The 2016 Ars Technica reportage offered a fascinating glimpse of a crucial moment for the automotive industry: the introduction of the BMW X5 xDrive40e, a plug-in hybrid SUV (PHEV) that promised to reconcile the luxury, performance and practicality typical of BMW with increased efficiency. Eight years later, it’s time to reflect on how this vehicle acted as a catalyst for the evolution of the electrified premium SUV segment, how technology progressed, and how consumers’ expectations and charging infrastructure changed radically. If in 2016 the hybrid X5 was perceived as a bold bet, an attempt to “apply the technology found in i3 and i8 to the regular production models”, today electrification is an ineludible component of the strategy of every car manufacturer of prestige. Our journey will explore the footprint left by the X5 xDrive40e, analyzing its pioneering role, the innovations it has introduced and the ones it has announced, and how the automotive landscape has been able to welcome and exceed the challenges posed by vehicles like this. From driving dynamics to progress in electric autonomy, from the evolution of charging infrastructures to changes in consumer regulations and preferences, we will examine how the idea of a “fun SUV to drive and efficient in consumption” has turned into a complex and layered reality, projecting us towards a future where the boundary between conventional and electric vehicle is increasingly blurred.
The Alba of Hybridation: The BMW X5 xDrive40e as a New Era Rainier
In 2016, the BMW X5 xDrive40e was not just another model in the Bavarian manufacturer's range; it represented a turning point significant, a true manifesto of BMW’s ambitions in the field of electrification. After exploring the boundaries of design and engineering with futuristic i3 and exclusive i8, BMW decided to bring the hybrid plug-in technology into a more traditional format and, above all, more sold: the luxury SUV. This choice was not random. The X5 was already the second best-selling model of BMW in the United States, a vehicle that embodied success, status and a certain functional robustness. The introduction of a plug-in hybrid version, as highlighted by the original article, aimed at “maintaining the BMW driving experience but with an additional dose of efficiency”. And in fact, under the hood, the coupling of a 2.0-litre four-cylinder turbo gasoline engine with a synchronous electric motor generated a combined power of 308 hp and 450 Nm of torque, respectable figures for a SUV of over 2.3 tons. The innovation was in the vehicle’s ability to travel up to 19 miles (about 30 km) in purely electric mode, a novelty for an SUV of these dimensions at the time. The 9 kWh battery, strategically located under the trunk, was an intelligent solution to integrate the electrical components without overly compromising the internal space, an intrinsic advantage of the SUV body. The power management system, with its three modes of driving (Comfort, Sport, Eco Pro) and the dedicated eDrive button for energy management, showed BMW’s commitment to offering the driver a sophisticated control over the interaction between the two engines. This technological complexity, while being managed by intelligent software, underlined the pioneering nature of the vehicle, which sought to offer the best of both worlds: the versatility and the power of the heat, combined with the efficiency and quietness of the electric for short trips. The driving experience, although the weight was not completely masked, benefited from the instant torque of the electric motor, making smooth departures and surprisingly vigorous acceleration for such a vehicle. Despite some criticisms about steering insulation and seat sealing, typical of many modern vehicles that abandon traditional hydraulic systems, the X5 xDrive40e managed to enchant for its ability to make driving pleasant, especially opting for electric mode. The charm resided not only in performance or potential efficiency, but in its ability to make the driver feel “almost pleased” in recovering energy and using it for short commissions, a new and rewarding feeling for SUV owners accustomed to high consumption. The starting price, aligned with diesel or petrol versions thanks to tax incentives, made it an economically attractive proposal, placing the X5 xDrive40e as a vehicle that not only anticipated the future but made it accessible in the present, although with the intrinsic challenges related to the charging infrastructure of time.
From Hybrid Plug-in to Total Electrification: The Evolution of the BMW Strategy
The introduction of the BMW X5 xDrive40e in 2016 marked a fundamental stage in strategic transition of BMW towards electrification, but it is only the first chapter of a much larger narrative. If the X5 PHEV was a successful experiment to bring technology “i” into mainstream models, the following years saw BMW dramatically speed up its electric roadmap, culminating in a growing range of purely electrical vehicles (BEV) under the brand “i” and in a continuous expansion of the plug-in hybrid offers. Initially, BMW adopted a “Power of Choice” approach, offering customers the possibility to choose from gasoline, diesel, plug-in and electric hybrids as well as many of its most popular models. This approach aimed at satisfying a wide range of needs and facilitating a gradual transition to consumers. The experience gained with the X5 xDrive40e was crucial: feedback on battery management, integration of the hybrid drive system and market acceptance informed the development of successive generations of PHEV, such as the plug-in hybrid versions of Series 3, Series 5, Series 7 and, of course, the subsequent iterations of the X5 itself. These new models have benefited from batteries with greater capacity, offering significantly higher electrical autonomy (often over 50-80 km in the WLTP cycle), and more powerful and efficient hybrid powertrains. In parallel, BMW invested heavily in the development of platforms dedicated to electric vehicles and battery technology. The transition from a “adapted” electric motor to a designed for optimal integration has improved overall efficiency and performance. BMW’s “Cluster Architecture” (CLAR) architecture has been designed from the beginning to support all forms of propulsion, allowing unprecedented production flexibility. However, the real breakthrough came with the introduction of BEV models such as BMW iX, i4, iX3 and i7, which represent the apex of BMW’s electrification strategy. These vehicles are not simple electrical versions of existing models; they were conceived from zero as electric vehicles, with a distinctive design, dedicated platforms that optimize space for batteries and aerodynamic efficiency, and a deep digital integration. The iX, in particular, has demonstrated BMW’s ambition to create a completely new experience, focusing on material sustainability, intuitive user interface and an electric autonomy that makes long journeys feasible. This passage from the hybrid plug-in, which although efficient in some circumstances remains a compromise between two worlds, to the pure electric vehicle, demonstrates an evolution not only technological but also philosophical within the company. The experience of the X5 xDrive40e, with its challenge to balance BMW’s traditional expectations with electrified innovation, provided priceless lessons that shaped the current direction. Today, BMW is not limited to “applying” technology; it is re-imagining and reinventing it to define its role in the future of mobility, with a clear commitment to decarbonization and technological leadership in the premium segment.
The Market of Hybrid SUVs: Growth, Consolidation and New Perspectives
Since 2016, the year when the BMW X5 xDrive40e made its entrance to the scene, the global hybrid SUV market has undergone a radical transformation, evolving from a niche of early innovators to a consolidated and driving segment for the entire automotive industry. BMW’s decision to hybridize the X5, one of its bestsellers, proved extremely far-sighted. The SUVs, already then, were rapidly rising in terms of popularity, appreciated for their versatility, elevated driving position, space and security perception. The addition of a hybrid motorization has solved one of the main objections to these vehicles: high consumption and emissions. The X5 xDrive40e showed that it was possible to have a premium SUV that was powerful, luxurious and, at the same time, more environmentally friendly and potentially cheaper to manage, at least for those who had the ability to recharge regularly. In the following years, almost every premium and generalist manufacturer has followed the example, introducing its full-sized plug-in and full-hybrid versions of SUVs. Models like the Volvo XC90 Recharge, the Mercedes-Benz GLE 350de, the Audi Q7 TFSI and, and multiple offers of Land Rover, Porsche and Lexus, have flooded the market, offering consumers an unprecedented choice. This proliferation was fueled by a combination of factors: increasingly stringent emissions regulations that encouraged manufacturers to reduce the CO2 average of their fleet, government incentives to purchase electrified vehicles (which made PHEVs often competitive in terms of final price compared to internal combustion counterparts), and increasing environmental awareness among consumers. The perception of the PHEV has passed from “niche technology” to “practical solution” for many, especially for those who were not yet ready for a fully electric car due to autonomy anxiety, perceived charging times or lack of adequate infrastructure in their areas. The plug-in hybrid SUVs, in particular, have become an ideal “bridge” towards electric mobility, allowing the owners to experience the electric guide for daily commissions and have the tranquility of a combustion engine for longer trips. The market has seen a clear differentiation even within the hybrid segment, with full-hybrid (HEV) that offer efficiency without the need for external charging, and plug-ins (PHEV) that maximize environmental and economic benefits through charging. The consolidation of the segment is also evident in the dimensions of vehicles, ranging from compact SUVs to large luxury SUVs to seven places, all available in hybrid configurations. The current challenge for the hybrid SUV market, however, lies in balancing efficiency expectations with real use. As the original article underlined for the X5 xDrive40e, the real fuel efficiency depends strongly on the frequency and regularity of battery charging. Without constant charging, a PHEV can end up consuming more petrol than a non-hybrid counterpart due to the additional weight of the battery and the electric motor. Despite this challenge, the versatility and immediate benefits offered by plug-in hybrid SUVs will continue to make them a popular choice, especially in a context of energy transition that will see convive different forms of drive for a significant time. Their evolution will continue, with the integration of increasingly advanced technologies, more efficient batteries and even more sophisticated energy management systems, ensuring that hybrid SUVs remain a key actor in the automotive future.
Refill infrastructure: Deficiation for Pochi to Essential Service
When the BMW X5 xDrive40e was launched in 2016, the theme of charging infrastructure was far from being a public priority or a widely available service. The original article clearly highlighted it, mentioning the difficulties encountered in finding public chargers and, worse still, the problem of “ICEing” (Internal Combustion Engine blocking Electric Vehicle charging spot), where gasoline or diesel vehicles occupied spaces dedicated to electric vehicles. This situation was a clear barrier to adoption for many potential buyers of PHEV and BEV. The availability of only 18 EV places in a city center and the fact that 14 of them were occupied by ICE vehicles was not an anomaly, but rather the norm in many urban and suburban areas. The need to “have a place to connect the car” was an almost indispensable prerequisite to fully exploit the efficiency potential of a vehicle like the hybrid X5, effectively relegating the optimal PHEV experience to those who had access to a domestic charging. Eight years later, the landscape has radically changed. Global investment in charging infrastructures has exploded, driven by pro-electric government policies, increasing demand for electric and hybrid vehicles, and the entry of new actors in energy and technology. We have witnessed an exponential increase in the number of public charging points, both alternating current (AC) and continuous current (DC) ultra-fast. Highways and main road arteries are now scattered with charging stations that can recharge a vehicle in much shorter time than 2016. Companies like Electrify America, Ionity, EVgo and a myriad of local suppliers have created networks that extend for thousands of kilometers. Even the problem of “ICEing”, although not completely eradicated, has become less frequent thanks to a greater awareness, fines and increased availability of settlers. However, the challenges persist. The coverage and density of infrastructures still vary significantly from region to region. The charging speed has become a new technological battlefield, with vehicles requiring ever greater powers and stations that must be able to deliver them reliably. The interoperability between different charging networks and the ease of use of apps and payment systems are still areas requiring improvements. For PHEV vehicle owners, domestic charging remains the most convenient and efficient option. The installation of a wallbox or an upgraded outlet at home transforms the garage into a “personal service station”, making night charging a simple and advantageous habit, maximizing the kilometres run in electric mode and drastically reducing fuel costs. For those living in apartments or condominiums, access to charging remains a more complex challenge, requiring innovative solutions such as road charging or shared underground parking. The evolution of infrastructure is not only a matter of quantity, but also of intelligence. Network management systems, bidirectional charging (V2G – Vehicle-to-Grid) and integration with renewable energy sources are the next borders. The X5 xDrive40e highlighted how important the charging for PHEVs was, and its legacy is clear: the real efficiency of an electrified vehicle is inherently linked to the availability and accessibility of a robust and easy to use charging infrastructure. The road is still long, but the steps made since 2016 were gigantic, transforming charging from an insurmountable obstacle to a fundamental pillar of future mobility.
Electric Guide Dynamics: The “Piacere di Guidare” in the hybrid era
The BMW X5 xDrive40e’s driving experience in 2016, as described in the original article, was a first taste of how BMW’s “picere of driving” evolved into the era of electrification. The text emphasizes how the vehicle, while being heavy (over 2,300 kg), “weared well its weight”, thanks above all to instant pair of the electric motor. This feature, which provides 250 Nm of immediate push, is a distinctive feature of all electrified vehicles and represents one of the major changes in driving dynamics. The absence of delay in the response of the accelerator and the linear progression of the power radically transform the feeling of acceleration, making it more fluid and, for many, more pleasant, especially in city traffic or in rapid manoeuvres. The “seeing the needle of cashiers remain fixed at zero” during a “even brilliant” start is a feeling that at the time was reserved for a few pioneers, but that today became familiar to millions of drivers. However, the original article also highlighted some gaps, such as the steering wheel “inerte” and the poor “communication” with the front wheels. This criticism, recurring in many modern cars that have abandoned hydraulic systems for electromechanical ones, highlights BMW's challenge to translate its legendary driving feedback in an electrified context. Electric steering systems offer advantages in terms of fuel efficiency and ease of integration with driving assistance systems, but often sacrifice the purity and “sensation” that purists love. In the following years, BMW and other manufacturers have worked hard to refine these systems, using increasingly sophisticated algorithms to simulate more natural and engaging feedback. The integration of electric motors has also allowed greater flexibility in the distribution of the torque, leading to integral traction systems such as the xDrive that can react almost instantly to optimize grip and stability. The regenerative braking is another key element that influences the driving dynamics of hybrid and electric vehicles. If well calibrated, it can make driving more efficient and comfortable, reducing the need to use mechanical brakes and prolonging their useful life. However, imperfect calibration can result in an unconsistent or unnatural braking sensation. The X5 xDrive40e offered different driving modes (Comfort, Sport, Eco Pro), which modified the accelerator response, suspension stiffness and gearbox logic, trying to offer a range of experiences suitable for different moods. This approach has been refined in successive generations, with greater customization and a smoother transition between modes. The challenge remains to maintain Sports DNA bMW, combined with a high-level driving comfort, while integrating the complexity of electrified powertrains. The “gravity center appropriate for an SUV” mentioned in the original article remains a physical reality, but innovations such as adaptive pneumatic suspensions and anti-roll systems have allowed to mitigate the effect of ground height, improving stability and maneuverability. Ultimately, the X5 xDrive40e has shown that the hybrid drive is not in contrast with the pleasure of driving, but rather transforms it, introducing new dimensions such as the silent handling, the prompt response and the gratification of intelligent efficiency. His legacy is a precious lesson on how to adapt and reinvent the identity of a brand in an era of profound technological change.
Living with a PHEV: Economy, Ecology and Daily Possession Challenges
Owning and driving a plug-in hybrid (PHEV) like the BMW X5 xDrive40e implies a delicate balance between economy, ecology and daily challenges that emerge from the interface between two different sources of propulsion. The original article emphasised a crucial aspect: the combined EPA efficiency of 24 mpg (about 9.7 km/l) was difficult to replicate in reality without constant charging, with a test experience that did not exceed 22.2 mpg (9.4 km/l) of average. This discrepancy between approved values and real consumption is one of the most common criticisms addressed to the PHEV and largely depends on the driver's behavior and access to charging. If an owner does not frequently charge, the vehicle will operate mainly in hybrid or purely petrol mode, bringing fuel consumption to similar levels or, in some cases, higher than a comparable internal combustion vehicle, due to the additional weight of the battery and electric motors. However, if the PHEV is regularly recharged, as suggested by the original article for “short commissions at the grocery store”, the benefits become obvious. The possibility to travel between 20 and 80 kilometers (depending on model and generation) in purely electrical mode means that many daily movements can be made at zero cost of fuel and with zero direct emissions, significantly reducing the individual carbon footprint. The tax incentives, as the US$4.668 tax credit mentioned for the X5 xDrive40e, played a key role in making PHEV economically competitive at the time of purchase. These incentives, although varying according to country and year, were essential to fill the initial price gap due to technological complexity and the cost of batteries. Over time, the amount and availability of these incentives have changed, reflecting government policies and market maturity. From the ecological point of view, the PHEV offers a valid compromise. Although they are not “zero emissions” like pure electric vehicles (BEV) when the thermal engine is in operation, they still reduce overall emissions compared to traditional vehicles, especially when loaded from renewable energy sources. Battery production and disposal remain important environmental considerations for all electrified vehicles, but the industry is making progress in recyclability and sustainability of the supply chain. The daily challenges of possession of a PHEV include the need for charging planning. While BEVs require greater attention to the autonomy and location of charging stations for long trips, PHEVs offer the flexibility of the combustion engine as a “security network”. However, to maximize efficiency and savings, the owner must develop the habit of connecting the vehicle whenever it is parked, both at home and at the workplace or in public charging points. This requires a change of mindset compared to the simple “resupply when the tank is almost empty”. In addition, the cost of electricity varies considerably depending on the region and the time of the day, affecting the actual cost per kilometre route in electric. The maintenance of a PHEV is more complex than an internal combustion vehicle due to the presence of two propulsive systems, but on the other hand, the lower use of the gasoline engine for short routes can reduce the wear of some components. In summary, living with a PHEV is an experience that requires a certain commitment, but that rewards with greater efficiency, potentially lower management costs and a tangible contribution to the reduction of environmental impact, positioning itself as a fundamental intermediate step towards a completely sustainable mobility.
Design and Functionality in the Hybrid Abdence: Innovation and Comfort
The cabin of a vehicle, especially in a premium SUV like the BMW X5 xDrive40e, is much more than a simple driving space; it is an environment that has to balance aesthetics, ergonomics, functionality and comfort. In 2016, the hybrid X5, while maintaining the internal architecture familiar to the combustion models, had to integrate new features related to its electrified nature without compromising the experience of luxury and practicality. The original article praised the ergonomics “good” and the “dominant view” from the driving position, characteristics appreciated in the SUVs. But what really struck was the “glass-openable roof mass”, which flooded the cabin of light, contributing to a feeling of space and airyness. A seemingly minor but significant element for the author was the wood finish “almost like river wood”, which added a touch of warmth and distinction to the interior, demonstrating the importance of details in premium vehicles. The integration of hybrid technology has led to challenges and opportunities for interior design. The need to accommodate the battery pack from 9 kWh has slightly reduced the volume of the trunk compared to the models X5 not electrified, from 650 liters to 500 liters with the seats raised. Despite this, the 500 liters offered were still “a lot of space”, demonstrating that the builders could integrate the batteries without sacrificing excessively the functionality typical of a SUV. The division of the rear hanger in two pieces, with the lower part that bends to create a load shelf, is an example of how practical design can improve usability, regardless of propulsion. Energy management has become a new priority. The BMW iDrive system, with its wheel and surrounding buttons, has been adapted to display the energy flow, battery charging status, electric autonomy and hybrid system efficiency. Digital or hybrid instruments (analogs with digital screens) have begun to show new metrics, helping the driver understand and optimize energy use. The article also mentions how the X5 navigation app “made not only traffic but also topology and other information to maximize travel efficiency”, anticipating the ever deeper integration between infotainment and energy management. In the following years, this trend has increased. Hybrid and electric vehicles have driven innovation in the interior with larger and customizable screens, advanced voice commands and increasingly sophisticated connectivity. The instrumentation has become completely digital, offering graphics dedicated to electric drive, tips for efficient driving and a clear display of residual autonomy. Sustainable materials, innovative coatings and customization options have become increasingly important in the premium segment, reflecting increasing attention not only to luxury but also to environmental responsibility. The seats, as noted in the original article for the hybrid X5, continued to be an area of evolution, with the introduction of more ergonomic design, massage functions, ventilation and, in some cases, a greater lateral containment capacity to support dynamic driving. In summary, the design and functionality of the hybrid SUV cabin, starting with pioneers such as the BMW X5 xDrive40e, have shown that the integration of new technologies can take place without sacrificing comfort and practicality, but indeed, enriching the experience on board with new information and customization skills, creating an environment that is both luxurious and technologically advanced, a true sanctuary of modern mobility.
More than 2016: What Preserves Future for Hybrid SUVs and Premium Mobility
The introduction of the BMW X5 xDrive40e in 2016 provided us with a snapshot of a future that, eight years later, is already partly our reality. Looking beyond 2016, we are faced with an ever-changing panorama for hybrid SUVs and, more generally, for premium mobility. The role of PHEV, though fundamental as “bridge” towards full electrification, is destined to transform itself. New generations of plug-in hybrid SUVs are expected to offer even greater electric cars, with battery packs that could exceed 20-30 kWh and allow real autonomy in electric mode of 100-150 km, making them even more effective for most daily movements. This will further reduce the dependence on the internal combustion engine, which will increasingly assume a role of “range extender” for long trips. The efficiency of the thermal motor itself will continue to improve, with increasingly advanced combustion technologies and the integration of mild-hybrid 48V systems that will optimize its operation even when the electric motor is inactive. Battery technology is another area of incessant innovation. It is expected to adopt solid state batteries, which promise greater energy density, faster charging times, greater safety and longer life. These advances will be crucial to reduce the weight and bulk of battery packs, allowing designers greater freedom and further improving the driving dynamics of electrified SUVs. Artificial intelligence and connectivity will play an increasingly central role. Energy management systems will become even more sophisticated, using real-time data on traffic, topography, weather and even driver driving behaviour to optimize the use of electricity and fuel. The vehicle- infrastructure communication (V2I) and vehicle-vehicle (V2V) will allow hybrid SUVs to dialogue with the charging network and other vehicles for even more efficient energy management and to enable advanced autonomous driving functions. Customization and experience on board will be high at new levels. The cabin will become an integrated digital ecosystem, with holographic screens, intuitive user interfaces based on augmented reality, and entertainment and productivity capabilities that will turn the time spent in the car. Sustainability will become an even more decisive factor, with the use of recycled materials and biological origin, low-emission production processes and an ethical supply chain for the raw materials of the batteries. For premium manufacturers like BMW, the brand positioning will move more and more from the exclusive power of the engine to the ability to offer a holistic mobility experience, including sustainability, cutting-edge technology, unparalleled comfort and, of course, the pleasure of driving. While fully electric vehicles become more and more the norm, plug-in hybrid SUVs will continue to maintain their relevance to a specific audience that appreciates flexibility and gradual transition. They could also evolve into more extreme forms, such as high-performance hybrids or vehicles that also integrate hydrogen fuel cells to further extend autonomy and reduce supply times. The X5 xDrive40e lit the spark; the future will see this spark turning into a fire of innovation that will completely redefine the category of premium SUVs and our entire concept of mobility.
In retrospective, the BMW X5 xDrive40e, tested by Ars Technica in 2016, emerges not only as a charming and functional SUV, but as an authentic precursor of one of the most significant changes in the automotive industry. What was then a vehicle that “has fascinated us more than we expected” has become a symbol of BMW’s ingenuity and far-sightedness to embrace electrification. It has shown that it was possible to instill new life to a consolidated segment, offering consumers a practical and economically sensible way to greater sustainability without sacrificing luxury or performance. Its initial challenges, from real efficiency linked to charging infrastructure availability, were not insurmountable obstacles, but rather learning stages that led the entire industry to improve. Since its launch, we have witnessed an explosion of innovation: doubled electric autonomy, ultra-fast charging systems, deep digital integration and increasing environmental awareness. The X5 xDrive40e was not the end, but the beginning of a trip, a journey that continues to define the future of premium SUVs and mobility. Its legacy is clear: it opened the way to a new generation of vehicles that not only transport us, but connect us to a cleaner, more efficient future and, ultimately, even more electrifying.
