Understanding New Zealand’s WLTP: New Emissions and Energy Economy Testing Standards
We look at vehicles differently. As we say, it’s more than just a new car, it’s the start of a 10-year relationship, courtesy of our unbeatable Diamond Advantage Warranty.
As part of New Zealand’s commitment to a more sustainable future, vehicle emissions and energy economy testing has transitioned to a more accurate and globally recognised standard. The Worldwide Harmonised Light Vehicles Testing Procedure (WLTP) now provides consumers with better tools to compare vehicles and make informed purchasing decisions.
What Is the WLTP?
The WLTP is an internationally standardised laboratory test that measures the fuel economy, CO2 emissions, and electric vehicle (EV) range for passenger and light commercial vehicles. This updated testing method replaces the older NEDC (New European Driving Cycle), which was less reflective of real-world driving conditions.
Key features of the WLTP include:
- Dynamic and realistic test cycles: Incorporating urban, suburban, and motorway driving to better replicate daily driving patterns.
- Four speed phases: Low, medium, high, and extra-high speeds (excluding extra-high in New Zealand to match local conditions).
- Detailed vehicle specifications: Accounting for factors like larger tyres, sunroofs, and body kits that can affect fuel economy.
These updates provide a more accurate picture of a vehicle’s efficiency and emissions, helping buyers make environmentally and economically conscious decisions.
How Does This Affect You?
For consumers, WLTP testing offers more realistic data to compare vehicles’ emissions and energy consumption. The results are displayed on Vehicle Emissions and Energy Economy Labels, which are legally required on all light vehicles under 3.5 tonnes offered for sale in New Zealand.
Key information on the label includes:
- Energy economy rating (up to 6 stars for the most efficient vehicles)
- Carbon dioxide emissions rating (up to 6 stars for the lowest-emitting vehicles)
- Fuel economy or electricity usage (L/100 km or kWh/100 km)
- Estimated yearly running costs for driving 14,000 km, including road user charges for applicable vehicles
Why Does This Matter?
Choosing a vehicle with a high energy efficiency rating and low emissions helps reduce your environmental footprint and lowers running costs. For Christchurch drivers, this could mean finding a car that not only suits your lifestyle but also makes a difference for the planet.
