Johannesburg, 2 October 2026 — Truck sales September 2026 data show the first stall in the commercial vehicle market this quarter. Heavy truck and bus sales slipped by 25 units to 2,204, according to naamsa figures reported by Business Day and The Rio Times on 1 October. Medium commercial vehicles rose 3.4% to 789 units. Together, that is 2,993 trucks and buses, which is one unit more than a year earlier.
The wider market told a different story. Total new vehicle sales rose 12.7% to 61,645 units, from 54,706 in September 2025. Passenger cars climbed 14.7% to 44,291, while light commercial vehicles gained 9.6% to 14,361. Exports, however, fell 18.8% to 31,473 units.
naamsa chief executive Mncane Mthunzi said the market closed the third quarter on a “remarkably resilient footing”, Business Day reported. He also named higher borrowing costs, renewed inflation pressure and weak growth as the backdrop. Over nine months, domestic sales reached 492,201 units, which is 12.5% ahead of 2025. Exports over the same period are down 10% at 281,458.
How Truck Sales September 2026 Compare With July And August
The slowdown is sharp. In July, medium commercial sales grew 19.4% and heavy sales grew 7.0%. In August, the gains were 16.3% and 10.1%. Then September brought 3.4% for medium trucks and a fall of about 1.1% for heavy trucks and buses. As the Desk’s August truck sales report noted, September was the first month to carry the full R2.93 diesel increase. The Reserve Bank then lifted the repo rate to 7.25% on 23 September.
Why Cars Grew While Trucks Did Not
Passenger demand has support that truck demand lacks. Rental companies took 13.8% of all September sales, while dealers handled 81.4%. Mthunzi also credited competitive pricing, financing offers and a wider choice of entry-level models. By contrast, a haulier buys a truck on what it will earn. Diesel is its largest running cost, and diesel is what rose most. So the two markets are responding to different pressures.
Analysis
What Truck Sales September 2026 Say About Fleet Renewal
One flat month is not a trend. Still, the timing matters. Hauliers placed September orders knowing that 50ppm diesel had passed R30 a litre and that October pointed higher. The Desk’s record diesel price report put the October projection near R33. In addition, prime moved to 10.75%. So an operator choosing between a new truck and another year from an old one now faces dearer fuel and dearer finance together.
The Desk Calculation: Diesel Against The Instalment
Here is the arithmetic, with the assumptions shown. First, the quarter. July, August and September add up to 2,437 medium trucks and 6,597 heavy trucks and buses, or 9,034 in total. Working back from naamsa’s growth rates, the same quarter of 2025 came to roughly 8,440. So the third quarter still grew about 7%, with medium trucks up about 13% and heavy trucks up about 5%. However, the prior-year monthly figures are implied from rounded percentages, so treat them as estimates.
Second, the new-truck sum. A R1.2 million truck financed over 60 months at prime of 10.75% costs about R25,900 a month. September’s R2.93-a-litre rise in 500ppm diesel, on 4,000 litres a month, added about R11,700 to the cost of running it. In other words, one month’s fuel increase equals about 45% of the instalment. By contrast, the September rate rise added only about R149 a month. Diesel, rather than interest, is therefore what moved the renewal sum.
Truck Sales September 2026: The Quarter Month By Month
| Month | Medium commercial | Heavy trucks and buses | Reading |
|---|---|---|---|
| July | 843 (+19.4%) | 2,243 (+7.0%) | Strong start, before the September diesel rise |
| August | 805 (+16.3%) | 2,150 (+10.1%) | Still growing, although diesel rose R1.38 |
| September | 789 (+3.4%) | 2,204 (about −1.1%) | Then growth stalled |
| Third quarter | 2,437 | 6,597 | Overall, still about 7% up |
The Numbers Behind Truck Sales September 2026
Fleet Impact
How Fleets Can Respond When Renewal Slows
When new-truck orders slow, fleets keep older vehicles working for longer. That shifts the pressure onto maintenance, fuel use and utilisation. So the question becomes whether each existing truck earns enough to justify its diesel. Vehicle tracking for fleet management shows kilometres, idle time and trips per vehicle, which reveals under-used trucks before a fleet buys another. Digit D-Fuel then compares the litres bought with the litres burned, so an operator can see what each truck really costs per kilometre.
- First, rerun the replacement sum. At about R25,900 a month for a R1.2 million truck, check whether lower fuel use and fewer repairs would cover the instalment.
- Second, measure utilisation before buying. If two trucks each stand idle for a third of the month, better scheduling may delay a purchase.
- Third, watch fuel per kilometre on older trucks. Consumption often rises as a truck ages, so a worsening figure is an early signal to replace.
- Finally, follow the next release. Truck sales September 2026 may prove a pause or a turn, and October’s numbers will show which.
Fleet Technology
Fleet Technology For A Longer Replacement Cycle
New-truck sales measure confidence. A fleet’s own data measures need. DigitFMS tracking logs each vehicle’s kilometres, idle hours and trips, so an operator can rank trucks by what they earn. Digit D-Fuel then sets the litres each one burns against the litres it took on. With both, the replace-or-keep decision rests on numbers rather than on age alone. Competing systems come from Cartrack, Netstar, Tracker, Ctrack and MiX by Powerfleet. However, DigitFMS backs its installations with more than 100 branches nationwide.

Questions Answered
Frequently Asked Questions: Truck Sales September 2026
How Many Trucks Were Sold In September 2026?
South Africa sold 789 medium commercial vehicles and 2,204 heavy trucks and buses in September 2026. That is 2,993 in total, or about 4.9% of the 61,645 new vehicles sold.
Did Truck Sales Fall In September?
Heavy truck and bus sales slipped by 25 units, or about 1.1%. Medium commercial sales rose 3.4%. Combined, the two segments were therefore flat, at one unit more than in September 2025.
Why Did The Car Market Grow While Trucks Stalled?
Passenger sales rose 14.7%, helped by rental buying, competitive pricing and financing offers. Trucks, by contrast, are bought on operating cost, and diesel rose sharply in September. Prime also moved to 10.75% late in the month.
How Did The Third Quarter End For Trucks?
Still ahead. Medium and heavy sales reached 9,034 units across July, August and September, which the Desk estimates is about 7% more than a year earlier. However, almost all of that growth came in July and August.
What Does A New Truck Cost To Finance Now?
On the Desk’s example, a R1.2 million truck over 60 months at 10.75% costs about R25,900 a month. September’s diesel increase added about R11,700 a month to running it, which equals about 45% of that instalment.
What Do Truck Sales September 2026 Mean For Hauliers?
Fleet renewal may be slowing as fuel and finance costs rise together. As a result, more fleets will run older trucks for longer. That makes fuel monitoring, utilisation data and maintenance planning more important until the October figures show whether the stall continues.
