# Three-quarters of UK's top PHEV models incompatible with rapid chargers Most plug-in hybrids face hours-long charging delays due to technical limitations. - **Source:** [Business | The Guardian](https://www.theguardian.com/uk/business) - **Published:** 2026-09-26 - **Topic:** [Business](https://brifing.si/c/business) - **Original article:** - **On Brifing:** https://brifing.si/s/37666422-851e-40fd-9311-b71ae1f817ba ## PHEV charging limitations exposed Analysis by ChargeUK reveals 74% of top-selling UK plug-in hybrids cannot use 50kW+ rapid chargers. Only 6 of 20 popular models like Ford Kuga and BMW 3 Series support this standard. This forces drivers to rely on slower chargers requiring several hours for meaningful range recovery. The limitation persists despite PHEVs being marketed as long-distance capable alternatives to pure EVs. ## Industry warns of 'petrol reliance' ChargeUK CEO Shane Brennan criticizes PHEVs as "costly petrol cars with heavy batteries" when not regularly charged. Government data shows many owners rarely plug in, making real-world emissions higher than lab tests indicate. The industry body argues promoting PHEV sales undermines electrification goals, as drivers default to combustion engines during long trips due to impractical charging times. ## Government policy contradictions Despite known emission discrepancies, UK regulators allowed PHEVs to count toward manufacturers' EV targets. Recent consultation documents admit official methods overestimate electric driving. The policy comes as PHEV registrations grew 35% year-over-year to 227,000 units, making them 2024's fastest-growing segment. Carmakers now lobby to further weaken pure EV mandates. ## Charging infrastructure disparity While rapid/ultra-rapid chargers deliver 75% of UK network capacity, none of top PHEVs support 150kW ultra-rapid charging. This contrasts with pure EVs - all top models handle 50kW+, with 64% supporting ultra-rapid. The gap persists despite rapid chargers comprising 25% of public points, creating operational disadvantages for PHEVs on long journeys. ## Market incentives shift Automakers recently increased combustion/hybrid discounts while reducing EV incentives as they approach annual ZEV targets. Autotrader data shows petrol car discounts rose to 11.9% in September as brands like Mercedes scaled back EV promotions. This comes amid threats like Nissan potentially withholding £170m Sunderland investment over regulatory concerns. ## Emission calculation flaws Government acknowledges PHEVs achieve far lower electric mileage than lab tests suggest. Real-world CO2 emissions exceed official figures due to infrequent charging. Despite this, officials cite PHEVs' 40% emissions advantage over conventional cars to justify their policy role. The discrepancy highlights challenges in aligning regulations with actual usage patterns. ## Technical compromise consequences PHEVs' dual powertrains create weight and complexity that limit charging capabilities. Their smaller batteries prioritize combustion engine support over fast-charging hardware. This design focus makes them fundamentally different from pure EVs in operational parameters, despite sharing 'electric' branding. The trade-off becomes apparent during long-distance travel. ## Electrification roadmap at risk Industry experts warn PHEV reliance may delay necessary charging infrastructure investments and consumer behavior changes. As manufacturers prioritize meeting interim targets through hybrids, development of pure EV technology and supporting ecosystems could slow. The situation creates tension between short-term compliance and long-term decarbonization goals. ## Sources covering this story - https://www.theguardian.com/environment/2026/sep/26/uk-plug-in-hybrid-electric-vehicles-rapid-chargers-analysis — --- _Summary written by Brifing from the original reporting.
