Scania has unveiled Hybrid Electric Vehicles (HEV) and Plug-in Hybrid Electric Vehicle (PHEV) trucks that can be fitted with different powertrain and charging options to meet a range of applications.
The new electric GE281 works in tandem with a Scania 7.0- or 9.0-litre combustion engine to create fossil-free transport solutions for heavy trucks with demanding bodywork.
Scania’s new hybrid powertrain has been developed in-house and uses two electric motors that have been merged with the firm’s latest Opticruise gearbox generation.
The truck delivers seamless power transmission for trucks of up to 36 tonnes without support from the combustion engine.
And since the new offering will use electric power for starting and acceleration, the truck can use an engine with a lower power output – and deliver fuel savings of up to 40%.
‘GE281 something brand new’
The senior vice president at Scania Sales & Marketing, Fredrik Allard, said: “The GE281 is something brand new in the heavy truck industry.
“With this fourth generation of hybrid trucks from Scania, we have reached a point where hybrids are strong candidates for a variety of applications and operations where sustainability and smart solutions are the main priorities.
“These new hybrids have the capacity for taking on a multitude of tasks and will come out on top in all kinds of relevant comparisons.”
The latest hybrid truck can be ordered as HEVs and as PHEVs, available in P, G and L series cabs.
Hybrid trucks can be specified as rigids
The new hybrid trucks can be specified as rigids and as tractors and with a 7.0-litre DC07 engine in three power outputs – as is the 9.0-litre DC09 engine.
All Scania Euro 6 engines can run on hydrotreated vegetable oil (HVO), and some can also run on biodiesel FAME.
Scania’s GE281 offers 230kW continuously and 290kW as peak power output, while the max torque is 2,100Nm. It has six forward gears but no traditional clutch, since a planetary gear takes care of that process, providing torque interruption-free gear shifts.
This solution also provides for excellent creep drive capabilities at low speeds and the PTO can be engaged while the truck is moving, in electric as well as combustion engine mode.
‘Driving experience can be compared with a passenger car’
Mr Allard said: “The driving experience can actually be compared with what you get in a passenger car with a dual-clutch system.
“And with this solution, we can offer all the support functions that Scania customers are accustomed to, such as adaptive cruise control with active prediction and downhill speed control.
Another improvement with this solution is that the energy recuperation during deceleration is also uninterrupted, which is important since the electric machine is the primary brake source in these vehicles.”
Scania is one of the few major manufacturers committed to offering heavy commercial hybrid trucks and has been a pioneer since 2014, when a first generation was introduced with an electric range of up to 2km.
