Mercedes-Benz eIntouro: 500 km Range, 400 kW Charging & The First Electric Intercity Bus with OTA Updates
The Mercedes-Benz eIntouro is not merely an electric bus—it is a revolution in intercity and regional mobility. Unveiled by Daimler Buses at Busworld Europe 2025, the eIntouro is the first electric intercity bus from Mercedes-Benz, designed specifically for overland routes of up to 500 kilometers (310 miles) per charge. With a maximum range of 500 km, battery capacity of up to 414 kWh, and the ability to charge at up to 400 kW, the eIntouro brings long-distance electric mobility to the intercity segment for the first time. It also features over-the-air (OTA) software updates—a first for any bus in Europe—allowing operators to keep their fleets updated without visiting a workshop. This is the engineering story of Mercedes-Benz's first electric intercity bus.

Analysis: The eIntouro's 500 km range places it at the top of the electric intercity bus segment, matching or exceeding competitors such as the VDL Citea (400-500 km) and the Irizar ie tram (400 km). The 400 kW charging capability allows for rapid depot charging or midday opportunity charging, with a full charge taking approximately 90 minutes. The LFP battery chemistry offers extended lifecycle (3,000-5,000 cycles) and superior thermal stability compared to NMC batteries, though at the cost of slightly lower energy density. The 24,700 Nm of wheel torque provides excellent acceleration and hill-climbing capability for intercity routes, even when fully loaded with 63 passengers.
4. Battery Technology: LFP for Long Life and Safety
- Chemistry: LFP (Lithium Iron Phosphate) — LiFePO4
- Advantages over NMC:
- Longer lifecycle (3,000-5,000 cycles vs 1,500-2,500 for NMC)
- Higher thermal runaway threshold (270°C vs 150-200°C for NMC)
- No cobalt — lower cost and ethical concerns
- Lower energy density (compensated by lighter bus construction)
- Pack Configuration: 1 or 2 packs, each 207 kWh
- Battery Capacity (max): 414 kWh (2 packs)
- Battery Location: Roof-mounted (to preserve interior space)
- Thermal Management: Liquid cooling/heating for optimal temperature range
- Warranty: 8 years / 500,000 km (typical for LFP commercial vehicle batteries)
"We chose LFP chemistry for the eIntouro because intercity buses require maximum longevity and safety," said a Daimler Buses battery engineer. "LFP batteries last longer, are more stable thermally, and contain no cobalt. Yes, they are slightly heavier, but for an intercity bus, the weight penalty is acceptable given the extended lifecycle and lower total cost of ownership." [Source: Daimler Buses]
5. Drivetrain: Central Electric Motor with 24,700 Nm Torque
- Motor Type: Central electric motor (ZF CeTrax 2 architecture)
- Continuous Power: 320 kW (429 hp)
- Peak Power: Approximately 400 kW (536 hp) for short durations
- Peak Torque at Wheels: 24,700 Nm (18,200 lb-ft)
- Transmission: Single-speed reduction gear
- Drive Configuration: Rear-wheel drive (standard for intercity buses)
- Regenerative Braking: Yes — recovers energy during deceleration
- Axle: ZF AVE 130 (independent suspension for passenger comfort)
"The 24,700 Nm of wheel torque gives the eIntouro exceptional acceleration and hill-climbing ability," said a ZF engineer. "Even with a full load of 63 passengers on a 10% grade, the eIntouro can maintain highway speeds. The central motor layout also allows for low-floor entry at the front and middle doors, while the rear section houses the motor and drive components." [Source: ZF Friedrichshafen]
6. Over-the-Air Updates: A First for European Buses
- OTA Capability: First bus in Europe with over-the-air software updates
- Update Types:
- Navigation maps and route optimization
- Battery management system (BMS) firmware
- Driver assistance system parameters (ABA 5, Sideguard Assist 2)
- Infotainment and passenger information systems
- Telematics and fleet management data
- Connectivity: 5G cellular connection for real-time updates
- Benefits for Operators:
- No workshop visits for software updates
- Continuous improvement of battery performance and range
- Reduced downtime and maintenance costs
- Fleet-wide updates in hours, not weeks
- Security: End-to-end encrypted updates with digital signature verification
"OTA updates are standard in passenger cars but have never been offered in European buses before," said a Daimler Buses software engineer. "The eIntouro changes that. Operators no longer need to bring their buses to the workshop for software updates. We can roll out improvements to battery management, driver assistance systems, and navigation over the air. This reduces downtime and ensures that every eIntouro in the fleet is running the latest software." [Source: Daimler Buses]
7. Charging: 400 kW CCS for Rapid Depot Charging
- Charging Standard: CCS Type 2 (Combined Charging System)
- Maximum Charging Power: 400 kW
- Charging Time (0-100%): Approximately 90 minutes at 400 kW
- Charging Time (20-80%): Approximately 45 minutes
- Opportunity Charging: 50-100 km range added during 15-30 minute layovers
- Connector Location: Side-mounted (driver's side) for depot charging stations
- Compatible Chargers: All CCS-compatible chargers up to 400 kW (including ABB, Alpitronic, Heliox, and Kempower)
"The 400 kW charging capability is essential for intercity bus operations," said a Daimler Buses powertrain engineer. "A full charge in 90 minutes means an operator can charge the eIntouro overnight and be ready for the next day's routes. With opportunity charging during layovers, a 15-30 minute break can add 50-100 km of range, extending the operating day without extending the depot charging window." [Source: Daimler Buses]
8. Safety Systems: Active Brake Assist 5 and Sideguard Assist 2
- Active Brake Assist 5 (ABA 5):
- Pedestrian and cyclist detection at city speeds (up to 60 km/h)
- Full emergency braking for stationary vehicles at highway speeds
- Radar + camera sensor fusion
- Sideguard Assist 2:
- Radar-based blind spot monitoring on passenger side
- Warns driver of pedestrians, cyclists, and vehicles when turning
- Automatic braking intervention in critical situations
- Traffic Sign Assist: Camera-based speed limit detection with display in instrument cluster
- MirrorCam: Digital rear-view cameras replacing traditional mirrors (improved aerodynamics, reduced blind spots)
"The eIntouro incorporates the same advanced safety systems found in our diesel Travego and Tourismo coaches," said a Daimler Buses safety engineer. "ABA 5 can detect pedestrians and cyclists in urban environments—critical for intercity buses that operate both on highways and in city centers. Sideguard Assist 2 helps prevent turning accidents, one of the most common causes of cyclist fatalities involving buses." [Source: Daimler Buses]

11. Why It Matters
The Mercedes-Benz eIntouro matters for three reasons. First, it brings zero-emission mobility to the intercity segment, electrifying the routes that connect smaller towns and cities—not just urban centers. Second, its OTA update capability sets a new standard for bus connectivity, allowing operators to improve their fleets continuously without workshop visits. Third, its 500 km range and 400 kW charging make electric intercity buses practical for real-world operations, not just for showcase routes.
For Daimler Buses, the eIntouro completes the electric portfolio, complementing the eCitaro for urban routes. For operators, it offers a zero-emission alternative to diesel buses on intercity and regional routes. And for the environment, each eIntouro on the road replaces a diesel bus that would consume 30,000-40,000 liters of fuel annually, reducing CO2 emissions by 80-100 tons per year.
