Product Review

Product reviewed

Tata Sierra (Diesel Automatic, 6-speed torque converter; “top-end” variant) — a mileage-focused real-world test including city/highway driving and a refueling-based mileage calculation.

Key features mentioned

  • Diesel engine + automatic: 6-speed automatic torque converter
  • Performance specs cited: 118 bhp and 250 Nm
  • Driving modes: City mode used (sports mode mentioned but not used)
  • MID/range info: Trip B reset; mileage/range shown on the dashboard

Real mileage test setup & method

  • Diesel tank is filled and auto-cut is confirmed.
  • Refills are done “up to the top” for consistency.
  • Speed-controlled highway driving: testers keep to highway speed limits (generally not above ~120 km/h).
  • Route mix: mostly highway + some local driving (stated as ~60% highway, 40% local).
  • After driving, they refuel again from the same source and calculate mileage using:
    • liters added ÷ kilometers covered

Mileage / numerical results reported

  • Early segment (first ~8 km): 15.2 km/l
  • MID readings improve later:
    • Around the 48 km mark: ~17.3 km/l
    • Later run (including some local driving): ~18.1 km/l
  • Tank-expense calculation:
    • Distance traveled: 153 km
    • Fuel added: 9.32 liters
    • Calculated mileage: ~16.4 km/l
  • RPM observation:
    • At 120 km/h: roughly ~2000 rpm in 6th gear (suggesting low-rev highway cruising)

Pros mentioned

  • Good highway drivability with relaxed RPM (about 120 km/h ~2000 rpm in 6th gear)
  • Improving MID mileage during the test (rising toward ~17–18 km/l on the display)
  • Comfort for long travel implied by stable behavior across mixed highway/local use

Cons / limitations mentioned

  • The final refuel-based average (~16.4 km/l) is lower than the best MID readings seen earlier, implying either:
    • varying conditions/consumption, or
    • MID being optimistic vs the tank-to-tank method
  • Speed caps: results reflect controlled conditions, since the test avoids speeds beyond ~120 km/h

Comparisons made

  • Petrol variant comparison: petrol Sierra mileage is mentioned, but this write-up focuses on the diesel test
  • Nexon petrol mention: cited as giving ~20 km/l as a comparison point
  • Engine power comparison: diesel output is contrasted with a TGDI (160 bhp) figure, mainly for power context (not direct mileage comparison)

User experience notes from the video

  • Refueling method continues consistently (same general approach and source)
  • Emphasis on:
    • sticking to speed limits,
    • handling real traffic,
    • checking live data (MID and RPM)
  • Shows the car holding highway speeds without high engine revs

Overall verdict / recommendation

Recommended if you prioritize diesel highway cruising and relaxed RPM, but based on the tank-to-tank calculation (~16.4 km/l), the real-world average is solid rather than class-leading—especially compared to the cited ~20 km/l comparison (Nexon). The MID may show higher momentary figures, but the final calculated figure is the key takeaway.

Unique points mentioned (consolidated)

  1. Diesel auto mileage test begins after filling the tank; auto-cut confirmed
  2. Diesel automatic is 6-speed torque converter
  3. Test conducted in City mode (sports mode exists but not used)
  4. Trip B reset; range/mileage shown; Trip B example 696 km displayed
  5. Speed controlled to highway limits; not above ~120 km/h
  6. Performance specs cited: 118 bhp, 250 Nm
  7. Power comparison mentioned: TGDI 160 bhp (contextual)
  8. Early MID mileage 15.2 after first ~8 km
  9. Later MID stabilizes around 17–18 km/l (examples: 17.3, then 18.1)
  10. RPM observation: at 120 km/h ≈ 2000 rpm in 6th gear
  11. Mixed driving composition: ~60% highway + some local over ~30–40 km local segment
  12. Final tank calculation: 153 km on 9.32 liters → 16.4 km/l
  13. Refills are done to “top” at (ideally) the same pump/source

Speaker-based views/aspects (from subtitles)

  • Speaker 1 (main tester/host): refueling method, MID observations, speed/RPM observations, final tank-based mileage calculation
  • Speaker 2 (intermittent confirmations): short confirmations like “auto cut done / yes sir,” supporting refuel/sequence verification
