New Car Registrations YoY

New Car Registrations YoY is the monthly growth rate for new passenger cars registered in the EU. ACEA, the European Automobile Manufacturers Association, builds it from national licensing files as a full count with no sampling. It covers all 27 EU states and counts every new entry, including fleet and company cars. It excludes used cars plus the UK, Norway, Switzerland and Iceland, which appear in a separate table.

A positive reading means more registrations than the same span a year earlier, while a negative reading means fewer. There is no target band and zero is the only break line between growth and contraction.

Each release covers one calendar month and appears once per reference month in the second half of the next month. It is published under embargo at 06:00 Brussels time on a pre-announced date. In some years one summer release is skipped and its figures first appear inside the next release. Each release gives commentary plus market and fuel mix tables, monthly and year to date, and maker tables with shares.

Year data are provisional and open to revision, and each release updates the prior year span. Annual files are consolidated each year from corrected national files.

Moves come from shifts across six fuel types plus gaps across national markets, since the EU total is a straight sum. Fuel shares sum to 100% of the EU total in every release.

• Battery-electric (BEV, pure-electric cars): cars running only on batteries charged from the grid.
• Plug-in hybrid (PHEV, rechargeable hybrids): cars with an engine plus a battery charged by plug.
• Hybrid-electric (HEV, non-plug hybrids including full and mild hybrids): cars pairing an engine with a small self-charging battery.
• Petrol: cars burning petrol in an internal combustion engine with a falling share over time.
• Diesel: cars burning diesel in an internal combustion engine with a falling share over time.
• Others: fuel-cell electric vehicles, natural gas, LPG, ethanol and similar residual fuels.

In one past release registrations fell 18.3% to 643637 units from 787812 a year earlier. Germany fell 27.8% and France fell 24.3%, with Italy down 13.4% and Spain down 6.5%. Battery-electric cars fell 43.9% to 92627 units for a 14.4% share, down from 21%. The drop was led by Germany down 68.8% and France down 33.1% after purchase support ended.

Plug-in hybrids fell 22.3% while petrol fell 17.1% and diesel fell 26.4%. Hybrid-electrics were the sole gainer, up 6.6% to 201552 units for a 31.3% share, up from 24%. Year to date registrations still rose 1.4% to almost 7.2 million units, so one thin summer month hid the trend.

1. EU total: sum registrations across all 27 states for the month, year to date span or full year from provisional national files.
2. Year on year change: subtract same span a year earlier units from this span units, divide by a year earlier units and multiply by 100. For example, 700000 units versus 677491 a year earlier gives about 3.3%.
3. Market share: divide a part, such as battery-electric units, by the EU total for the same span and multiply by 100. For example, 150000 battery-electric cars out of 700000 total gives about 21.4%.
4. Maker shares: ACEA estimates each maker share from market totals, not from directly reported maker files. There is no weighting and no seasonal or working-day adjustment in any step.
