Every vehicle in a fleet is the subject of a decision, whether anyone deliberately makes it or not. It can be kept for another year, replaced with something better suited to the work or released altogether. As next year's budgets take shape, that decision moves from the background to the foreground, and the quality of the answer depends almost entirely on the quality of the evidence behind it.
For many organisations the default has quietly shifted towards keeping. As reported by Fleet News, analysis by Licence Check found that four or five-year fleet leases are now typical, with longer business contract hire agreements costing 10-15% less than shorter ones. Longer cycles can be exactly the right call. They become the wrong one when a vehicle is kept by default rather than by design, and fleet asset management is the discipline of telling the two apart.
Why the Default Answer Is Changing
The shift is visible across car and van fleets alike. Research for the Fleet200, reported by Fleet News, put the average car replacement cycle at 48 months, two months longer than in 2021, even as annual mileages fall. Van operators have gone further. Speaking to Fleet News earlier this year, AFP chair Paul Hollick said fleet managers had found replacement cycles could be stretched to lengths that "would previously have been considered unimaginable".
None of this is a problem in itself. A longer cycle simply moves risk from one column to another. Depreciation slows, while service, maintenance and repair costs rise and the likelihood of unplanned time off road increases. Whether the trade works depends on the individual vehicle, which is why fleet asset management treats every vehicle as its own case rather than applying a single cycle across the whole fleet.
The organisations that extend cycles well tend to share one habit. They watch each vehicle closely enough to recognise the moment it stops paying its way. In its analysis for Fleet World, Licence Check stressed the need to track actual maintenance spend and highlight vehicles with abnormal repair frequency as cycles lengthen.
The Evidence Every Vehicle Leaves Behind
Three signals do most of the work in fleet asset management, none is conclusive alone. Read together, they usually make the answer clear.
Repair spend that keeps climbing
The first signal is the shape of a vehicle's repair spend over time. A steady line is reassuring. A curve that steepens year on year is the clearest sign a vehicle is approaching the end of its economic life. Wider pressures make that curve steeper than it used to be. As reported by Fleet News, analysis of more than 20,000 warranty repairs by WSG recorded a double-digit rise in repair costs, with cars aged four to seven years accounting for a disproportionate share of the increase.
A complete vehicle maintenance history turns that curve into something the fleet team can see. Every job, part and invoice recorded against the vehicle through workshop and inventory management shows not only what a vehicle costs but how often it returns with the same fault. Repeat defects are often the earliest indication that a vehicle has moved from maintenance into decline.
Utilisation that quietly falls
The second signal is use. A vehicle can be mechanically sound and still fail to earn its place if the work it was bought for has moved elsewhere. Telematics records how many days each vehicle is used and how far it travels, which makes a gradual decline visible long before anyone notices it informally. Falling use is the signal fleet asset management most often misses, because a quiet vehicle generates no complaints.
Time off road
The third signal is availability. A vehicle that spends more days in the workshop each year is costing more than its repair bills suggest, because the work it should be doing is either delayed or covered by hire. The live fleet availability view in Prolius shows which vehicles are operational, in the workshop or awaiting parts, and the history of that status becomes one of the most telling lines in any fleet asset management review.
Keep
In fleet asset management, keeping is the right answer when the evidence is calm. Repair spend is stable, utilisation is healthy and time off road is low. In those circumstances, extending a cycle spreads the cost of the vehicle over more productive years, and the Fleet200 research notes that outright purchase fleets can use that flexibility to hold vehicles when residual values are weak.
A kept vehicle still needs a plan. Servicing should be scheduled around its known workload through fleet maintenance and vehicle planning, and its signals should be reviewed again at the next budget point. Keeping is a decision with a date attached, not an absence of one.
Replace
Replacement is the right answer when the work still needs a vehicle, just not this one. The pattern is familiar: utilisation stays high while repair spend accelerates and time off road grows. The vehicle is in demand and increasingly unable to meet it.
Commercial Motor's recent coverage illustrates the logic in practice. Evolve Haulage, for example, has replaced older vehicles with 14 new tractor units expected to cover 190,000km a year each. At that intensity of use, reliability is worth more than the savings of an extra year on an ageing unit.
Knowing when to replace fleet vehicles also means comparing like with like. The whole life cost of keeping an older vehicle, including repairs, downtime and hire, should sit alongside the full cost of its replacement rather than the monthly rental alone. Effective fleet asset management makes that comparison routine rather than exceptional.
Release
Release is the answer most often overlooked in fleet asset management. When utilisation has fallen and the work has moved on without it, replacing the vehicle like-for-like simply renews a cost the organisation does not need. Releasing it removes that cost entirely.
Before a vehicle goes, it is worth asking whether another site or team could use it. Redeployment can fill a genuine gap elsewhere and avoid a new acquisition. Where no such gap exists, release frees budget for the vehicles that are working hard, and fleet asset management shows exactly which those are.
One Record, One Decision
Each fleet asset management judgement relies on information that, in many organisations, lives in different places. Repair invoices sit with the workshop or finance team. Telematics data sits in a separate portal. Availability is tracked on a whiteboard or a spreadsheet. Assembling them for every vehicle at budget time is slow and often incomplete.
Vehicle management software that holds the full vehicle lifecycle in one record removes that burden. Prolius links workshop history, cost, utilisation and availability to each vehicle from the day it joins the fleet. Fleet cost management shows spend against budget, while fleet management reporting ranks vehicles by the signals that matter, so a vehicle replacement shortlist can be drawn from evidence rather than age alone. Good fleet lifecycle management then becomes a routine part of the year rather than a scramble before each budget.

Get in Touch
The right vehicle at the right time is rarely a matter of luck. It is the result of fleet asset management that reads each vehicle's evidence and acts on it, keeping what still performs, replacing what has started to struggle and releasing what the work does not need.
Prolius brings the data behind fleet asset management together for every vehicle, from maintenance and workshop history to telematics utilisation, availability status and budget performance, giving fleet teams the evidence to make each decision with confidence.
