TAD1375 is a powerful, reliable and economical 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 gives high uptime as well as low cost of ownership. No downtime for regeneration or decreased service intervals.

Compact and simple installation
SCR technology selected by Volvo does not increase amount of cooling capacity needed. As optional equipment all material needed in order to install the
engine can be ordered from Volvo Penta. Installation guidelines as well as drawings and CAD models are easy to access. The result is an engine and aftertreatment system that is easy to install with minor
impact on existing machine layout.

Durability & low noise
Long experince with SCR systems in combination with base engine development reduces risk of downtime. Wellbalanced to produce smooth operation with low noise.

Power and torque
Maximum power and torque available at low rpm. As a result noice as well as fuel consumption is very low. Useful engine speed for the TAD1375VE is due to power and torque layout very flexible.

Low exhaust emission
Efficient injection as well as robust engine design in combination with optimised SCR technology and a light EGR contributes to excellent combustion and low
fuel consumption. TAD1375VE complies with EU Stage IV / EPA Tier 4f emissions.

Easy service & maintenance
Easily accessible service and maintenance points contribute to the ease of service of the engine. As optional equipment possible to remote mount filters and service points.
