In April 2025, a standard JAC T9 double-cab bakkie drove continuously for 24 hours at the Gerotek Testing Facilities near Pretoria — covering 4,084 km at an average speed of 170.1 km/h. In doing so, it broke a South African automotive endurance record that had stood for 15 years.
Most bakkie buyers never encounter durability claims this specific, this independently verified, and this directly relevant to the mechanical stress a commercial vehicle experiences over a long ownership life. Here is what the record actually proves — and what it does not.

What Gerotek Is — and Why It Matters
The Gerotek Testing Facilities near Pretoria are not a brand-owned track. They are a professional vehicle testing facility used by international automotive manufacturers for official vehicle development and certification testing. Tests conducted at Gerotek are independently witnessed and verified — the results carry institutional credibility that in-house manufacturer testing cannot provide.
When JAC submitted a T9 to a 24-hour endurance test at Gerotek, it was choosing the most credible independent testing environment available in South Africa. The record was not announced in a press release from a private event — it was achieved and documented at a recognised, professionally operated facility under witnessed conditions (source: carmag.co.za).
What Sustaining 170 km/h for 24 Hours Actually Stresses
A vehicle travelling at 170 km/h continuously for 24 hours is not experiencing normal driving conditions. It is experiencing:
Engine stress: Sustained near-maximum RPM operation for 24 hours tests thermal management, lubricant performance under high temperature, and component fatigue in a way that normal driving never approaches within a typical ownership period.
Cooling system stress: Engine, transmission, brake, and tyre temperatures at sustained high speed test the cooling system’s ability to manage heat across all operating components simultaneously.
Transmission stress: Maintaining gear selection at sustained speed tests gearbox synchroniser wear, fluid management, and mechanical fatigue.
Chassis and suspension stress: 24 hours of high-speed track banking and surface imperfections loads the chassis, suspension, steering, and wheel hubs in ways that accumulate structural stress rapidly.
Completing all of this without mechanical failure — on a production vehicle, not a specially prepared race car — is the most credible durability statement a manufacturer can make with a single test result (source: jacmotors.co.za).
What the Record Proves — and What It Does Not
What it proves:
– The JAC T9’s engine can sustain sustained high-load operation without failure across 24 hours
– The cooling, transmission, and chassis systems are engineered to handle mechanical stress beyond normal commercial use
– The platform’s structural integrity is sufficient to complete one of the most demanding endurance profiles possible in a production vehicle
What it does not prove:
– That every individual T9 produced is guaranteed fault-free — manufacturing variance exists across all vehicle brands
– That the T9 will never require warranty service — components still wear over time and kilometres
– That the T9’s reliability over 300,000+ km in commercial service is equivalent to a Toyota Hilux — the record tests sustained high-speed durability, not ultra-long-mileage commercial reliability
The honest reading: the Gerotek record provides uniquely strong structural and powertrain durability evidence at a level no SA bakkie competitor has produced. It does not provide a blanket guarantee — but it is the most credible single durability demonstration available in the SA bakkie market (source: cars.co.za).
Why This Matters for Bakkie Buyers
For SA bakkie buyers who have been conditioned to associate Chinese vehicles with unreliability — a perception that may have been accurate for first-generation Chinese exports a decade ago — the Gerotek record provides a factual, independently verified counter-reference. You do not need to take JAC’s word for their T9’s durability. You can reference a 15-year record broken under independently witnessed conditions at SA’s own professional vehicle testing facility.
