EV adoption: 3 global trends in transition to mixed-energy fleets
Electric vehicle (EV) demand has steadily risen in the U.S., with total EV registrations up from 280,000 vehicles in 2016 to over 1.2 million in 2024. In August 2025, 172,049 Hybrid Electric Vehicles (HEVs) were sold in the United States (57,589 cars and 114,460 light trucks), up 14.2% from August 2024.
A study by business consulting firm Frost & Sullivan, commissioned by WEX, highlights plans for increased EV adoption. This is among commercial fleets globally that already operate a mix of internal combustion engine (ICE) and electric vehicles (EVs). According to the global survey, 80% of these fleet operators plan to electrify at least 25% of their fleet by 2030. Additionally, nearly 50% expect EVs will make up half or more of their fleet by the same time.

EV adoption: 3 key trends in the commercial vehicle space
To better understand the commercial EV adoption landscape, the researchers who conducted the study surveyed more than 500 commercial mixed-energy fleet operators. The survey was conducted across Europe, North America, and Asia-Pacific. Subjects’ fleets ranged in size from two to 500+, and each had at least one EV in their inventory.
These findings highlight several key trends driving the shift to mixed-energy fleets including:
- Operational efficiency is paramount during EV transition
- Streamlining charging and payments is essential in mixed-energy fleet adoption
- Smart digital solutions could help future-proof fleets looking to adopt EV
Trend #1: Operational efficiency is paramount during EV transition
Operations become complicated when business owners and fleet managers have to account for two very different vehicle models. This complexity means overseeing two routing systems, two fueling plans, and vastly different maintenance schedules.
Even when faced with electrification challenges, including high upfront costs (64%), 50% of surveyed organizations went ahead and invested in a charging infrastructure for their plant. The analysis is future forward: Invest in infrastructure now. Then you can realize future rewards as your hybrid and electric vehicles ultimately save you money down the line.
Trend #2: Streamlining charging and payments is essential in mixed-energy fleet adoption
Most organizations (78%) have on-site charging, but en route charging and at-home charging are also common. Having the same payment program for both ICE and EVs is a top priority. When adopting electric vehicles into your fleet, the question quickly becomes, “How do I manage this alternative form of fueling?” Finding a fuel card partner that can integrate electric vehicle charging into an existing fuel card program will be optimal. It will allow for a streamlined, manageable, mixed-energy fleet system.
Trend #3: Smart digital solutions could help future-proof fleets looking to go electric
For business owners and fleet managers building a mixed-energy fleet some aspects of the transition may feel challenging. These include route planning, data analysis, and integrating two unique vehicle demands into one system.
In Frost & Sullivan’s research, sponsored by WEX, more than half of survey respondents (58%) struggled with route planning. This struggle involves planning fueling station stops for two different types of fuel. This presents a unique challenge.
Range is also a factor when route planning. Data and reporting for a mixed-energy fleet also appears to be a challenge. Forty-nine percent of survey respondents struggled to collect data for their ICE and EV fleets.
Technology was also cited as a top challenge. Forty percent of respondents faced difficulty integrating fleet management software for both ICE vehicles and EVs. The best fuel card programs will offer a package deal. This includes routing, data analysis, and technology solutions that effortlessly blend the core components of a mixed-energy fleet.
Electric vehicle adoption insights: U.S. trends
In 2024, in the United States, EV sales increased to 1.6 million, and the sales share grew to over 10%. Also exciting for EV adoption in the U.S. was a 15% YoY increase in new EV models launched in 2024.
Cost savings with electric fleets in the U.S. market
In the U.S., 82% of organizations say cost savings is the main reason behind their decarbonization efforts. This makes the nation one of the most cost-driven markets surveyed. Government support and alignment at the CEO/board level are also top considerations, each cited by 76% of respondents. Cost savings can be found in fuel as well as reduced maintenance, making EV adoption a wise business decision.
EV charging stations and infrastructure challenges
U.S. fleets face significant challenges with proprietary charging hubs, including compatibility issues, limited access, and higher costs. Sixty-five percent of U.S. operators cited depot installation costs as the biggest hurdle. This refers to installing proprietary onsite charging stations. While the U.S. government has made great strides in building up a charging infrastructure across its roads and highways, there are still challenges to overcome.
According to Pew Research Center, the number of EV charging stations in the U.S. has more than doubled since 2020, which is great news. In December 2020, the Department of Energy reported that the number had grown to nearly 29,000 public charging stations across the country. In 2024, that number increased to more than 183,000 stations.
While more than 95% of the American public now lives in a county that has at least one public EV charging station, those in rural areas have limited access. Sixty percent of urban residents live less than a mile from the nearest public charging station. This is compared to only 41% of those in the suburbs who do. The number decreases in rural areas. Just 17% of those in rural areas have the same access to public EV charging as their suburban peers. While the U.S. is making strides in building out its infrastructure, there is still much work to be done to satisfy the needs of the majority of drivers.
Popularity of electric vehicle at-home chargers
American operators see real benefits to en route and at-home charging. However, 76% highlight the cost savings of at-home charging, with similar views in Australia (86%). For en route charging, convenience is key – 77% of U.S. operators value it for allowing employees to charge on the go, compared to 74% in the United Kingdom.
U.S. businesses understand that the most cost-effective way to charge their commercial EVs is by equipping their staff with at-home charging stations. This optimizes every aspect of the charging process while simultaneously saving the business money on the charge itself.
EV tools and technological challenges
Integrating software for both ICE vehicles and EVs is a major challenge for 49% of U.S. operators, similar to those in Germany (55%) and Australia (50%). As adoption in the U.S. grows, it’s likely the technology will develop in tandem. Finding a fuel card partner that will grow their EV solutions alongside your EV adoption will be a great first step when building your mixed-energy fleet.
Fuel card for both ICE and electric fleet management most sought after
Because of the challenges businesses face integrating ICE vehicles and EVs on a technical level, 55% of U.S. operators prioritize finding a fuel card that works seamlessly with their existing fleet management systems – more than in any other market globally. U.S. operators also want a fuel card they can use across both fuel and charging stations, with 59% reporting this as a critical aspect – again, higher than in any other market studied.
EV transition: We’re here to help
The transition to mixed-energy fleets is underway: 10% of light duty vehicles sold in the U.S. in 2024 were electric. While challenges to adopting EVs persist, the benefits are clear. From WEX’s research, we can see that organizations are actively seeking solutions to build their fleet into a mix of ICE vehicles and EVs and will continue to do so for the foreseeable future.
