SMALL BUT POWERFUL The 2-cylinder unit injector diesel engine (M12 UI) of STEYR MOTORS is characterized by a horizontal parallel twin piston configuration resulting in one of the most compact products on the market regarding the power output. The M12 UI was created to work perfectly even under extreme conditions. It is proven and tested according to several civilian and military standards including high altitude requirements, varying fuel qualities, tough environmental conditions and other challenging requirements. Due to our vast experience in tailored engineering, the 2-cylinder unit...

MADE FOR EXTREME CONDITIONS FEATURES Monoblock design engine (M12 CR) is the ability to run under toughest ambient conditions as Parallel twin DI diesel engine for instance sand, dust, low fuel quality, temperature, shock/rough terrain. Reliable unit injector technology The operational temperature comprises a range from -32 °C to +49 °C, but can be extended to -46 °C with a preheater. In short, the 2-cylinder Fully mass balanced unit injector is the first choice for demanding environmental conditions and Small, lightweight and fuel efficient military applications. Multifuel capable The main...

A COMMON RAIL WITH UNCOMMON ABILITIES The common rail version of the 2-cylinder diesel engine (M12 CR) inherited the striking characteristics of the M12 UI, but in addition has been particularly optimized to run the new STEYR MOTORS E-machine. Based on the proven Monoblock design, this horizontal parallel twin features direct common rail injection, a mass balancing system for smooth operation and an intercooler for fuel efficiency and low emission usage. The M12 CR is turbocharged (single stage, wastegate) and provides up to 40 kW mechanical 511.1 output. Besides the combination with the...

M12CR REX – A COMPACT POWER PACK The combination of the M12 CR with an e-machine, especially our STEYR E1, has proven as a very attractive range extender solution for electric applications. It increases the driving range, thus granting higher flexibility, and provides dynamic performance whilst guaranteeing a smooth and calm operation. Moreover, the M12 CR REX is lighter and more easily transportable than typical range extender solutions and, consequently, enables a weight reduction if the power unit is not needed and temporarily removed. Thanks to the extremely compact assembly of engine,...
