Think of it as a practical, city-focused runabout that occasionally moonlights as a long-distance courier when the mood strikes. It’s aimed at urban drivers who want compact dimensions, modern looks and decent efficiency without turning into a fuel-sipping saint. If your calendar has more parking-lot runs, school drop-offs and shopping hauls than weekend highway escapes, the Exter is trying to be your indifferent but dependable companion.
Key Features: What Matters for Mileage Junkies
Tank-full-to-tank-full Testing Method
No mystical calculators here—just the old reliable: fill to the brim, reset trip metre, drive, refill and note how much went back into the tank. The testers ran 100km in city conditions at an average speed of 22 km/h (that’s Delhi NCR traffic in a nutshell) and about 104km on the Delhi–Mumbai expressway at a cruising target of 100 km/h, ending with an average speed of 73 km/h for the highway segment. Real-world, reproducible, and deliciously unglamorous.
City and Highway Mileage Numbers
The city run returned 15.19 kmpl. The highway returned 18.37 kmpl. If you prefer your numbers in blunt-force terms: city driving was about 21% worse than Hyundai’s claimed 19.2 kmpl, while the highway figure was only 4% shy. In human language: the Exter gets more polite with speed and steady RPMs, but becomes a little petulant in bumper-to-bumper life.
Fuel Price & Per-Kilometre Cost
On the day of testing in Gurgaon, petrol was Rs. 97 per litre. That made the per-kilometre fuel cost roughly Rs. 6.39 in city conditions and Rs. 5.28 on the highway. If you like spreadsheets for your existential dread, the test also provided custom mixes—for a 50/50 city-highway split, expect around 16.78 kmpl and about Rs. 5.78 per km.
Tank Capacity and Range
The Exter’s fuel tank is 37 litres — not especially generous, not stingy. Using realistic mileage estimates and assuming 90% usable fuel, you can expect a range anywhere from roughly 506 km (all-city use) to about 612 km (all-highway). An even split gets you about 559 km between visits to the dispenser of sorrow.
Pros and Cons
Pros
– Reasonably honest highway efficiency: 18.37 kmpl is not headline-making but it’s respectable for a petrol automatic in this segment, and only 4% under the claimed figure.
– Predictable real-world performance: the tested city/hwy combos give you a realistic idea of costs and range, which is useful for budgeting.
– Compact, practical: 37-litre tank and expected range mean fewer surprise fuel stops on longer drives.
Cons
– City thirst: 15.19 kmpl in town is significantly lower than the claimed figure—about a 21% deficit. That adds up if your life is largely traffic lights and mains gridlock.
– Per-kilometre cost isn’t subtle: at Rs. 97/litre, city driving at Rs. 6.39/km starts to feel expensive compared to smaller hatchbacks or mild-hybrid rivals.
– Emotional whiplash: marketing claims versus reality can leave you grumpier than the car’s fuel needle.
User Experience: Using the Exter Day-to-Day
Driving the Exter in the city felt like dealing with someone who insists on making sense only when they are relaxed. In stop-start Delhi traffic, the average speed over the 100 km run was 22 km/h and the driving time stretched to about 4.5 hours. The car’s appetite increases predictably under those conditions. On the expressway, however, the whole posture changes: a steady 100 km/h cruise nets you a more polite 18+ kmpl and a quieter conscience. So if you live in a jam-heavy area, expect regular trips to the pump and a slightly sulky fuel economy readout.
Practical examples: if you’re doing daily commutes of 30–40 km through dense urban fabric, you’ll likely see numbers closer to that 15.19 kmpl mark — meaning weekly fuel bills that sting a little. If your pattern is office-to-home with regular highway runs, or weekend escapes to calmer roads, the Exter becomes less expensive to operate and somewhat likable again.
Comparison: Against Claimed Figures and Common Expectations
We’re not comparing apples to apples with competitors, because the numbers supplied here only come from this particular 1.2L petrol-automatic test. But the meaningful comparison is between Hyundai’s claimed 19.2 kmpl and the reality: the highway number (18.37 kmpl) comes close, showing only a 4% deviation, while the city number lags by 21%. In other words, Hyundai’s claim isn’t a complete fairy tale — but it’s a bedtime story told in highway lighting.
Compared to what most buyers expect from a compact petrol-automatic—urban practicality with occasional highway frugality—the Exter behaves predictably. It rewards steady-speed runs and punishes stop-start congestion. If you’re used to small, hyper-efficient hatchbacks, expect to pay a small premium in city running with the Exter.
Who Should Buy This
Buy the Exter if you: live somewhere with regular steady-speed driving (think highways or long arterial commutes), want a compact vehicle with sensible real-world range, and value Hyundai’s packaging and features over marginally better urban fuel numbers.
Don’t buy it if you: live strictly inside an urban grid of low-speed traffic and you’re obsessed with squeezing every last rupee of fuel efficiency out of your commute. For full-time city refugees and mileage absolutists, the 15 kmpl-ish urban reality may feel like financial therapy you didn’t ask for.
Value for Money
The Exter offers a pragmatic mix of features and real-world efficiency, but value depends heavily on your usage pattern. At Rs. 97 per litre, city-driven owners will pay around Rs. 6.39 per kilometre—read: this is not a budget commuter in the strictest sense. For mixed or highway-heavy drivers, the effective cost per kilometre drops into more palatable territory (around Rs. 5.28–5.78 depending on the split), making the Exter a sensible purchase for those who prioritize a compact SUV feel with reasonable operating costs.
So the Exter’s value is conditional: pay attention to your personal driving split. The vehicle rewards steady highways and penalizes urban idling. If the distribution of your driving time skews toward the highway, the purchase looks clever; if not, you might be buying a slightly thirstier companion than you expected.
After testing, I’d recommend the Hyundai Exter 1.2L petrol-automatic to buyers who split their life between city errands and highway stints, or who want a compact SUV that behaves sensibly at cruising speeds. If you live in dense urban sprawl and are allergic to fuel costs, look for a more urban-optimized powertrain or a small hybrid/CNG alternative. Otherwise, the Exter is a pragmatic, sometimes charming choice that simply asks you to be honest about your driving habits.
