Sisu partners to develop hybrid heavy truck powertrain

Heavy Duty Trucking  /  May 19, 2017

Finland is not usually associated with being a hotbed of cutting-edge automotive design. But Europe is leading the charge on a wide range of new transportation technologies. And the Finns are certainly playing their part in the tech wave sweeping trucking today.

Two Finnish companies, Sisu and Visedo, have developed a hybrid-electric parallel power system they say produces 1,140 horsepower and 3,687 lbs.-ft. of torque.

Sisu is a Finnish truck manufacturer. Visedo is a Finnish manufacturer of heavy-duty hybrid and electric power systems that says it developed the electric power system as a proof-of-concept vehicle that integrates the parallel hybrid drive, which draws power from both an electric motor and a diesel engine connected via the same axle.

The new system is designed to work with Mercedes-Benz OM471 and OM473 diesel engines. Diesel is the primary power source, with the electric motor kicking in during peak energy demand periods. When needed, auxiliary power is delivered by a Visedo permanent-magnet electric motor, while the mechanical powertrain is controlled by a Visedo inverter and PowerBoost DC-DC converter. Excess energy is stored in a supercapacitor, with the entire system designed to be customizable with simple vehicle integration to meet customer needs. Additional power and charging requirements are initiated automatically, allowing the driver to concentrate on the road, although an in-cab monitor allows the driver to track of the system’s functions and take control of it if needed.

The main objective for Visedo and Sisu was to reduce fuel consumption and reduce emissions, the companies said. However, they noted that the hybrid system also boosts available low-speed torque for heavy duty trucks and also enables the use of the vehicle with or without electric power since the drive line is mechanically continuous from the diesel engine to the axle.

The companies unveiled the new drive system launched at this year’s Kuljetus transport tradeshow in Finland, saying it marks an important milestone for hybrid electric power to deliver fuel savings and emissions reductions in the heavy road transport sector.  

“We’re proud to be giving Europe its first look at such a breakthrough hybrid truck drive system that’s capable of delivering breakthrough power and performance while saving fuel and reducing emissions,” said Risto Tiainen, Visedo system solutions manager. “The revolution to electrify the world’s diesel transport is already underway. After delivering pioneering hybrid and electric power for passenger buses, Visedo is proud to be powering the next generation of cleaner truck transport solutions.”

Let sumone else B the guinea pig for 10 or more years

till they get any bugs outa system (could Brake U ifn its a lemon)

n show support from the makers with a 10 year 100% warranty

Ted, Sisu builds very good trucks. I trust them to have thought this system through.

all new inventions have teethin problems th@ cost the end user time n munee

th@ why we like run n old reliable gear

aint nutn rong with new gear but sumtimes U need runs on the board to proove its OK (time & miles)

Sure U can put an new beast on a dyno n run it for 10million miles but th@ aint gunna B in the real world
