Sisu Auto’s strategy is export-oriented

Petri Kananen becomes the Managing Director of Oy Sisu Auto Ab

Entrepreneur Timo Korhonen, Managing Director of Oy Sisu Auto Ab since 2010, acquired the sole ownership of Sisu Auto in 2013. Reasoning for his commitment decision was based on the strong trust in the future of the Finnish vehicle industry, as well as in his will to advance excellence of domestic product development, production, and the wide network of related sub-supply chain, and business growth through exports.

Under leadership of Mr. Korhonen Sisu Auto took a new path to the future by widening company’s portfolio from the traditional truck and military vehicle businesses to special vehicles for export market, as well as to R&D services for the vehicle industry in the evolving new markets.

The ongoing development program of Sisu Auto has required vast investments especially to R&D, and to business development in general. Notable investments include the start of co-operation with the World’s leading manufacturer of commercial vehicles, Daimler AG, and the development of the totally new SISU Polar series of vehicles, widely utilizing Mercedes-Benz components sourced from Daimler, says Timo Korhonen.

Increasing market demand thanks to good quality of SISU truck products, and respectively raised production rate, increase challenge of the task. In spite of changes that have been continuously ongoing, the consolidated business result of the current decade has been kept positive. A special acknowledgement goes to, in addition to our loyal customers, to the committed and motivated personnel of Sisu Auto: Bringing SISU back on its feet has been the common goal for the personnel, and for the loyal customers that have trusted SISU truck products through the decades, Mr. Korhonen continues.

SISU Polar series grows and stabilises its position in domestic market

Well organised and persistent work for strengthening the domestic market share has resulted in good position in the segment of most demanding tasks, such as gravel transport, road maintenance and timber transport. The remarkable R&D investment to SISU Polar series has produced, for example, the world’s first parallel diesel-electric hybrid system for a heavy-duty truck.

Another result of our R&D is the economical and strong reputation of our products, which has enabled the increase in our market share. We have now reached a stage in which every second of our new deals comes from users of competing brands. A fact that creates a good basis for future growth, too, states Sales Manager Ville Kaihu, who is responsible for the domestic sales.

Demand for Military Vehicles is increased

The changed security situation in Europe and related re-evaluation of battle plans in various countries have caused increasing demand of Armoured Military Vehicles. In response, Oy Sisu Auto Ab has focused in development of new products answering to the evolving customer requirements.


Alongside to the Armoured SISU ETP series, approximately 200 units of which are already in operational use, we have brought to market a new Armoured, lighter, highly versatile and modular SISU GTP series. The new series has already at the early stages gained well deserved fame, for example, by winning the comparative tests of Latvian Army among strong international competitors, says Sisu Defence business director, Jyri Ahonen

 SISU Special Vehicles business and related new technologies are moving ahead

Especially tough SISU Polar Super series which is intended for transporting heavy payloads on hard surfaces, and respective ETI series intended for off-road environment, have exceeded the expectations in connection with the first Customer cases, boosting the further marketing and sales activities of these product ranges. The SISU’s diesel-electric Hybrid powerline will come to these Special Vehicles in near future as a further developed, fully electric variant, reveals Sisu Auto’s Design Manager, Olli Leinonen.



SISU’s R&D services for evolving new markets are productive

SISU Engineering, the R&D services business of Sisu Auto, has already completed several delivery projects, e.g. to Chinese vehicle manufacturers JAC and BAIC. Ongoing expansion of the SISU Engineering business, as well as strengthening of co-operation with the existing Customers, and earning the trust of new Customers, are part of Sisu Auto’s long term plan, aiming to establish the R&D services business as an integral part of Sisu Auto’s business operations.

Investing in the export business is causing new share of responsibilities among the management

Timo Korhonen has steered the company to growth path, founded on the established market position in domestic market. From now on Korhonen shall, as the Group Managing Director and Chairman of the Board, concentrate on the next phase of the company’s long-term plan, in expanding the export business.

M.Sc Petri Kananen, who has been responsible for the SISU Polar business since 2017, has been nominated as the new Managing Director of Oy Sisu Auto Ab from 16.4.2019 onwards. Mr. Kananen’s new task is to be in charge of the operative management of the company, to develop the business further, and together with the group management to launch the strategic expansion campaign towards export market.

Our co-operation for several years in managing the company has convinced me of Petri’s capabilities and persistence. Therefore, I believe that Sisu Auto has great changes to continue to develop further under his management. We shall co-operate closely in future in order to rapidly boost company’s export business, Mr. Korhonen finishes.

It is a honour to become a leader of such a famous and important company, and to engage in writing the company’s future. I have had a chance to be part of the company, it’s development and growth, and related challenges almost through the whole 2010’s. Continuation of this positive development, and the progress of our company, as well as of the whole domestic vehicle industry, is an obligation for which I will do all I can, says Petri Kananen.

Export business and the consequent growth shall be a great challenge which shall require a lot also from our Partners, Suppliers, Personnel, Management and Board of the company. Implementing the changes at the same time managing and developing the already established market position shall be our key tasks, Mr. Kananen states.

Petri Kananen (32) is an experienced expert in vehicle industry

SISU Hybrid is designed to deliver maximum performance in daily tasks by added power and torque . What’s best, the SISU Hybrid offers all this and much more with lower fuel consumption and lower emissions.

SISU Hybrid is a parallel hybrid system, meaning diesel and electric motors can operate separately or together. The electric motor gets its power from supercapacitors, so the additional power is automatically at disposal as soon as energy is charged to the capacitors. The system recognizes when additional electrical power is needed alongside the diesel engine and automatically deploys the electric motor. More power can also be manually deployed whenever necessary with the PowerTouch  lever switch located on the gear lever. Capacitors enable fast energy storage and discharge. The electric charge is deployable without delay.

Benefits of the SISU Hybrid system include:

  • Extreme pulling power from 0 speeds enables easy start-up
  • Lower fuel consumption
  • Lesser emissions
  • Easy reversing and rocking with PowerTouch switch


SISU Polar -sales continue growing, and the market position is becoming stronger

The annual registration figure for Sisu Polar products in Finland, 122 vehicles, shows growth of 13% from the previous year. The increase in sales figures is even greater, resulting in record high order backlog and respectively raised production volumes for Sisu Polar truck products, giving a positive forecast for 2019.

“Our investment in the product quality and product features respond well to the increasing transported volumes, strengthening our position in the most demanding transport tasks. Sales of Sisu Polar logging trucks tripled during last year, and our market share in earth moving trucks continued growing” says Sisu Polar business director, Mr. Petri Kananen.

Within 2018, Sisu Auto brought also heavy hybrid trucks to sales and manufacturing program.
”The great interest in the market, the ongoing discussions of the carbon neutral Europe, the orders received for Sisu Hybrid trucks, as well as the feedback from Customers, all strengthen our view of having chosen the right direction” Petri Kananen states.

During this year, Sisu Auto shall keep on strengthening it’s position in logging trucks and in earth moving trucks. The strong position in domestic market enables focusing in development of the export sales, in which Sisu Auto has recently made significant approaches towards Russian markets, for instance.

SISU Polar Super truck combines the proven technology of SISU Polar product range and the special requirements set by the industry. The improved performance necessary in the challenging mine environment is based on the purpose-built and robust frame and suspension structure, as well as the task-specific Fliegl push-off body, which keeps the centre of gravity low during the transport and unloading, and allows the operation in low building environment, too. Otherwise the truck utilises the same technology basis as the rest of the Sisu Polar range. Thereby, economy and serviceability of the truck in question are optimal.

SISU Polar Super truck is very versatile and therefore suitable for different applications and end uses requiring that extra Productivity.

Pay-loads of up to 50 tons in varying operational environment.

Vuorsola Oy received a tougher SISU Hauler truck

Vuorsola Oy received a tougher SISU Hauler truck

The latest demonstration of Sisu Auto’s Customer-oriented vehicle design is the new extremely tough Hauler truck developed together with Mr. Mikko Vuorsola of Vuorsola company. The technical max weights of this new SISU Polar Hauler truck are really standout – GVW of 72 tons, and GCW of 300 tons respectively.

The new technical features of the truck include, for example, the axle weigh adjustment for the liftable 2nd front axle, the reinforced draw- and push points in rear and in front, as well as the additional cooler for the engine and for the fluid coupling. The additional cooling is necessary when operating with exceptionally heavy combination weights, in connection with low driving speeds. Hydraulics and electrics are in line with the requirements for the trailers used in special transports. SISU Polar Hauler comes with variable displacement hydraulics, which is used for special transport trailers’ suspension and steering, as well as operating the vehicles’ additional water pump and hydraulic fan.

The new Hauler supplements the selection of factory-ready SISU heavy tractors to cover also the toughest and the most demanding special transport tasks. “This is our first truck which can be taken straight to work. We at Vuorsola are especially pleased also about the top-class quality of this new product”, says Mr. Mikko Vuorsola.

SISU Polar Hybrid deliveries commence

The future of heavy duty trucks is presented in form of the first SISU Polar Hybrid timber truck at Power Truck Show 2018, Härmä, Finland at Sisu Auto´s stand U117 during 10.-11.8.2018. Later on, SISU Hybrid trucks are also shown at FinnMetko 2018 exhibition during 30.8.-1.9.2018 in Jämsä, Finland.

Sales of SISU Polar Hybrid series has got a good start, and now the first SISU Hybrid trucks are already rolling out from the Sisu Auto’s production line. The time when the Customers can take the new technology to productive use, and benefit from the advantages of the Hybrid driveline, has come. ”Every tenth of the SISU Polar Rock and SISU Polar Timber series trucks sold earlier this year have been chosen with the new Hybrid driveline solution. Thereby, these new powerful trucks shall be a common sight all around Finland during this autumn” says Sisu Auto’s Business Director, Mr. Petri Kananen.

The first generation of SISU Hybrid driveline produces a total power of more than 600 kW in parallel with the diesel engine. Torque of more than 3000 Nm is available already from the idle speed of the diesel engine, and the maximum torque of 3600 Nm in range of 1000…1800 rpm respectively. This unprecedented torque range and maximum power supplied by the parallel hybrid system increase the usability of the truck. Storing and re-using the braking energy in accelerations and hill climbing improves significantly the fuel economy of the heavy vehicle, at the same time lowering the CO2 emissions.

SISU Polar Hybrid differs from the conventional trucks with Sisu PowerControl control panel and with separate PowerTouch switch, which has been ergonomically placed in connection with the gear selector. Energy storage, the super capacitors, are located behind the cab. The energy storage does neither limit the cargo space, nor does it come in conflict with other components, or accessories. The hybrid driveline system enables, for example, start-offs without loading the clutch, as well as quick joggling and retarding functions. The hybrid system includes also an advanced start function, which can be used to start the diesel engine by the electric motor whilst the energy stored in super capacitors is in use.

Sisu Auto’s substantial investment to the product development has created the high-quality SISU Polar truck series. Now, with the newly available Hybrid driveline solution, technology of SISU Polar series becomes a real standout. Patents, applied for during the development phase of the Hybrid driveline solution to protect the new technology inventions, also tell about the innovativeness of the Sisu Auto’s R&D team. ”Alternative power lines are the future of the transport industry. Sisu Auto has now made alternative power lines available already for both, SISU Polar series of trucks, as well as for SISU special vehicles”, says Sisu Auto’s Product Manager, Mr. Teemu Puustinen.

Oy Sisu Auto Ab welcomes everyone to the exhibitions as mentioned above to see the future of heavy duty trucks. At Sisu Auto’s stand also the world’s fastest timber transport entrepreneur, Mr. Jari Halinen, shall tell more about his experiences of the totally new feeling of Power and Torque.
