From September 2018, all cars must have been homologated under the new WLTP (Worldwide Hamonized Light Vehicles Test Procedure) test cycle which is designed to better replicate real life driving conditions.

BMW Group has now published revised fuel economy and emissions data for its entire range of vehicles in accordance with the new test procedure (WLTP). This means the full range of BMW and MINI vehicles sold in the UK is now fully compliant with the new test regime well ahead of the deadline.

The new testing procedure of WLTP is based on an approximation of the test conditions to real-world circumstances, which means that the values determined will also have a greater relevance to reality. Among the changes this involves are redefined, significantly stricter test conditions and higher speeds together with a substantially longer test duration (30 instead of 20 minutes). 

To obtain a more precise determination of CO2 emissions, the new test procedure includes not only standard equipment – as was previously the case – but also all optional equipment of a vehicle. This produces two values for each type of vehicle: the lowest and highest possible standard consumption value according to aerodynamics, weight and rolling resistance.

Thanks to WLTP, you will be able to better assess a vehicle’s consumption and CO2 emissions in the future. In the case of a specific vehicle configuration, the individual standard value will be indicated directly.

Despite the more stringent test requirements, the BMW range has increased on average by just 8g/km while the MINI average increase is just 5g/km.* BMW’s market-leading electric and plug-in hybrid range performed particularly well with the top-selling BMW 530e Saloon increasing by just 3 grams to 49g/km.

Customers can have confidence that the full range of BMW Group vehicles is compliant with the new testing requirements and offers a more compelling value proposition than ever. Buyers can also be sure that the figures supplied for all our vehicles are future-proof providing certainty in terms of future cost.
