ACAP's May 2026 Tape Lifts the Light-Passenger Market 6.5% to 25,080 Units With 100%-Electric Share Hitting 27.9% — Year-to-Date Volume Hits 110,731 (+9.8%) as VW, Peugeot and Mercedes-Benz Lead the Brand Stack

The Associação Automóvel de Portugal (ACAP) released the May 2026 matrículas tape on Monday 1 June, and the headline read on Portugal's light-passenger market is a clear continuation of the post-Spring acceleration. The single-month print landed at 25,080 units, up 6.5% year-on-year, lifting the January-to-May cumulative to 110,731 units on a 9.8% YoY step — the strongest start-of-year stretch the Portuguese auto market has logged since the post-pandemic recovery cycle of 2023.

The Electric Mix Crosses Another Threshold

The structural story buried inside ACAP's monthly press release is the powertrain mix. The 100%-electric (BEV) share of light-passenger matrículas hit 27.9% in May, lifting the year-to-date BEV share to 24.5%. The combined alternative-energy slice — BEV plus plug-in hybrid plus conventional hybrid — reached 73.7% of January-to-May volume, meaning fewer than one in four new cars sold in Portugal in 2026 runs on a pure internal-combustion powertrain.

The 27.9% May BEV print is the first single month above the 27% mark in the Portuguese tape and slots Portugal squarely into the top tier of EU member-state BEV penetration alongside Sweden, the Netherlands and Denmark. ACAP attributed the continued lift to "growing consumer adoption of electric mobility" — diplomatic phrasing for what is now an unambiguous structural shift, helped along by the Fundo Ambiental's reopened €4,000–€5,000 EV incentive window (covered in our 24 April report) and the steady Mobi.E charging-network rollout under the EGME tariff (detailed in our EV charging guide).

Brand Ranking — A Tighter Top Three

The May brand stack tightened across the top three, with the leader-to-runner-up gap closing to under ten units:

• Volkswagen — 1,813 units (May leader)
• Peugeot — 1,804 units (within nine of VW)
• Mercedes-Benz — 1,764 units (within 49 of VW)

ECO's parallel coverage on Monday flagged Mercedes-Benz as the leader of the "segmento alto" premium tape, a positioning the brand has held since the 2024 model refresh. Tesla and the Chinese EV brands (BYD, MG, Leapmotor) — which have been a focus of our recent EV coverage including the Tesla worst-Portuguese-month-in-three-years piece from 11 May — did not break the May top three at the brand level, though their model-level contribution to the 27.9% BEV share remains material.

Commercial and Heavy Tapes

Beyond the light-passenger headline, the commercial and heavy reads tell two different stories:

• Light commercial vehicles: 3,235 units in May, +13% YoY; YTD 13,328, +2.3%. The May lift reflects strong demand from logistics and last-mile-delivery operators, including the post-Uber-Glovo competitive flow on the entrega economy.
• Heavy vehicles: 589 units in May, -7.2% YoY; YTD 3,567, +28.3%. The single-month dip sits inside a strong YTD acceleration — Portugal's heavy-vehicle market is logging its best year of the post-2019 cycle even allowing for the May softness.

Total new matriculations across all categories landed at 28,904 units in May (+6.9%) and 127,626 YTD (+9.4%).

The Macro Read

The May data confirms a Portuguese auto market that is structurally tighter than the EU-27 average on three dimensions. First, BEV penetration at 27.9% is roughly double the EU-27 single-month average reported by ACEA for April. Second, the alternative-energy share above 73% is exceeded in Western Europe only by the Nordic countries. Third, the 9.8% YTD growth rate runs well above the EU-27 +5.6% YTD tape for the same window. The combination — strong volume, strong electrification — has not historically co-existed in Portugal. The Fundo Ambiental subsidy, the Mobi.E network maturation and the IUC reform that moved annual road-tax payments off the matrícula anniversary (covered in our IUC overhaul brief) appear to be doing their work in sequence.

What This Means for Expats

• If you are buying new in 2026: The BEV/PHEV/HEV mix is now the default offering across the dealer network — internal-combustion-only inventory has been compressing for two years. Order lead times on the top BEV models are tightening as Portuguese demand catches up with delivery capacity.
• If you are importing a used car: Our importing-a-car guide walks through the ISV and IUC architecture. The new IUC schedule (April-July-October quarterly billing) applies regardless of fuel type. ISV remains heavily weighted on the CO2 grid, which now penalises non-electric imports harder than at any prior point.
• If you commute and are EV-curious: Combine the ACAP brand pricing with the EGME charging tariff and the Mobi.E roaming agreements (full breakdown in our EV charging guide) — the 30% EGME drop has materially shifted the total-cost-of-ownership maths versus gasoline at €1.65/litre.

The next ACAP read — June 2026 matrículas — lands in the first week of July and will close the first-half count. On the May trajectory, H1 2026 looks set to clear 145,000 light-passenger units, the strongest H1 since 2018 and well above the 134,000 H1 average of the 2022-2024 stretch.
