This is the first Diesel V6 engine developed and produced by the Alliance Renault Nissan. It equips upper-range vehicles to meet the growing worldwide demand for engines that are powerful and yet fuel and CO2 efficient.
The new V6 Diesel engine is a technological high displacement multi-valve V powertrain, which means it offers a high level of performance and driving pleasure. The new powertrain has the highest level of torque in the Renault lineup with 450nm. It therefore allows very fast accelerations either from 0 to 100km/h (7.30 seconds on Laguna Coupe dCi 235) or from 80 to 120 km/h (6.10 seconds on the same vehicle). Additionally, on Laguna Coupe, the new Diesel V6 posts 235hp, which makes it Renault's second most powerful engine offer after the 3.5l gas engine (245hp). Further versions of this engine will be commercialized with more power and more torque, as it can generate up to 265hp and 550nm when put longitudinally on a car.
The new V6 dCi engine derives from the 4-cylinder in-line 2.0 dCi launched in 2005. They share components, but the combustion chamber design has been optimized to improve the trade-off between emission levels and fuel efficiency. On Laguna Coupe dCi 235, it emits 192g of C02 per kilometer, which is in line with most of the best German engine makers. Of course, the new V6 will be fitted with particle filters and a SCR (Selective Catalystic Reduction) catalyst, to make it one of the cleanest Diesel engines in the world. Very low noise levels are the result of a joint optimization of powertrain engine base, injection and tuning strategies.
