Yutong U12DD Double-Decker Electric Bus Redefines Urban Transit Efficiency: Specifications
The Yutong U12DD double-decker electric bus features a powerful 621 kWh battery and delivers an impressive range of up to 670 km on a single charge, setting new standards for long-range urban electric transit.

Yutong has raised the bar once again with the global debut of its next-generation Yutong U12DD double-decker electric bus, designed to meet the evolving needs of sustainable city travel.
Unveiled at Yutong’s state-of-the-art Electric Bus Intelligent Manufacturing facility in Zhengzhou, China, the new Yutong double-decker bus builds on the success of the earlier 11-meter U11DD model and reflects the company’s intensified focus on global markets and clean energy innovation.

A New Era in Performance and Battery Tech
The Yutong U12DD double-decker electric bus is powered by a formidable 621 kWh battery pack that enables an extended range of up to 670 km on a single charge — a standout figure in the electric bus segment.
Fast charging isn’t a challenge either, with dual-gun EU-standard connectors delivering a full recharge in just 2 hours at 350 kW.
Energy efficiency is a clear focus here. With an energy consumption of just 0.81 kWh/km under SORT2 testing, the 12-meter Yutong U12DD bus ensures economical operation while minimizing its carbon footprint.

Uncompromising Safety and Smart Engineering
The U12DD incorporates Yutong’s proprietary YESS battery safety system, offering multilayer protection against electrical hazards. Its battery, motor, and controller systems are built to IP68 and IP6K9K standards, making them extremely resilient against dust, water, and environmental wear, essential for global deployment.
A lightweight, all-aluminum frame reduces the bus’s weight by 1,300 kg, contributing to better efficiency and easier handling. In tandem, silicon carbide (SiC) controllers and variable-frequency pumps cut energy usage by an additional 10%.
Advanced anti-corrosion treatments and electrocoating push the bus’s structural life expectancy to an impressive 20 years or 2 million kilometers, making it a long-term asset for fleet operators.

Passenger Comfort Meets Intelligent Management
Inside the cabin, the Yutong U12DD double-decker electric bus is built to move cities. With a seating capacity of up to 120 passengers, a smart three-door entry system, and dual staircases, passenger flow is smooth and intuitive.
A powerful 52,000 kcal/h HVAC system ensures quick climate control across both decks — a key factor in delivering year-round comfort in diverse climates.
What’s more, the vehicle integrates Yutong’s Link+ intelligent fleet management system, which offers real-time vehicle tracking, diagnostics, and dispatch planning — a boon for operators focused on efficiency and uptime.
