Sustainable mobility is shaping the agenda of city councils and manufacturers in Spain, where hybrid and plug-in hybrid vehicles have become a leading option for fleet renewal and compliance with new urban regulations. While these cars offer environmental and efficiency advantages, they also generate debate and are not without their technical and regulatory challenges.
The adoption of hybrid vehicles in public services and the private sector is steadily increasing, driven by emissions reduction targets and the rise of Low Emission Zones. However, uncertainties remain regarding their future in large cities, and technological challenges persist.
Hybrids in municipal and police fleets
Santa Cruz de Tenerife and Santander exemplify the commitment to hybrid mobility in public administration. In Tenerife, the public-private partnership Emmasa has added 15 new hybrid and electric vehicles to its fleet, bringing the total to 24 vehicles that replace the old diesel vans. This change will reduce CO₂ emissions by approximately 20 tons per year , reinforcing the city's commitment to sustainability and energy conservation. Furthermore, the project represents an investment of around €600.000, including the installation of charging points and the application for European funding under the MOVES III Plan.
The Santander Local Police have added four state-of-the-art Renault Arkana hybrid vehicles to their fleet . These models can operate in electric mode up to 80% of the time in urban areas , helping to reduce emissions and improve the efficiency of public safety services. The municipal investment, exceeding €165.000, reinforces the modernization of police resources and includes equipment adapted to their specific functions.
Advantages and problems of plug-in hybrids
Plug-in hybrid electric vehicles (PHEVs) are becoming increasingly popular in the Spanish market . They allow drivers to travel considerable distances in electric mode and qualify for the DGT's 'Zero' emissions sticker, facilitating access to restricted urban areas and Low Emission Zones. The most affordable models offer over 100 kilometers of electric range and are priced around €40.000, with SUVs from brands like Leapmotor, BYD, MG, and European offerings from Volkswagen, Skoda, Opel, and Mazda.
From a technical standpoint, PHEVs combine a combustion engine with an electric motor and a rechargeable battery, allowing them to operate in all-electric or hybrid mode depending on power or load demand. Some extended-range models use the combustion engine solely as a generator.
However, a recent report from JD Power warns of reliability issues in plug-in hybrids . The study indicates that, during the first three months of ownership, these vehicles report more problems than pure electric vehicles and traditional hybrids, especially regarding the combustion engine and electrical system. It also notes some frustration among users due to the proliferation of touchscreens, at the expense of physical controls, which makes it difficult to operate some basic functions.
Even so, the market shows diversity in reliability : some models excel in this area, while others score lower. The electrification trend continues to grow, and improvements in design and after-sales service are also in demand.
Urban limitations and evolving regulations
The rollout of Low Emission Zones in Spanish cities is transforming the rules for hybrids. Most municipalities allow vehicles with ECO and Zero Emission labels to circulate, but Granada is considering restricting access to non-plug-in hybrids during periods of high pollution . Under these circumstances, only electric and plug-in hybrid vehicles would be allowed to enter certain urban areas, setting a regulatory precedent that could be extended to other cities.
These regulations aim to improve air quality and reduce traffic in urban centers, but they raise debates about fairness for owners of conventional hybrids who have previously enjoyed environmental advantages.
Mercedes-Benz leadership in the plug-in hybrid segment
Mercedes-Benz excels in PHEV technology , offering a range that spans from compact models to sedans and SUVs, with both gasoline and diesel engines. Since the launch of the A 250 e, equipped with a 15,6 kWh battery and an electric range of approximately 70 km, the brand has expanded its lineup with versions that combine high performance and efficiency.
Mercedes-Benz is a pioneer in integrating electric motors into automatic transmissions and offering plug-in hybrid variants in premium and performance segments under the Mercedes-AMG brand. Furthermore, it is the only automaker to market diesel hybrid versions, optimizing range and fuel consumption. This approach has made the brand a sales leader in the PHEV segment , with over 13.000 units sold last year and excellent results projected for 2025.
The hybrid vehicle market in Spain is experiencing a period of growth and transformation . Electrification, incentivized by regulations, subsidies, and the commitment of manufacturers and government agencies, is driving a more sustainable renewal of the vehicle fleet. However, technical reliability, charging infrastructure, and regulation remain key challenges to consolidating this process.
