12.8 liter, in-line 6 cylinder

TAD1381VE is a powerful, reliable and fuel efficient off-road diesel engine built on the Volvo in-line six concept. 

Low cost of ownership
World class fuel efficiency combined with a reliable Exhaust Aftertreatment System (EATS) gives high uptime as well as low cost of ownership.

Power and torque
Maximum torque is reached at low rpm and continues to rated power. The power and torque layout ensures the engine to operate in a wide engine speed range.

Low exhaust emission 
Chosen engine design combined with optimized DPF/SCR technology ensures that TAD1381VE complies with EU Stage V emissions.

Compact and simple installation 
System concepts selected by Volvo lowers amount of cooling capacity needed hence minimizing radiator size. Interfaces are compatible with engines of earlier legislations.
