Colin-on-Cars – N is for new

‘N’ stands for ‘new’ and JAC Motors has expanded the N-Series of trucks in South Africa with the addition of the N140 9-tonne powered by a Cummins 4,5-litre engine.

“A trademark of the N-Series is its excellent fuel efficiency across the range. The new N140 continues in that tradition,” says Karl-Heinz Göbel, Chief Executive Officer of JAC Motors South Africa. “Add to that its low cost of ownership, robust chassis design and durable drivetrain, and you have a truck suitable for various modern-day transport applications.”

The N140’s Euro 3, Cummins 4,5-litre ISB four-cylinder turbo-diesel engine produces 154 kW at 2 300 r/min and 740 Nm of peak torque between 1 200 r/min and 1 800 r/min. 

This powerplant features advanced fuel injection technology that delivers more power using less fuel, resulting in lower operating costs. Durability is also essential, and this engine includes wear-resistant components such as a cast-iron cylinder block and forged steel crankshaft, making it ideal for long-lasting use, minimising downtime and maintenance costs. 


Compliant with Euro 3 regulations, the turbo-diesel engine reduces harmful emissions, providing a greener option for operators looking to minimise their environmental impact while maintaining a high level of performance.

The N140 is paired with a synchromesh six-speed manual transmission and a hydraulic-assisted clutch. The drivetrain setup allows for low engine RPMs at cruising speeds, reducing fuel consumption.

“Cummins and JAC Motors have a 25-year successful relationship. In 2018, the two companies formed a joint venture, resulting in a number of our trucks being fitted with high-quality, clean and fuel-efficient engines with world-class technological and powertrain capabilities,” says Göbel.

The N140 has a heavy-duty ladder-frame chassis stamping and welding treatment process and sits on a front and rear semi-elliptical multi-leaf spring suspension providing better stability and less chassis roll in all load states and on any road surface.

The N140 supports a wheelbase of 5 300 mm and offers a payload of 9 000 kg. Its dimensions are 8 890 mm (L) x 2 348 mm (W) x 2 475 mm (H), making it suitable for various body applications.

The N140 features a Dual-circuit Air Brake system, including an Air Dryer, an anti-lock braking System and a Load Sensing Proportioning Valve (LSPV) for increased stopping power and driver control to prevent wheel lock-up under emergency braking conditions.

“The N140 offers the built-in flexibility of a chassis-cab design that allows for specific configurations based on unique transportation needs. With its powerful and fuel-efficient engine and robust suspension, it is suitable for various transport applications,” says Göbel.

The ergonomically designed cab has wider door apertures, footsteps and safety climbing handles that allow for easy entry and exit, which is less tiring for the driver and passengers. 

The reinforced cab floor increases driver protection, while the double rear-view exterior mirrors improve visibility. LED Daytime Running Lights, height adjustable headlights, a reverse warning buzzer, a seatbelt warning alarm and a tilt-and-telescoping multi-function steering wheel with radio and cruise control settings are all standard as are an air-conditioner, power windows, a 12V Accessory Power Outlet, and a radio with an MP3 player and Bluetooth, including a USB. 

“The N-Series appeals to a broad customer base across various industries. In our experience, customers want affordable, safe and dependable trucks to run and maintain. Trucks also need to offer comfortable and well-equipped cabins, must be economical and easy to operate,” adds Göbel.

The N140 9-tonne is available in chassis cab configuration. It offers the company’s two-year/unlimited km manufacturer’s warranty and 24-hour roadside assistance for peace of mind ownership. JAC Motors supports an extensive dealer network across Southern Africa and offers specialised service support and consistent parts supply to ensure minimum downtime.
