The new generation of turbocompound engines allows Renault Trucks’ high-end trucks to save up to ten percent on fuel consumption. Advanced engine and fleet management solutions also help operators improve the efficiency of their vehicles and fleets.
Renault Trucks now offers 11-litre and 13-litre diesel engines with turbocompound technology in the T, T High, C and K ranges, which provide a reduction in fuel consumption of up to 10% compared to the previous generation.
The new thrusters meet the Euro VI Step E emissions standard, relying on patented Wave Piston technology to improve combustion.
With the re-routing of the flames inside the combustion chamber, the solution allows a better use of the available oxygen and, therefore, a better combustion. The engines are also equipped with new injectors, more precise and adapted to the new combustion.
To improve efficiency, Renault Trucks sought to reduce friction losses: the connecting shafts, pistons and crankshaft were redesigned and the control of gases in the crankcase was optimised.
In addition, a new high-performance, ball-bearing turbocharger has also been developed that offers improved response time and a variable-flow oil pump in combination with low-viscosity oil.
Renault Trucks also opted for an optimized after-treatment system and a new engine control unit.
For maximum performance, Renault Trucks’ T, T High and C trucks can be optionally equipped with the DE13 TC engine with Turbo Compound technology, already known from the Volvo FH, which provides a significant reduction in consumption without compromising on maneuverability or commercial speed.
An additional turbine, located downstream of the turbocharger, converts the residual energy from the exhaust gases into mechanical energy that is transmitted to the crankshaft in the form of additional engine torque.

The turbocompound thus allows higher levels of torque to be achieved at lower engine speeds. On the motorway, when using the cruise control (cruise control) and uphill, it will be possible to maintain a constant speed without shifting down.
The new trucks in the T, T High and C ranges from Renault Trucks receive a new generation of the new generation Optidriver automated gearbox, which incorporates a new calculator, new control software and a new clutch actuator that allow smoother and more efficient shifts. faster.
With the aim of optimizing consumption, Renault Trucks has adopted the Smart Torque Control solution, which maximizes time in the area with maximum engine efficiency without penalizing manoeuvrability.
The French brand also continues to improve the Optivision predictive cruise control, which uses road topography to optimize gear changes and fuel savings.
The brand also offers solutions to support carriers in their efforts to monitor and improve the fuel consumption and CO2 emissions of their fleets.
The Optifleet fleet management software (Check module) controls the fuel consumption of each vehicle and analyzes driving styles to identify areas of possible intervention aimed at reducing consumption. On the other hand, Renault Trucks has developed a comprehensive training program based on the principles of rational driving to ensure that fuel consumption is kept under control.
