Scania Introduces Plug-In Hybrid Powertrain for Buses and Coaches











In a significant step towards greener public transportation, Swedish automotive giant Scania, under the umbrella of Volkswagen Group, has revealed its pioneering plug-in hybrid platform for buses and coaches. This development underscores a growing trend in the automotive industry to integrate hybrid technologies into larger vehicles, aiming to curtail environmental impact, particularly within congested city centers where stringent emission regulations are increasingly being enforced.
The newly introduced powertrain is engineered to cater to both urban buses operating on shorter routes and long-haul coaches. Scania emphasizes that the system offers maximum benefits for the latter, enabling these vehicles to travel extended distances efficiently. At its core, the setup features an advanced 13-liter diesel engine, paired with a robust high-voltage battery and two electric motors seamlessly integrated into the automatic transmission system.
This innovative combustion engine boasts an 8% increase in efficiency compared to its predecessors and is designed to meet the forthcoming Euro 7 emission standards, showcasing Scania's commitment to future-proofing its fleet. The 89-kilowatt-hour battery, developed and manufactured in-house by Scania, provides an impressive all-electric driving range of up to 50 miles (approximately 80 kilometers) on a single charge.
For charging, the plug-in hybrid bus supports fast DC charging, capable of accepting 130 kilowatts of power at 200 amps through a CCS2 port conveniently located on the vehicle's right side. Additionally, the system offers the flexibility to recharge the battery using the diesel engine as a generator, ensuring continuous operation even when external charging infrastructure is not readily available.
The dual electric motors collectively generate 389 horsepower (290 kilowatts), complementing the diesel engine which is available in two power output variants: 420 hp or 460 hp. This hybrid configuration allows the bus to operate on diesel for intercity travel and smoothly transition to electric power upon entering urban zero-emission zones, significantly reducing local air pollution. Drivers can also utilize Scania's advanced geofencing feature to automate this power source transition, optimizing efficiency and compliance.
Scania's plug-in hybrid system is versatile, offered across various bus and coach body sizes, with both four-wheeled and six-wheeled chassis options. The six-wheeled models further enhance maneuverability with the inclusion of rear-wheel steering. While Scania joins a select group of manufacturers offering PHEV buses, it solidifies its position as a frontrunner in sustainable public transport solutions alongside companies like Poland’s Solaris and China’s King Long, which also provide similar hybrid urban transport options.
As industries worldwide strive to minimize their carbon footprint, plug-in hybrid and extended-range powertrains are rapidly gaining traction. Although fully electric buses and trucks are becoming more prevalent, the hybrid approach often presents a more immediate and cost-effective pathway to reduced emissions, bridging the gap towards a fully electric future for heavy-duty vehicles.
