If you’ve been sitting on the fence deciding whether to buy a Tata Nexon with the 1.5L turbo diesel-manual, congratulations: you are about to learn how much your wallet will weep in traffic and how smug you’ll feel on the open road. This review breaks down a tank-full-to-tank-full real-world mileage test, what the numbers mean for everyday ownership, and whether the Nexon’s diesel-MT is the sensible, frugal, or slightly optimistic choice you were promised by the brochure.
Introduction
The Tata Nexon 1.5L turbo diesel-MT is a compact SUV aimed at buyers who want diesel efficiency without getting into full-sized SUV territory. It pairs a 1.5-litre turbocharged diesel engine with a manual gearbox, a setup marketed toward drivers who prefer engagement and economy. In practice, this car is for people who commute daily through stop-start urban jungles but occasionally take long highway runs—preferably when the AC isn’t monopolizing the engine’s will to live.
Testing Method — Because Numbers Are Only Useful When Earnest
This review uses the tried-and-true tank-full-to-tank-full method. The testers filled the tank, reset the trip meter, and completed a 100 km city loop through Delhi NCR at an average speed of about 40 km/h. After refilling, they recorded diesel consumed and repeated the exercise on a highway stretch (Sohna, on the Delhi–Mumbai expressway) at a cruising speed of roughly 100 km/h for another 100+ km. Fuel price used for the calculations was Rs. 88 per litre (Gurgaon, June 2024).
Key Features
1. 1.5L Turbo Diesel with Manual Gearbox
Yes, it’s a 1.5-litre turbocharged diesel paired with a manual gearbox—the relatively rare combo that promises torque when you need it and control when you don’t want the car shifting for you during traffic tantrums. The engine is designed to be torque-rich for city overtakes and relaxed cruising on highways.
2. Tank Capacity: 44 Litres
The Nexon’s 44-litre tank is sensible math: big enough to deliver useful range, small enough to avoid turning gas stations into lifestyle destinations. The testers used a 90% usable fuel assumption to calculate real-world ranges, producing figures that make long drives feasible without continuous fuel angst.
3. Economy-Focused Calibration
The powertrain is clearly tuned with fuel efficiency in mind—especially at constant speeds. The onboard behavior favors steady consumption on highways while accepting some punishment in city stop-start conditions.
4. Practical On-Road Behavior (City and Highway)
On the road, the Nexon behaves like a compact SUV that knows its job: comfy ride, decent composure at higher speeds, and enough grunt for overtakes when you’re not in a hurry to win a drag race at a traffic signal.
Real-World Mileage Results
Let’s get to the part where the numbers speak, and occasionally grunt under the weight of reality. In a 100 km city run (average speed ~40 km/h), the Nexon returned 15.82 kmpl. On the highway loop, cruised at 100 km/h, it returned 21.61 kmpl. The official claimed figure is 23.23 kmpl, so the real-world deviations were a painful -32% in the city and a more forgiving -7% on the highway.
Pros and Cons
Pros
– Highway efficiency is genuinely good: 21.61 kmpl at 100 km/h is the sort of number that turns long drives into mildly enjoyable financial decisions. The full-tank highway range can be as high as 856 km under ideal conditions.
– Practical tank size: 44 litres gives you real range even if you forget where the next fuel station is.
– Engaging manual gearbox: for drivers who enjoy being involved, the manual box provides a satisfying mechanical connection.
– Consistent testing method: the tank-full-to-tank-full approach and repeatable routes give credible, relatable numbers—not brochure fantasy.
Cons
– City mileage is disappointing: 15.82 kmpl in urban traffic is far below the claimed figure and will sting if your life is 90% commuting and 10% dreaming of open highways.
– Claimed vs actual discrepancy: a -32% city deviation is not a rounding error; it’s a reality check.
– Per-kilometre running cost in city: Rs. 5.56/km at Rs. 88/l is a number you’ll feel more than nod at.
– Diesel enthusiasm declining: diesel options in this segment are slowly evaporating in some markets, so future resale and servicing realities matter.
User Experience — How It Feels to Live With
Driving the Nexon in the city feels like dating someone who’s wonderful on paper but occasionally forgets they’re in a crowded train carriage. The turbo-diesel offers ample low-end poke for quick lane changes and overtakes, but the stop-start environment eats efficiency, and you’ll notice the fuel gauge dip faster than your patience in peak-hour Gurgaon. The manual gearbox is predictable and satisfying; shifts are precise without being fussy.
On the highway, the Nexon relaxes into its skin. At 100 km/h the engine sings at a reasonable tempo and returns that 21.61 kmpl figure that makes you think, “Maybe I should drive to Goa this weekend.” The cabin is composed enough for long stints, and the fuel tank means fuel stops are less frequent and more deliberate.
Comparison with Alternatives
If we compare it broadly to rival compact SUVs (some of which also come in diesel flavours), the Nexon’s highway efficiency is competitive; its city mileage less so. Alternatives, especially petrol turbo models and hybrids, can be more efficient in mixed driving or offer better claimed figures in showroom tests. Some rivals are also offering more refined diesels or automatic options, which might matter if you’re a traffic-weary commuter who hates clutch work.
In short: if your driving includes regular long highway runs, the Nexon can be smarter money than a petrol-only rival. If your life is mostly urban crawling, a petrol or hybrid competitor might be kinder to your pocket and stress levels.
Who Should Buy This
Buy the Nexon 1.5L diesel-MT if: you regularly drive long highway stretches, cherish manual gear engagement, and want a compact SUV that can deliver high highway mileage and long single-tank range. Also suitable if diesel infrastructure and resale value in your area are still decent.
Skip it if: you live in a city where commute is 70–90% of your driving, you hate clutch work, or diesel maintenance and resale are questionable in your market. In such cases, a petrol turbo or hybrid alternative will likely be less painful on your monthly ledger.
Value for Money
Value is a delicate arithmetic of sticker price, running cost, and how much you enjoy driving. The Nexon scores on running costs for highway-biased users—21.61 kmpl translates to Rs. 4.07/km at Rs. 88/l, which is respectable. However, in city-centric usage the cost jumps to Rs. 5.56/km.
The claim-versus-reality gap—particularly the -32% city deviation—erodes perceived value for heavy urban users. If you plan to do a 70% city/30% highway split, expect an effective mileage around 17.56 kmpl and a per-kilometre fuel cost close to Rs. 5.01. On a full tank filled to 90%, you’ll be paying about Rs. 3,485 each time you stop to fill up—numbers that add up fast.
Practical scenarios:
– Long-distance weekly traveler: You’ll love the highway numbers and infrequent fuel stops—excellent value.
– Daily city commuter: You’ll find yourself refuelling more often than you’d like and occasionally cursing the claimed mileage on the brochure.
– Mixed driving (50/50): Expect roughly 18.72 kmpl effective mileage—manageable, not miraculous.
There’s also the intangible: ownership pleasure. If you enjoy driving, the manual diesel offers a rewarding experience that some automatic or petrol rivals can’t match. That satisfaction has a subtle value that doesn’t show on fuel receipts—but it’s real.
My honest recommendation: If at least half of your kilometers are highway runs, the Nexon 1.5L diesel-MT is a solid, economical, and engaging choice. If your life is one long stoplight, consider a petrol or hybrid rival that’ll save you money and temper your daily disappointment. Buy it for the highways, not for the city.
