Product Overview
The SINOTRUK HOWO T7H 6x4 Prime Mover is SINOTRUK's flagship long-distance tractor truck, designed for professional fleet operators who demand European-level performance, comfort, and reliability. The T7H combines proven MAN technology with SINOTRUK's manufacturing expertise.
At the heart of the T7H is the MC11.42-50 engine, a 10.518-liter MAN-technology inline 6-cylinder producing 420 HP at 1900 rpm and 2060 Nm of torque. This engine features BOSCH common rail injection, water-cooled turbocharger with wastegate, and electronic engine management for optimal performance across all operating conditions.
The HW25712C 12-speed manual transmission with overdrive provides the ideal gear ratio spread for efficient long-distance hauling. The transmission features aluminum housing for weight reduction and integrated oil pump for reliable lubrication in all operating positions.
The T7H cabin is a completely new design based on MAN TGA technology. It features a 4-point air suspension system, heated and ventilated leather seat with lumbar support, multi-function steering wheel with cruise control, 7-inch color LCD display, and automatic climate control with pollen filter. The high-roof sleeper configuration provides a 800mm wide sleeper berth with reading light and storage compartments.
Safety features include WABCO EBS electronic braking with ABS and ASR (anti-slip regulation), engine exhaust brake, optional hydraulic retarder, lane departure warning, and collision avoidance system. The cabin meets ECE R29 crash test standards for occupant protection.
The T7H is designed for 50-ton GCW operation with fuel-efficient powertrain matching that delivers 28-32L/100km on highway routes, making it one of the most fuel-efficient heavy tractor trucks in its class.

Frequently Asked Questions (FAQ)
Q1How does the T7H compare to European trucks like MAN or Volvo?
The T7H uses MAN TGA cabin technology and MC11 (MAN D26 derivative) engine, delivering 85-90% of European truck performance at 60-70% of the purchase price. The main differences are in brand premium, some electronic features, and dealer network density in European markets.
Q2What is the recommended service interval for the T7H?
Engine oil and filter: every 30,000 km or 500 hours with synthetic oil. Transmission oil: every 100,000 km. Rear axle oil: every 80,000 km. Air filter: every 40,000 km (standard conditions). The T7H is designed for extended service intervals to maximize uptime.
Q3Can the T7H be equipped with an automatic transmission?
Yes. The T7H can be specified with a ZF 12-speed AMT (Automated Manual Transmission) for premium fleet operations. The AMT provides smooth, automated gear changes while maintaining manual transmission fuel efficiency.
Q4What is the total cost of ownership compared to 6x4 standard models?
The T7H has approximately 25% higher purchase price but delivers 15-20% lower fuel consumption and 30% longer service intervals. For fleet operations exceeding 150,000 km per year, the T7H typically achieves 10-15% lower total cost per kilometer.
