SITRAK C9H

The SITRAK C9H is a tractor unit in SINOTRUK’s SITRAK line. On sitrak.ru, the official site of SINOTRUK’s representation in Russia, run by Sinotrak Rus, the C9H page carries the banner “coming soon on sale” and calls the C9H the flagship of the SITRAK line. This page is built from that one Sinotruk document: the SITRAK C9H product page on sitrak.ru (Russian market, undated, read on 25 October 2026). The page links no PDF: no data sheet, brochure or manual.

Overview and status

Sinotrak Rus describes the C9H as “technology of a new level” in the SITRAK line and as an advanced tractor for regional and long-haul transport that brings together all the improvements of earlier models: an updated engine and axles, an extended set of comfort and safety features and intelligent driver-assistance systems. The page does not name the earlier models. The model menu on sitrak.ru lists the C9H tractors beside the SITRAK C7H MAX tractors and the C7H all-wheel-drive trucks, tippers, chassis and truck mixers. No document opened gives a date for the C9H’s launch or for the start of its sales in Russia.

The page says that the 4x2 wheel formula is available at present, and calls it the classic layout for long-haul and regional transport and the more popular one in the heavy-truck market. How wheel formulas are written is covered in axle configurations explained.

Cab

The C9H page offers one cab, the H, with two berths. Sinotrak Rus describes it as an ergonomic cab designed for long routes, with noise and heat insulation, a full rest area and plenty of storage space. The cab tab carries a table of thirteen dimensions in millimetres, in columns lettered A to M; the page does not say what each letter measures.

How high and low sleeper cabs differ in general is covered in truck cabs explained.

The page describes LED headlights, fog lamps and aerodynamic parts: a bumper, cab and chassis deflectors and bonnet cladding, whose shape it says was worked out to lower air resistance and the soiling of the vehicle in use. Sinotrak Rus claims fuel savings of up to 10% from the aerodynamic features combined with the new engine; the page names no reference vehicle for the figure.

Engine

The C9H page lists one engine, the MC13.54-50A of Sinotruk’s MC13 series: an in-line six-cylinder engine with turbocharging and charge-air cooling, which the page gives as meeting the Euro 5 environmental class.

Sinotrak Rus says the MC13.54-50A has a higher efficiency than earlier versions of the MC engines, which it credits to improved mixture formation in the combustion chamber, a new piston system and an improved intercooler. It says the cylinder block is made of compacted graphite iron, which it credits with 75% higher stiffness, 40% higher elasticity and 100% higher fatigue strength than ordinary cast iron, and that peak torque is available across a wide band of 900 to 1,400 rpm. How kilowatt, horsepower and rated-speed figures relate is set out in reading truck power figures.

Transmission and auxiliary brakes

No document opened names the gearbox of the C9H. The page lists two auxiliary brakes, the DRB engine brake and a hydraulic transmission retarder, which it says give smooth deceleration on long descents and on level road, take load off the service brakes and keep the brake shoes from overheating. Sinotrak Rus gives the DRB a braking power of up to 370 kW and says that at low engine speeds, 1,000 to 1,400 rpm, its effectiveness is 100 to 178% higher than that of the EVB. How engine brakes and retarders work is explained in retarders and engine braking explained.

Axles, suspension and brakes

No document opened gives an axle designation, rating or ratio, a suspension type or a service-brake type for the C9H; of the axles themselves, the page says only that they are updated. It describes a redesigned drive-axle breather that equalises pressure and keeps water and dirt out of the axle housing, a panel that gathers the pneumatic test connectors of the air circuits in one easily reached place, an axle-load indication system that shows the load on each axle of the tractor and the semi-trailer, and a brake-lining wear indicator.

Dimensions and weights

No document opened gives a wheelbase, an overall length, width or height, a kerb weight, a gross vehicle weight or a gross combination weight for the C9H. The page gives the cab dimensions listed under Cab and the tank volumes listed below.

Fuel and AdBlue tanks

The C9H page gives two fuel tanks with a total capacity of 1,300 litres, which it says give a long range between refuelling stops, and an AdBlue tank whose volume it describes as increased to 90 litres, with a filler neck placed for easy filling. What AdBlue does in an exhaust aftertreatment system is explained in SCR and AdBlue explained.

Safety and driver-assistance systems

The page lists these systems under the heading “intelligent driver-assistance systems” and marks none of them as standard or optional.

Equipment

The page also lists a rain and light sensor that switches on the headlights at dusk or on entering a tunnel and starts the wipers when it detects drops on the windscreen; keyless entry with push-button start (PEPS); a washer-fluid filler neck placed for easy filling; a battery box with an optimised position on the frame and an arrangement of the batteries and wiring inside it; a 16-metre cable that lets the rear camera of the 360° system sit at the back of the truck; and a metal mesh that keeps insects and small stones out of the intercooler core.

Source notes

All figures are from one Sinotruk document: the SITRAK C9H product page on sitrak.ru, the site of SINOTRUK’s representation in Russia, Sinotrak Rus (Russian market, undated, read on 25 October 2026), which announces the C9H as coming soon. The page names no gearbox and gives no axle designation or rating, no wheelbase, no overall dimension, no kerb weight and no gross vehicle or gross combination weight. It gives one wheel formula, 4x2, one cab, H, and one engine, the MC13.54-50A. Its cab dimension table gives thirteen values in millimetres in columns lettered A to M without saying what each letter measures. It marks none of the safety and driver-assistance systems it lists as standard or optional.
