BMW Group has re-tested its entire model range under the new WLTP test cycle ahead of the September deadline, and has stressed that it can offer factory orders on all models.

BMW’s plug-in hybrid 530e now emits 49g/km CO2.

Manufacturers have until the end of August to test their ranges under the Worldwide harmonised Light Vehicle Test Procedure (WLTP), which is designed to better replicate real-world driving conditions than the New European Drive Cycle (NEDC) it replaces. CO2 and fuel consumption rises of 20% are expected.

However, WLTP fuel economy data isn’t set to be made public until next year, and the corresponding CO2 emissions data won’t be used for tax purposes until April 2020 – there is no indication yet as to how these will shape up. Manufacturers still have to produce NEDC figures, to show compliance with EU range-wide CO2 emissions targets set for 2020/21, but these are now computer-converted from the WLTP results. These are often higher than ‘true’ NEDC figures, despite in many cases not being as a result of any mechanical changes, and company car tax has not been reformed to account for the increased CO2 emissions.

It’s this ‘NEDC Correlated’ data which BMW Group has now released. This shows an 8g/km average increase across the BMW range, though with the notable effect of taking the entire 1 Series and 3 Series line-up over 100g/km. The most efficient versions are the 116d (at 111g/km) and 320d ED (at 114g/km), though both models are due to be replaced with all-new cars.

For Mini, the range-wide average CO2 increase was 5g/km, with the recently-updated Cooper D (auto) hatch the only sub-100g/km non-hybrid in the line-up, at 99g/km.

Plug-in hybrids haven’t recorded significant increases; the BMW 530e iPerformance now offers 49g/km CO2 emissions – up 3g/km compared to its predecessor. The Mini Countryman Cooper S E All4 has moved from 49g/km to 55g/km under the new figures.

BMW UK national leasing manager, Adam Harley said: “With every vehicle offered compliant ahead of the new WLTP requirement deadline, we have good availability with factory orders available on all models.”
