Fleet Advantage, an innovator in specialty financing, fleet data analytics, asset performance services, and life cycle cost management, released updated findings from its Truck Life Cycle Data Index (TLDI), which compares all-in operating costs of Class-8 trucks across recent model years. The price of diesel has made headlines recently, with the average price now at $6.40 per gallon; the data underscores the severe and growing financial consequences for organizations operating older model-year equipment.
The latest TLDI evaluates model year (MY) 2022 through 2026 sleeper trucks versus new 2028 MY equipment. According to the data, upgrading from a 2022 MY sleeper to a 2028 MY model can save organizations $12,655 per vehicle in the first year. For a fleet of 100 trucks, these savings scale to $1,265,500. The TLDI figures do not include adjustments for the upcoming EPA mandate.
Diesel prices have climbed steadily since Fleet Advantage last released its TLDI in April, when the national average stood at $5.47 per gallon. As fuel prices rise, the cost gap between older, less-efficient equipment and newer, more fuel-efficient trucks continues to widen, placing additional financial pressure on organizations running aging assets. Fleet Advantage’s TLDI data shows the compounding cost advantage of newer equipment across fuel efficiency and total all-in cost.
Diesel & Fuel Breakouts
Fuel economy continues to represent a major portion of the savings available through truck replacement. Based on the TLDI, organizations running 2022 MY sleepers can save $12,818 per truck in fuel alone in the first year following replacement with a 2028 MY truck, a 16% reduction in fuel expense with corresponding CO2 savings. The first-year fuel cost for a 2028 MY truck is $66,057, compared with $78,875 for a 2022 MY truck. At $6.40 per gallon, even incremental improvements in fuel efficiency translate into thousands of dollars in annual savings per truck, significantly accelerating return on investment timelines.
Why Q4/26 is the Optimal Time to Order
The TLDI figures do not include EPA mandate adjustments, but the upcoming EPA timeline makes the timing of a truck order as important as the decision to upgrade. Fleet Advantage compared three acquisition scenarios for an organization replacing 100 model-year 2022 trucks with 2028 MY equipment, based on when the order is placed:
| When Trucks Are Ordered | Equipment and EPA Impact | Total Savings Across 100 Trucks |
| Q4/26 | Order now at a 2028 MY truck cost with no EPA penalty and no added cost for the newer engine | $1,265,500 |
| Q1/27 & Q2/27 | Noncompliant engine trucks, with an EPA penalty of approximately $7,000 per truck | $968,800 |
| Q3/27 & Q4/27 | Compliant engine trucks, with a cost of approximately $12,000 per truck | $852,000 |
Ordering in Q4/26 allows organizations to lock in the full savings and avoid both the added expense of the newer engine and the penalties imposed by the EPA timeline, even at a slightly escalated OEC. With Q3/26 now closed, Q4/26 is the best remaining opportunity. Organizations that wait until H1/27 will incur a penalty, but will still realize savings. Those that wait until H2/27 will gain a compliant engine, but will incur the extra cost. In total, organizations that delay could lose more than $410,000 in potential savings per 100 trucks.
Availability will vary by manufacturer. Some OEMs will not offer noncompliant trucks later in the timeline, while others will, so organizations should confirm their options in addition to evaluation of alternative fuel vehicles, before assuming a future order will be available on current terms.
“Choosing when to order trucks and what type of truck are two of the most consequential decisions an organization will make this decade,” Brian Antonellis, senior vice president of fleet operations for Fleet Advantage, said. “With diesel at $6.40 per gallon and an EPA timeline that makes every quarter of delay more expensive, organizations cannot afford to make this call on instinct or incomplete information. The difference between ordering in Q4 2026 and waiting until late 2027 is more than $410,000 for every 100 trucks. That is why it is so important to have the most accurate data, a clear understanding of how engine compliance, penalties and fuel efficiency work together, and what alternative fuel vehicle options are available for a company’s specific application before making a procurement decision.”
Multi-Year Planning
A multi-year procurement plan is essential to optimizing equipment acquisition and reducing total cost of ownership (TCO). Paired with advanced data analytics, a proactive strategy gives organizations the fleet performance insights and market intelligence needed to make smarter, better-timed acquisition decisions, particularly when regulatory changes and volatile fuel prices are reshaping the economics of every order.
“Ultimately, a well-crafted procurement plan based on proven analytics leads to significant cost savings, improved operational efficiency, and a more competitive asset management strategy,” Antonellis said. “The data says the window is open right now, but it is closing.”
