After upgrading engines in the larger ranges, with both the DE11 and DE13 engines last November, Renault Trucks has turned its attention to the smaller-cabbed versions. This means that by 2023, the manufacturer’s new engine optimisation, a new gearbox and the Fuel Eco+ pack, the Renault Trucks D, D Wide and C 2.3 m 2023 are set to reduce fuel consumption and the associated CO2 emissions by up to 10%.
The 2023 models of the Renault Trucks D Wide and C 2.3 m will be fitted with the new DE11 engine. This features patented Wave Piston technology which, by redirecting the flames inside the combustion bowl, optimises use of the available oxygen, thereby improving combustion. New injectors with improved precision are also being fitted to the engine. To boost efficiency, Renault Trucks has also worked on reducing friction loss: the connecting rods, pistons and crankshaft have been redesigned and crankcase gas control has been optimised. A new high-performance ball-bearing turbocharger with improved response time and a variable flow oil pump combined with low-viscosity oil have also been developed. Renault Trucks has also opted for an optimised post-treatment system and a new engine control unit.
The Renault Trucks D Wide and C 2.3 m are also equipped with the new generation Optidriver gearbox. As an option, the Eco mode allows for a further reduction in fuel consumption. Lastly, an additional 5% reduction in fuel consumption can be achieved with the Fuel Eco+ Pack, which includes a roof deflector, side deflectors, a disengageable compressor and automatic engine shutdown after three minutes. All these technologies combined provide a fuel saving of 10% compared with the previous generation of Renault Trucks D Wide and C 2.3 m.
Renault Trucks D with 5 and 8 litre engines are fitted with a new 8-speed gearbox, called Optishift. Fully automatic, it offers enhanced driving comfort with better handling at low speeds and improved fuel efficiency. The new Optishift automatic gearbox is available as an option on the Renault Trucks D 4×4. The Eco mode is also available as an option for a further reduction in fuel consumption.
Last but not least, the Eco+ Fuel Pack provides additional fuel savings.
The combination of all these technologies means that fuel savings of 9% can be achieved compared with the previous generation of the Renault Trucks D. Driver comfort is one of the manufacturer’s main concerns and has also been improved on the Renault Trucks distribution range.
For increased safety, the Renault Trucks D, D Wide and C 2.3 m are equipped with the BirdView system: four cameras placed outside the vehicle provide a panoramic view in real time on a 7″ LCD screen. This gives the driver an all-round view of the surrounding area in a single image and without blind spots, reducing the risk of collision.
For perfect visual and on-board comfort, the interior of the Renault Trucks D, D Wide and C 2.3 m has been redesigned. The seats, bunks and benches are covered in a new fabric, in line with the new cab harmony, and control buttons have a new white backlight.
