Renault Trucks introduces new 13-liter engine for its T, T High, C and K ranges
The DE13 R is available in versions up to 540 hp with 2800 Nm torque and was designed using new materials including high strength grey iron and compacted graphite iron which provide greater robustness and durability. It incorporates several technical developments designed to optimise combustion and reduce energy loss.
Renault Trucks has launched a new DE13 R engine and a new generation of Optidriver gearboxes for its T, T High, C and K truck ranges. According to the French truck maker, these developments reduce fuel consumption and CO₂ emissions by up to 4% compared with the previous generation.
In technical terms, the DE13 R is available in versions up to 540 hp with 2800 Nm torque and was designed using new materials including high strength grey iron and compacted graphite iron which provide greater robustness and durability. It incorporates several technical developments designed to optimise combustion and reduce energy loss. Maximum cylinders pressure can now reach 250 bar, while a new fuel supply system with an external high-pressure fuel pump improves injection precision and engine efficiency.
Renault Trucks’ new 13-liter diesel engine
In addition, the DE13 R is fitted as standard with a more powerful engine brake (Optibrake+) for better driving comfort and improved vehicle control, in particular on hilly terrain. The new powertrain also leverages on fuel-reduction technologies:
- Optivision+ predictive cruise control, which uses topographical data and road signs to adapt gear shifting, acceleration and vehicle speed to road conditions.
- The Predictive Engine Stop Start system, based on predictive cruise control, automatically shuts down the engine during rolling phases when the vehicle is freewheeling (Optiroll). Essential vehicle functions remain active, and the engine restarts instantly whenever required.
For maximum energy savings and productivity, Renault Trucks also offers a Smart Racer2 version with the full range of energy-efficiency enhancements: improved aerodynamics, Optivision+, low rolling resistance tyres and advanced predictive powertrain control.
“The decarbonisation of road transport relies on several complementary levers. Alongside the acceleration of the development of our electric offer, we continue to improve the energy efficiency of our combustion-engine vehicles in order to help our customers reduce their fuel consumption, CO₂ emissions and total cost of ownership from today. This new powertrain is a concrete illustration of this approach,” commented Antoine Duclaux, President of Renault Trucks.
