CaetanoBus has unveiled a groundbreaking series of zero-emission buses in 8.5m, 12m, and 18m lengths, targeting high-performance needs for global fleets. These battery-electric e.CityGold and hydrogen H2.CityGold models integrate advanced CATL batteries and CRRC powertrains, offering superior range and efficiency for sustainable public transport. Operators worldwide, including those seeking used zero-emission commercial vehicles, can now access scalable solutions for greener cities.[1][2][3][4]

CaetanoBus equips its new zero-emission buses with CATL BC5 LFP battery systems, featuring high-energy-density cells rated for over 4,000 charge cycles with minimal degradation. Battery capacities reach 266kWh for 8.5m models, 465kWh for 12m, and 700kWh for 18m variants, enabling extended urban operations.[2][5][1]
Hydrogen models use Toyota's Fuel Cell Stack Generation 2.5 (70kW output) paired with expanded CATL batteries: 130kWh for 12m and 170kWh for 18m buses. Both electric and hydrogen powertrains feature CRRC's 6-in-1 inverter system, integrating motor control, DC/DC conversion, and more - reducing weight by up to 70% for better efficiency.[3][5][1]
The 18m articulated buses include a Bus Rapid Transit (BRT) version with dual-side doors for high-capacity routes. Right-hand drive prototypes for markets like the UK are slated for 2026 debut.[1][2]
| Model Variant | Length | Battery Capacity (BEV) | Battery Capacity (FCEV) | Key Features |
|---|---|---|---|---|
| e.CityGold | 8.5m | 266kWh | N/A | Compact urban agility |
| e.CityGold | 12m | 465kWh | 130kWh | Balanced range/city use |
| e.CityGold | 18m | 700kWh | 170kWh | BRT high-capacity |
CRRC's collaboration brings rigorous software-in-the-loop and hardware-in-the-loop testing, ensuring top reliability. The unified platform supports seamless battery-electric or hydrogen swaps across sizes, maximizing fleet flexibility.[2][1]
Safety systems include Electronic Braking System (EBS), Tyre Pressure Monitoring (TPMS), Electronic Stability Control (ESC), and Headway Monitoring Warning (HMW). Hydrogen models offer up to 450km range with 5.5kg/100km consumption, outperforming diesel in emissions and refueling speed.[6][7]
Nuno Lago de Carvalho, CaetanoBus CCO, states: "This new generation represents the forefront of e-mobility engineering - delivering exceptional reliability, performance, and safety."[1][2]
China leads global zero-emission bus adoption, with city bus electrification nearing 100% in H1 2025 - 98% battery-electric, 1% fuel-cell. Total ZE medium/heavy-duty vehicles hit over 230,000 units in 2024, driven by stimulus and China VII standards.[4][8][9]
Chinese brands like Yutong capture 26% of Europe's ZE bus market in 2024, challenging incumbents. Battery swapping surged 94% to 29,569 units, ideal for high-utilization fleets. This growth underscores demand for high-performance zero-emission buses like CaetanoBus models in Asia's logistics hubs.[8][10][4]
CaetanoBus H2.CityGold buses operate in London with Abellio (34 units since 2020), supporting TfL's 2037 zero-emission goal for 8,000 buses. Lisbon runs e.CityGold fleets, proving reliability in dense urban settings.[5][11]
In Porto, route simulations show electric buses matching diesel performance with lower costs. Globally, ZE buses cut 1,690 tons CO2 per 12-year lifespan, equivalent to removing 27 cars from roads. Operators report 133,000 miles between maintenance vs. 45,000 for CNG - slashing downtime.[12][13][14]
- London SSE Garage: Converted to smart ZE hub for RATP Dev.[11]
- Peru Fleet: 50 electric/hybrid buses in Jan 2025, plus 150 by 2026.[15]

Zero-emission buses deliver quieter rides, instant torque for city acceleration, and reduced noise pollution. Maintenance drops due to fewer parts, with long-term fuel savings offsetting upfront costs.[13][14][16]
Fleet operators gain from energy trading via depot chargers and EMaaS models - pay-per-use including infrastructure and maintenance. In China, ZE trucks/buses doubled medium-segment share to 20.6% in 2025 Q1-Q3.[17][15]
| Benefit Category | Diesel Comparison | ZE Bus Advantage |
|---|---|---|
| Emissions | High NOx/particulates | Zero tailpipe |
| Maintenance | Frequent (45k miles) | 133k miles intervals |
| Costs | High fuel | Lower TCO long-term |
| Passenger Comfort | Noisy/vibrating | Quiet/smooth |
Transitioning to zero-emission commercial vehicles requires planning. Follow these steps for seamless integration:
1. Assess Fleet Needs: Evaluate routes, passenger loads, and refueling infrastructure - CaetanoBus offers 8.5-18m scalability.[1]
2. Choose Powertrain: Battery for depots with charging; hydrogen for long-range without stops (up to 450km).[6]
3. Pilot Test: Deploy prototypes like 2026 RHD models; monitor via CRRC systems.[1]
4. Secure Financing: Use EMaaS for zero upfront CapEx.[17]
5. Maintenance Setup: Leverage CATL's 4,000+ cycle batteries for decade-long reliability.[3]
