About this generation

The Sisu Polar was introduced in 2011 as Sisu Auto's new heavy-duty truck range and successor to the E-Series. Developed around a heavy-duty Sisu chassis and Mercedes-Benz components, Polar combines a Mercedes-Benz-derived cab and powertrain technology with Sisu axles, frames, suspension and steering. The range is designed primarily for demanding Nordic applications including heavy haulage, logging, construction, road maintenance, mobile cranes and machinery transport.
