On August 12, Chery officially announced the world's first mass-produced diesel hybrid pickup, named RELY Hi800. The vehicle features a 2.5T diesel hybrid system with a P1+P2.5 intelligent hybrid architecture, an engine thermal efficiency of 47%, and comes equipped with the Lingxi smart cockpit and Falcon ADAS. It will officially launch in Q4 2026, with the overseas name Stockman.
World's First Mass-Produced Diesel Hybrid Pickup: Filling a Market Gap
On August 12, Chery officially named its global first mass-produced diesel hybrid pickup RELY Hi800 (previously codenamed Weilin P3X). As the world's first diesel hybrid pickup to reach mass production, the vehicle will officially hit the market in Q4 2026, with the overseas name Stockman. It will form a dual gasoline-diesel product matrix alongside the gasoline hybrid Zongheng F700.
This naming reflects Chery's precise grasp of the pickup electrification trend. While the pickup market is rapidly transitioning to new energy, the industry has primarily focused on gasoline hybrid and pure-electric routes, with only a few 48V mild-hybrid diesel models available. A mass-producible dedicated diesel hybrid system has long been absent from the market. Yet diesel vehicles account for over 70% of the global pickup market, with heavy-load, long-distance, and off-road users having strong demand for diesel power. The RELY Hi800 seizes this differentiated opportunity.
The name itself reveals the product's core identity: H for Hybrid, indicating the diesel hybrid route; i for Intelligence, signaling this is not merely a brute-force work truck; and 800, resembling the infinity symbol, representing boundless expansion in power and application scenarios.
Dedicated Platform: Rejecting the "Oil-to-EV" Compromise
The RELY Hi800 is built on the Weilin Kaitian Platform, the world's first "intelligent new-energy full-scenario technology platform" designed specifically for pickups. Unlike the common industry practice of adapting generic passenger vehicle architectures, this platform breaks free from the traditional pickup's "single-attribute" limitation. Its highly flexible modular architecture covers everything from economy to commercial, passenger-oriented, and high-end off-road variants, while supporting pure-electric, hybrid, and range-extender powertrains.
For pickup users, this means the platform provides hardware support across diverse scenarios—from heavy construction loads to long-distance overland expeditions to daily urban commuting—without forcing compromises between power and fuel consumption. This solid foundation enables the powerful diesel hybrid system and comprehensive intelligent features to perform at their full potential.
2.5T Diesel Hybrid Powertrain: Endurance Meets Explosive Power
The RELY Hi800's biggest technical highlight is its 2.5T diesel hybrid system. Traditional diesel pickups excel in endurance and range but suffer from sluggish starts and slow low-speed response. Chery's P1+P2.5 intelligent hybrid architecture addresses these weaknesses head-on.
The system centers on a newly developed 2.5T dedicated hybrid diesel engine featuring high-pressure common-rail direct injection, variable-geometry turbocharging, and intelligent thermal management, achieving a class-leading thermal efficiency of 47%. The P2.5 motor is integrated into the transmission input shaft, providing four-speed direct-drive capability that significantly broadens the engine's efficient operating range. The addition of a high-power motor perfectly compensates for traditional diesel engines' inherent shortcomings in throttle response, low-end torque, and high-speed re-acceleration—creating a synergistic combination of diesel endurance and electric instant torque.
Chery also revealed that the vehicle features an intelligent four-wheel-drive system with three differential locks and multi-mode off-road driving programs adapted to sand, mud, and steep slopes.
Intelligence: Breaking the "Tool-First, Tech-Last" Stereotype
The RELY Hi800's intelligence capabilities are equally impressive. Rather than simply borrowing existing passenger car solutions, Chery conducted in-depth research into real pickup user scenarios for exclusive development.
The vehicle deeply integrates Chery's mature "Lingxi Smart Cockpit" and "Falcon ADAS" technology platforms, shattering the traditional pickup stereotype of prioritizing mechanics over technology. The cockpit features a 15.6-inch floating central display and full-LCD instrument panel with a large AR-HUD, wrapped in extensive leather with heated/ventilated/massage seats and an in-car hot/cold box. The ADAS system, trained on massive real-world driving data, delivers full-scenario NOA specifically tuned for heavy loads and long wheelbases.
Rugged Off-Road Design: Balancing Passenger Appeal and Utility
Exterior-wise, the RELY Hi800 adopts a retro rugged boxy design with straight, powerful lines. The front features a rounded rectangular horizontal grille with an illuminated RELY badge, flanked by signature round LED headlights with daytime running light rings—a fusion of retro style and modern lighting technology. The front bumper carries a high-strength metal anti-scratch guard with air导流 channels on both sides.
The side profile is square and regular, with factory roof racks and fixed side steps, plus optional off-road AT tires and black multi-spoke forged wheels. The rear features vertically arranged tail lights and a wide, flat tailgate for easy loading. Black anti-scratch wheel arches handle gravel impacts on unpaved roads, balancing passenger-car aesthetics with pickup practicality.
Market Outlook: Dual Gasoline-Diesel Strategy
The RELY Hi800's launch will pair with the gasoline hybrid Zongheng F700 to form a "gasoline and diesel dual-track" complementary matrix, completing Chery's new-energy pickup lineup. As domestic pickup new-energy penetration continues to rise with no mature diesel hybrid products yet available, Chery's dual-track approach captures both commercial/off-road users' diesel needs and addresses traditional diesel vehicles' high fuel consumption pain points through hybrid technology.
The vehicle wasn't rushed to market. Since its debut at last year's Chengdu Auto Show, Chery chose to patiently refine the product through extreme environment testing, technical detail polishing, and all-scenario user experience optimization—using hundreds of thousands of kilometers of multi-terrain real-world testing to build a solid quality foundation. This steady approach precisely reflects Chery's determination to redefine the new-energy pickup.
