Mild-Hybrid (B5, B6) – Petrol
- In India, the B5 AWD mild-hybrid version records around 8.07 L/100 km, which equals roughly 12.4 km/l Volvo CarsAutocar India.
- In international tests (Autocar India), the XC90’s official mileage is also about 12.39 km/l Autocar India.
Plug-in Hybrid (T8 Recharge) – Petrol + Electric
- Real-world drivers report that the XC90 T8 Recharge can hit around 57 mpg, which converts to approximately 24 km/l—but this depends heavily on using electric power first and the driving conditions Reddit.
- Independent data (VehicleScore) indicates that the T8 PHEV can achieve 235 MPG, or about 1.2 L/100 km, under ideal test-cycle conditions—far from real-life driving scenarios vehiclescore.co.uk.
- Parkers data notes that you might get into the low 30 mpg zone (around 13 km/l) on country roads if the battery is recharged often and you drive efficiently Parkers.
So, Where Did “55 km/l” Come From?
That claim seems to stem from viral YouTube content—not from official specs. The videos sensationally state an unrealistic “55.6 km/l”, but there’s no factual reporting or credible testing to back it up YouTube+1.
Summary Table
| Model / Powertrain | Realistic Fuel Efficiency |
|---|---|
| Mild-Hybrid (B5/B6) | ~12–13 km/l |
| Plug-in Hybrid (T8 PHEV) | ~24 km/l (with frequent charging), or 13 km/l on mixed roads |
| Viral Claim (YouTube) | 55 km/l — not supported by any reliable data |
Final Verdict
Bottom line: The Volvo XC90 does not—and realistically cannot—achieve 55 km per litre. Genuine figures show around 12 km/l for mild-hybrid versions, and up to about 24 km/l if you’re clever with charging and driving the plug-in hybrid model. The 55 km/l claim is pure clickbait with no solid backing.
