SINOTRUK HOWO-TX

The HOWO-TX is a heavy truck of SINOTRUK, sold under the HOWO name. On sinotrukinternational.com, Sinotruk’s international site, it heads the list of heavy trucks, beside the HOWO-MAX, HOWO-TS7, HOWO-NX, HOWO-T7H and HOWO-7, and its product page calls it “Un todoterreno en el ámbito de los camiones pesados” (an all-rounder in the field of heavy trucks) for long-haul logistics, regional distribution, special operations and construction work. This page is built from that one Sinotruk document, the HOWO-TX product page, in its Chinese version (read on 4 November 2026) and its Spanish and Russian versions (both read on 14 November 2026). The page is undated, and the three versions print the same tables.

Overview

No document opened gives a wheel formula, a launch date, a start of production, an emission class or an earlier generation of the HOWO-TX.

Cab

Sinotruk says the HOWO-TX cab is designed to raise the quality of the driver’s work and life. The page describes control buttons, instrument panel and displays laid out within easy reach, a steering wheel with pneumatic adjustment that can be set to any height and angle, an adjustable air-suspended seat with electric adjustment in several directions and lumbar support, and a sleeper berth. For all-round vision it lists a wide field of view, a four-direction monitoring system and an observation window, the last two marked as optional.

The cab table lists eight cab types with their main dimensions and berths.

Three further rows of the table print two values each, with no cab type beside them: the height from the lower to the upper berth, 625 mm and 640 mm; the upper berth width, 500 mm and 688 mm; and the height from the upper berth to the cab roof, 578 mm and 557 mm. TX-L and TX-U are the two cab types the table gives an upper berth. Cab types and berths in general are described in truck cabs explained.

Engines

The engine table lists seven in-line six-cylinder engines with their displacement and power. The power column is headed “Potencia (HP)” in the Spanish version, “功率/马力” (power/horsepower) in the Chinese and “Мощность/л.с.” in the Russian. No version gives a kilowatt figure, a torque, a rated speed, a fuel or an emission class for any of the engines.

Sinotruk presents the MC series as “la potencia premium exclusiva de SINOTRUK” (SINOTRUK’s exclusive premium power). It says the MC engines use a Bosch high-pressure common-rail system whose ECU controls fuel injection according to the engine’s operating state, at a maximum injection pressure of up to 1,600 bar, which it credits with finer atomisation, more power and lower fuel consumption. The cylinder block is of vermicular (compacted graphite) cast iron, which Sinotruk says is stiffer and stronger, allows thinner walls and lowers the engine’s weight; it gives the material 75% higher tensile strength, a 40% higher modulus of elasticity and 100% higher fatigue strength than traditional grey cast iron. The Chinese version adds a modular design: a fuel module that integrates the fuel pre-filter, hand pump, filter element and drain plug, and an oil module that integrates the oil filter, oil-gas separator, oil cooler and pressure-limiting valve, which it says lowers the risk of leaks. The MC13 family is described in Sinotruk MC13 engine, and how horsepower and kilowatt figures relate in reading truck power figures.

Gearboxes

Sinotruk says the HOWO-TX driveline was designed and optimised by matching its assemblies to one another, for a seamless delivery and efficient transmission of power. The gearbox table lists twenty-two gearboxes with the input torque each takes, its number of gears and its first-gear ratio. Of the HW series the page says that the main box uses twin countershafts and the auxiliary box planetary gearing, which it credits with simpler power take-off and gear shifting and with higher reliability and durability. The page does not say which of the gearboxes are manual, automated or automatic.

Allison’s transmission series are described in Allison automatic transmissions.

Axles, chassis and suspension

Sinotruk says the MC-series drive axles and the V-series steer axles of the HOWO-TX were developed from advanced German axles and improved to the latest technical standards, and credits them with higher transmission efficiency, improved heat dissipation, a higher load capacity and a longer service life. The final drive uses Oerlikon gears, whose strength the page gives as 10% higher, with no reference given for the figure. How final-drive ratios are counted is explained in axle ratios and final drive explained.

The HOWO-TX chassis is made of high-strength steel, and Sinotruk credits its frame with high resistance to compression, torsion and impact. The page says that several suspension configurations are offered, without naming them. No document opened gives an axle designation, rating or ratio, a suspension type or a brake type for the HOWO-TX.

Dimensions and weights

No document opened gives a wheelbase, an overall length, width or height, a kerb weight, a gross vehicle weight, a gross combination weight or a tank volume for the HOWO-TX. The page gives the cab dimensions listed under Cab.

Source notes

All figures are from one Sinotruk document in three language versions: the HOWO-TX product page on Sinotruk’s international site, sinotrukinternational.com, in Chinese (read on 4 November 2026), Spanish and Russian (both read on 14 November 2026). The page is undated, and the three versions print the same tables. It lists eight cabs, TX-M to TX-U, with their main dimensions and berths; seven in-line six-cylinder engines with displacement and power in hp only, and no kilowatt, torque, rated-speed, fuel or emission figure; and twenty-two gearboxes with input torque, number of gears and first-gear ratio. It gives no wheel formula, no axle designation, rating or ratio, no suspension or brake type, no wheelbase, no overall dimension, no weight and no tank volume, and no date of launch or of the start of production.
