WLTP vs NEDC - What's the Difference?
WLTP replaced the old NEDC test in 2017 because NEDC was completely unrealistic. Real-world driving showed cars using 20-40% more fuel than NEDC suggested. WLTP isn't perfect, but it's much closer to reality.
WLTP Advantages
- Real-World Conditions: Tests include hills, acceleration, braking
- Variable Speeds: From 0-131 km/h vs NEDC's max 120 km/h
- Longer Tests: 30 minutes vs NEDC's 20 minutes
- Individual Testing: Each variant tested separately
- Optional Equipment: Air con, larger wheels affect results
Impact on VRT
- WLTP figures are typically 10-25% higher than NEDC
- This means higher VRT for the same car
- But WLTP better reflects actual fuel costs
- Revenue uses whichever test was current when car was certified
WLTP Reality Check
WLTP is closer to real-world emissions, but still optimistic. Expect your actual fuel consumption to be 10-20% higher than WLTP suggests.
Understanding WLTP Test Phases
Four WLTP Phases
| Phase | Speed Range | Duration | Represents |
|---|---|---|---|
| Low | 0-56 km/h | 589 seconds | Urban driving |
| Medium | 0-76 km/h | 433 seconds | Suburban driving |
| High | 0-97 km/h | 455 seconds | Rural roads |
| Extra-High | 0-131 km/h | 323 seconds | Motorway driving |
Factors Affecting WLTP Results
- Vehicle Weight: Heavier cars use more fuel
- Aerodynamics: Drag coefficient affects high-speed efficiency
- Tire Size: Larger wheels increase rolling resistance
- Optional Equipment: Air conditioning, sunroof add weight
- Transmission: Manual vs automatic vs CVT differences
WLTP Variants
The same car model can have multiple WLTP ratings depending on engine, transmission, and equipment. Always use the specific figure for your exact variant.
