MAN TGX

The TGX is the series MAN assigns to long-haul and heavy-duty transport in the truck generation it launched in February 2020 — which MAN called its first completely newly developed truck generation in 20 years.

Overview and generations

MAN presented the new truck generation — TGL, TGM, TGS and TGX — in February 2020. Its launch release names the MAN TGA, presented in 2000, as the series this generation follows, and says MAN would keep offering the previous models “during the transition phase until the end of 2020”. In that release the TGX covered 18 to 41 tonnes gross vehicle weight, with a 250-tonne gross train weight possible for heavy-duty applications.

At launch MAN gave the TGX three engine series: the D38 with up to 640 hp, the D26 from 430 to 510 hp and, for light long-haul transport, the D15 from 330 to 400 hp. It described them as the Euro 6d engine range introduced in 2019, and put the new generation’s fuel saving at up to eight percent against the Euro 6c predecessor version in classic long-haul transport (MAN’s claim). Alongside 4x2 and 6x2 semitrailer tractors and chassis, the 6x4 and 8x4 variants remained available, and the 4x2 semitrailer tractor could be ordered with MAN HydroDrive, a hydrostatic front-axle drive.

The TGX data sheet that MAN’s specifications page still links to (a file created in April 2023, according to its metadata) lists the same three engine series, with the D26 in three steps from 324 to 382 kW, and no D30.

For model year 2025 MAN presented the D30 PowerLion driveline in September 2024: the new D30 engine, the 14-speed TipMatic 14 gearbox, new disc brakes and aerodynamic changes, with equipment options orderable in stages from October 2024. MAN put the fuel-consumption reduction at up to 4 percent. Its September 2026 brochure states the same “up to 4%” for a long-haul semitrailer tractor with the D30 PowerLion driveline against a previous-model vehicle without the listed features; MAN’s D30 page itself mixes “up to 4%” in some passages with “up to 5%” (and the technical table’s “up to -5%”) in others, against the D26 of model year 2024.

In the September 2024 release MAN said the D30 would replace the D26 and D15 in all its 4x2 semitrailer tractors in normal and low heights, and that the TipMatic 14 would in future replace the TipMatic 12 in all its standard semitrailer tractors in the heavy series. Its September 2026 brochure states the engine change in the present tense — the D30 “replaces” the D26 and D15 in 4x2 semitrailer tractors in normal and low design — and gives the gearbox a narrower scope than the 2024 plan: the TipMatic 14 is “only available for 4x2 semitrailer tractors with D30 engine in normal or low-design height”, and the twelve-speed gearbox remains the only one “for our chassis vehicles and some semitrailer tractors in different wheel drives”.

Other model-year 2025 changes MAN listed: a gross train weight display in the fully digital instrument cluster, a sound-insulating windscreen with a 0.81 mm acoustic interlayer, encapsulation of the D30 driveline, new interior colours, 16 standardised frame layouts for the 4x2 tractor in normal height and low design, combination tanks for diesel and AdBlue, and a redesigned front underride guard for normal-height vehicles with a bumper.

Cabs

MAN’s specifications page lists three wide cabs for the TGX, all 2,440 mm wide and 2,280 mm long: the GX (extra high), the GM (medium high) and the GN (standard height). MAN’s specifications page gives these figures:

	GX	GM	GN
Interior length × width	2,145 × 2,270 mm	2,145 × 2,270 mm	2,145 × 2,270 mm
Engine tunnel height	120 mm	120 mm	120 mm
Standing height on the engine tunnel	2,070 mm	1,860 mm	1,580 mm
Standing height in front of the co-driver’s seat	2,150 mm	1,940 mm	1,660 mm
Seats	2	2	2
Beds (max.)	2	2	1
Lower bed, length × max. width	2,000 × 800 mm	2,000 × 800 mm	2,000 × 800 mm
Lower bed width behind the seats	700 mm	700 mm	700 mm
Height above lower bed	790 mm¹	690 mm¹	1,025 mm
Upper bed, length × width	2,000 × 715 mm	2,000 × 715 mm	—
Height above upper bed	660 mm	570 mm	—
Roof storage compartments	48 l	48 l	48 l
Roof luggage rack	355 l	200 l	—
Rear storage boxes, left / right	234 / 292 l	234 / 292 l	234 / 292 l
Central storage below the bed²	219 l	219 l	219 l

¹ When equipped with two beds. ² Maximum values, depending on the configuration.

MAN’s brochure gives the GX more than 1,100 litres of stowage space in total, and describes a modular storage box under the bed that takes a fridge, a drawer or a storage compartment. The extended cab models have a multi-zone cold-foam mattress on a 7-zone slatted base with an adjustable head; a control panel in the rest area operates the lights, door locks, heating and windows. An independent electric air conditioning system, which MAN says works without a cold reservoir, and an auxiliary water heater are listed in the brochure.

The entrance sits in the middle of the door area, with a stair-type access ladder and entry lighting; MAN’s 2020 release gives a door opening angle of 89 degrees. MAN EasyControl places four buttons in the driver’s door that can be used from outside the vehicle. The brochure also lists a Vario passenger seat that folds away, and a steering wheel that tilts forward to a horizontal rest position.

Engines

All four engine series on MAN’s specifications page are six-cylinder in-line engines, ticked for the Euro 6 emission standard:

Engine	Displacement	Power steps, kW (PS)	Torque
D15 (D1556)	9.0 l	243 (330), 265 (360), 294 (400)	not given
D26 (D2676)	12.4 l	324 (440), 353 (480), 382 (520), 397 (540)	2,650 Nm in the 397 kW step (brochure)
D30 (D3066)	12.7 l	279 (380), 302 (410), 324 (440), 353 (480), 382 (520), 412 (560)	2,100–2,800 Nm
D38 (D3876)	15.2 l	397 (540), 427 (580), 471 (640)	2,700–3,000 Nm (MAN UK, May 2022)

D30. MAN’s D30 page gives the D3066 a best specific fuel consumption of about 169 g/kWh, “which corresponds to an efficiency of > 50%”. It runs without cooled exhaust gas recirculation; MAN gives its compression ratio as 23:1 against the D26’s 21:1, and its ignition pressure as about 250 bar against the D26’s about 220 bar. Exhaust aftertreatment is two SCR catalytic converters in series, and MAN states Euro 6e for the engine. MAN’s 19 September 2024 release gives the XPI common-rail injection as working at up to 1,800 bar with 10-hole nozzles. Two turbocharger geometries are used, one for 380 to 440 hp and one for 480 to 560 hp. MAN’s equipment page gives full torque “from just 900 rpm”. The brochure says the D30 is always combined with the TipMatic 14 two-shaft gearbox, twin SCR aftertreatment and a new hypoid axle portfolio.

D26. MAN’s equipment page lists two-stage exhaust gas recirculation and says the D26 “now meets the Euro 6e standard”, with power “increased (+ 20 HP to 540 HP)”. The brochure says the D26 in Euro VIe “brings 10 hp and 50 Nm more” and now has a peak rating of 540 hp (397 kW) with 2,650 Nm. MAN UK’s chassis specification of May 2022 lists the D26 at 430, 470 and 510 PS, the steps MAN also named at the 2020 launch.

D15. MAN’s brochure says the D15 does without EGR, using SCR and a CRT particulate filter, and that paired with the optimised axle drive its weight was reduced. The equipment page lists common-rail injection, simplified SCR aftertreatment, and less engine weight, “and consequently more payload”.

D38. The equipment page lists common-rail injection at up to 2,500 bar and two-stage turbocharging with intercooling. MAN UK’s chassis specification of May 2022 for the TGX D38 6x4 tractor lists the same three power steps (540, 580 and 640 PS) with 2,700, 2,900 and 3,000 Nm, a rated speed of 1,800 rpm, a displacement of 15,256 cc and a torque band from 900 rpm to 1,380 rpm (1,400 rpm for the 640 PS step). MAN calls the D38 engines “the powerhouse of the 250-tonne range, flanked by the MAN D26 and the new D30 engine”.

Service intervals. The brochure says the D30, D26 and D38 engines are designed for service intervals of up to 140,000 km, and that D30 PowerLion vehicles on MAN 3977 fully synthetic engine oil allow oil change intervals of up to 150,000 km.

Transmission

MAN TipMatic 14. Fourteen forward and two reverse gears, automated manual, with clutch actuation and gearshifts done by the gearbox. MAN’s D30 page lists 13th gear as direct drive and 14th as overdrive. The September 2024 release says it is around 60 kg lighter than the TipMatic 12, that six additional reverse gears can be activated over the air via MAN Now, and that it runs on MOTION gear oil of SAE class 75W. Per the brochure it is “only available for 4x2 semitrailer tractors with D30 engine in normal or low-design height”.

MAN TipMatic 12. Twelve forward and two reverse gears, automated manual; the brochure presents it “for MAN D26 engine” and as the only gearbox “for our chassis vehicles and some semitrailer tractors in different wheel drives”. MAN UK’s May 2022 chassis specifications list its ratios as 16.69 in first gear to 1.00 in twelfth (direct drive), with reverse ratios of 15.54 and 12.03, behind a single-plate clutch of 430 mm diameter.

The TipMatic is operated from the right-hand steering-column stalk. The brochure lists the functions SmartShifting, Idle Speed Driving and a rocking-free function, and the driving programs Efficiency, Manoeuvre, heavy loads and Performance. The MAN EfficientRoll gearbox function shifts to neutral on slight downhill gradients, with the engine at 550 rpm instead of the usual 600 rpm idling speed.

TraXon Torque. In MAN’s 250-tonne heavy-duty range the gearbox is the TraXon Torque with torque converter clutch (WSK).

Endurance brakes. Offered only with the D30 PowerLion driveline: the CRB compression release engine brake with up to 355 kW, and the decouplable Retarder 47 with up to 4,700 Nm braking torque. New engine-side and gearbox-side power-take-off ranges are likewise D30-only options. MAN UK’s May 2022 sheets list an exhaust brake among the engine features.

Axles, suspension and brakes

MAN’s TGX chassis table ticks five axle configurations: 4x2, 6x2 in two forms (MAN’s “6x2-” and “6x2”), 6x4, and a row MAN labels “8x4/ 8x4-”; its separate row for a plain 8x4 is not ticked. The brochure names the 8x4 variants an “8×4/4 chassis” and an “8×4/4 heavy-duty tractor”. The heavy-duty range is offered as 6x2, 6x4 and 8x4/4.

MAN’s equipment page lists the HY 1344 hypoid drive axle with a longer final drive ratio for long-haul transport, and MAN HydroDrive, the hydrostatic front-wheel drive, with a payload advantage MAN gives as 400 to 750 kg “compared to a common all-wheel drive”. For the heavy-duty semitrailer tractor from MAN Individual the brochure lists double-ratio planetary rear axles.

The brochure says the air-sprung rear axle is now standard in long-haul transport; full air suspension with four air bellows is optional, as is continuous damping control (CDC) for bodies with a high centre of gravity. The electronically controlled air suspension (VASC) raises and lowers the frame; its control can relieve a second rear axle, set a second lowered driving height, and operate the trailer’s air suspension. MAN offers the TGX in standard height, in a medium-height version with more ground clearance, and in an ultra-low version with a low frame upper edge.

Service brakes are pneumatically actuated disc brakes with internally ventilated discs. The version introduced for model year 2025, for vehicles of 18 tonnes gross weight or more, has a pad return system that pushes the pads away from the disc after release. The electronic brake system EBS includes ABS and anti-slip control (ASR); its active wheel speed sensors measure from 0.1 km/h, and its functions include a halt brake with rollback detection and the MAN EasyStart Offroad hill holder. The brochure also lists a Trailer Stability Brake.

MAN UK’s May 2022 chassis specifications (UK market) give these running-gear details:

	TGX 18.430–18.510 4x2 BL SA	TGX 26.540–26.640 6x4 BB SA
Front axle	Drop beam; single parabolic springs	Drop beam; two-leaf parabolic springs
Drive axle	Single reduction; electronically controlled air suspension	Single reduction, cross-axle and inter-axle differential locks; five-leaf parabolic springs
Axle ratio	2.31:1	3.08:1
Tyres	315/70 R22.5	315/80 R22.5
Brakes	EBS with ABS, disc brakes, spring parking brakes on the rear axle	EBS with ABS, disc brakes, spring parking brakes on the rear axle
Steering	Hydraulically assisted	Hydraulically assisted

The same sheets give the frame as bolted and riveted S500MC steel, 270 × 85 × 8 mm in section, 942–762 mm wide (waisted), and the electrical system as 24 V with a 110 A alternator and two 12 V 230 Ah batteries.

Dimensions and weights

MAN’s brochure describes the range as running “from a 4×2 semitrailer tractor to an 8×4/4 chassis or an 8×4/4 heavy-duty tractor with a total towing weight of up to 250 t”. MAN’s heavy-duty page says the heavy-duty TGX, such as the TGX 41.640 8x4/4 BB SA, is designed for gross train weights of 250 tonnes, “even more with special approval”.

MAN’s current TGX pages publish no chassis dimensions or weights. The figures below are from MAN UK’s May 2022 chassis specifications; the 4x2 sheet is for the D26 in its former 430–510 PS steps, and in 4x2 semitrailer tractors in normal and low design MAN’s September 2026 brochure says the D30 now replaces the D26.

	TGX 18.430–18.510 4x2 BL SA	TGX 26.540–26.640 6x4 BB SA
Wheelbases	3,600 / 3,900 mm	3,300 / 3,600 / 3,900 mm
Rear bogie spread	—	1,400 mm
Front overhang	1,475 mm	1,475 mm
Rear overhang	800 mm	700 mm
Fifth-wheel height, laden / unladen	1,223 / 1,253 mm	1,290 / 1,370 mm
Turning circle, wall to wall	14.8 / 15.7 m	18.5 / 19.3 / 20.1 m
Unladen weight (GN cab, full tanks, with driver, ±2.5%)	7,213 / 7,233 kg	9,921 / 9,943 / 9,965 kg
Gross vehicle weight	18,000 kg	26,000 kg
Front axle plate	7,500 kg	7,500 kg
Rear axle plate, design / UK legal	11,500 / 11,500 kg	21,000 / 19,000 kg
Gross train weight, design and UK legal	40,000 kg	44,000 kg

Both sheets note that 8,000 kg and 9,000 kg front-axle upgrades are available. The gross combination figure shown in the overview — 40 tonnes — is the 4x2 sheet’s gross train weight.

Tanks

The combination tanks introduced for model year 2025 hold diesel and AdBlue in a single tank with two separate compartments, the AdBlue chamber plastic-coated inside to protect the aluminium; the brochure says they are available only with the D30 PowerLion driveline. MAN’s September 2024 release gives the compartments as 690 litres of diesel and 165 litres of AdBlue; MAN’s D30 page says the combination tanks allow a fuel volume of up to 1,270 litres. MAN UK’s May 2022 sheets list a 400-litre rectangular steel fuel tank and a 60-litre AdBlue tank in standard specification.

Safety and driver-assistance systems

The brochure and the equipment page list these systems for the TGX; where a document marks a system as standard or as part of a package, that is noted:

• Emergency braking: MAN Emergency Brake Assist (EBA Advanced) detects vehicles, pedestrians and cyclists and can brake to a standstill; the equipment page says it detects crossing vehicles and vulnerable road users in accordance with UNECE R 131. FrontDetection Plus monitors the area ahead when moving off and at low speeds and can brake automatically.
• Turning and lane changes: MAN Turn Assist (radar monitoring of the co-driver’s side, with automatic braking); Lane Change Support, whose radar monitors from 50 km/h up to about 30 m to the front and about 80 m to the rear; Lane Change Collision Prevention Assist with corrective steering; the side camera system (SCS) and Video Turn Assist, which detects objects in an area of 2.5 m × 6 m to the right of the vehicle (both “MAN Individual package” in the brochure).
• Lane keeping: Lane Departure Warning, “available on demand in a version that cannot be switched off”, and Lane Return Assist.
• Automated longitudinal and lateral control: ACC Stop&Go, the traffic jam assist, and the long-haul assistant MAN CruiseAssist, which controls driveline, brakes and steering on motorways and similar roads; the equipment page says CruiseAssist and MAN SafeStop Assist are available for the TGX.
• Driver state: the MAN Driver Monitoring System (AttentionGuard), a camera in the A-pillar that assesses gaze direction and eye opening; the brochure says it complies with the requirements for new vehicle registrations from July 2026. MAN SafeStop Assist brakes the truck to a standstill if the driver no longer steers, unlocks the doors and switches on the interior lighting.
• Other systems: distance warning, traffic sign recognition (camera and, with navigation, map data), high-beam assist, driver’s airbag with belt tensioner, rear side area monitoring with exit warning, the Reversing Motion System camera ex works, MAN BirdView 360° camera (“MAN Individual package”), MAN ComfortSteering, and preparation for an alcohol interlock. The tyre pressure monitoring system with tyre temperature display is, in the brochure’s words, “as standard available for the entire range up to and including 4-axle vehicles”.
• MAN OptiView: a digital mirror-replacement system with five cameras — near-range and wide-angle cameras on each side above the door frame and one on the co-driver’s A-pillar replacing the front mirror — and displays near the A-pillars. A version with a conventional front mirror is also offered.

MAN EfficientCruise with PredictiveDrive, the GPS-based cruise control, reads the topography up to three kilometres ahead; the brochure says it works from about 30 km/h and offers four ECO levels for the permitted deviation from the set speed.

Equipment and options

• Cockpit: a fully digital instrument cluster with a 12.3-inch colour display, an electric parking brake applied automatically when parked, and a central button for the assistance-system menu. Notices can be played in 30 languages and voice commands are offered in six (brochure).
• Media systems: MAN’s specifications page lists six units — Navigation Professional 12.3 inches (1,920 × 720 pixels), and Navigation Advanced, Advanced, Medium, media system and radio SD card, each with a 7-inch 800 × 480 display. MAN SmartSelect, a rotary controller, can be combined with the top three; truck navigation is part of the two Navigation units.
• Body interfaces: electronic interfaces behind the front flap and behind the cab; MAN PAL lets body builders program parameters and function logic via the MAN ABBI portal, with up to 10 body functions assignable to the body keypad or the EasyControl keypad (2024 release). Up to two camera signals are processed as standard, and up to five cameras can be connected via a camera hub. The Splitter Box Adjustment for gearbox PTOs is available only on D30 semitrailer tractors.
• Aerodynamics: reversible extensions on the side flaps and roof spoiler, A-pillar cladding, door gap closing elements, and — only with the D30 PowerLion driveline — frame skirts and underbody panelling.
• Individual versions: MAN Individual offers the heavy-duty semitrailer tractor for gross train weights of up to 250 tonnes and the TGX Individual Lion S trim with carbon exterior accents, red interior details and Alcantara.

Source notes

MAN UK’s May 2022 chassis specification for the D38 6x4 tractor (TGX 26.540 to 26.640 6x4 BB SA) gives a gross train weight of 44 t, under both “Design” and “UK Legal”, against the 40 t of the 4x2 shown above. The D26 peaks at 2,650 Nm in its 397 kW step; the documents cited give a D26 torque range only for its former 430–510 PS steps (MAN UK, May 2022), so none is shown. MAN’s heavy-duty TGX, such as the TGX 41.640 8x4/4 BB SA, is built for “a total towing weight of up to 250 t” (MAN, 09/2026) and is not covered by the gross combination figure above.
