And they’re off. MAN Truck & Bus South Africa has come out the 2026 starting gates running with powerful new offerings in the form of its new D26 Efficiency engine platform across the TGS and TGX heavy-duty ranges – with the launch of the TGX 26.520 6×4 truck tractor leading the rollout.
The move marks a significant upgrade to MAN’s regional product offering, combining a new engine generation with updated driveline components and expanded driver-assistance technologies aimed at improving fuel efficiency, safety and total cost of ownership.
New D26 engine platform
At the center of the update is the latest 12.4-litre MAN D26 inline-six diesel engine. The platform replaces the previous D20 and D26 engine families and is standardised across the range in three power ratings – 400hp, 440hp and 520hp – with torque outputs of up to 2 600Nm available from as low as 930rpm.
The engine features common-rail injection pressures of up to 1 800 bar, a single-stage turbocharger with an electrically actuated wastegate and MAN’s EVBec high-performance engine brake.
According to MAN, the combustion system has been redesigned to improve thermal efficiency, with compression ratios reaching 21.8:1 and ignition pressures up to 220 bar. Engineering updates such as steel pistons, anti-polishing rings and optimised bearings are intended to reduce friction losses and extend service life.
For Euro 5 applications the engine uses an updated SCR-only aftertreatment system with Euro-6-derived catalyst technology and airless AdBlue dosing to simplify emissions control and improve reliability.
Efficiency gains
MAN reports measurable fuel savings compared with the previous generation. In Euro 5 configuration, the new driveline is claimed to reduce fuel consumption by up to 3%, while Euro 2 variants can achieve improvements of up to 6% under comparable operating conditions.
These gains come from a fully integrated driveline package combining the new engine with the MAN TipMatic automated manual transmission and a newly developed hypoid rear-axle family designed for long-haul efficiency.
Updated driveline and safety systems
The MAN TipMatic 12-speed automated manual transmission is now standard across the heavy-duty range. Equipped with SmartShifting technology, it delivers faster and smoother gear changes while maintaining tractive force under load. Drivers can select from operating modes such as Efficiency, Efficiency+, Offroad and Heavy-Duty to adapt shifting behaviour to different operating conditions.
Complementing the transmission is MAN’s new hypoid axle generation featuring lighter housings, optimised bearings and longer final-drive ratios to improve fuel economy.
The updated electronic architecture also enables broader availability of driver-assistance technologies including Emergency Brake Assist (EBA and EBA Plus) with vulnerable road-user detection, Adaptive Cruise Control and Front Detection for monitoring pedestrians and cyclists at low speeds. MAN’s OptiView digital mirror-cam system is also available to enhance visibility during turning and maneuvering.
TGX 26.520 flagship
Leading the rollout is the TGX 26.520 6×4 BL SA, which pairs the 520 hp D26 engine with the TipMatic 12.26 Direct Drive gearbox and the new hypoid axle configuration.
The model is offered with MAN’s GM cab, which combines aerodynamic improvements with driver-focused ergonomics. Features include High-Beam Assist, rain-sensing automatic wipers and EBA Plus with pedestrian and cyclist detection.
MAN says the TGX 26.520 delivers strong tractive performance at low engine speeds while maintaining competitive fuel economy for long-distance freight operations.
The truck marks the first step in MAN Truck & Bus South Africa’s phased rollout of the D26 Efficiency platform, which will be progressively introduced across the full TGS and TGX product range during 2026.
The launch of these new offerings was announced at MAN ‘s recent media event where the company also introduced its newly structured customer-centric business eco-system under the banner of Drive360. In essence, the Drive360 represents MAN’s commitment to providing a complete 360-dergeee ecosystem of support for its customers – from initial vehicle specification to end-of life optimisation. It’s all the right stuff.
FleetWatch will be reporting further on all this in our next eMag due to hit your desks – or laptops, tablets, cellphones or whatever – very soon. Look out for it.
